How To Do Keyword Research For Google Ads

Define clear campaign goals, then brainstorm seed keywords based on your products and audience intent.
Use Google Keyword Planner and tools like Ahrefs or SEMrush to expand ideas. Filter by volume, CPC, competition, and intent.
Organise keywords into tight ad groups, apply match types, add negative keywords, align ads with landing pages, and refine continuously using search term data.
