Different sites have different optimization needs - where some sites benefit from simple changes like switching to a wider ad format, others see more improvements after changing ad placement or color. Subtle changes can produce significant results. The key is to experiment, measure, and find what works best for your site. That's where channels come in.

Using your channels can help you see a more complete picture of how different types of ads are performing on your site. Do leaderboards perform better than skyscrapers? Or do ads above a navigation bar perform better than ads next to it? Channels help you measure the results. Assign a custom channel to each of the different ad formats running on your site to measure which ones perform best - then you can make changes to maximize your findings.

Here's another tip: include page name, position, ad format, and color in your channel name so you can easily identify what each channel is measuring. 'HomeTopLeaderMotherEarth' tells you the channel is reporting on the leaderboard at the top of the home page with the Mother Earth color palette. These names might look a little funny, but they can help you combine channels into more detailed and valuable reports.
