I have a website and we recently changed content management systems. With the new system came new URLs/hierarchy. Google Webmaster Tools doesn't have any issues with the site and I get no crawler errors. But AdSense seems to still be looking for URLs on my old site and I get tons of "Page not found" errors.
What can be done to get Adsense to crawl the new sitemap?
This is on the crawler errors page. It says "Blocked URLs" and then to the side of the URL it lists "Page not found."
It explains: "Our crawler was unable to access the pages listed in the ’Blocked URLs’ column to determine the content and display ads. Click the ’plus’ icon beside each domain to see an expanded list of affected URLs. When our crawler can’t access your content we won’t show ads, resulting in lower revenue and coverage. Follow the link in the ’Error’ column to learn how to correct these errors."
I just want it to forget these pages exist, because they don't anymore.
