Here are the key points:
Step 1: Analyze the pages of your blog or website
Of course, the first step to successful Adsense optimization is to analyze your webpages. Why? Because the form and function of your site will dictate how your audience interacts with ads on it. Ask yourself these questions when deciding where to put ads on your site:
What type of content do you have?
Your content will determine the type of audience you will have. People interact differently on articles, blogs, forums, and video sites, for example -- so think about how people will be interacting on your own site.
Where is visitor attention likely to be focused?
What good are adblocks placed at the very bottom of the page where no one would see them? Put ads to where the action is! Just be careful not to place them where they would only be detrimental to user-experience.
But how can you integrate ads into an area on the webpage without getting in the way of your users? Let this heatmap guide you: Google Adsense Heatmap
Think about your readers but also be mindful of your potential advertisers. If you can make your site more appealing to advertisers, while keeping the above tips in mind, you're more likely to to attract advertisers who'd be willing to put targeted ads on your site.
Step 2: Set up custom channels
This is something that most Adsense publishers forget to do: Setting up custom channels for ad units.
Custom channels will help you find out how different ad units on your site are performing based on a number of variables, like size, placement and even color. Create a channel for individual ad units and categorize them to see how well or how bad they're performing. For example, you can track your leaderboard and medium rectangle to see which performs better, and use this information to choose which one to use on your page. The best part: Custom channels will likewise allow you to track the success of your adsense optimizations.
Step 3: Optimize every Adsense unit's design and placement
The next step is to choose the right color, position, and size of your ad units and optimize them for user experience, advertiser needs, and performance. Google Adsense suggests that you use medium rectangle (300 x 250), wide skyscraper (160 x 600), and the leaderboard (728 x 90) on your site as they tend to perform best. Image optimized units receive rich media and video ads, which tend to be favored by readers and as such, perform well in terms of click-through-ratio. Keep in mind that you need to implement your ads in a consistent manner and in a way that is desirable to advertisers.
Use colors effectively. Blend ads in, but not too much that users don't see them. Borderless ads tend to work well, as does highlighting the link and URL. Test different colors and placements, and then keep the changes that perform best. - via
Step 4: Maximize revenue by placing multiple ad units
You can use up to three ad blocks, three link units and two search bars on every page of your site. Feel free to wield all these for maximum revenue but keep the above-mentioned tips in mind e.g. be mindful of user-experience, use custom channels etc.
Step 5: Track and measure results. Continue best practices.
The last step is to understand and measure the results of your optimizations. Here, use the custom channels you set-up earlier and even Google Analytics, which you can hook up with your Adsense account, to generate reports on your different ad units. See which adblocks are performing best, which colors give a higher CTR and which pages on your site deliver better performing ads. Use the info to gain even better results in the future.
There you go! :) I hope you find this useful.
