Choosing well
Start with the access model
A free plan is available from tools in this category, and a free trial is offered by tools on the list. Check what the free access includes before comparing paid plans.
Review the paid-from price alongside crawl limits and reporting features so the entry plan matches your work.
Match pages per crawl
Pages per crawl shows how much of a site an audit can process in one run. Compare that limit with the size of the sites you manage.
A smaller crawl allowance may suit a focused check, while larger projects need a plan built for broader crawls.
Check audit timing and coverage
Audit frequency tells you how often checks can run. Choose a schedule that fits how often your site changes.
Compare audit coverage as well, since tools can differ in the areas they inspect and report.
Plan for teams and clients
Sites or projects indicate how much work you can organise in one account. Check this against the number of properties you need to monitor.
White-label reports matter when reports need your own branding or must be shared with clients.
Confirm your working setup
Tools on this list run on web, API, Windows, macOS, Linux or as browser extensions.
Native integrations can reduce manual steps between an audit and the other services in your workflow.
