Many advertisers using Google AdWords have been very affected recently by this. According to Google's new quality requirements for the AdWords Landing page (Landing page), many businesses that used to bid for advertising at a lower price have found that they now have to pay several times the price to get the ads up front. The reason is that their advertising landing page quality is relatively low, which includes content is not rich, the site has no contact information, full of affiliates links, dedicated to the site for AdSense and so on.

It seems that Google is in the overall struggle against the quality of the site, not only in the search rankings, but also in the AdWords want to eliminate the quality of the Web page.
