Sitechecker: audit and monitor all your clients’ websites in one place

Sitechecker comes into its own as soon as you manage more than a handful of sites. Its real talent isn’t finding keywords or picking apart a competitor’s links, but keeping watch: a homepage that goes down, a noindex tag slipped in by mistake during an update, a redirect that breaks, a tracking code that disappears. For an agency, that alert alone is worth a good part of the subscription. The interface is clear, the explanations make sense to non-specialists too, and unlimited users spare you the unpleasant surprise of suites that charge for every extra seat.

Its data has the advantage of coming from your own sites: its own crawler for the audit, Search Console and Google Analytics for traffic. Nothing is estimated, then, but there is also nothing about the market beyond your projects. Keyword research is limited to Google’s suggestions and a few dozen checks a month, and there is no link database or competitor traffic estimate comparable to those of Semrush or Ahrefs. It is a monitoring tool, not a research tool.

For three sites, the first plan seems expensive if you only have one site to monitor, and the math only becomes attractive as you add projects. The interface can also be slow on large accounts, and some analyses are less thorough than those of a specialized crawler such as Screaming Frog or Sitebulb. The subscription renews automatically and only the first payment is refundable, within 48 hours: once the trial has started, the countdown doesn’t send you a reminder.
