# A reminder about manipulative or deceptive behavior

Friday, July 12, 2013


Our [quality guidelines](https://developers.google.com/search/docs/essentials/spam-policies)
prohibit manipulative or deceptive behavior, and this stance has remained unchanged since the
guidelines were first published over a decade ago. Recently, we've seen some user complaints about
a deceptive technique which inserts new pages into users' browsing histories. When users click the
"back" button on their browser, they land on a new page that they've never visited before. Users
coming from a search results page may think that they're going back to their search results.
Instead, they're taken to a page that looks similar, but is actually entirely advertisements:

To protect our users, we may take action on, including removal of, sites which violate our quality
guidelines, including for inserting deceptive or manipulative pages into a user's browser history.
As always, if you believe your site has been impacted by a manual spam action and is no longer
violating our guidelines, you can let us know by
[requesting reconsideration](https://support.google.com/webmasters/answer/35843).
