At What Level Should You Add Negative Keywords?

The Power of “No” in Paid Search

Most marketers focus on what they want to bid on. But in a world where “Exact Match” isn’t strictly exact and Broad Match dominates, what you exclude is often more important than what you target.

Negative keywords are your primary tool for Search Query Sculpting—the process of forcing Google to show your most relevant ad rather than the most convenient one. By applying them at the right level, you don’t just “save money”; you curate a user experience.

Understanding Negative Match Types

Negative match types mirror their positive counterparts—but with one key distinction: they do not account for close variants. If you exclude [Red Hat], you might still show for “Red Hats.”

• Negative Exact — Blocks a specific query only. Use for high-volume terms that are almost right but don’t convert.
• Negative Phrase — Blocks any query containing the specific phrase in order. Ideal for eliminating irrelevant “intent themes.”
• Negative Broad — Blocks the ad if the query contains all your negative terms, regardless of order. Best used with single-word terms (like free or jobs) to efficiently sweep out irrelevant traffic. Use cautiously—it can unintentionally block valuable searches.

Also worth noting: negative match types are independent of your positive keywords. You can run broad match keywords while still applying exact match negatives to control specific queries.

The Hierarchy of Exclusion

Negative keywords can be applied at three levels: ad group, campaign, and account. Each serves a different strategic purpose.

1. Ad Group Level — The Precision Layer

This is your most granular level of control. Use ad group negatives for internal sculpting—ensuring queries land in the specific ad group designed for them and preventing keyword cannibalization.

Example: If you have separate ad groups for “Leather Boots” and “Discount Leather Boots,” add discount and cheap as phrase match negatives in your premium ad group. You force the bargain hunter toward the discount ad (improving CTR) and protect your luxury messaging for the high-end shopper.

2. Campaign Level — The Intent Layer

This is where search query sculpting becomes especially powerful.

Example: If you offer both Courses and Degrees, exclude courses from your Degrees campaign to keep intent clean and messaging aligned.

3. Account Level — The Brand Safety Layer

Account-level negatives are for terms that are universally irrelevant to your business model—things you never want to show for, regardless of campaign or ad group.

Example: If you sell musical instruments, you might exclude:

• “lessons”
• “free”
• “DIY”

These are queries that don’t align with your business model, regardless of campaign or ad group.

Managing at Scale: Negative Keyword Lists

You don’t have to manage negatives one by one. Negative keyword lists allow you to apply a shared set of exclusions across multiple campaigns—and they quickly become essential at scale.

Instead of manually adding the same 50 “junk” terms to every new campaign, create a Master List (e.g., “Non-Commercial Intent”) and simply attach it when launching a new campaign.

Why this matters:

• Universal protection — Add a term once, and it applies everywhere the list is linked.
• Prevents gaps — Eliminates the common error where a term is blocked in Campaign A but accidentally starts spending in Campaign B.
• Team efficiency — Ensures your team follows a centralized exclusion strategy rather than making one-off decisions.

A Strategy-First Workflow

Managing negatives shouldn’t be a reactive chore—it should be a proactive strategy.

1. Pre-launch: Run a keyword report and build a “Master List” of universal negatives before the campaign goes live.
2. Weekly: Run a Search Query Report (SQR). If a winning query is matching to the wrong campaign, don’t just let it run—sculpt it into its proper home using negatives.
3. Monthly: Audit your negative lists to ensure you haven’t inadvertently blocked new, high-performing trends.

Efficiency isn’t just about spending less—it’s about spending better. This is what separates a campaign that runs from one that scales.
