What the audit checks
Five pillars, checked the same way every time.
Each pillar is scored 0–100 from concrete checks — pass, warn, or fail, with the reason written out. Where a check can't complete, the report says "couldn't verify" instead of guessing.
SEO
Page titles, meta descriptions, heading structure, canonical URLs, robots.txt, sitemap, image alt text, internal links, 404 handling.
Speed
Response time, page weight, compression, redirect chains, mobile viewport, HTTPS.
Trust
Visible phone, email, and address, a working contact page, privacy and terms links, a clear call to action, analytics.
Content
How much readable copy the pages carry, how many pages are indexable, and whether the site shows signs of being maintained.
GEO — AI answers
What AI assistants can use: llms.txt, JSON-LD structured data, AI-crawler rules in robots.txt, how extractable the content is, question-shaped content, Open Graph tags.

Questions
Straight answers before you run it.
What does the free audit check?
Five pillars, each scored 0–100 from concrete checks: SEO, speed, trust, content, and GEO — how AI assistants read your site. Every check passes, warns, or fails, with the reason written out.
Is the free audit really free, with no email wall?
Yes. One full audit per site, with every finding and every score on a shareable report page. No account, no email address, nothing blurred out.
Does Corpus Plan fill out or submit forms on my site?
No. The audit only fetches and reads up to 12 pages of the site you submit. It never fills in or submits forms, and never fetches anything beyond that site's own pages.
How does the AI-visibility check work?
We ask one language model the kinds of questions your customers ask and record whether your business appears — one model, at one moment, labeled as such. It's a snapshot, not a guarantee: no tool can promise an AI mention.
How much is Pro?
$99 per month per account, up to 5 sites. Billed through Stripe; cancel any time from the billing portal.
What this is not
Plain terms.
- We don't guarantee rankings or AI mentions — nobody can, and be wary of anyone who promises them.
- The free audit fetches up to 12 pages of the site you submit, and nothing else.
- We never log personal data from your pages and never train models on customer data.
- A low score means our checks found specific problems, listed with fixes — not that your business is failing.
