Non-Status 200 Pages

Non-Status-200 URLs - Raptor SEO Data

Non-status 200 pages are URLs that return a response / status code that is not ‘200’, which means that they are inaccessible to both users and robots. The reason for this inaccessibility may vary from the page redirecting to a server error.

Each of the video guides in this series explain the following about the web and SEO data that we provide. We don’t just collect or scrape data, we process and analysis this with advanced algorithms that are designed to save you time and present you with data that tells a story. Check out the video below to see what this metric means and why its importnant.



There are many status codes that are not ‘200’ but because most mean the page is not accessible for some reason, we split these out into two sections ‘200’ & ‘non-status-200’. As part of our crawl pro9cess we log every response code returned by every URL we crawl, you can see this in the reporting section and download this into various formats.

To better understand what data, we show in our SEO software means, what it means for your site and how to best utilise that data. The data that our powerful SEO software that we produce provides hundreds of types of data, some of this is scraped from sites and some of it we calculate and analyse for you.

The list below summarises the non-status 200 response codes.
