i notcied for first time in my adesnse account this in Site Diagnostics : Site Diagnostics View detailed diagnostic information about the pages Google crawls to display relevant ads. If our crawler finds any issues with your pages, they'll be listed in the table below. We encourage you to resolve these issues in order to allow us to crawl more of your pages and provide relevant ads. For help resolving issues with any blocked URLs, please visit our Help Center This crawl report is updated weekly, and we are unable to accommodate requests for more frequent crawling. Please also keep in mind that this report is not exhaustive. after this i see report , in the report i see a line say Blocked URL Reason Blocked [?] Last Crawl Attempt Failed Attempts and some url of my site listed.... any help... is this related to banning or what?
Don't worry, that only mean that the AdSense bot was unable to crawl some of your pages whatever the reason. Check your robots.txt file to be sure the bot isn't blocked, but if you didn't changes anything lately, it's can be a problem from Google Side. (sometimes they report being unable to crawl URLs that are just fine.) Check the URLs they listed to be sure, but if you're site has been down at the moment the bot came, you have this kind of message. But nothing related to ban
not sure what that message means exactly, but perhaps your host was down for a moment or something, hard to say but it seems just like a minor issue that will easily be resolved.
Host being down when google spidered site is my guess. Site might have had a problem when they visited.
No, there is no ban. Sometimes if you make changes to your site, the spider may not be able to find some pages and thus the error. Nothing to worry about.
