How the SEO audit works
We fetch your page once
Our server asks your website for the address you gave, follows up to three redirects and reads the HTML that comes back, without running JavaScript.
We read the on-page basics
Title, meta description, canonical link, headings, image alt text, JSON-LD schema, robots rules, HTTPS, viewport and language. Each one is marked looks good, worth a look or needs fixing.
Google tests the speed
At the same time we ask Google PageSpeed Insights for a mobile performance score. It is shown on its own and doesn’t change the on-page score.
You get a plain-English report
A score out of 100 for the on-page checks, with a note on every item and the title, description, heading outline and schema types we found.
What the score is
- A quick on-page check of one page, out of 100.
- Your share of the marks across eleven checks, with the four most visible ones counting double.
- A useful list of things to tidy up before, or alongside, a proper review.
What it isn’t
- Not a full SEO audit: it doesn’t crawl the rest of your site or look at links, content quality, keywords or Search Console.
- Not a prediction of where you’ll rank, and not a comparison with other websites.
- Not able to see content your site adds with JavaScript after loading.
Questions
What does this SEO audit tool check?
It reads one page and checks eleven basics: the page title, meta description, canonical link, main heading, heading order, image alt text, JSON-LD schema, whether search engines are allowed to index the page, HTTPS, the mobile viewport tag and the page language. It also asks Google PageSpeed Insights for a mobile performance score.
Is this a full SEO audit?
No. It is a quick on-page check of a single address. A full audit also looks at every page on the site, internal links, content quality, the keywords you want to be found for, local listings, backlinks and your Search Console data, which a free tool can’t see.
How is the website grader score worked out?
Each check earns full marks for “looks good”, half marks for “worth a look” and nothing for “needs fixing”. Title, meta description, main heading and indexing count double because they matter most for how a page shows in search. The score is your share of the available marks, out of 100. It isn’t a ranking prediction and it doesn’t compare you with other websites.
Why is my title or description flagged when it looks fine to me?
The tool uses guide ranges of 30 to 60 characters for titles and 70 to 160 for descriptions. Google doesn’t publish a fixed limit and cuts long snippets by width, so a “worth a look” here is a prompt to check, not a rule you’ve broken.
Why does it say something is missing that I can see on my page?
The tool reads the HTML your server sends, the way a simple crawler would, without running JavaScript. If your site builds its title, headings or images with JavaScript after the page loads, they won’t appear here. Search engines can usually run JavaScript, but content in the first HTML is the safest bet.
Why is the speed score sometimes unavailable?
The speed score comes from Google PageSpeed Insights, which loads your page in a test browser. If Google takes longer than about 40 seconds or can’t load the page, the report still shows every on-page check and says the speed score is unavailable. Try again later for a fresh speed test.
What happens to the address I enter?
Our server fetches that one page to read it, and sends the address to Google PageSpeed Insights for the speed test. The tool doesn’t save the address or the report, and it can only check public websites, not local or private network addresses.
