Google AdSense is one of the oldest and most-trusted ad networks on the web. The network uses the pay-per-click model of advertising which means that Google pays the publisher of a participating website every time an AdSense ad is clicked.
The Google AdSense service is extremely popular with website owners who want to monetize their site ― some of them even make a living by placing ads on websites. Webmasters must code the site carefully and according to Google's instructions to ensure maximum click-throughs.
Google claims to automatically deliver ads to your site that target your intended audience based on the site's content but in the real world that doesn't always happen. Many AdSense users report Google delivering advertisements that have little or nothing to do with their site's content.
The Death of A Beloved Feature
Some who make the claim of irrelevant ads point to Google's decision to discontinue support for section targeting. According to Google their new technology more accurately matches ads to a site's content and renders the feature obsolete.
A formidable number of webmasters consider section targeting to be at the heart of success with Google AdSense. A site was optimized by adding specific HTML code to both the beginning and end of content that best conveyed the purpose of that site.
In other words, when the Google web crawler indexed a page that was coded in such a way it concentrated only on meaningful content and not surplus information; for instance, comments.
Concentrate On Content
The most important thing to remember is that Google doesn't guarantee that they'll always have relevant ads to display on a participating site. AdSense ad serving depends on many factors, including the content on your site and the availability of relevant ads. In order for Google AdSense to succeed at placing ads on websites that are relevant, owners need to be aware of some rules regarding the content on their sites.
Google doesn't serve ads according to a set of keywords (though they still analyze keywords in the content) or the advertisement categories you choose. They — or rather their crawler — serves ads based on a website's overall content. It's advisable to create and tailor content with this in mind. Google recommends using complete sentences and paragraphs to assist their crawlers.
When a webmaster codes a site with the intent of working with the Google crawler, the ads offered by the Google AdSense service will likely be relevant to that site.
