Today, I got an email from google adsense,which saying
” While reviewing your ad implementation, we noticed that your robots.txt file is currently preventing our AdSense crawler from reaching a significant number of pages with ads in your account.” I have searched for this problem, and found a lot people got this mail.Then , I check my sites’ robots.txt, and add the
Disallow: ” which the adsense suggested. Most of my sites are wordpress and blogger, my robots.txt isn’t blocking any bots on pages where ads are displayed. just like this site: dobeweb.com, you can visit http://www.dobeweb.com/robots.txt, and there is nothing. For blogger, and I have checked the blogger robots.txt, just browse http://yoursitename.blogspot.com/robots.txt,what you see??
So, there is nothing wrong with these robots.txt. I think this mail have send to all of us.
you can use edit the blogger robots.txt if you have added sitemap to google in google webmater center.
