As a result of these vital differences in searcher behavior, I always, always, always recommend segmenting out my traffic in all my pay per click campaigns and ensure that I am separating and differentiating my campaigns by device. I also separate out different geo-targeted areas into different ad groups or campaigns depending on my goals – ad copy that works in New York City may not work in Knoxville. I also segment out display network and content network settings. There are other possibilities for segmentation, but these are absolute necessities.
Why have so many different campaigns (or ad groups) even though they’re all being sent to the same web page? Because different platforms, different devices, and different locations use search queries and respond to ad copy in different ways. By using proper segmentation, you are able to individually optimize each campaign and ensure it’s optimal performance. Separating each of the constituent platforms allows you to improve the overall account performance, improving click through rates and quality score and lowering cost per click. What other ways can you segment a campaign for testing and optimization purposes?
