As a publisher, you are likely to have this question — how many ads should you run on a page? And, most importantly, does having more ads result in lesser ad revenue?
To answer your first question, there’s no hard limit on the number of ads per page. Google previously had a limit of 3 AdSense display units and 5 AdX display units per page. But the limit has been removed. That doesn’t mean you can add as many ads as you would like to. Why?
Because it can hurt your revenue. So, the answer to your second question is, yes, having more ads can result in lesser revenue.
Some of the reasons:
– Having too many ads means it’s difficult to ensure better viewability and CTR for the ads. Thus, in turn, can lower the eCPM.
– Users might be overwhelmed with the ads and bounce off the page soon. Again, this can lower your revenue per session drastically.
– Some exchanges and networks can stop bidding for your impressions when they realize the inventory isn’t performing as expected.
What’s the solution?
– Try lazy loading ads.
– If you have a long-form content, try splitting the content into multiple parts and let user navigate through the posts with a call to action button. And, keep 3 to 5 ads per page.
– Try dynamically rendering the ads rather than displaying all ads as soon as the user loads the page.
– Experiment with ad refresh. Ad refresh, when done right, can help you maximize revenue per session without hampering the user experience.
