What it checks

An exhaustive checklist, grouped so you can act on it.

The checker runs every item below on a single URL and marks each one as pass, warning, fail, or advisory.

SEO checklist

  • Crawlability and indexability: noindex, canonical, URL format, HTTPS
  • Title and meta description presence, length, and uniqueness
  • Headings: a single H1, ordered hierarchy, content length
  • Images: alt text on every image, alt quality, dimensions, lazy loading
  • Links: internal and outbound links, descriptive anchor text
  • Structured data: JSON-LD presence and validity
  • On-page technical: charset, lang, viewport, Open Graph, Twitter card, duplicate IDs, mixed content

AEO checklist

  • Answerability: question framing, a direct answer up front, skimmable structure, FAQ section
  • Structured answers: FAQPage, HowTo, Article, and BreadcrumbList schema
  • Citation readiness: sources, dated facts, author signals
  • Extraction readiness: server-rendered content, no noscript-only content, no collapsed core answers
  • AI crawler policy: whether known AI crawlers are blocked in robots.txt (reported, never changed)

FAQ

Questions about the checker.

What is the difference between SEO and AEO?

SEO optimizes a page for classic search engine rankings: titles, meta descriptions, headings, links, and crawlability. AEO (Answer Engine Optimization) optimizes the same page to be parsed and cited by AI answer engines and featured snippets, which care about direct answers, structured data, and server-rendered content.

What does this checker test?

It fetches a single published URL and runs a grouped checklist across crawlability, title and meta tags, headings and content, images and alt text, links, structured data, on-page technical signals, and a dedicated set of AEO checks for answerability, structured answers, citation readiness, and extraction readiness.

Does submitting to IndexNow guarantee indexing?

No. IndexNow notifies participating search engines that a URL changed. Whether, when, and how they recrawl and rank the page is their decision. It is a notification, not a placement.

Why does the checker report AI crawler blocking without changing it?

Blocking or allowing AI crawlers is a site-owner policy choice, so the tool only reports whether known AI crawlers such as GPTBot, ClaudeBot, and PerplexityBot are blocked in robots.txt. It never edits your robots.txt for you.
