An Email from Yahoo has been sent out to UK advertisers to explain that they are currently testing the forthcoming ‘quality based’ ranking model in some keyword markets. So if you spot your keywords in different positions to those in the bid landscape, this could well be a vertical in the trial.
The full email details -
Yahoo! Search Marketing is constantly striving to improve both the advertiser and customer experience, with the goal of providing the most relevant and targeted listings as users search, click and travel across the Internet.
To accomplish this, we constantly test new implementations and matching technologies. To help ensure we launch our new ranking model successfully we have started running a limited test across our UK advertiser listings in which the display order of Sponsored Search listings in some keyword markets is based on factors other than bid.
In determining listing position, the test will take into account a particular adâ€™s click-through rate, as well as other relevancy factors. The total amount of Sponsored Search traffic that we are providing to you should not change, but due to optimisation of certain keywords you may see traffic volume increase or decrease depending upon the relevancy of your offers and other optimisation factors.
As always, we encourage you to track your results from individual keywords, so that you can manage your bids and creative for maximum return-on-investment.
Our new Sponsored Search system will be rolled out in the UK soon, beginning with advertiser migration later this quarter. We will be contacting you with more specific information as the rollout date approaches.
