🔑 Keyword strategy is four separate jobs: prospecting surfaces new opportunity, negation stops wasted spend, optimization extracts more from what works, and automation scales all three faster than any human team. Miss one phase and the others underperform.
Most advertisers treat keyword strategy as one job. Build all four phases and the account compounds on itself — each week's data making the next week's decisions better. Run only one phase and you're working at a fraction of your potential.
Phase 1 — Prospecting: Find What's Worth Bidding On
Your best keyword source isn't a tool — it's your own search term report. Pull the last 90 days, filter to terms with at least one conversion, and flag anything converting well that isn't already in your account as an exact match. That gap is your prospecting list.
Run phrase and broad match campaigns to generate new query data, then harvest converting terms into exact match campaigns weekly. That loop is the engine behind every high-performing keyword account.
Phase 2 — Negation: Stop the Bleeding
Every dollar on an irrelevant search is a dollar that didn't compete for a relevant one. Pull your search term report weekly, sort by spend, and negate anything above $30 in spend with zero conversions. Do this consistently for 60 days and ACoS or ROAS will shift without touching a single bid.
| Negation Layer | What It Blocks |
| Campaign-level | Irrelevant terms for this specific product |
| Account-level | Terms that are never relevant to your business |
| Cross-campaign | Your own keywords competing across campaigns |
Phase 3 — Optimization: Per-Keyword Math
Every keyword has an implied max CPC based on its conversion rate, order value, and your target margin. Most advertisers never run that math per keyword — they apply a blanket adjustment and call it optimization.
Phase 4 — Automation: Scale What Humans Can't
Manual optimization works at small scale. Once you're managing 500+ keywords across multiple campaigns, bid lag alone costs real money — signals change faster than any human team can respond. Automation executes your strategy faster and more consistently than you can manually.
Start with rule-based automation before full ML bidding — it's easier to audit, override, and learn from. 'If spend exceeds $50 with zero conversions in 7 days, reduce bid by 20%' is easier to trust than a black-box algorithm.

When to Automate vs. Stay Manual
- Under 50 keywords and one campaign: manual wins — human judgment beats any algorithm at small scale
- 50–500 keywords: rule-based automation for bid adjustments, manual for strategy decisions
- 500+ keywords across platforms: full automation is justified — the lag cost of manual exceeds the platform fee
- Practical signal: if weekly optimization takes more than 4 hours and you're still not touching most keywords, it's time to automate
