Hello Ulfa, Thank you for taking the time to contact Google AdSense. I'll be happy to answer your questions below. 1. If I understand correctly, you have a free web hosting company and want to know if you can put forced ads on your users' pages. If a website is in compliance with our program policies (http://www.google.com/adsense/policies ) and the user has given you permission to display ads on their site, you may place your ad code along with their ad code on the same page. You will, however, need to contact the user or owner of the website to obtain permission to display ads on their website. Please keep in mind that a maximum of three regular ad units and one link unit may be placed on one web page. In addition, please be aware that every publisher is responsible for the content of a website on which their ad code is placed. If a website is found in violation of our program policies, we will notify any publisher(s) whose ad code is on the website, and ask you to remove the Google code from that page. 2. In addition, we understand your concern regarding invalid clicks. In order to prevent abuse of the AdSense program, Google utilizes both automated systems and human reviews to monitor clicks on the ads. Google's technology analyzes clicks to determine whether they fit a pattern of invalid use intended to artificially drive up an advertiser's clicks or a publisher's earnings. A good way to ensure that you do not create invalid clicks is by reviewing and remaining in compliance with our Terms and Conditions and program policies: https://www.google.com/adsense/terms https://www.google.com/adsense/policies In addition, you can review your site's traffic logs for suspicious activity and notify us with any findings. This information can help us in resolving any issues, although as outlined in our Terms and Conditions, Google will use its sole discretion when determining instances of invalid clicks.
