Hidden Redirect or Google Ban

Today, it is increasingly common to encounter blocking of websites by search engines due to unauthorized redirects of users to other resources (for example, to WAP-click affiliate networks).
Such sanctions can be applied by Google and other search engines if advertising code is found on your website. Usually such code is placed either by the site owner themselves, or by a hacker who hacked the site. This is done for the purpose of additional earnings on teasers (advertising banners). Such a site will not be marked as threatening security, since it does not redirect users to infected pages, so it will simply be removed from search engine results.
A site can be banned by Google or another search engine because search results are based on the relevance and usability of sites, and unauthorized advertising hurts these.
The site is not blocked permanently, but for a certain period of time, so if the owner reconsiders their attitude to work and fulfills all the conditions of the search engine, the site will return to search results.
Such sanctions most often hit webmasters who sell mobile traffic. As a rule, visitors are redirected only when they open the site from a mobile phone, so the problem is not always easy to notice.

What to Do If Your Site Was Banned by a Search Engine Due to Redirection?

If search engines have imposed sanctions on your resource due to hidden redirection, the solutions to the problem are as follows:

• Remove all banners and teasers that you have placed on the site. Even if you consider them verified and reliable. There is a list of trusted teaser networks that you can use.
• If you are sure that you did not personally enter the advertising code, then check the site's security: check for third-party scripts, perform scanning with AI-BOLIT antivirus, check for the presence of the message_for_oss.pdf file in the search engine cache,

  inurl:message_for_oss.pdf site:mysite.ru

• analyze statistics of outgoing clicks to external resources (LiveInternet, Yandex.Metrica counters) for clicks to affiliate sites, teaser or advertising networks.

Even if you have completely cleaned the site and are absolutely sure it is clean, do not submit it for review right away. Search engines recommend waiting at least a month before requesting a review. Otherwise, you will simply get a refusal and still lose time.
