How can I audit my website SEO for free?
Enter your website URL in Corpus Plan to start a free preview. When you want the full findings, create a free account with your email and a password. The report brings together five scored areas: AI citability, SEO, speed, trust and content. You do not need Pro to view your first full report.
What does a free SEO audit check?
Corpus Plan checks five areas of your website, each scored from 0–100. The report explains the findings behind those scores, with pass, warn or fail results. When a check cannot complete, it says “couldn't verify.” Use the findings to inspect a particular problem, rather than treating the overall score as a verdict on your business.
Examples of checks
AI citability / GEO
JSON-LD structured data, AI-crawler rules, readable page content, question headings, answer structure and llms.txt
SEO
Titles, meta descriptions, headings, canonical URLs, robots.txt, sitemap, image alt text and internal links
Speed
Response time, page weight, compression and redirect chains
Trust
Contact information, contact-page access, privacy and terms links, and calls to action
Content
Readable copy, indexable pages and signs of site maintenance
The audit reads up to 20 pages from the submitted site, with capped checks of its own links and assets. It does not fill in or submit forms. This is a limited crawl, not a complete inventory of every page on a large website.
Read the audit methodology for the published checks and thresholds.
Does the audit check AI search visibility?
Corpus Plan includes structural AI-citability checks: crawler access, structured business information and the way answers are presented on your pages. Those checks are separate from model-output visibility. A visibility result records whether one model names a business at one moment; it does not establish how every AI service will answer or promise a future mention.
Treat llms.txt as a file check, not evidence that assistants will cite you. Corpus Plan does not guarantee rankings, traffic, revenue or AI mentions.
What should I fix first after an SEO audit?
Start by inspecting critical findings about page access, crawling or indexing. Read the reason and fix hint before changing the site: a finding needs to be checked against what that page is supposed to do. Then review the remaining SEO, AI-citability, speed, trust and content issues against the work your website actually needs.
Use the published methodology to understand the test behind a finding. “Couldn't verify” is a limit of the check, not proof that something is broken. If a finding appears wrong, follow the audit-accuracy instructions in the site footer and include your report link.
What is the difference between a free audit and the Pro workspace?
The free account lets you save up to three sites and includes the full audit report, an audit-based action plan and a shareable report link. Pro costs $99 per month for up to 10 sites on one account. Its work includes GEO file drafts and tools to create, edit and export social drafts. These are materials to review and use, not completed changes to your website.
Start with the free findings. Consider Pro when you need help preparing the next pieces of work; payment is not required to reveal your first full report.

Free SEO audit FAQ
Can I get a free SEO audit without an email address?
Corpus Plan offers an anonymous website preview without an email address. To save your own new audit and view all findings, create a free account with your email and a password. You do not need an account to read an existing saved report through its share link.
Do I need an account to see the full SEO report?
For your own new audit, yes: free Corpus Plan signup with email and password lets you save it and view the full SEO report and its audit-based action plan. Pro is optional. Recipients of an existing saved report’s share link can read it without an account.
Can I run unlimited free audits?
No. Corpus Plan’s free account lets you save up to three sites. Separately, free site looks are limited to three per connection per day. The daily limit is not additional saved-site capacity or a promise of unlimited audits or automatic monitoring.
