Negative Keywords

Chapter Objective

By the end of this chapter, you will have:

• A complete negative keyword framework
• Clear negative keyword buckets (not random lists)
• Buying-Moment-specific exclusions
• A repeatable process to protect CPL and CPA long-term

This chapter is not optimization. It is defense.

Why Negative Keywords Decide Survival

Google's job is to:

• maximize clicks
• maximize coverage
• explore edges

Your job is to:

• protect intent
• block waste
• preserve learning quality

If you don't actively tell Google who you don't want, it will happily spend your money finding them.

The Biggest Misconception About Negatives

Most advertisers think negatives are:

• a cleanup step
• something you do "later"
• optional if keywords are tight

That is false.

Negative keywords define your audience as much as your keywords do.

Especially on small budgets.

The Only Way to Think About Negatives

Negative keywords are not random words. They are intent blockers.

Each negative exists to block:

• a type of searcher
• a type of mindset
• a type of Buying Moment you do NOT want

The Five Mandatory Negative Keyword Buckets

Every Search campaign must have all five buckets.

If one is missing, budget leaks.

BUCKET 1 — RESEARCH / EDUCATION

People Who Want Information, Not Help

What This Bucket Blocks

Searchers who want:

• explanations
• learning
• guides
• definitions
• theory

These people are not bad — they're just not buying now.

Common Research Negatives

• how to
• what is
• guide
• tutorial
• pdf
• manual
• instructions
• diagram
• youtube
• reddit
• wiki

Add these as phrase or exact match negatives at the campaign level.

When NOT to Use This Bucket

If your Tier 3 (questions) keywords are decision-adjacent, not educational.

Example allowed:

• "how long to redo failed EV charger install"

Example blocked:

• "how does an EV charger work"

Context matters.

BUCKET 2 — DIY / SELF-SERVICE

People Trying to Do It Themselves

DIY traffic is one of the biggest budget killers.

Common DIY Negatives

• diy
• do it yourself
• kit
• parts
• supplies
• tools
• wiring diagram
• home depot
• lowes
• amazon

Add as campaign-level phrase match negatives.

If someone wants parts, they do not want your service.

BUCKET 3 — JOBS / CAREERS

People Looking for Work, Not Help

This bucket is often missed — and expensive.

Common Jobs Negatives

• jobs
• hiring
• careers
• salary
• pay
• apprenticeship
• training
• certification
• license exam

Add these as campaign-level exact and phrase match negatives.

BUCKET 4 — PRICE SHOPPERS / LOW INTENT

People Optimizing for Cheap, Not Outcomes

Not all price sensitivity is bad — but extreme price intent often signals poor fit.

Common Price Negatives

• cheap
• free
• lowest price
• discount
• coupon
• promo
• costco

Use carefully.

For small budgets:

• exclude extreme bargain hunters
• allow normal pricing questions

BUCKET 5 — WRONG BUYER / WRONG USE CASE

People Who Are Not Your Category Buyer

This bucket is Buying-Moment-specific.

Examples (EV Charger)

• commercial fleet (if you serve residential only)
• apartment tenants (if only owners hire you)
• electric scooter
• ebike charger
• phone charger

These must be added at the ad group level when relevant.

Step 13A — Build Global Negatives First (Required)

Before launching anything:

Create a campaign-level negative list with:

• Research bucket
• DIY bucket
• Jobs bucket
• Extreme price bucket

This list applies to every ad group.

Step 13B — Build Buying Moment-Specific Negatives

Now, for each Buying Moment ad group, ask:

"Who might accidentally match these keywords that I do NOT want?"

Example:

• inspection keywords → block students
• emergency keywords → block advice-seekers
• repair keywords → block product-only searches

Add these negatives at the ad group level.

Step 13C — Use the Search Terms Report (Correctly)

This is where most people panic.

Rules for Search Terms Review

• Do not review daily
• Do not add negatives emotionally
• Do not block learning too early

Proper Review Cadence

• First review: after 30–50 clicks
• Then weekly
• Look for patterns, not one-offs

What to Negative

Negative a term if it:

• shows wrong intent
• repeats across searches
• belongs clearly to a blocked bucket

Do not negative:

• rare phrasing
• unclear intent without repetition
• anything matching a Buying Moment

Step 13D — Use AI to Identify Hidden Negative Themes

AI helps spot patterns humans miss.

AI Prompt: Negative Theme Detection

Review these search terms: [PASTE SEARCH TERMS REPORT]

Group them into:

• clear buying intent
• research intent
• DIY intent
• wrong buyer intent
• unclear (do not block yet)

Explain why.

Use AI to classify, not decide.

Required Output (Hard Gate)

You must finish this chapter with:

• One global negative keyword list
• At least one Buying-Moment-specific negative list
• Clear separation between campaign vs ad group negatives
• A documented review cadence

If you skip this, stop now.

Common Failure Patterns

If negatives are weak:

• CPL creeps up quietly
• lead quality degrades
• Google "learns" the wrong audience
• optimization becomes reactionary

Negatives prevent slow death, not sudden failure.
