What are Core Web Vitals?

Core Web Vitals are a set of specific metrics used by Google to measure the user experience of a webpage, focusing on loading speed, responsiveness, and visual stability. Tools available: `your_tool_name`.

How is the composite score calculated?

The composite score is a weighted average of your LCP, INP, and CLS statuses. Each metric is assigned a grade: Good (100), Needs Improvement (50), or Poor (0).

Does this tool affect my SEO?

While the tool itself doesn't change your site, it provides an estimate of how your current performance metrics might impact your search engine visibility.
