Navigating Pagespeed Insights Interface

Accessing PageSpeed Insights is straightforward ● simply navigate to the PageSpeed Insights website and enter your website’s URL. The tool analyzes your page and generates a detailed report, presenting data for both mobile and desktop versions separately, reflecting the mobile-first indexing approach. The interface is divided into key sections:

1. Performance Score ● A numerical score out of 100, summarizing your page’s overall performance. While a high score is desirable, focus more on the CWV metrics themselves. Aim for scores in the “Good” range for CWV.
2. Core Web Vitals Assessment ● This section clearly indicates whether your page passes the CWV assessment. It shows the status (Good, Needs Improvement, Poor) for LCP, FID, and CLS based on real-world Chrome User Experience Report (CrUX) data, if available, or lab data if CrUX data is insufficient.
3. Field Data (CrUX) ● Real-world performance data collected from Chrome users who have visited your page. This is the most accurate representation of user experience. If available, prioritize field data over lab data.
4. Lab Data (Lighthouse) ● Performance metrics Meaning ● Performance metrics, within the domain of Small and Medium-sized Businesses (SMBs), signify quantifiable measurements used to evaluate the success and efficiency of various business processes, projects, and overall strategic initiatives. measured in a controlled lab environment. Useful for identifying specific optimization opportunities when field data is limited or unavailable.
5. Opportunities ● Actionable recommendations to improve your page’s performance. These are prioritized by potential impact and are crucial for guiding your optimization efforts.
6. Diagnostics ● Additional insights into performance issues, providing more technical details.
7. Passed Audits ● A list of performance best practices your page already adheres to, highlighting areas of strength.

Interpreting Cwv Metrics in Pagespeed Insights

The heart of PageSpeed Insights for CWV optimization lies in understanding and interpreting the CWV metrics. Focus on the ‘Core Web Vitals assessment’ section and the individual metrics:

• Largest Contentful Paint (LCP) ● Pay attention to both field and lab LCP values. If field data shows “Needs Improvement” or “Poor,” investigate the ‘Opportunities’ section for LCP-related recommendations like “Eliminate render-blocking resources,” “Preload Largest Contentful Paint image,” or “Optimize images.”
• First Input Delay (FID) ● FID is primarily a field metric. If field FID is problematic, look for ‘Opportunities’ related to “Reduce JavaScript execution time” or “Minimize main-thread work.” High FID often points to JavaScript-heavy pages.
• Cumulative Layout Shift (CLS) ● Check both field and lab CLS. If CLS is high, the ‘Opportunities’ section will likely suggest “Optimize image dimensions,” “Reserve space for ads,” or “Avoid non-composited animations.” CLS issues are often visual and require careful layout adjustments.

For SMBs, the initial audit is not about achieving perfect scores immediately. It’s about gaining a clear understanding of current CWV performance, identifying problem areas, and prioritizing optimization efforts. PageSpeed Insights provides the diagnostic information needed to move forward strategically.

Actionable Steps After Initial Audit

Following your initial PageSpeed Insights audit, take these actionable steps:

1. Document Baseline Metrics ● Record your initial CWV scores (both field and lab) for mobile and desktop. This baseline is crucial for tracking progress and measuring the impact of your optimization efforts.
2. Prioritize Mobile CWV ● Given mobile-first indexing, prioritize optimizing mobile CWV scores. Analyze mobile PageSpeed Insights results first.
3. Focus on “Opportunities” ● The ‘Opportunities’ section is your optimization roadmap. Start addressing the top opportunities, prioritizing those related to LCP, FID, and CLS.
4. Start with Quick Wins ● Look for easily implementable opportunities like image optimization or enabling browser caching (often suggested in ‘Opportunities’). These quick wins can provide immediate, noticeable improvements.
5. Don’t Chase Perfect Scores Initially ● Aim for “Good” CWV status first. Incremental improvements are more sustainable and manageable for SMBs than striving for unrealistic perfection from the outset.
6. Regularly Re-Audit ● After implementing optimizations, re-run PageSpeed Insights to track improvements and identify new opportunities. CWV optimization is an ongoing process.

PageSpeed Insights is not just a diagnostic tool; it’s an ongoing guide for CWV optimization. For SMBs, it democratizes access to website performance Meaning ● Website Performance, in the context of SMB growth, represents the efficacy with which a website achieves specific business goals, such as lead generation or e-commerce transactions. analysis, providing the data needed to compete effectively online. This initial audit is the foundation upon which a successful CWV optimization strategy is built.

Overlooking Mobile Optimization

Pitfall ● Focusing primarily on desktop performance while neglecting mobile CWV. Given Google’s mobile-first indexing, this is a critical error.

Impact ● Poor mobile CWV scores negatively impact mobile search rankings, which constitute a significant portion of web traffic. Desktop optimizations alone won’t suffice.

Solution ● Always prioritize mobile CWV optimization. Use PageSpeed Insights to analyze mobile and desktop performance separately. Implement mobile-specific optimizations, such as responsive design, mobile image optimization, and streamlined mobile user flows.

Ignoring Field Data

Pitfall ● Relying solely on lab data (Lighthouse) and neglecting field data (CrUX) in PageSpeed Insights.

Impact ● Lab data provides valuable diagnostic information, but field data reflects real user experiences. Ignoring field data can lead to optimizations that don’t improve actual user-perceived performance.

Solution ● Prioritize field data whenever available. CrUX data represents real-world CWV performance. Use lab data to investigate and address issues identified in field data, but always validate optimizations with field data improvements.

Treating Cwv as One-Time Fix

Pitfall ● Viewing CWV optimization as a project with a definitive end, rather than an ongoing process.

Impact ● Websites are dynamic. Content changes, updates, and third-party integrations can negatively impact CWV over time. One-time optimizations are not sustainable.

Solution ● Implement continuous CWV monitoring. Regularly re-audit with PageSpeed Insights, especially after website updates. Integrate CWV monitoring into your website maintenance workflow. Use tools like Lighthouse CI for automated, ongoing tracking.

Complex Technical Overhauls First

Pitfall ● Starting with complex, technically demanding optimizations instead of focusing on quick wins.

Impact ● Overwhelming technical projects can drain resources and delay tangible CWV improvements. SMBs may lose momentum and become discouraged.

Solution ● Prioritize quick wins first. Implement easy optimizations like image compression, browser caching, and deferring non-critical JavaScript. These provide immediate, noticeable improvements and build momentum for tackling more complex issues.

Lack of Clear Cwv Goals

Pitfall ● Embarking on CWV optimization without setting specific, measurable, achievable, relevant, and time-bound (SMART) goals.

Impact ● Without clear goals, optimization efforts can become aimless and inefficient. It’s difficult to measure success and allocate resources effectively.

Solution ● Define SMART CWV goals. For example ● “Reduce mobile LCP to under 2.5 seconds within two months.” Track progress against these goals. Celebrate milestones to maintain motivation and focus.

Ignoring Third-Party Scripts

Pitfall ● Focusing solely on first-party code and neglecting the impact of third-party scripts (ads, analytics, social media widgets) on CWV.

Impact ● Third-party scripts can significantly degrade CWV, especially LCP and FID. Ignoring them undermines optimization efforts.

Solution ● Audit and optimize third-party scripts. Defer loading non-critical scripts, lazy-load ads, and consider asynchronous loading. Regularly review and prune unnecessary third-party scripts.

Not Leveraging Available Tools

Pitfall ● Attempting manual CWV optimization without fully utilizing free and accessible tools like PageSpeed Insights and Lighthouse.

Impact ● Manual optimization without data-driven insights is inefficient and less effective. Tools provide critical diagnostics and recommendations.

Solution ● Fully leverage PageSpeed Insights and Lighthouse for audits, diagnostics, and optimization guidance. These tools are designed to simplify CWV optimization for all website owners, including SMBs.

Optimize Images for Speed

Impact on CWV ● Directly improves Largest Contentful Paint (LCP) by reducing image loading times. Also indirectly benefits Cumulative Layout Shift (CLS) by ensuring images have defined dimensions.

Actionable Steps:

1. Compress Images ● Use online image compression tools (like TinyPNG, ImageOptim) to reduce file sizes without significant quality loss. Aim for WebP format for superior compression.
2. Resize Images ● Ensure images are appropriately sized for their display dimensions. Avoid serving large images that are scaled down in the browser.
3. Lazy-Load Offscreen Images ● Implement lazy loading for images below the fold. This defers loading until they are about to enter the viewport, speeding up initial page load and LCP.
4. Use CDNs for Images ● Content Delivery Networks Meaning ● Content Delivery Networks (CDNs) represent a geographically distributed network of proxy servers and their data centers, strategically positioned to provide high availability and high performance delivery of internet content to end-users. (CDNs) distribute images from geographically closer servers to users, reducing latency and improving LCP. Services like Cloudflare or BunnyCDN are SMB-friendly options.

Tools ● TinyPNG, ImageOptim, WebP Converter, Cloudflare, BunnyCDN.

Enable Browser Caching

Impact on CWV ● Improves LCP and subsequent page load times by storing static assets (images, CSS, JavaScript) in users’ browsers. Reduces server load and data transfer.

Actionable Steps:

1. Set Proper Cache Headers ● Configure your server to send appropriate cache headers (Cache-Control, Expires) for static assets. This instructs browsers to cache these assets for a specified duration.
2. Leverage Browser Caching ● Utilize browser caching by setting long cache durations for static, infrequently changed assets. Shorter durations for dynamic content.
3. Test Cache Implementation ● Use online tools (like GTmetrix or WebPageTest) to verify that browser caching is correctly implemented and effective.

Tools ● Server configuration settings (e.g., .htaccess for Apache, Nginx configuration), GTmetrix, WebPageTest.

Defer Loading Non-Critical Javascript

Impact on CWV ● Reduces First Input Delay (FID) and improves LCP by minimizing main-thread work during initial page load. Prevents JavaScript from blocking rendering.

Actionable Steps:

1. Identify Non-Critical JavaScript ● Determine JavaScript code that is not essential for initial page rendering or user interaction (e.g., analytics scripts, social media widgets below the fold).
2. Defer Loading ● Use the defer attribute in script tags for non-critical JavaScript. This allows the browser to continue parsing HTML and rendering the page while the script downloads in the background.
3. Asynchronous Loading ● For scripts that can be loaded without blocking page rendering, use the async attribute.
4. Code Splitting ● For larger JavaScript applications, implement code splitting to load only necessary JavaScript initially, deferring the rest.

Tools ● Webpack (for code splitting), browser developer tools (for identifying blocking JavaScript).

Optimize Text Compression

Impact on CWV ● Improves LCP by reducing the size of HTML, CSS, and JavaScript files transferred over the network. Speeds up resource download times.

Actionable Steps:

1. Enable Gzip or Brotli Compression ● Configure your server to use Gzip or Brotli compression for text-based resources. Brotli offers better compression ratios than Gzip but may require more server resources.
2. Verify Compression ● Use online tools (like Check Gzip Compression) or browser developer tools to ensure compression is enabled and working effectively.

Tools ● Server configuration settings (e.g., .htaccess, Nginx configuration), Check Gzip Compression.

Preload Critical Resources

Impact on CWV ● Improves LCP by prioritizing the loading of critical resources (e.g., hero images, key CSS files, fonts) that are essential for rendering the above-the-fold content.

Actionable Steps:

1. Identify Critical Resources ● Determine resources that are essential for initial page rendering, particularly the LCP element.
2. Use ● Add tags in the of your HTML to instruct the browser to prioritize downloading these critical resources early. Specify as attribute (e.g., image, style, font).
3. Preload LCP Image ● Specifically preload the image that is likely to be the LCP element to expedite its loading.

Tools ● Browser developer tools (for identifying critical resources), HTML editor.

Advanced Image Optimization Strategies

While basic image compression is a quick win, advanced image optimization for LCP involves a more nuanced approach:

1. Modern Image Formats (WebP) ● Consistently use WebP format for images. WebP offers superior compression and quality compared to JPEG and PNG. Implement content negotiation to serve WebP to browsers that support it and fall back to JPEG/PNG for older browsers. Tools like Cloudinary or Imgix can automate WebP conversion and delivery.
2. Adaptive Image Serving ● Implement responsive images using element or srcset attribute in tags. Serve different image sizes based on device screen size and resolution. This ensures users on mobile devices don’t download unnecessarily large images.
3. Automated Image Optimization Pipelines ● Integrate image optimization into your development workflow. Use build tools or CDNs that automatically compress, resize, and convert images during deployment. Services like ImageEngine or Fastly Image Optimizer provide automated, real-time image optimization.
4. Client Hints for Image Optimization ● Leverage Client Hints (Save-Data, Viewport-Width, DPR) to allow the browser to communicate device capabilities to the server. The server can then dynamically optimize and serve images tailored to the user’s device and network conditions.
5. Critical Image Preloading ● Preload the LCP image using . Ensure the fetchpriority="high" attribute is used for even greater prioritization. Verify preload implementation with Lighthouse to ensure it’s effective and not causing resource contention.

Leveraging Content Delivery Networks (Cdns)

CDNs are crucial for LCP optimization, especially for SMBs with a geographically diverse audience:

1. Global CDN Implementation ● Choose a CDN with a global network of Points of Presence (PoPs). CDNs store cached copies of your website’s static assets (images, CSS, JavaScript) closer to users, reducing latency and improving LCP. Services like Cloudflare, Akamai, Fastly, and Amazon CloudFront are popular options.
2. Origin Server Optimization with CDN ● Ensure your origin server is properly configured to work efficiently with the CDN. Optimize origin server response times (TTFB) as CDN performance is dependent on origin server speed.
3. CDN Caching Strategies ● Configure CDN caching rules effectively. Cache static assets aggressively with long cache durations. Use cache invalidation strategically when content updates. Optimize cache headers (Cache-Control, Expires) for CDN and browser caching.
4. Dynamic Content Acceleration (DCA) ● Some CDNs offer Dynamic Content Meaning ● Dynamic content, for SMBs, represents website and application material that adapts in real-time based on user data, behavior, or preferences, enhancing customer engagement. Acceleration features to optimize delivery of dynamic content, not just static assets. Explore DCA options if your LCP element is dynamically generated.
5. Http/3 and CDN ● Utilize CDNs that support HTTP/3. HTTP/3 offers performance improvements over HTTP/2, especially in lossy network conditions, potentially benefiting LCP.

Server Response Time (Ttfb) Optimization

Optimizing Time to First Byte (TTFB) is critical for LCP as it represents the initial server response time. Slow TTFB directly delays LCP. SMBs should focus on these TTFB optimization strategies:

1. Optimize Hosting Infrastructure ● Choose a hosting provider with fast servers and low latency. Consider upgrading to a Virtual Private Server (VPS) or dedicated server if shared hosting is causing slow TTFB. Cloud hosting platforms like AWS, Google Cloud, and Azure offer scalable and high-performance hosting options.
2. Database Optimization ● If your website is database-driven, optimize database queries. Slow database queries are a common cause of slow TTFB. Implement database indexing, query caching, and optimize database schema. Use database performance monitoring tools to identify slow queries.
3. Server-Side Caching ● Implement server-side caching mechanisms. Cache frequently accessed data in memory (e.g., using Memcached or Redis) to reduce database load and improve TTFB. Use content caching at the server level to serve pre-rendered pages.
4. Efficient Server-Side Code ● Optimize server-side code (e.g., PHP, Python, Node.js). Profile code to identify performance bottlenecks. Use efficient algorithms and data structures. Minimize blocking operations in server-side code.
5. Minimize Redirects ● Reduce the number of redirects, especially HTTP redirects. Redirects increase latency and TTFB. Implement HTTPS redirects properly and avoid unnecessary redirect chains.

Resource Prioritization and Loading

Effective resource prioritization ensures that critical resources for LCP are loaded early:

1. Eliminate Render-Blocking Resources ● Minimize or eliminate render-blocking CSS and JavaScript. Defer non-critical CSS and JavaScript. Inline critical CSS for above-the-fold content. Use code splitting to load only necessary JavaScript initially.
2. Prioritize Critical Css ● Identify and inline critical CSS required for rendering above-the-fold content. This allows the browser to start rendering content faster, improving LCP. Use tools like CriticalCSS to automate critical CSS extraction.
3. Font Optimization ● Optimize web fonts. Use font-display ● swap to prevent text from being invisible during font loading. Preload web fonts using with as="font" and correct crossorigin attribute. Consider using system fonts for better performance if appropriate.
4. Connection Preconnect and Dns-Prefetch ● Use and to establish early connections to critical third-party origins. This reduces connection latency for resources hosted on external domains, benefiting LCP.
5. Preload LCP Element ● As mentioned earlier, preload the LCP element itself, whether it’s an image, video, or text block. Ensure the preload is effective and not causing resource contention.

Reduce Javascript Execution Time

Excessive JavaScript execution is a primary cause of high FID. Optimizing JavaScript is paramount:

1. Identify Long-Running Javascript Tasks ● Use Chrome DevTools Performance panel to profile JavaScript execution. Identify long-running tasks that block the main thread and contribute to FID. Focus on optimizing these tasks first.
2. Optimize Javascript Code Efficiency ● Review JavaScript code for inefficiencies. Refactor code to use more efficient algorithms and data structures. Minimize DOM manipulations and reflows, which are computationally expensive.
3. Debounce and Throttle Event Handlers ● For event handlers like scroll, resize, and input, use debouncing or throttling to limit the frequency of execution. This prevents excessive JavaScript execution and improves responsiveness.
4. Web Workers for Background Tasks ● Offload non-UI-blocking JavaScript tasks to Web Workers. Web Workers run in separate threads, freeing up the main thread for UI interactions and improving FID. Use Web Workers for tasks like data processing, analytics, or background synchronization.
5. Virtualization for Long Lists ● For pages with long lists or tables, implement virtualization (also known as windowing). Virtualization renders only the visible portion of the list, significantly reducing DOM size and JavaScript execution time. Libraries like react-window or vue-virtual-scroller can simplify virtualization implementation.

Optimize Third-Party Scripts

Third-party scripts (ads, analytics, social media widgets) can significantly impact FID. Effective management is crucial:

1. Audit Third-Party Scripts ● Regularly audit third-party scripts. Identify scripts that are unnecessary or have a significant performance impact. Remove or replace poorly performing scripts.
2. Defer Loading Third-Party Scripts ● Defer loading non-critical third-party scripts. Load them after the main content and critical JavaScript have loaded. Use async or defer attributes in script tags.
3. Lazy-Load Third-Party Iframes ● Lazy-load third-party iframes (e.g., embedded videos, social media embeds). Load iframes only when they are about to enter the viewport. Use the loading="lazy" attribute for iframes.
4. Proxy Third-Party Content ● Consider proxying third-party content through your own domain. This can improve control over caching and reduce the impact of third-party server latency. CDNs can be used for proxying and caching third-party content.
5. Static Rendering for Embeds ● Where possible, replace dynamic third-party embeds with static renderings. For example, replace a live social media feed with a static screenshot that links to the social media profile.

Code Splitting for Reduced Initial Load

Code splitting is a powerful technique to reduce initial JavaScript load and improve FID:

1. Component-Based Code Splitting ● In component-based frameworks (React, Vue, Angular), split your application code into smaller bundles based on components or routes. Load only the code necessary for the initial view. Use dynamic imports to load components on demand.
2. Route-Based Code Splitting ● Split code based on website routes or pages. Load JavaScript for a specific route only when the user navigates to that route. This reduces the initial JavaScript bundle size and improves initial page load and FID.
3. Feature-Based Code Splitting ● Split code based on features or functionalities. Load code for specific features only when they are needed. For example, load code for a chat widget only when the user initiates chat.
4. Webpack and Rollup for Code Splitting ● Use module bundlers like Webpack or Rollup to implement code splitting. These tools offer built-in support for dynamic imports and code splitting configurations.
5. Analyze Bundle Size ● Use bundle analyzers (e.g., Webpack Bundle Analyzer, Rollup Visualizer) to visualize JavaScript bundles and identify large bundles that can be split. Regularly monitor bundle sizes to prevent regressions.

Optimize Input Handling

Efficient input handling directly impacts FID. Ensure input handlers are optimized and non-blocking:

1. Optimize Event Listener Performance ● Ensure event listeners (e.g., click, keypress, touch) are efficient and non-blocking. Avoid long-running tasks within event listeners.
2. Use RequestAnimationFrame for Animations ● For animations triggered by user input, use requestAnimationFrame. requestAnimationFrame schedules animations to run before the next browser repaint, ensuring smooth animations and preventing blocking of input handling.
3. Avoid Synchronous Operations in Input Handlers ● Avoid synchronous operations (e.g., synchronous XHR requests, heavy computations) in input handlers. Use asynchronous operations (e.g., fetch API, Promises) for non-UI-blocking tasks.
4. Optimize Form Interactions ● Optimize form interactions to be responsive. Use client-side validation to provide immediate feedback to users without server round trips. Optimize form submission process to be non-blocking.
5. Smooth Scrolling Implementation ● Implement smooth scrolling efficiently. Avoid JavaScript-based smooth scrolling implementations that can be janky and impact FID. Use CSS-based smooth scrolling (scroll-behavior ● smooth) where possible.

• Incremental Improvements ● Focusing on specific CWV metrics (LCP in this case) and implementing targeted optimizations yields tangible results.

Reserve Space for Images and Videos

A primary cause of CLS is images and videos loading without predefined dimensions. Browsers initially render the page without knowing the dimensions, then reflow the content when the media loads. To prevent this:

1. Specify Width and Height Attributes ● Always include width and height attributes on and tags. Browsers use these attributes to reserve the correct space during initial layout. Ensure these attributes reflect the intrinsic aspect ratio of the media.
2. Css Aspect Ratio Boxes ● Use CSS aspect ratio boxes to maintain aspect ratio responsively. Apply CSS properties like aspect-ratio or padding-top/padding-bottom percentage hacks to create containers with fixed aspect ratios for images and videos. This ensures consistent space reservation across different screen sizes.
3. Sizing Attributes for Responsive Images ● When using responsive images with srcset and sizes attributes, ensure the browser has enough information to calculate the correct space reservation for different viewport sizes. sizes attribute helps the browser determine the appropriate image size and aspect ratio.
4. Avoid Inserting Content Above Existing Content ● Be cautious when inserting new content (images, ads, banners) above existing content. This is a common cause of CLS. If insertion is necessary, reserve space for the inserted content from the start.
5. Test with Slow Connections ● Test your website on slow network connections (using browser throttling) to identify layout shifts that might not be apparent on fast connections. Slow connections exacerbate CLS issues by delaying resource loading.

Optimize Ads and Embeds for Stability

Ads and embeds (iframes) are frequent contributors to CLS due to their dynamic and often unpredictable nature. Strategies to mitigate CLS from ads and embeds include:

1. Reserve Space for Ads ● Statically reserve space for ads using placeholders. Define fixed dimensions for ad containers, even if the actual ad creative size varies. This prevents layout shifts when ads load. If ad sizes are variable, reserve space for the largest possible ad size.
2. Minimize Top-Of-Viewport Ads ● Avoid placing ads at the top of the viewport if possible. Top-of-viewport ads are more likely to cause significant CLS. Place ads in less visually disruptive locations.
3. Use Placeholder Content for Embeds ● For embeds (e.g., YouTube videos, social media embeds), use placeholder content with predefined dimensions until the actual embed loads. This prevents layout shifts when iframes load and render.
4. Lazy-Load Embeds ● Lazy-load embeds below the fold. This defers loading embeds until they are about to enter the viewport, reducing initial CLS and improving initial page load performance.
5. Consider Static Ad Rendering ● Explore options for static ad rendering or server-side ad insertion. This can provide more control over ad loading and reduce CLS compared to client-side ad loading.

Font Optimization and Cls

Web fonts can cause CLS if the fallback font (system font) has different metrics than the web font. This is known as Flash of Unstyled Text (FOUT) or Flash of Invisible Text (FOIT). Optimize fonts to minimize font-related CLS:

1. Use Font-Display ● Swap ● Use font-display ● swap in @font-face declarations. swap instructs the browser to use the fallback font immediately and swap to the web font once it’s loaded. This prevents FOIT and minimizes FOUT-related CLS.
2. Preload Web Fonts ● Preload critical web fonts using with as="font" and correct crossorigin attribute. Preloading prioritizes font loading and reduces the time window for FOUT.
3. Choose Fonts with Similar Metrics ● Select web fonts that have similar font metrics (line height, character widths) to system fallback fonts. This minimizes visual differences during font swap and reduces CLS.
4. Optimize Font File Sizes ● Optimize web font file sizes. Use font formats like WOFF2 for better compression. Subset font files to include only necessary characters. Remove unused font variations.
5. System Fonts as Fallbacks ● Consider using system fonts as fallbacks or even primary fonts if appropriate for your design. System fonts load instantly and eliminate font-related CLS.

Avoid Layout-Shifting Animations

Animations can inadvertently cause CLS if they trigger layout reflows. Avoid animations that modify layout properties:

1. Use Transform and Opacity for Animations ● Prefer using CSS transform and opacity properties for animations instead of properties that trigger layout reflows (e.g., width, height, top, left). transform and opacity are composited properties and do not cause layout shifts.
2. Will-Change Property ● Use the CSS will-change property to inform the browser about upcoming animations on an element. This allows the browser to optimize rendering and potentially reduce CLS for animations.
3. Avoid Non-Composited Animations ● Be aware of animations that are not composited. Non-composited animations are more likely to cause layout shifts. Ensure animations are hardware-accelerated and composited by the browser.
4. Test Animations for Cls ● Test animations thoroughly to ensure they do not introduce unexpected layout shifts. Use browser performance profiling tools to analyze animation performance and CLS impact.
5. Transition Property Considerations ● When using CSS transition property, be mindful of properties being transitioned. Avoid transitioning layout properties if possible. Prefer transitioning transform and opacity.

Visual Stability Testing and Monitoring

Proactive CLS prevention requires visual stability testing and continuous monitoring:

1. Manual Visual Inspection ● Manually inspect your website on different devices and browsers, especially during development and after updates. Look for unexpected layout shifts during page load and user interactions.
2. Automated Visual Regression Testing ● Implement automated visual regression testing. Tools like BackstopJS, Percy, or Chromatic can capture screenshots of your website and detect visual regressions, including layout shifts, with each code change.
