How to Fix Broad Match Keywords That Are Wasting Spend
When Broad Match is used incorrectly, it expands far beyond your intended audience—matching to irrelevant searches, research intent, job seekers, competitors, and low-converting queries. Broad Match can work, but only when tightly controlled.
1. Audit All Broad Match Keywords
Start with a full inventory.
Fix:
- Export all keywords
- Filter by Match type = Broad
- Flag keywords that:
- Spend heavily with low or no conversions
- Match to irrelevant queries
- Are overly generic (e.g., “marketing,” “software,” “lawyer”)
Broad Match should never be used for vague, top-level keywords.
2. Move Generic Broad Keywords to Phrase or Exact
If a Broad keyword represents a core service, control it.
Examples:
- ❌ Broad: plumber
- ✅ Phrase: “plumber near me”
- ✅ Exact: [emergency plumber]
Fix:
- Convert high-volume Broad keywords to phrase or exact
- Use exact match for highest intent
- Use phrase match for mid-intent searches
3. Build (or Strengthen) Negative Keyword Lists
Broad Match without negatives is a guaranteed money leak.
Add negatives for:
- Job seekers (“jobs,” “careers,” “salary”)
- DIY intent (“how to,” “DIY,” “tutorial,” “free”)
- Low-value intent (“cheap,” “free,” “discount”)
- Wrong audience (“student,” “training,” “certification”)
- Wrong industries or competitors
- Locations you don’t serve
Fix:
- Create structured negative lists by theme
- Apply lists across campaigns
- Add new negatives weekly from Search Terms
4. Use Broad Match Only in the Right Conditions
Broad Match only works with strong machine-learning signals.
Only use Broad if:
- ✔ Smart Bidding is active (Max Conversions, tCPA, tROAS)
- ✔ Conversion tracking is reliable
- ✔ Negative keyword framework is strong
- ✔ Keyword already converts in phrase/exact
- ✔ You’re scaling volume—not discovering basics
5. Test Broad Match in Dedicated Campaigns
Mixing Broad with Exact/Phrase hides problems.
Fix:
- Create a separate Broad Match testing campaign
- Use lower initial budgets
- Apply strict negative lists
- Monitor search terms daily
- Use tight tCPA or tROAS targets
6. Mimic Broad Match Modifier (Controlled Broad)
While BMM is gone, you can still simulate control.
Fix:
- Use multi-word phrase match keywords
- Add restrictive negatives
- Keep the core intent narrow
Example:
Instead of Broad: plumbing
Use Phrase: “plumbing services”
Add negatives: how to, DIY, jobs, training, school, supplies
7. Review Search Terms Daily (Initially)
This is the fastest way to regain control.
Fix:
- Add negatives aggressively
- Promote high-quality queries to exact match
- Pause Broad keywords driving junk traffic
Performance often improves immediately.
8. Segment Broad Match by Intent
Advanced accounts separate Broad by intent level.
Example:
- High-intent Broad (already proven)
- Mid-intent Broad (related services)
- Exploratory Broad (new themes)
Fix:
- Bid highest on high-intent
- Bid lowest on exploratory
- Keep them in separate campaigns
9. Improve Ad and Landing Page Relevance
Weak relevance confuses Google’s matching.
Fix:
- Add keyword clusters to landing pages
- Use keyword-rich headlines in ads
- Create intent-specific landing pages
- Separate pages for different services/themes
10. Cap Broad Match at 10–20% of Keywords
Best practice mix:
- 70–90% Exact + Phrase
- 10–20% Broad (purposeful, monitored)
Broad Match is a scaling lever—not a foundation.
