Looking at Adsense Site Diagnostics i see every single day same errors: Blocked UR: 3 or 4 OLD AND NON EXISTENT urls Reason Blocked: Not Found. Of course you can't find them moron, they don't exist for one year!!! WTF is going on with this crawler? Why is he so stupid to look after old files? The sitemap only shows the new files... for one almost a year now. This pisses me off cause it looks the site is losing the quality of Pay per Click because of these errors. Any idea about this?
Find the source of the link from where the bot crawled ur dead pages, then removed the link. IMHO the source of the link is still existed. Simple solutions perhaps you can redirect to your homepage.
The bot is crawling: > www domain . com > pagehere.html > anotherpage.html > andanotherpage.html But those pages don't exist for some time now and they are not at server. In fact, it was a html site and now its a WP based site.
