How the SEO audit tool calculates your score
Many tools give you a number without explaining it. Ours is a weighted average of five scores, so you can see exactly what moved it.
SEO and on-page tests count for 60% of the overall score, because they relate most directly to search. Performance counts for 20%, while accessibility and best practices count for 10% each.
If Google can't test a page, we leave that score out and base the result on what we could measure. The report tells you when that happens.
Know the limits
Free SEO audit tool or a full manual audit?
An automated SEO audit tool is a fast first step. It can't replace a person reviewing your whole site and market, so here's when each makes sense.

|---|---|---|
| Coverage | One page at a time, on mobile | Your whole site and key templates |
| Time | About 30 seconds | Agreed with you, based on site size |

| Competitors and keywords | Not included | Can be researched for your market |
| Best for | Quick checks and spotting obvious problems | Planning serious SEO work |

When to use it
Good times to run an SEO audit
Before a redesign
Record your starting scores, so you can tell whether the new site has improved things.
After launch
Catch a forgotten noindex setting, missing titles or broken basics. Our web development team can help you fix them.
For new client work
Get a quick picture of a prospect's page before a first call, then confirm the findings yourself.
When traffic drops
Rule out technical causes on your key pages before you look at content and competitors.
FAQ
SEO audit tool questions, answered
What data does the SEO audit tool use?
It uses the Google PageSpeed Insights service, which runs Lighthouse on a mobile device, plus our own tests of your page's HTML, robots.txt and sitemap.
Does it test the desktop version of my site?
No. It tests mobile only, because Google mainly uses the mobile version of a page for indexing and ranking.
Does it check backlinks or keyword rankings?
No. It looks at the page itself. Backlinks, rankings and competitor research are part of a full SEO service.
Can I audit a competitor or client website?
Yes. The tool works on any public web page, and it only reads what's publicly available. It can't test pages behind a login.
Why might the on-page checks be skipped?
Some servers block automated visitors. If ours is blocked, the report says so and shows the results it could still get. It's also worth checking that the block doesn't affect search engines.
How many audits can I run?
Up to about 10 an hour from one connection, which keeps the service available for everyone. Results for a page are saved for up to 6 hours, so re-testing right after a fix may show the earlier result.
