Rotated or Optimized ad serving, that is the question
Tuesday, December 16th, 2008 - Posted by Aaron Weiner
I recently noticed an interesting recommendation on the AdWords campaign summary page. From time to time Google will make recommendations such as increasing your budget or how they can help with optimizing your campaigns.
Today I noticed a new recommendation titled, “Increase traffic by showing your best ad most often“. I have my campaigns set to “Rotate Ad Serving” and they are recommending that I change this to “Optimize Ad Serving“. To most AdWords users, this probably sounds like a good idea, however it is not.
Take a look at Google’s definition for optimized ad serving:
“Optimize (default): Optimized ad serving delivers ads with higher clickthrough rates (CTRs) into the ad auction more often than other ads in the ad group. These higher-quality ads gain more impressions than other ads in the ad group, resulting in higher ad served percentages. By using this ad serving option, your ad group will likely receive more impressions and clicks overall, since higher-quality ads attain better positions and attract more user attention“.
If you are only interested in clicks and you do not care how they actually perform once they arrive on your website, then by all means play along with Google’s recommendation. If, however, you prefer to receive quality, targeted traffic which performs well on your website, the ad with the highest click-through rate might not be your best performing ad.
What is good for Google might not be good for you. High CTR is great for Google and it may be good for you, however there are situations where the ad with the lowest CTR actually performs best from your perspective. Once the visitor arrives on your website, do they leave immediately or do they stay and perform what you consider to be a conversion? CTR has nothing to do with what people are doing once they arrive on your website.
“Rotate Ad Serving” allows you to monitor and track ad performance by correctly identifying which ad actually performs best for you and not just Google.
Never allow your AdWords account to run on cruse control.
