(A) Keyword Optimization
(B) Ad Testing
(C) Audience Targeting
(D) Blog Writing
(E) All of the above
All three are important tactics for optimizing PPC ads. Keyword reports give you data on which keywords are getting the most clicks and conversion. Which keywords don’t get clicks and which keywords get a lot of clicks but not many conversions. You can use this data to filter out your best performing keywords and excluding out the non-performing ones.
You should test a lot of ads and check the ad reports. The ad reports tell you which ads inside a specific ad group are getting clicks and conversions and which ads don’t get clicks. You can use this data to increase the bid on ads that are doing well and pause ads that aren’t doing well.
You can use Audience targeting for creating remarketing lists using Custom audiences and In-market audiences. This will give you even more conversions.
