How Many Keywords should I have per Ad Group?
One Keyword? Fifty Keywords? Twenty Keywords? What is the magic number? Ad Groups are one of the basic components of an AdWords Campaign as they contain Keywords (what words I’m targeting) and Ads (what searchers see). Setting up and organizing Ad Groups is one of the most important factors that leads to success via AdWords and advertisers often wonder how many Keywords they should have in each Ad Group. The answer – hate to disappoint, but there is no magic number. Ad Groups should be organized around granular, thematic Keywords. Let’s dive in.
Organizing the Keywords in an Ad Group to be granular and thematic is going to ensure that I am able to serve relevant Ad Copy to my searchers. Showing relevant Ad Copy to searchers is going to provide a better search experience for users, increase CTR on relevant searches, and hopefully lead to good Quality Scores and ultimately, a strong ROI from AdWords advertising.
Inside of Ad Groups there is not a 1:1 relationship between Keywords and Ads – meaning that if I have multiple Keywords and multiple Ads in my Ad Group, I cannot control what Keyword triggers what Ad to be served. To increase CTR, and make Ads seem relevant to searchers, the Ads should closely be related to search query.
Let’s look at an example:
In the above example, we see nine keywords that are all related to shoes that a consumer can use for sporting activities. Even though these all relate to sports activities, these should be placed into different Ad Groups in order to make the Ad experience more relevant to the searcher. As we look at these keywords, we see themes stand out – basketball, running, and general sports shoes. A way to organize these Keywords into granular, thematic Ad Groups is to create an Ad Group for Basketball Shoes, Running Shoes, and Sport Shoes:
In closing, an easy answer to the question – how many Keywords should I have per Ad Group is: typically you want to have ~5-15, closely related, Keywords per Ad Group. This gives you the ability to scale your Campaigns when organizing, while still being able to serve relevant Ad Copy to searchers.
