The free generative engine optimization audit in your browser
OctoCheck is a Chrome extension that docks beside any page you open. One click, 100+ checks across eight areas, and a grade for how AI search engines read, trust, and cite the page.
An audit you can act on
Every finding comes graded, sorted by impact, and paired with a fix.
A score with no flattery
Weighted by severity and capped by fatal failures. A page that blocks AI bots cannot score well on pretty formatting, so the number means something.
Findings in plain words
Findings name what broke and where, with the exact fragment from your page when it helps. No error codes, no jargon, no guessing which tag it meant.
A fix for every finding
Each issue ends with what to change, and links to a plain-language guide when you want the why behind it.
AI and your visitors see two different pages
A person opens your page and sees everything: the text, the images, the layout. Many AI engines see far less, sometimes almost nothing. OctoCheck compares both views on every scan, so you know exactly how AI sees your page.
What most AI bots read
- H1 heading: missing
- Body content: empty
- Schema markup: missing
What your visitors see
- H1 heading: present
- Body content: 1,400 words
- Schema markup: present
And it doesn't stop at the page
- robots.txt
- sitemap.xml
- llms.txt
- HTTP headers
- response status
- and much more
One scan pulls the whole picture: the files that steer crawlers and the headers they negotiate with.
Eight areas in one pass
Every scan runs 100+ checks across everything that decides whether AI engines can find, read, and trust your page.
AI bot access & crawlability
Whether AI crawlers can reach the page at all, starting with the rules that let them in.
Indexability & discoverability
The signals that decide whether the page exists for engines: status, canonicals, sitemaps, directives.
HTML structure & meta
The document skeleton parsers lean on: title, meta, language, headings, landmarks.
Schema & structured data
The markup answer engines quote, and whether it is valid, wired up, and visible without JavaScript.
Content structure & format
Whether the writing is shaped for extraction: summaries, lists, tables, quotable passages.
Content authority & trust
Why an engine should believe the page: authors, dates, sources, contact, identity.
Rendering & performance
What makes bots give up early: page size, compression, render-blocking code.
AI standards & LLM visibility
The new AI-native surface: llms.txt, snippet directives, content signals, TDM reservation.
