Limits and fair use

Plan limits

• Free: 1 site, up to 50 pages scanned per site, 2 scans a day and 7 a week. Each list, finding and download shows its first 50 results; the totals are always complete. No AI assistant connection (MCP) and no Google PageSpeed results.
• Pro ($9 a month): 3 sites, up to 1,500 pages per site, 4 scans a day and 20 a week, full results everywhere, MCP and PageSpeed.
• Business ($29 a month): 10 sites, up to 10,000 pages per site, 8 scans a day and 40 a week, and everything in Pro.
• Scans count when you start one or use Clear data and rerun, over the last 24 hours and the last 7 days. Stopping and resuming a scan does not use another one, and removing a site does not give its scans back.
• When a site has more pages than the plan covers, the first pages found are scanned and the rest wait; you get a message. After a downgrade, sites beyond the plan's count stay visible but cannot be scanned.
• Only one scan can be queued or running per site.
• Many users share one crawler. Scans are scheduled fairly between accounts, so a scan may wait in a queue; its position is shown.

Your plan and what you have used are in Settings > Plan.

How we treat your site

• About 2 requests per second per site, never more than 4 at the same time, slower if your robots.txt sets a Crawl-delay.
• robots.txt is obeyed; blocked pages are not fetched, are listed under "Blocked" on the Pages list, and do not count in the health score. They are flagged as a problem only when your sitemap lists them. If it answers with a server error or cannot be reached, the scan pauses and retries, and fails after about 10 minutes.
• noindex pages (meta robots or X-Robots-Tag) are fetched but left out of the page checks and the health score; the scan warns if your sitemap lists one. Links on a nofollow page, and links marked rel="nofollow", are not followed to find new pages.
• Only addresses on your own site are fetched. Other websites are never visited.
• The crawler identifies itself in its User-Agent and links to its info page.

MCP

• Available on Pro and Business. On Free the connection is refused with a message to upgrade.
• 120 requests per minute per connection; over that you get HTTP 429 with a Retry-After header.
• List tools return at most 50 rows per call; use the offset to page. Very long answers are cut at 60,000 characters.
• Access tokens last 1 hour, refresh tokens 30 days. Up to 10 clients per account.
