Negative Keyword Neglect: The Easiest Win Most Agencies Ignore
Your search terms report tells you exactly which queries are wasting budget. Yet most accounts have negative keyword lists that haven't been updated in months. This is the single easiest way to improve profitability - and the most commonly neglected.
The Biggest Leak
In every audit we run, search term waste accounts for 15-30% of total spend. Not on terrible keywords - on queries that are close enough to match but far enough from purchase intent to never convert.
"How to clean leather shoes" is not someone buying shoe cleaner. "Cheap alternatives to [your brand]" is not someone buying from you. Yet both queries trigger ads every day in accounts with neglected negative lists. This waste compounds the landing page conversion tax you're already paying.
Why It Gets Neglected
Negative keyword management is unglamorous. It doesn't produce impressive-looking charts. It doesn't demonstrate strategic thinking in a quarterly review. And it requires consistent, repetitive attention.
But if spending 30 minutes per week saves £2,000/month in wasted spend, that's a £96,000/year return on 26 hours of work. No bid strategy change delivers that kind of ROI. This is exactly the kind of work that Smart Bidding makes agencies skip.
High-Waste Patterns
- • Informational queries: "how to," "what is," "DIY," "tutorial" - research intent, not purchase intent
- • Competitor brand terms: Clicking your ad to find competitor information
- • Job-related queries: "careers," "jobs," "salary" for your product category
- • Free/cheap modifiers: "free," "cheap," "budget" - low-value buyers
- • Wrong geography: Queries for locations you don't serve or ship to
- • Wrong product type: Similar-sounding products in different categories
Building Effective Lists
Start with a universal negative list applied across all campaigns: jobs, careers, free, DIY, tutorial, review (unless you want review traffic). Then build campaign-specific lists based on search term analysis.
Sort search terms by cost descending. Focus on high-spend, zero-conversion terms first. Then move to high-spend, low-conversion terms. The 80/20 rule applies: 20% of wasteful terms account for 80% of wasted spend.
Ongoing Maintenance
Set a weekly calendar reminder. Review search terms from the past 7 days. Add negatives. Check for new broad match expansions that are pulling in irrelevant traffic. Document patterns.
If your agency isn't doing this weekly, ask them why. If they can't show you the negative keywords they've added in the last 30 days, that tells you something about the depth of their management. It's one of the clearest signs we flag in how agencies waste your money.
