Free Website SEO Audit

What is an SEO audit?

An SEO audit checks a web page against the basics that search engines look for before they decide how to rank it. It does not guess at rankings — it looks at concrete things on the page itself: whether the title is the right length, whether images have alt text, whether the page works on a phone, and so on.

This audit covers the on-page basics. It will not tell you how many backlinks a page has or where it ranks — those need paid data. But the basics are the part you can fix yourself, for free, today.

What is an SEO audit for, and who uses it?

An audit is for anyone responsible for a website: site owners checking their own pages, bloggers and writers reviewing a new post before publishing, freelancers and agencies reporting to a client, and developers verifying a page after a redesign or a platform move.

It is also the fastest way to compare a page against a competitor’s. Audit both pages, put the checklists side by side, and the gaps — a missing description, no H1, images without alt text — tell you exactly where to start.

Benefits of running an SEO audit

A regular audit pays for itself in four ways:

• Finds silent problems — a missing title or a page blocked from crawling can cost traffic for months without anyone noticing.
• Gives you an order to work in — failed checks first, then warnings, so you fix what matters most instead of guessing.
• Makes progress measurable — re-run the audit after each round of fixes and the score shows whether the work actually helped.
• Protects new pages — checking a page before it goes live is far cheaper than discovering its problems after it has been indexed.

What the audit checks

Sixteen checks, grouped into five areas:

• Titles & descriptions — page title length (30–60 characters), meta description length (120–160 characters) and the targeted keyword, if you enter one.
• Headings & structure — exactly one H1, and H2 headings that organise the content.
• Images & links — alt text on every image, and links with real anchor text.
• Mobile & technical — viewport tag, language attribute, character encoding, canonical tag, robots meta tag and favicon.
• Social & structured data — Open Graph tags, Twitter card and JSON-LD structured data.

How to read your score

The score is weighted: title, description, H1 and mobile viewport count double, because they matter most. A “warn” counts half. So a page can score well even with a few warnings, but a failed title or missing viewport will drag it down. Structured data is shown as a note and does not affect the score — Google no longer shows FAQ rich results, so FAQ markup earns no points.

Use the score as a starting point, not a verdict. Fix the failed checks first, then the warnings, then re-run the audit. A page that scores 90+ has its technical basics in good shape — the next step is better content, not a higher score.

Best practices — and common mistakes

A few habits make audits far more useful:

• Audit before publishing, not after — a new page is cheapest to fix before Google indexes it.
• Fix one issue at a time and re-run the audit, so you know which change moved the score.
• Do not chase a perfect 100 — a page can score 90+ and still need better content; a page can score 100 on technicals and still not rank.
• Do not audit once and forget it — redesigns, new templates and plugin updates quietly break titles, tags and mobile layouts.
• Do not treat the score as a Google metric — it is this tool’s measure of the on-page basics, not a ranking factor.
