WebCheck and NOTABIS SEO solve related but different problems. WebCheck repeatedly checks explicit production targets for operational regressions. NOTABIS SEO crawls and analyses a broader set of pages for technical SEO findings and recommendations.
Use WebCheck for continuous checks
Choose WebCheck when you need recurring evidence that a homepage, checkout page, API endpoint, robots.txt response, sitemap or TLS certificate remains reachable and behaves as configured.
Use NOTABIS SEO for breadth
Choose NOTABIS SEO when you need a broader crawl, technical SEO analysis, scoring, recommendations, exports or evidence across many pages. It is the appropriate follow-on when a focused WebCheck signal needs wider investigation.
A practical combination
A site owner might use WebCheck to detect that a production canonical or noindex value changed, then use NOTABIS SEO to crawl the site and identify whether the same deployment affected other URLs.
What neither result guarantees
A monitoring result does not guarantee search rankings, and an SEO audit does not guarantee continuous uptime. Keep operational monitoring and periodic analysis as separate tasks with separate evidence.
