9. Place ads only on Content Pages. Advertisers pay only for content based ads. Content drives relevant ads. Although you might manage some clicks from error, login, registration, “thank you” or welcome pages, parking pages or pop ups, it will get you out of the program.
10. Do not mask ad elements. Alteration of colours and border is a facility to blend or contrast ads as per your site requirements. I have seen many sites where the url part is of the same colour as the background. While blending the ad with your site is a good idea, hiding relevant components of the ads is not allowed. Also do not block the visibility of ads by overlapping images, pop ups, tables etc.
11. Do not send your ads by email. Html formatted emails look good and allow placement of these javascript ads. But it is not allowed as per TOS. You do not want impressions registering on their logs from any email even once. They are watching!
