1. ROI Impact of Internet Advertising is Greater Than Previously Thought According to the OAR, on average, there are 33% more conversion events (such as purchases, registrations, etc.) from users who only viewed an ad, but did not click, than from users who clicked on an ad. "With AdKnowledge eAnalytics, we've been measuring conversions from impressions for our clients to track purchasers who convert from only seeing an online ad," said Steve Findley, V.P. AdKnowledge Analytic Services, the company's data mining and analysis arm. "This data yields two important conclusions. First, the potential ROI impact of Internet advertising is much greater than previously thought. Second, advertisers that focus only on clicks or even post-click conversions may miss vitally important effects of their advertising campaigns," he explained.
2. Ad Conversion Events Peak Mid-Week OAR statistics show that ad deliveries, click throughs and customer conversion events peak during the lunch hour mid-week, with the lowest activity taking place on weekends. In the first quarter, AdKnowledge eAnalytics data shows 38% more activity taking place at noon Mondays through Wednesdays, than noon on Saturdays.
3. Web Advertising Growth Continues to Rise According to AdKnowledge's OAR, the number of ad-supported sites and networks continues to grow rapidly. In the first quarter, the number of sites and networks grew by 723 - an increase of 22%.
4. CPMs Continue To Stabilize The OAR also shows online advertising rates continued to stabilize even as availability of sites continues to grow. Average cost-per-thousand impressions (CPM) rates remained nearly the same, falling only .48% in the first quarter of 2000 to $33.59 from the fourth quarter of 1999 rate of $33.75.
