So what does it do eCPM? AdSense in helping document is described in: Effective CPM (Effective CPM) - for every thousand times the cost of display. From the publisher's perspective, CPM is a very useful comparison of different channels and advertising revenue plan. It is divided by the total income of a few thousand impressions calculated. For example, if the publishers are 45,000 impressions, the revenue for the US $ 180, while CPM is equivalent US $ 180/45, or US $ 4.00. It is important that, eCPM low channel would affect the entire account, which eventually led to the entire site low eCPM. Therefore, as long as an increase in overall eCPM value, then the Adsense's overall revenues will be correspondingly improved. So how to improve the page eCPM, is the first prerequisite for the page flow of the need for adequate and sufficient clicks, if the number of clicks per day is less than 100, there is no need to control what eCPM, the first to find ways to improve site traffic, if Web site traffic has been good, but the low eCPM values, we can plan does not violate Adsense policy, the adoption of the following methods to improve the site eCPM. 1, to improve the overall Web site traffic Including the use of methods such as SEO optimization to improve the overall Web site traffic and PageRank, so that site more friendly for search engines. 2, to improve site click-through rate Display advertising is not the more the better, click on the ads if the low rate of frequency shows that the effect of the contrary, will reduce the site's eCPM, that kind of advertising is not as good as deleted. Adsense click-through rate to improve the basic method is to adjust the location of advertising and advertising and color, the general左上部page and the top of the highest click-through rate, and the way the use of the rectangular box, the contents of ads and articles together will increase the advertising The click-through rate (although I personally do not like the way). The adjustment of color is the background and text color ads will be adjusted and its overall style of the same Web site, you can improve the click-through rate. Another increase the click-through rate is to control advertising content, because users will only click on ads of interest, so the competition through the Adsense ads will then refuse ads join a blacklist of domain names, such as low click-through rate of advertising is not will be shown. This kind of garbage is easy to find advertisers, all of MFA (Made for AdSense) sites should be added to the blacklist, such as the FireFox browser, such as the promotion of the site. 3, delete ads and low click-through rate Analysis of all the Adsense channels, the site is very low click-through rate of all the ads are deleted, will be lower eCPM to delete all the channels. To remove these ads, although the overall number of ads displayed will be reduced, but overall you will be a substantial increase in Adsense income.
