Guide

How to run a free website SEO check

A useful website checker answers whether the page is technically ready: title, meta, a single H1, canonical, Open Graph, and robots. That is this tool. For a dedicated Ahrefs DR checker, use the single-domain lookup.

The score is a checklist, not a Google ranking. Fix missing titles, multiple H1s, and noindex before you chase more links.

Compare two homepages with SEO Compare when you need a side-by-side matrix.

Explore more on free ScrollLaunch tools, browse DR-ranked directories, or launch with a dofollow backlink.

Questions

SEO Checker FAQ

What does this website SEO checker cover?

A 0–100 on-page readiness score and a pass/fail checklist. Host Domain Rating is included as a bonus. It is not a Google ranking prediction.

I only want an Ahrefs DR checker - is this the right tool?

No. Use the free Ahrefs DR checker for a single domain, or the bulk domain rating checker for a list. This page is the on-page audit.

How is this different from SEO Compare?

This audits one URL. SEO Compare puts two homepages side by side.

Does it crawl the whole site?

No - it fetches the URL you paste (plus robots.txt for a Sitemap: line). Use the sitemap suite for site-wide URL lists.

Where does Domain Rating come from?

Ahrefs' free public Domain Rating API. Credit results as Domain Rating by Ahrefs. For a dedicated lookup, use the Ahrefs DR checker.
