FAQ
How does this website speed checker work?
This is a self-assessment tool. You answer 15 questions about your website setup across three categories: Loading Speed, Core Web Vitals, and Best Practices. Based on your answers, you get a score out of 100 with specific recommendations. For actual performance metrics, we link you to Google PageSpeed Insights to test your live site.
What are Core Web Vitals and why do they matter?
Core Web Vitals are three metrics Google uses to measure user experience: LCP (Largest Contentful Paint) measures loading speed, INP (Interaction to Next Paint) measures interactivity, and CLS (Cumulative Layout Shift) measures visual stability. Google uses these as ranking factors, meaning poor Core Web Vitals can hurt your search engine rankings.
What is a good website speed score?
A score of 90-100 is excellent, meaning your site follows nearly all performance best practices. A score of 50-89 means there is room for improvement. Below 50 indicates significant performance issues that are likely hurting user experience and SEO. Most sites score between 50-80 on their first assessment.
How can I improve my website speed quickly?
The fastest wins are: compress and properly size images (often saves 50%+ page weight), enable Gzip/Brotli compression on your server, use a CDN like Cloudflare (free tier available), and defer non-critical JavaScript. These four changes alone can improve load times by 2-5 seconds on most sites.
Does website speed affect SEO rankings?
Yes. Google has confirmed that page speed is a ranking factor, especially on mobile. Core Web Vitals (LCP, INP, CLS) are part of the page experience signals that directly impact search rankings. Slow sites also have higher bounce rates: 53% of mobile users abandon sites that take over 3 seconds to load.
