When tapping a web page with a smartphone, everyone should have experiences that "advertisement covers the entire page and you can not see the page you want to see right away." Google has launched a penalty to display a web page with such mandatory advertisements under the search results.

A penalty is imposed on Google's type of advertisement that we call "problematic transitions", so pop-up advertisements that tap the link immediately after you tap the link, or you can not see the content as you scroll, or if you do not want the user to dismiss it Interstitial ads that can not transition to pages, and interstitial advertisements that cover the entire page on the page. Simply put, if users hide the page they want to see, display ads, or forcibly manipulate the ad, it means that they may be penalized by Google.


Google does not accept penalties if it is a "small" pop-up advertisement, but we do not know the size, and we do not know how small size it corresponds to "small". Also, not all pop-up advertisements are applicable, pop-ups asking for consent to acquire cookies as necessary, and interstitials to check age before displaying content are excluded.


Please note that this penalty only applies to mobile pages and does not affect desktop pages. In addition, the penalty applied to the mobile page is that only the page moved from Google search, the advertisement displayed on another link in the linked page will not be applied. Although a lot of people use advertisements to operate websites, ads that are forced to show down will degrade the user experience, so Google will continue to take a strong stance toward "disgusting ads" It is seen as taking it.
