Frequently asked questions

What does the tool check?

21 on-page SEO rules across three groups. Content: title tag, meta description, H1, heading outline, word count, image alt text and internal links. Technical: HTTPS, lang, charset, viewport, canonical, robots meta, robots.txt, sitemap, structured data, page weight and response time. Social: Open Graph, Twitter card and favicon.

How is the score calculated?

Every rule carries a weight reflecting how much it affects SEO. A passing rule earns its full weight, a warning earns half, a failure earns nothing. The total is normalised to 100 and mapped to a letter: A from 90, B from 80, C from 70, D from 50, anything lower is F.

Do I need an account, and is it free?

It is free and needs no account. Paste a URL, press audit, read the report — no trial limit and no payment details.

Why does this score differ from other SEO tools?

Every tool picks its own rules and weights, so scores are not directly comparable. This one reads exactly the HTML your server returns and does not execute JavaScript, so a page that renders its content entirely on the client can score lower than it deserves.

Does it crawl my whole website?

No. Each run analyses the single URL you enter. To cover more pages, audit them one at a time; the most recent runs are listed on the History page.

Is my data stored?

The URL, score, grade, status code, response time, timestamp and the full report are stored so the History page can list them. The report includes short extracts from the page such as the title tag, meta description and H1 — the full HTML is not kept. Note that the History page is public: anyone can see which URLs have been audited, so avoid auditing URLs that are themselves confidential.
