Responses to audit scope, free SEO check and ongoing website monitoring.
What happens after the start, how long does it take, and what do you get in concrete terms?

Typical leverages are, for example, 4xx/5xx errors, redirect chains, missing or duplicate titles/meta data, and anomalies in canonicals and indexability. It makes sense to prioritize processing according to impact instead of individual measures without order.
You enter a domain or URL and start the crawl directly in the browser. Seitenreport then checks several pages of your website, evaluates technical SEO signals and creates a dashboard with score, prioritized finds and sample URLs. The result is accessible via a token URL and can be shared.
