The inside Adsense blog has tips on how to make your site perform well with AdSense. The AdSense Optimization Team has compiled 3 big points on how to receive more revenue.
- The welcome box ad. Many forums have a message above the fold on their pages welcoming users to the site and encouraging them to register. Placing a large (336×280) or medium (300×250) rectangle next to this message catches usersÃ¢â‚¬â„¢ attention right when they walk through the door (so to speak). By the way, these are our best performing ad units, and may also increase the number of site-targeted ads on your pages.
- The forum post ad. Based on previous testing, integrating ad units into your page content can improve clickthrough rate(CTR). It also provides a better online experience, since your users see relevant ads side by side with normal content. In forums, the highest visibility content is often the first post, so it makes sense to place the ads here. Again, large and medium rectangles are your best bet!
- Blending colors and breaking down borders. Colors are important for making an ad visible to the user, but they should still blend with the design of the site. Removing the borders on your ads helps even more with this concept of blending. DonÃ¢â‚¬â„¢t worry — even with a well-blended implementation, the 'Ads by Google' label keeps your users from confusing ads with content.
Bonus tip: Improve ad relevance with section targeting
With forums, the first post often contains the most relevant content on the page. By using the section targeting feature to emphasize this content, you can potentially increase CTR with better targeted ads. Visit this 'section targeting' link we mention for instructions.
