When you make a request to a web page using your browser, it is possible that it returns different status codes or that the route to the page contains intermediate redirects. Search robots see these status codes returned by requests and these can have a decisive impact on the crawling and indexing of a site's pages, so it is vital for an SEO to be able to identify any casuistry related to status codes.

With Perseo you can view the status code returned by each of the requests that are part of the route to the page, identify network or DNS errors and also view the HTTP headers of each request.
