What gets checked

24 Signals, Two Scores, One List

Search engines and answer engines want overlapping but different things. The checker splits them so you can see which side needs the work.

SEO / 60Can Google crawl, understand and trust the page?

HTTPS, response time, title and description length, one H1, heading order, canonical, viewport, language, alt text, robots.txt, sitemap, Open Graph, internal links, page weight and word count.

AEO / 40Can an AI assistant quote you with confidence?

Valid JSON-LD, a declared Organization or Person, FAQ or Article schema, llms.txt, AI crawlers allowed, question led headings, a direct answer under the H1, and visible author plus dates.

DRDoes the domain carry authority?

Domain rank, backlinks and referring domains from OpenSEO's DataForSEO index, converted to a 0 to 100 rating. Under 30 and links are the ceiling, over 50 and content is.

Why AEO now

Buyers Ask the Assistant Before They Search

The shortlist is written before the click. When a buyer asks ChatGPT or Perplexity which vendors to consider, the answer names three to five companies. If yours is not in that answer, your landing page never gets the visit. That is why the AEO score sits next to the SEO score instead of inside it.

Entities beat keywords. Answer engines resolve organisations, people and products, then look for consistent facts about them across your site, LinkedIn, directories and press. Organization and Person schema with sameAs links is the cheapest fix with the largest effect, which is why it carries 12 of the 40 AEO points together with FAQ schema.

Say it in the first sentence. Models lift the paragraph that answers the question most directly. A 40 to 80 word answer right under the H1, a few H2s phrased as real questions and an llms.txt that points to your best pages are the pattern I used to take AccuKnox to 27.72% AI visibility. The full story is in the AEO and SEO case study.

Authority still gates it. A DR under 30 means fewer citations whatever the markup says, because engines weight sources they already trust. Check how likely you are to be cited today with the AI visibility checker, then fix the technical layer here.

Common questions

SEO and AEO Score FAQ

What is an AEO score?

AEO stands for answer engine optimisation, getting cited by ChatGPT, Gemini, Perplexity and Google AI Overviews. The AEO score measures the signals those engines rely on: valid structured data, a declared organisation or person entity, FAQ or article schema, an llms.txt file, AI crawlers allowed in robots.txt, question led headings, a direct answer under the H1, and visible author and dates.

How is the SEO score calculated?

The tool fetches your page like a crawler and checks 16 on page and technical signals: HTTPS, response time, title and meta description length, a single H1, heading order, canonical, viewport, language, alt text, robots.txt, XML sitemap, Open Graph tags, internal links, page weight and word count. Each check carries a weight and the SEO score is out of 60, the AEO score out of 40, 100 in total.

Where does the Domain Rating come from?

From OpenSEO, an open source SEO platform that reads backlink data from DataForSEO. The tool asks OpenSEO for the domain's rank, backlinks and referring domains and converts the rank to a 0 to 100 rating so it reads like the DR you know from Ahrefs. It is an estimate from a different index, so expect it to differ a little.

Does the checker look at the whole site?

It scores the one URL you enter plus three site level files: robots.txt, sitemap.xml and llms.txt. Run it on your home page first, then on the two or three pages that matter most for pipeline, such as a product page and a comparison page.

Is my URL stored?

The URL is fetched once to produce the score and the result is cached in memory for a short time so repeated checks do not cost extra. Nothing is written to a database and no account is needed.

What should I fix first?

The action list is sorted by priority and impact. Anything marked high blocks indexing or citation outright, such as a noindex tag, a blocked AI crawler or missing structured data. Clear those, then work down the mediums. If your Domain Rating is under 30, authority is the real ceiling and link earning belongs on the plan.

Scores are a snapshot of one URL at one moment and a guide for prioritising work, not a ranking guarantee. Domain Rating is an estimate from OpenSEO's index and will differ from Ahrefs, Moz or Semrush. Built by Syed Hadi.
