Example Results

I ran ScriptByAI.com through Free AI SEO Auditor to see how a real content site would score.

My homepage received a 79/100 AI visibility score, with 16 checks passed, 6 partial checks, 4 failed checks, and 6 items marked as not applicable. The result showed that the page had a strong technical base, but still needed clearer answer-style content, stronger entity signals, and more visible trust links.

The strongest results came from the technical crawlability and schema checks. The page used HTTPS, included a valid canonical URL, had no noindex directive, exposed readable content in the raw HTML, and included JSON-LD structured data in the initial HTML response.

The weaker results were more useful than the score itself. The audit flagged several issues that are common on content-heavy WordPress sites:

The homepage needed a clearer 2 to 3 sentence opening answer that names ScriptByAI and explains what the site does.
The page needed a concise FAQ section for prompt-style questions.
The page needed clearer definitional wording for core concepts.
The homepage needed more internal links to related pages.
The Organization schema needed stronger sameAs links to external authority profiles.
The audited page needed easier access to About, Trust, Company, or Newsroom-style information.

The tool then converted those issues into five priority fixes.

The highest-priority recommendation was to make About, Company, Trust, or Newsroom pages easier to reach from the audited page. The second recommendation was to link active GitHub repositories, examples, or developer docs when the page presents a technical product. The other top fixes focused on sameAs links, a direct opening answer, and a short FAQ section.

This example shows where Free AI SEO Auditor works best. The score gives a fast overview, but the checklist gives the real value. It turns a vague question like “Can AI answer engines understand this page?” into specific page edits that a site owner, SEO editor, or coding agent can act on.

FAQs

Q: Is Free AI SEO Auditor free to use?
A: Yes. The hosted version at freeaiseoaudit.com is free with no signup required.

Q: Do I need to create an account?
A: No account is required. Paste a URL, run the audit, and get results without registration.

Q: What does the 0-to-100 score measure?
A: The score reflects how readable and citable a page is to AI-powered search engines like ChatGPT, Claude, and Perplexity.

Q: How is this different from a standard SEO audit tool?
A: Traditional SEO audit tools score for Google’s crawl and ranking signals. This tool scores for AI retrieval: whether an AI assistant can fetch, parse, and cite the page in a response. The checks target schema coverage, content chunking, raw HTML content availability, and entity disambiguation rather than backlinks, page speed, or keyword density.

Q: Can I use the fix prompts with any AI coding agent?
A: The fix prompts are plain text and work with any coding agent that accepts natural language instructions, including Cursor and Claude Code.

Q: Does the tool audit dynamic or JavaScript-rendered pages accurately?
A: The tool checks whether critical content exists in the raw HTML response before JavaScript execution. Pages that rely on client-side rendering to load their main content may show lower crawlability scores because AI retrieval crawlers often do not execute JavaScript.
