Be aware:
When auditing your campaigns, if you allow the platform to display the default 10 keywords per page, you'll likely miss data.
An example scenario:
The macro view of a campaign shows $3.99 in sales. You select "Targeting" to audit the keywords, and then sort by clicks. You page through your keywords, 10 at a time (the platform's default setting), until you reach those keywords that received zero clicks. You did not see your $3.99 sale. Confused, you sort by sales. Sure enough, there's the $3.99 sale. You can see the keyword responsible along with the number of clicks.
You sort by clicks again and page through your keywords, confident you missed something on the first go. Lo and behold, you reach the keywords that received zero clicks with no sign of the $3.99 sale. Certain you need more caffeine, you sort again by sales to look for the $3.99 sale you saw a moment ago. And there it is, right at the top.
While auditing campaigns for a single book this morning, I came across this problem more than a dozen times.
I've been changing the default setting from "10" to "100." It's not a solution, but a reasonable workaround until the dust settles on this platform update.
