Site audit
What the crawler checks, what the first 50 pages cost (nothing), and how credits pay for the rest.
An audit crawls your site from its start URL, follows internal links, reads each page, and groups what it finds into issues — broken links, missing titles, duplicate content, thin pages, and about thirty other checks — each with a plain-language fix.
There is no headless browser and no Lighthouse score. The crawler reads HTML and headers the way a search engine's crawler does, plus your own server's response time, which is the only performance signal it reports.
What it costs
The first 50 pages of every audit are free, on every plan. That is deliberately enough to fully audit most small marketing sites and landing pages without spending a credit.
Past 50 pages, a crawl costs 1 credit per 2 pages, drawn from your research allowance first and then your credit balance — the same allowance-first order as keyword research. Free stops at 50 pages and one audit per project per month; paid plans can go further, up to a per-plan ceiling:
| Plan | Pages per audit | Scheduled audits |
|---|---|---|
| Free | 50 | — |
| Starter | 1,000 | Monthly |
| Pro | 5,000 | Weekly |
| Agency | 10,000 | Weekly |
What happens to a blocked start URL
If your start URL returns an error, blocks the crawler outright, or is disallowed by
robots.txt, the audit fails immediately and nothing is charged — there is no partial
crawl to bill for. The audit screen tells you which of the three happened.
Resuming and history
A crawl is resumable: if it is interrupted, restarting continues from where it left off rather than re-crawling pages it has already read. Every completed audit is kept for as long as your plan's retention (3 on Free, 10 on Starter, unlimited on Pro and Agency), so you can compare a fix against the audit that found the problem.
Scheduled audits
Starter and above can turn on automatic audits (monthly on Starter, weekly on Pro and Agency) from the audit screen. A scheduled run is capped at 1.5× your last manual crawl's page count, so a runaway crawl on a site that suddenly grew cannot silently spend your whole allowance — it audits roughly what you last asked for and no more. A scheduled audit that would run over your remaining credits is skipped rather than partially charged, and the screen says why.
