The two methods of AdSense cheating

&http://www.aliyun.com/zixun/aggregation/37954.html ">NBSP; As a publisher forum AdSense Board Moderator, I often see a variety of illegal (cheating) site. Earlier in May, Davidyin had introduced a way of cheating.

The case of the way to explain AdSense cheating, it is indeed a more troublesome thing, although there is controversy, but I am happy to analyze some special examples, these methods have been proven to be Google found, so cheaters do not learn.

The two methods of cheating today, in fact, include two cases.
First of all, it placed more than three advertising units on one page, and then artificially influenced the amount of advertising.

In general, if you put the ad unit code directly on a Web page, Google will only display the first three ads, after the code will not display ads. But this cheater, is by the IFRAME to call multiple advertising units, and these advertising units are not directly in the IFRAME, or through a program to manipulate. As a result, over three ad units are displayed on one page.

So how does it affect the display of human beings?
Just now I mentioned this IFrame, and mentioned a program, what program I do not speak, the impact of display volume, is through the IFRAME, its iframe has such a:
<meta http-equiv= "REFRESH" content= "/>"
This is clear, is a period of time to refresh the IFRAME, so that the display of invalid advertising will increase significantly, this part is obviously a serious violation, it is the refresh label is directly placed in the IFRAME, with some sites because of special needs and placed in the page, is completely different situation.

Here I checked the AdSense help file, in the English version of the AdSense help, there is pointed out that if the page contains a refresh tag, will cause the emergence of public service ads. (This note only in the english-us version), some friends of the site if the long-term display of public service ads, please check if this is the situation.

Finally very difficult to put today's case finished, because can not speak too specific, but also the wrong place to point out, it is not so easy, but as a research, I will in the future when convenient, introduce other irregularities.
