What it checks

What this free website SEO audit tool checks on every URL

Reading the report

What to fix first, and what can wait

A crawl of a normal site returns more findings than anybody has time for, and they are not equally important. This is the order we work in.

1. Anything that stops a page being indexed

A noindex tag left on after a redesign, or a canonical pointing at a different URL, removes a page from Google entirely. No amount of content work matters while either is in place. These are rare and they are catastrophic, so they get checked first. A page that canonicalises to another page is telling Google to index that other one instead.

2. Broken status codes

404s that are linked from your own pages waste the crawl budget you have and lose the visitors who follow them. Redirect chains, where one URL points to a second which points to a third, leak a little of the value each hop. Fix them to point directly at the destination.

3. Duplicate titles

Two pages with the same title are usually two pages competing for the same search. Google picks one, inconsistently, and both rank worse than either would alone. This is keyword cannibalisation, and it is the most common serious problem we find on sites that have been added to for a few years. The fix is to decide which page owns the query and change the other, or merge them.

4. Missing or over-length titles and descriptions

A missing title means Google writes one for you. Past roughly 70 characters for a title and 160 for a description, the rest is cut off, so anything you needed the reader to see should be at the front. These are quick wins and they change click-through rate rather than ranking.

5. Headings

One H1 per page, describing what the page is actually for. Multiple H1s are not a penalty, but they usually mean nobody decided what the page was about. H2s should read as an outline of the page if you read only them.

6. Images without alt text

Alt text is first an accessibility requirement and second an SEO one. Describe what the image shows to somebody who cannot see it. Decorative images should have an empty alt attribute, not a keyword.

7. Structured data

Schema does not make a page rank higher on its own. It makes a page eligible for the richer results that get clicked more. Mark up what is genuinely on the page, and nothing that is not: a rating you have marked up but not shown is the single most common reason a site gets a structured-data manual action.

Honest limits

What this tool does not do

It runs in your browser, which is what makes it instant and free, and also what bounds it. It reads the HTML a page returns. It does not run your JavaScript, so a site that renders its content client-side will look emptier here than it does to a modern crawler. It does not measure Core Web Vitals, check your backlinks, or tell you what you rank for — Search Console and a rank tracker do those, and both are better at it than any one-page tool.

Some sites will not be readable at all. A server behind a strict firewall, or one that blocks cross-origin requests, will return nothing here even though it is perfectly healthy. That is a limit of the browser, not a verdict on the site.

What it is good for is the technical layer: the findings above, across every URL on a domain, exported to a spreadsheet in a couple of minutes. That is usually enough to know whether a site has a structural problem or a content one, which is the question worth answering before anybody spends money.

If you would rather understand the findings than act on them straight away, the free SEO course explains each one from the beginning. If the report says the problem is structural and you want it fixed, that is our SEO services work, and you can send us the export rather than describing it.
