I would like to submit my feedback that the new ad rotate setting is going to be the most detrimental “upgrade” to AdWords ever rolled out. I have never been so mad about anything in my six years as a search marketer. 30 days is not enough time for a large number of ad groups to determine what ad should be a “winner.” There is a fine line to walk between getting a good click through and a good conversion rate. None of it is as easy as simply selecting “optimize for clicks” or “optimize for conversions.” Take, for example this ad group:
Guess which ad is going to win eventually under the new “ad rotate” feature? The ad that is performing the worst in terms of conversion rate (the first ad). But, we don’t want to simply optimize for conversions either. These conversion rates are too low to make sufficient decisions based entirely off of conversion rate — 30 days is not enough time to make good decisions. A given ad group could have four instances of the same exact ad, and conversion rates over a 30 day period could that look like they are four completely different ads. With the example above, the third ad is most likely to produce the most gross profit based purely off of these numbers, but these numbers are no good to be making decisions with given the nature of the user experience that leads to conversions. More time is required to make a good decision, dependent upon the amount of traffic a given ad group gets.
Another example:
Why must advertisers be forced to choose a winner here? These ads all perform, more or less, commensurately. Perhaps, over time, a real winner will be revealed, but for the past thirty days, the click through and conversion rates for these ads have been fairly similar. Why must Google force a winner down every advertiser’s throat? Why can’t the advertiser be allowed to take the time necessary to make the appropriate decisions.
Having ads that are supposed to “rotate” optimize for click through rate is the opposite of an innovation. Optimizing for click through rate does not take conversion rate into consideration, and many advertisers purposefully test ads with lower click through rates in an effort to increase conversion rates. Likewise, simply optimizing ad rotation for conversion rate does not properly take into account a number of factors, including click through rate, and the difference between the click through rate metric (which occurs on the Search Engine Results Page) and the conversion rate metric (website user experience). Sophisticated advertisers have the ability and the know-how to make these decisions for themselves.

Why would Google intentionally anger so many advertisers? If Google wants to make this change to the ad rotate feature, add it as a fourth ad rotation option. There is more to improving user experience than simply looking at either click through rates or conversion rates. I urge Google to roll back this change, or alter it to become a fourth ad rotation option.
