New Ranking Model Launches Today, February 5, 2007
We're excited to announce that the new ranking model has launched today, February 5, 2007, in our U.S. market. The new ranking model is designed to improve user results through higher quality search ads. When users engage with these higher quality search ads, advertisers will receive more interested, valuable potential customers, helping to drive better results for your business.
As we previously announced, both bid amount and ad quality
now determine an ad's rank in search results.
Your bid is the maximum amount that you're willing to pay when your ad is clicked. You will never be charged more than this amount.
Your ad's quality is determined by:
The ad's historical performancedetermined by its click-through rate relative to its position on the page.
The ad's expected performance, relative to competing ads displayed at the same timedetermined by various relevance factors considered by Yahoo!'s ranking algorithms.
You can gain an understanding of an ad's quality by looking at its quality index, which will be available to you once you've upgraded to the new Sponsored Search system.
