## How it works

The Core Web Vitals Calculator runs directly against a live URL or your own pasted content — no signup, no install. Results come back in seconds as a prioritized, plain-English list rather than a raw score, so you know exactly what to fix first and why it matters. It's a focused, single-purpose check, built to answer this one question quickly rather than replace a full technical audit.

1. Paste in your URL, text, or data — no signup required.
2. The tool runs its analysis and returns results in seconds.
3. Review the flagged issues, ranked by severity, with a plain-English explanation of each.
4. Fix the highest-priority items first, then re-run to confirm.

**Why it matters:** Technical SEO is the foundation everything else sits on: if a page can't be crawled efficiently, rendered correctly, or loaded fast enough, no amount of content or backlinks fixes that. Most technical issues are invisible until you specifically look for them.

This is a free, interactive, browser-based tool — no signup required. It runs client-side JavaScript, so this Markdown page describes what it does; [use the live tool](https://iliassami.com/tools/core-web-vitals) to actually run it.
