As your potential visitors are visiting your site for learning more about the subject you are talking about, they might not be interested on those irrelevant ads, and hence they tend not to click on your AdSense ads since they are non-targeted to your content. Hence, you are losing some potential visitors who may generate few clicks for you. Because of irrelevant ads, you are losing some extra cash. At this moment, what you need is the section targeting which consists of several pieces of HTML tags.Section targeting allows you to suggest a sections of your content that you’d like to emphasize or de-emphasize when matching ads to your site’s content. It will help you to improving your ad targeting and CTR.It's simple. Just add a set of special HTML comment tags to your code which will mark the beginning and end of whichever section you'd like to emphasize or de-emphasize for ad targeting and use it for as many sections of a page as you like.The ads will now be targeted on content between these tags, and if it lacks adequate keywords and content, you may see Public Service Ads.
