Welcome to the Q&A Forum

According to webmaster tools my Sitemap contains urls which are blocked by robots.txt Our site map is generically generated and encompasses all web pages, whether I have excluded them using the robots.txt file As far as I am aware this has never been an issue until recently. Is this hurting my rankings and how do I fix it? Secondly, webmaster tools says there is over 5,000 error/warnings on my site map. But site map is only 1,400 or so pages submitted. How do I see what is going on?

Webmaster tools is telling me the links to my site has dropped by 100,000 links in one month. Can someone please tell me what may have happened?

Is there any way to know what a competitors traffic is? My website seems to be continuously falling despite attempts to fix and just curious if it's us or an industry issue? Thanks in advance

I have made a bunch of changes thanks to the Crawl Diagnostics Tool but now need to re-run as I have lost where I started and what still needs to be done. How do I re-run the crawl diagnostic tool?
