|How will the new rank model take effect?|
Yahoo rank model

Will it take the current CTR we have since FEB and assign us a rank from that, or will it start over on FEB 5.
Also, a more general question, does your CTR ranking start over every month? How does this work?
Thanks in advance.

Remember that more than click-through rate influences the quality of an ad: The quality of an ad is determined relative to other ads displayed at the same time by both its expected performance going forward and its historical performance. Historical performance data was not purged on February 5, but as time passes, the data generated after the launch of the new ranking model will have the strongest influence on ad quality calculations.
The time it takes to take both expected and historical performance into account to measure ad quality depends on the volume of searches related to a keyword. Keywords with lots of daily searches often generate enough data in a relatively short period of time until historical performance is a stronger factor for ad quality within that marketplace.
And no, the data used to determine ad quality is not “purged” at the beginning of a new month.

How do new ads get any historical data? I added a few ads for expensive, high volume search terms, and then checked the overture bid tool,(before the ability to check bid prices was removed late yesterday) and I was the fourth highest bid. Yet, for this new ad, I am displaying at about result 30, therefore I can't get any traffic to the ad to even generate historical data. Doesn't make much sense. What am I missing? I'm positive my bid price for this new ad/campaign is in the top 5 in price.

YahooSarah - in case you have any pull at Yahoo, your Publisher ad targeting has dropped like a rock since the rollout of Panama.
Just thought you'd want to know in case you can get your guys/girls to improve the relevance of Publisher ads.

To address kdobson99 question -“I can't get any traffic to the ad to even generate historical data.”
Fair point – or so it seems. But if that were the case, then anytime new ads were added to our system, they’d get lost in the shuffle. And that outcome wouldn’t work for any of us ;-)
The important thing to remember is that these days, ad quality is a crucial factor in how an ad is ranked. Not just bid amount. And it’s true: ad quality is based on expected performance and historical performance.
But in the absence of historical performance – i.e., with NEW ads, we use expected performance. And expected performance is all about relevance factors, which we use to assess the likelihood that your new ad will be clicked. To maximize the likelihood that your new ad will be clicked, make your ads as relevant to your keywords as possible.
This page (http://help.yahoo.com/help/l/us/yahoo/ysm/sps/start/overview_qualityindex.html) shows an example of a less relevant and more relevant ad, and it also offers some suggestions for making your ads as relevant as possible.
As impressions and clicks accumulate, your historical performance (click-through rate normalized for position) becomes a stronger factor in determining your ad quality.

What's to prevent someone from simply copying (subtly changing it by using a synonym or two) their competitor's ad that has high position?
After all, the ads can't be very long and duplication can be the only way to go.
