KeywordSearch assembles ad audiences for Google and YouTube out of keyword and channel research. Audience building on those platforms is usually done by intuition, picking interest categories that sound right, and the results are correspondingly uneven.
Working from keyword data instead means the audience is derived from what people actually search and watch. It also covers keyword research for growing a YouTube channel organically, which uses the same underlying signal as the paid side.
There is a trial. The output still needs a media buyer’s judgement before spend goes behind it, it is limited to the Google and YouTube ecosystem, and pricing tiers are not detailed on the homepage.
