There are a couple of Google AdSense updates you'll want to know about. First up, AdSense is getting Promoted Videos from YouTube. These video ad units will contain a thumbnail image plus three lines of text. They're available in the following formats:
- 300x250 Medium Rectangle
- 336x280 Large Rectangle
- 728x90 Leaderboard
- 250x250 Square
- 200x200 Small Square
Next up, AdSense is launching View-through conversion reporting. The feature shows conversions for ads that were seen but not clicked on in a 30-day window. For example, if a visitor sees your display ad but doesn't click - but then goes to your site and performs one of your conversion actions (purchase, signup, etc) within 30 days, that will show up on the report.
View-through reporting is tracked through the AdSense cookies and is only for display ads - not search or text ads. AdSense Conversion Tracking must be installed in order to use View-through reporting.
