Multiple ad units can help optimise your performance by leveraging our large inventory of ads. Provided you don't place more ads than content on your pages, you can put a combination of ad units and/or search boxes on each page of your site. See our inventory value policy for more information. Remember that the best way to measure the effect of multiple ad units is to examine the impact on your overall earnings. Multiple ad units may prove particularly successful for the following pages:
- Pages with lots of text, requiring users to scroll down the page.
- Forum or message board pages, particularly within threads.
- Pages where only smaller ad formats (such as the 125 x 125 button) will fit.
