Keyword Research
Keyword research is the price-of-admission category for any SEO agency. Pick one tool here, get fast at it, and move on.
Keyword research is the foundation of every SEO deliverable — content briefs, competitor audits, link gap analysis, opportunity sizing for client pitches. Get this category right and most of the rest of your stack becomes optional.
What to buy
The honest answer for 95% of small agencies: Ahrefs or Semrush, pick one. The data difference at small-agency scale is rounding error; the UX difference is what you’ll feel daily. See the Ahrefs vs Semrush comparison for the actual breakdown by deliverable type.
If budget is the constraint, see the alternatives lists below — there are credible cheaper options, but they make trade-offs that matter for some workflows and not others.
Where this fits in the stack
Keyword research is part of the core four — the first tool every small agency buys. It also feeds:
- Content optimization — your keyword tool finds the queries; the content tool tells you how to rank for them
- Link building — backlink data lives in the same product, no need for a separate tool
- Rank tracking — both Ahrefs and Semrush bundle decent trackers
