I have not seen this new advice thing the Adsense have when you log in. I thought it was part of my report and had not paid much attention to it.
Google Adsense gave me this advice for June up to September
You may be filtering ads that monetize well on your site.
Basically they want me to stop block sites but I won’t. I have to many domain names that I have in Adword and I don’t want them to mix off course. I also have some very bad sites like eBay that does pay very badly per click. So I am sure Google Adsense want me to stop blocking them but the can forget it.
My friend Chris over at the Adsenseguide forum have run to a stand still so I thought I might give him a hand to promote his nice forum and website that has loads of information about Adsense. He was one of the first good sites and it is still updated. Chris also made the great Revenue Monitor that tracks your Google Adsense Clicks.
If you are new to Adsense this is a great place to start because there is so much free information.

Remember to use Google Adsense crawling reports every week
You should consider check you Adsense account sometimes for error that might come on the report crawling page on Google Adsense.
The URL when you have logged in is:
https://www.google.com/adsense/report/report-crawling
It will show URL that is not showing up properly and need to be fixed otherwise you might not get any income from them
If there page show any problem you should try to fix it as soon as possible it can be anything from that Google can not crawl the page to missing pages.
