What does Site Audit do?
More than 100 checks in 9 categories
Technical, Content, Links, Performance, Structured data, Trust, Local, Social & accessibility and AI Search Readiness. Each issue explains why it matters and how to fix it.
Site Health score and "Fix these first"
A 0–100 score plus the five issues that cost you the most points, so you know where to start.
Crawls like a search engine
Follows your internal links and sitemap, respects robots.txt and nofollow, checks redirects, canonicals, status codes, duplicate titles, thin pages and orphan pages.
Share, compare and monitor
Share a read-only report link on every plan. Paid plans add CSV export, comparison with the previous audit, a print-ready PDF and weekly monitoring with alerts.
Fix with AI and WordPress
On paid plans, get AI-written titles, descriptions and alt text for an issue, and apply some fixes straight to a connected WordPress site.
How Site Audit works
Enter your domain
Type your website and choose a quick audit or the settings wizard (page limit, sitemap or URL list, crawler type, rules).
JoinPostlyBot crawls your site
It fetches one page at a time, at least a second apart, and follows robots.txt. Progress updates live while you wait.
Fix what matters first
Open the report, start with "Fix these first", and re-run the audit to see the score change.
Where does the data come from?
Everything in the audit comes from crawling your own site with JoinPostlyBot (User-Agent JoinPostlyBot/1.0). We don't use third-party SEO data. Speed numbers are measured from our crawler's requests, not from Chrome user data.

Site Audit FAQ
How many pages can the free Postly Rank site audit crawl?
Up to 50 pages per audit and 3 audits a day on the Free plan. Rank Pro crawls up to 500 pages and Rank Agency up to 2,000 pages per audit.
Does the site audit slow down my website?
No. JoinPostlyBot requests one page at a time, waits at least a second between requests (longer if your robots.txt sets a Crawl-delay), and only one audit can run on a website at a time.
Will Site Audit crawl pages blocked by robots.txt?
No. Pages your robots.txt disallows are listed in the report as blocked but never fetched. You can allow or block JoinPostlyBot by name in robots.txt.
What is the Site Health score?
A 0–100 score where every issue costs points based on its severity (error, warning or notice) and how many pages it affects. Fixing the issues under "Fix these first" raises it the most.
