Warnings about cookies, or other legal disclaimers.

Google Product Manager Doantam Phan, explained on a webmaster’s blog that while this change is new, it is one of many signals Google uses to rank websites and that a site with compelling, relevant content may still rank well, even with some intrusive interstitials, and it will take up to a year for publishers to start seeing any changes. If anything, the hope is to challenge these publishers to find ways to make revenue without resorting to obnoxious, intrusive advertising and encourage a better experience for the user.
