Free SEO audit for Google and AI search
See whether Google, ChatGPT, Claude and Perplexity can find, read and quote your website. A score out of 100 and a plain fix for everything that is missing.
What it checks
- AI crawlers
- Whether robots.txt lets in Google, Bing, ChatGPT, Claude, Perplexity, Gemini and Apple, and whether your sitemap is there.
- AI files
- Whether you have an llms.txt, the short summary of your site written for AI assistants.
- Structured data
- The JSON-LD that tells search engines who you are and what the page offers: Organization, WebSite, FAQ, Product, Article.
- Search basics
- The page loads, may be listed, and has a good title, description, one H1, a canonical address and a mobile viewport.
- Content
- The work behind the site: enough real text, how many pages it has, whether it publishes new posts, links between pages, answers to common questions, no leftover template text.
- Trust
- HTTPS, one version of the site (www or not), an About page and contact, an updated date and security headers.
- Speed and icons
- How fast the server answers, the icon Google shows next to your result, and the preview card for shared links.
Questions
What does this SEO audit check?
30 things in seven areas that decide whether Google and AI assistants can find, read and quote your site: crawler access, llms.txt, structured data, titles and headings, how much content you have and how often you publish, HTTPS and trust signals, speed and icons. Each one gets a plain fix.
Is it really free?
Yes. No sign-up and no card. You can run a few audits every few minutes; the limit only stops robots from using it.
What is AI search, and why does my site need it?
More people now ask ChatGPT, Claude, Perplexity or Google's AI answers instead of clicking through search results. Those assistants recommend and link to sites they are allowed to read and can understand. The audit checks both.
How is the score worked out?
Each check is worth points. The things that take real work count most: content, pages, regular posts and structured data. Things most hosts give you for free, like HTTPS, count less. The score is the share of points your page earns, out of 100: 90 and up is excellent, 70 good, 50 needs work. A page that blocks Google or is set to noindex scores 30 at most.
Does it check my whole site?
It checks the address you give it in depth, plus the site-wide files every crawler reads: robots.txt, the sitemap, llms.txt and the favicon. Run it on your home page first, then on your most important pages.
Do you use AI to score my site?
No. The audit is plain rules, so the same page gets the same score every time and you can see exactly why.
Then give them something to quote
A clean site gets read. What gets quoted is good, regular content. FreeBlogWriter writes researched SEO posts in your voice, with FAQ and schema already in place. Your first 4 posts are free, no card.
