Besides the copy and quality content, you can also improve the performance of your AdSense Ads by either making them blend with your website or making them standout. The aim is to make the AdSense Ads more attractive/ appealing to your website visitors and to make them look in-place (not out of place). Google too recognizes this need and hence it provides you with customization options for making the Ads look the way you want them to.
You can make the AdSense Ads suit your website by controlling the shape, size, color and positioning of the Ads. Lets have a brief look at the first two properties i.e. shape and size:
1. Shape of your AdSense Ads: This is one of the most important customizations options that you have at your disposable. You can make your selection from a number of Ad formats that Google makes available to you. These include skyscrapers, single ad blocks and banners. Just check the suitability of the shape with respect to the webpage where you wish to include the AdSense Ad.
2. Size of your AdSense Ads: Again, you can use AdSense Ads of various sizes. The size is important not only for making the Ads look suited to your website but also for determining the number of Ads that can be displayed on the webpage by the Google AdSense program. A large size generally means that more Ads can be displayed on the page (and hence presents the opportunity for earning more revenue with increased impressions).
