You’re welcome to promote your site in any manner that complies with our program policies. However, AdSense publishers are ultimately responsible for the traffic to their ads. So if you choose to partner with a third-party service to increase traffic to your site, it’s critical that you monitor your reports closely to gauge the impact that each source has on your ad traffic.
There are many services out there that can increase traffic to your site, including pay-per-click solutions to connect advertisers and publishers, as well as search engines and directory sites. However, we’ve found that some of these services actually send artificial traffic to websites, despite their appearance. To deliver the traffic levels that their customers expect, these services often generate clicks and impressions using click bots, or by providing users incentives to visit sites or click on ads. For this reason, we strongly urge you to use caution when partnering with third-party traffic services.
If you need help logging the traffic on your site to determine the source of your visitors, we recommend using Google Analytics. You can also integrate your AdSense account with Analytics to get more insight into how to tailor your content and ads to your site's users.
Lastly, we understand that you may want more information about traffic services that we’ve found to send invalid traffic. However, because we need to maintain the effectiveness of our detection system, and because revealing the names of these services could create legal complications, we’re not able to provide these details.
