Structured Data & Schema
20 points
JSON-LD, Schema.org types, FAQPage markup, speakable content, and llms.txt help crawlers extract facts without guessing from prose.
Your AEO score measures how ready your website is to be discovered and cited by AI-powered search engines like Perplexity, ChatGPT Search, and Google Gemini. It is calculated across 6 categories worth 100 points total — each targeting a specific signal that AI crawlers use to evaluate content quality.
CRAWLER-VISIBLE SCORING GUIDE
The AEO score is designed for the way AI-powered search engines and answer systems consume pages. Traditional SEO often focuses on keyword targeting, backlinks, and search result snippets. AI Engine Optimization focuses on whether a crawler can read the page, understand the main facts, identify who is responsible for the content, and decide whether the page is complete enough to cite in an answer.
AISEOCheck groups those signals into six weighted categories. A perfect score is not a promise of ranking or citation, but it means the page has the technical and editorial foundations that make AI indexing more likely: machine-readable schema, direct answers, accessible HTML, trustworthy context, semantic structure, and fresh complete content. Low scores point to practical fixes rather than vague advice.

JSON-LD, Schema.org types, FAQPage markup, speakable content, and llms.txt help crawlers extract facts without guessing from prose.
20 points
Direct answers, definitions, lists, statistics, and factual language make a page easier for AI answer engines to quote accurately.
15 points
Critical text should be available in HTML before hydration, with sane canonical URLs, robots directives, HTTPS, and crawlable resources.
20 points
Author names, publication dates, last updated signals, organization details, and citations give AI systems confidence in attribution.
15 points
A clean heading hierarchy, main/article/section landmarks, navigation, footer, and descriptive alt text explain the page structure.
10 points
Recent updates, FAQs, enough depth, and complete answers help the page remain useful for current AI search queries.
An A grade means the page is broadly AI-ready: crawlers can access meaningful content, extract structured facts, follow a clear heading hierarchy, and see trust signals. A B grade usually means the page is close but has a few fixable gaps such as missing FAQ schema, weak authorship, or incomplete freshness signals. C and D grades mean AI systems may understand parts of the page but overlook important details, misattribute facts, or prefer competitors with clearer content. An F grade means critical crawlability, structure, or trust issues are likely preventing the page from being useful to AI answer engines.
The best workflow is to fix the highest-impact category first. For example, make primary content visible without JavaScript before adding advanced schema; clarify definitions and examples before asking AI Insight for rewrite recommendations; add author, date, and citation context before publishing a report for clients. Every scoring detail shown below is user-visible and intended for real readers as well as non-JavaScript crawlers.
