The Lighthouse for AI search

Is your site
visible to AI?

ChatGPT, Perplexity, and AI Overviews only cite what they can parse. Drop in a URL and get a score across 6 dimensions, plus a fix brief. Run it yourself, or send it to a client as a report. No API calls.

Rescan the same site twice for free. The 3rd rescan (then 6th, 9th…) bills like a new scan.

One scan, two jobs

What a reading actually gets you

Fix it yourself

Scan your site, export the report, and hand your dev (or Claude, ChatGPT, Cursor) the fix list.

Turn it into billable work

Scan a lead's public site, export a branded proposal with your name on it, and pitch the fix.

Watch a reading develop

A 40-second walkthrough of a real audit, start to score.

How it works

No LLM calls. No black box.

AI can only quote what it can reach, parse, and trust. That's a technical gate, separate from how good your writing is. Litmus checks it the same way every time: rule-based, not another model guessing on your behalf.

01

Drop in a URL

Your homepage, or any page. Add up to 3 competitor URLs for a side-by-side.

02

We crawl and render it

Every page, fetched twice: raw HTML and a full render. JavaScript-heavy sites still get scored fairly.

03

Six reagents, one reading

6 dimensions per page, rolled into one site-wide composite score.

04

Export it

For your AI or dev to work through, or as a branded proposal to send a client. Not just a number to stare at.

Questions

Why not just ask ChatGPT or Claude directly?+

AI models aren't consistent — same question, different answers. Litmus is rule-based instead: same input, same score, every time.

What is this scoring model based on?+

Our own testing against real AI crawlers, plus published research on AI citation behavior.

Does this call ChatGPT, Claude, or any LLM to generate my score?+

No. Every check is rule-based: DOM parsing, robots.txt, structured data, readability. No API costs, no randomness.

How is this different from a normal SEO audit tool?+

SEO optimizes for search rankings. Litmus checks a different gate: whether AI engines can access, parse, and quote your pages.

What counts as a "page" in my max pages setting?+

Any URL Litmus finds via your sitemap or internal links, up to the limit you set. 200 pages max per scan.

Do rescans cost a credit?+

First 2 rescans of a site are free. The 3rd (then 6th, 9th…) bills like a new scan.

Do you store a copy of my site?+

No. We store your scan results (scores, issues, metadata), not a mirror of your content.

What does one credit cover?+

1 credit = 1 billed scan, any number of pages or competitor URLs. Free rescans don't touch your balance.

What do I actually get for a credit?+

A fix list for your dev, plus a branded PDF proposal you can send a client, on every plan.

Can I use this to resell audits to clients?+

Yes. Scan any public site, no permission needed, and export a branded proposal with your name on it.

Do I need to be an SEO expert to sell this?+

No. Litmus finds and ranks the gaps — you explain the report. Most fixes are things Claude or Cursor can do too.

What should I charge to fix what a scan finds?+

Your call. Free audit, paid fix: the split every audit-led pitch runs on.

Six reagents

What actually gets measured

Technical Optimization

Can crawlers even get in? Robots.txt, sitemap, structured data.

Does it answer fast? Clear headings, FAQ blocks, no fluff first.

AI Comprehension

Can AI tell who you are? Consistent naming, plain writing.

Citation Authority

Can it verify you're real? Evidence links, named testimonials.

Content Freshness

Is it current? Visible publish and update dates.

Blog / Content Visibility

Litmus vs a manual GEO audit

A manual audit is one consultant's opinion, once. Litmus runs the same rule-based checks every time, so you can track whether a fix actually moved the score.

Where this fits

Content is the key.
We make sure AI can turn it.

Getting cited by AI comes down to your content. Litmus checks whether AI can even reach it: the six things measured up the strip beside this. Want the content and strategy behind the gate built too? That's the bigger, harder half of GEO, and it's what Aivirex builds directly.
