It is not enough to be an Ad Sense publisher. It is equally important to maximize your earnings from the ads run on your site.
The best way to do so is ensure that your site gets the highest-paying available ads. You can do so if you adopt the following practices:
1. Placement
Place the ad units above the fold, and close to the content. Your site visitors should notice the ad unit without scrolling down.
2. Ad formats
The four top-performing Google ad formats are:
a. Medium rectangle (300×250)
b. Large rectangle (336×280)
c. Leaderboard (728×90)
d. Wide skyscraper (160×600).
Make sure that you select these four formats because most advertisers use these ad sizes to design their campaigns.
3. Ad styles
Don’t make the mistake of choosing either text ads or image ads. Make sure that you choose both. This will give you access to the full ad inventory that is relevant and available for the kind of content run on your site.
Just follow these tips, and you will see your Ad Sense revenue go up.
