Frequently Asked Questions
INP is a Core Web Vital that replaced FID in 2024. It measures the responsiveness of every interaction on your page. In, Google uses INP as a primary measure of user "Interactivity Health." A "Good" score is under 200ms, while under 150ms is ideal for high-ranking sites.
The most common fixes for Largest Contentful Paint (LCP) include: 1. Optimizing and compressing hero images to WebP/AVIF. 2. Removing render-blocking JavaScript. 3. Using a high-performance Content Delivery Network (CDN). 4. Ensuring your server has a low TTFB (Time to First Byte).
Scores fluctuate because of "Network Variability" and "Server Load." If your server is busy or the user's network is slow, metrics like LCP will suffer. This is why Google looks at the 75th percentile of real-user data (Field Data) rather than just a single test (Lab Data).
Yes, but it requires extreme optimization. Often, the trade-off for a perfect 100 is removing helpful features like analytics or chat widgets. Most professionals aim for 90+ while ensuring they "Pass" all three Core Web Vitals thresholds.
Yes. Since 2021, Core Web Vitals have been an official ranking factor. In, this signal has been strengthened. While high-quality content is still king, a slow site will always lose to a fast site with similar content quality.
The primary culprits of CLS are images without dimensions, ads, embeds, and iframes without reserved space, and dynamically injected content. Using CSS "aspect-ratio" properties is the most effective way to fix this.
Time to First Byte (TTFB) is the foundation of all other speed metrics. If your TTFB is slow (>600ms), your LCP and FCP will also be slow. It signals to Google that your infrastructure is outdated or under-resourced.
Lab Data is a simulated test in a controlled environment (like this analyzer). Field Data (CrUX) is collected from real Chrome users over the last 28 days. Google uses Field Data for its actual ranking decisions, but Lab Data is vital for debugging.
Mobile first. Google uses the mobile version of your site for indexing and ranking. A fast desktop site will not save you from ranking demotions if your mobile experience is slow or laggy.
To reduce JS execution: 1. Code-split your bundles. 2. Minify and compress scripts. 3. Remove unused third-party libraries. 4. Defer non-critical scripts until after the user has engaged with the page.
