Why Speed is the #1 Ranking Factor
In the modern web, speed is money. Google has explicitly stated that page speed is a ranking factor for mobile searches. A slow website frustrates users, increases bounce rates, and directly hurts your SEO. The **NexRank Page Speed Test** uses the same technology (Lighthouse) that Google uses to evaluate your site, giving you actionable data to improve your performance.
Understanding Core Web Vitals
- Largest Contentful Paint (LCP) Measures loading performance. This marks the point when the main content of the page has likely loaded. A good LCP score is **2.5 seconds or less**.
- First Input Delay (FID) / TBT Measures interactivity. How long does it take for the browser to respond when a user clicks a button? A good score is **100 milliseconds or less**.
- Cumulative Layout Shift (CLS) Measures visual stability. Does content jump around while loading? A good CLS score is **0.1 or less**.
How to Improve Your Score
Once you run the test, focus on these common optimizations:
- Optimize Images: Use our WebP Converter to reduce file sizes.
- Minify Code: Use our JSON Minifier (and similar tools for CSS/JS) to strip whitespace.
- Enable Caching: Configure your server to cache static assets so returning visitors load your site instantly.
