How the SEO, AEO and GEO website audit works?
Every audit starts by fetching the page exactly as a crawler would — no JavaScript execution assumptions, no logged-in state — and reading the response headers, the raw HTML and the robots and sitemap files that govern it. That single fetch then feeds three separate analyses rather than one blended score, because a page can be perfectly indexable and still be useless to an answer engine.
The SEO analysis covers twelve checks on access and on-page signals: status and redirects, indexability directives in both the meta tag and the X-Robots-Tag header, a self-referencing canonical, title and description length, a single H1, heading order, internal linking, image alt text, structured data validity and sitemap membership. The AEO analysis asks a different question: does the page open with a short, self-contained answer, are the sections phrased as the questions people actually ask, is there a factual table or list an engine can lift, and is the authorship and freshness stated in machine-readable form. The GEO analysis looks at citation-worthiness: named sources, original data or method, entity clarity, crawler access for AI agents, an llms.txt file and schema that identifies the publisher.
Each lens produces its own 0–100 score and its own ordered list of failed checks with the correction for each. Scores are never averaged into a single number, because the fixes are different work: an SEO failure is usually a template change, an AEO failure is usually a content change, and a GEO failure is usually an evidence or authorship change.
The paid Complete Website Audit repeats all three analyses on every URL in your sitemap, up to 500 pages, in one pass. The price is quoted from your sitemap before you pay, the page list is locked at that moment, and any page that cannot be reached is refunded automatically at its per-page share.
How do you use this tool?
- 1.Start with the free audit on your most important page — usually the home page. Paste the URL and read all three scores side by side before changing anything.
- 2.Fix the SEO failures first. Answer engines quote pages that classical search can already retrieve, so indexability and canonical problems block the other two lenses.
- 3.Work the AEO list next: add a 40–80 word direct answer at the top, rewrite section headings as questions, and add a facts table where the page states numbers.
- 4.Then the GEO list: name your sources, state who wrote the page and when it was last checked, and make sure AI crawlers are allowed in robots.txt.
- 5.When one page scores well, buy the Complete Website Audit to see which of the same failures repeat across the rest of the sitemap — that ranked, site-wide list is where the real gains are.
What can this tool not tell you?
- A perfect score is technical eligibility, not a ranking promise. Authority, originality, competition and demand still decide where you place.
- The audit reads the served HTML. Content that only appears after client-side rendering may score lower here than it does for a crawler that renders — which is itself a signal worth acting on.
- AEO and GEO checks are practical heuristics drawn from how answer engines currently select and cite sources. They are reviewed periodically; they are not an official published standard.
Why one blended score hides the work you actually need to do?
Most audit tools return a single number. That is comfortable to read and almost useless to act on, because the three disciplines fail for unrelated reasons and are fixed by different people. A missing canonical is a developer ticket. A missing direct answer at the top of the page is a writing task. A missing source citation is an editorial policy question. Averaging those into one figure tells you that something is wrong without telling you who should fix it, so nothing gets fixed.
Running the lenses independently also exposes the ordering that matters. Answer engines and generative models overwhelmingly quote pages that conventional search can already retrieve, so an indexability failure quietly caps the value of every AEO and GEO improvement you make. When you see a strong AEO score sitting behind a failed SEO check, you know the content work is already done and a single technical change will release it.
The site-wide view adds the third dimension: frequency. A failure on one page is a task; the same failure on 180 pages is a template defect, and fixing it once in the layout moves the whole site. That is why the Complete Website Audit ranks fixes by how many pages they affect rather than listing pages one by one — a 400-page report nobody reads helps nobody.
What do worked examples look like?
A marketing site that ranks but is never quoted
SEO scores in the nineties, AEO in the forties. Every page is indexable and fast, but each one opens with a paragraph of positioning language instead of an answer, and none carry a facts table. The fix is editorial and repeatable: a 40–80 word answer directly under each H1 and one structured table per page.
A 300-page documentation site
The Full site audit quotes 300 pages, finds the same three failures on 240 of them — no author, no last-checked date, and AI crawlers disallowed in robots.txt — and ranks them at the top of the report. Three template edits lift the GEO score across the whole site in an afternoon.
What do people ask most about this tool?
What is the difference between SEO, AEO and GEO?
SEO decides whether a search engine can crawl, index and rank your page. AEO decides whether an answer engine can lift a clean, self-contained answer from it. GEO decides whether a generative model will name you as the source of that answer. A page can pass one and fail the other two, which is why we score them separately.
Is the audit really free?
Auditing one page — all three lenses, every check, with the correction steps — is free and needs no account. Only the multi-page Complete Website Audit is paid, because it crawls and analyses every page in your sitemap.
How much does the Complete Website Audit cost?
A Quick site audit is $9 flat for your home page plus a handful of key pages. A Full site audit is $0.25 per page with a $29 minimum, covering every page in your sitemap up to 500. Sites larger than 500 pages are handled as an Enterprise engagement with negotiated pricing.
How long does a full audit take?
Most sites finish in under 30 minutes. You do not need to stay on the page — we email a private link to the report when it is ready.
What happens if some pages cannot be reached?
Unreachable pages are listed at the end of your report with the exact error, and their share of the payment is refunded automatically without you asking. If no page could be scored, the whole order is refunded.
