Hi, I need to know something: if I have let's say different pages and all have different content, is it better to create differents ads and place on every page or should I use just one for all pages? If I create multiple, will it display different ads? Thanks
it depends on how the ad network pays. usually with ctr/cpc, you want the ads right next to the main content i believe as thats the spot people pay attention to most on a page. not sure how your site looks or what its about but on mine, i have it so the different ads are placed depending on page/post
you can put single code on any type page, because ads are not included with the code, ads are fetched by code from remote server with relevant to the content. Only the size of ad matter with code not the particular advertiser or ad related to the code. People create different type ads because of its size and visual type not for different advertises or ads.
