Consumers' preferred search portal has helped marketers make money from paid search campaigns, and now it may become an important platform for video advertisements. The latest online video rankings from comScore show that Google is holding strong as the leading online video property, and video ad reach on the platform is steadily growing.

ComScore's data shows that Google sites took the lead among online video audiences. Google garnered 143.2 million unique viewers in July 2010, and its sites accounted for 1.9 billion video viewing sessions. Google sites also had the highest viewer engagement, averaging 4.7 hours per viewer. This shows an increase over June 2010, when viewers averaged 4.3 hours of video watching on the sites.

Google also gained ground in video ad viewership last month. Google properties jumped from sixth to fifth place in terms of ads viewed. Google sites delivered 200 million video ads in June, and they served consumers 219 million videos in July. While Hulu maintained its first-place position, gaining ad viewers in July, and Microsoft sites continued to rank fourth in video ad delivery, other properties ahead of Google – including Tremor Video Network and Bright Roll Video Network – declined in the number of ads distributed in July.
