google-webmaster-tool-guidelineEarly this morning, Google announced that they have updated their guidelines regarding site redirecting.  Two of their guideline documents were updated, and should now more easily clarify what are sneaky redirects that are against their webmaster guidelines.

Expanding upon their guidelines, Google wanted to make sure that webmasters were clear about using sneaky redirects through mobile site detection and redirection, and how it isn’t allowed if the content on the separate pages aren’t the same.  In their revised guidelines, Google says that “desktop users receive  a normal page, while mobile users are redirected to a completely different spam domain.”  If webmasters use this type of redirection, they need to know that this is not in accordance with Google’s guidelines.

Google has given two new examples of sneaky redirects that can be found on their guideline page:

  • Search engines shown one type of content while users are redirected to something significantly different.
  • Desktop users receive a normal page, while mobile users are redirected to a completely different spam domain.

In addition, Google has updated the hacked sites page with more content surrounding redirects:

“Hackers might inject malicious code to your website that redirects some users to harmful or spammy pages. The kind of redirect sometimes depends on referrer, user-agent, or device. For example, clicking a URL in Google search results could redirect you to a suspicious page, but there is no redirect when you visit the same URL directly from a browser.”

Finally, a warning was added by Google stating, “with any violation of our quality guidelines, we may take manual action, including removal from our index, in order to maintain the quality of the search results.”
