The Show fewer ads lab lowers the number of ads shown to users by at least 10 percent. Publishers can, in turn, expect to see a drop in revenue, but a drop Google estimates will be “negligible,” or less than one percent of revenue, because the focus is on eliminating ads that are likely to be deemed of lower value to a publisher’s visitors.
Inline ads are dynamically inserted mobile website ads sized 320×100. They appear as users scroll down a page and don’t require programming on the publishers’ end. AdSense publishers will find Labs under the Optimization tab. When more tests become available, Google will add them to Labs.
