Hello, I don't know it's the correct place to ask this question or not! A few weeks ago I have trash my content because It was copied and now I am fixing one by one and Webmaster account show this stats on Dashboard In Sitemaps 117 Not found 1,542 Restricted by robots.txt 1,015 Unreachable 3 How Can I fix this error's?
In the page where the crawl errors are found there is an explanation that mentions the nature of the error, it can either be a page not found error. That means that the page does not exist anymore or has been taken down. Click on the "In sitemaps" and you will see the errors in your sitemap. In the "Unreachable", it means that the Google crawler could not reach the desired page.
