This is the final video installment in our three-part series on Optimisation Essentials for AdSense for content. We've covered the best-performing ad unit sizes and taken a look at how to design your ad units for good-looking ads. However, even if you have large, well-designed ad units, they won't perform for you unless your users can see them!

Today, to help its video content partners earn more money, YouTube will begin running overlay ads in YouTube partner videos embedded on other websites. To date, YouTube has only run ads against partner videos on YouTube itself, and with people viewing millions of embedded YouTube videos every day, this meant that partners were not generating revenue from their views outside YouTube.com. But now, YouTube partners will be able to capitalize on their popularity across the internet and generate revenue from their content no matter where their video lives.

The AdSensePro team would like to cordially invite you to the opening of our new English AdSense Help Forum.

Here in AdSense, we’re big on data. From spreadsheets and graphs to weekly reports and metrics, we constantly turn to numbers when running our business. In a similar vein, we've heard your requests for more data to help you run your AdSense websites, which is why we’re excited to announce the integration of one of our personal favorite reporting tools, Google Analytics, with AdSense. We're gradually rolling out this functionality to publishers, and you'll see an invitation link at the top of your 'Overview' and 'Advanced Reports' pages when it's been enabled for your account.

Do you develop or publish web-based games?

As a beta user of AdSense for Games, you can display video ads, image ads, or text ads within your online games to earn revenue. You'll be able to show these ads in placements you define, such as interstitial frames before a game, after a level change, or when a game is over.

AdSense for content is the bread and butter of many of our publishers, and we often receive requests to recommend strategies to improve AdSense performance on publisher sites.

In response, we're releasing a three-part video series that demonstrates, in plain English, our top tips for increasing your AdSense earnings.
