How to Write a Google Ads Campaign Brief That Keeps Ad Groups Tightly Focused

Many self-managed Google Ads campaigns end up with bloated ad groups, mediocre Quality Score, and unclear ad performance, usually because they were built without a proper brief. The author argues the brief should be written before touching the interface and should define one business goal per campaign, group buyers by search intent, map tight keyword themes to each segment, pair each theme with a dedicated landing page, and set a negative keyword list before launch. A SaaS example contrasts a weak single-audience approach with a segmented one that splits small-team buyers, competitor switchers, and bottom-of-funnel shoppers. The article also lists common mistakes, such as relying on keyword tools alone, running one ad group for a whole product, and writing the brief after launch. The piece is written by a team behind an AI tool that generates campaign briefs.
