The Essential Negative Keywords Guide for Google Ad Grants

If there's one optimization that delivers the biggest impact with the least effort in a Google Ad Grant account, it's negative keywords. They're free, they take minutes to add, and they simultaneously protect your CTR compliance, improve your conversion rate, and prevent budget waste.

Yet the majority of Grant accounts we audit have zero negative keywords. None. Every irrelevant search that triggers their ads goes unchecked, dragging down CTR, wasting impressions, and increasing suspension risk.

This guide covers what negative keywords are, how to find the ones you need, and provides a starter list you can add to your account today.

Key Takeaways - Negative keywords prevent your ads from showing for irrelevant searches - They directly protect CTR (by removing wasted impressions) and budget (by blocking useless clicks) - Mine your Search Terms report weekly for new negatives - Use shared negative keyword lists to apply negatives across all campaigns efficiently - Most Grant accounts need 100-300+ negative keywords

What Negative Keywords Do

When you add a negative keyword, you tell Google: "Never show my ad when someone searches for this term."

Without negative keywords: Your keyword "animal rescue" triggers ads for "animal rescue TV show," "animal rescue video game," "animal rescue officer salary," and "animal rescue near me." The first three are irrelevant; they generate impressions but no clicks (tanking your CTR) or they generate clicks from people who will never engage with your nonprofit (wasting budget).

With negative keywords: You add "TV show," "video game," "salary," and "officer" as negatives. Now your ad only appears for searches genuinely related to animal rescue services. Your CTR goes up, your conversions improve, and your budget goes to people who actually want what you offer.

How to Find Negative Keywords

Method 1: The Search Terms Report (Primary Source)

Your Search Terms report shows every actual query that triggered your ads. It's the single best source of negative keyword ideas.

1. Go to Keywords, then Search terms
2. Set the date range to the last 7-14 days (review this weekly)
3. Sort by Impressions (highest first) to find the biggest volume irrelevant terms
4. Scan for search terms that are clearly not related to your mission
5. Check the box next to irrelevant terms and click "Add as negative keyword"
6. Choose whether to add at the campaign level (blocks the term in that campaign only) or account level (blocks it everywhere)

What to look for:

• Job and career searches: "nonprofit jobs," "[your cause] salary," "careers in animal welfare"
• Entertainment: "documentary," "movie," "TV show," "game," "book"
• Academic: "research paper," "thesis," "case study," "PDF"
• DIY/how-to that isn't your mission: "how to start a nonprofit," "nonprofit business plan"
• Commercial products: "buy," "price," "cheap," "for sale"
• Other organizations: Competitor names, unrelated charities
• Irrelevant locations: Cities or countries where you don't operate

Method 2: Brainstorm Common Irrelevant Categories

Before your account even starts running, you can preemptively add negatives for categories you know are irrelevant:

Jobs and careers: "jobs," "careers," "salary," "hiring," "employment," "vacancy," "internship," "resume," "interview"

Education/academic: "definition," "wiki," "wikipedia," "essay," "thesis," "PDF," "research paper," "case study," "textbook"

Entertainment: "movie," "film," "TV," "show," "game," "song," "lyrics," "book," "novel"

Social media/platforms: "reddit," "quora," "youtube," "tiktok," "facebook," "instagram"

Commercial: "buy," "price," "cost," "cheap," "for sale," "discount," "coupon," "promo code"

Government: "government grant," "federal," "state grant" (unless you're a government-adjacent service)

Method 3: Use Google's "People Also Ask" and Related Searches

Search for your core keywords on Google and look at the "People Also Ask" section and "Related searches" at the bottom. Note any tangents that could trigger your ads irrelevantly.

Negative Keyword Match Types

Negative keywords also have match types, but they work differently from regular keyword match types:

Negative broad match (default): Blocks your ad if the search contains ALL the words in your negative, in any order. Negative free download blocks "free PDF download" and "download free resources" but does NOT block "free" alone or "download" alone.

Negative phrase match: Blocks if the search contains your negative words in the exact order. Negative "job openings" blocks "nonprofit job openings" but does NOT block "openings for jobs."

Negative exact match: Blocks only if the search matches your negative exactly. Negative [nonprofit jobs] blocks "nonprofit jobs" but does NOT block "nonprofit jobs near me."

Recommendation: Use negative broad match for most negatives. It provides the widest protection. Use negative phrase or exact match only when a broad negative would accidentally block searches you want.

Example of when broad is too aggressive: Adding "free" as a negative broad match would block "free food bank near me" and "free counseling services," which might be exactly what you want people to find. Instead, use negative phrase match for specific irrelevant phrases like "free download" or "free game".

Account-Level vs Campaign-Level Negatives

Account-level (shared negative keyword lists): Apply across all campaigns. Use for universal negatives like "jobs," "salary," "wiki." Create these via Tools, then Shared library, then Negative keyword lists.

Campaign-level: Apply to a specific campaign only. Use when a term is irrelevant for one campaign but relevant for another. Example: "volunteer" might be a negative for your Donations campaign (you don't want volunteer-seekers clicking donation ads) but is obviously relevant for your Volunteer Recruitment campaign.

Ad group-level: Apply to a specific ad group. Use for traffic sculpting: ensuring searches go to the right ad group within a campaign.

Recommended structure:

1. Create one shared list of 50-100+ universal negatives applied to all campaigns
2. Add campaign-specific negatives as needed based on each campaign's Search Terms data
3. Use ad-group-level negatives for fine-tuning traffic distribution

Customize this list based on your organization. Remove any terms that might actually be relevant to your mission. A job training nonprofit, for example, should NOT add "jobs" or "employment" as negatives.

How Many Negative Keywords Do You Need?

The exact number depends on your cause area and how many irrelevant searches your keywords attract. Broad cause areas (health, education, environment) tend to need more negatives than narrow niches.

Weekly Negative Keyword Maintenance

Make this a 10-minute weekly habit:

1. Open Search Terms report (last 7 days)
2. Scan for irrelevant terms with high impressions
3. Add them as negative keywords
4. Check if any negatives are accidentally blocking relevant searches (Keywords tab, then "Negative keywords," review for anything that looks too aggressive)
5. Note any new patterns that suggest a new shared list entry

This single habit, done consistently, has a bigger impact on Grant performance than almost any other optimization activity.

Frequently Asked Questions

Can negative keywords hurt my account? Only if they're too aggressive. A negative for "free" would block "free food bank near me," which is probably a search you want. Use specific multi-word negatives rather than single-word negatives for common terms. When in doubt, use negative phrase match instead of negative broad match.

How often should I review negative keywords? Weekly for the Search Terms report. Monthly for a broader review of your negative keyword lists to ensure nothing is accidentally blocking relevant traffic.

Should I use the same negative keywords across all campaigns? Use a shared list for universal negatives (jobs, wiki, movie, etc.). But some negatives should be campaign-specific. "Volunteer" should be a negative in your Donations campaign but obviously not in your Volunteer campaign.

My account has zero negative keywords and CTR is fine. Do I still need them? Yes. Even if CTR is currently above 5%, negative keywords prevent it from dropping. They also improve budget efficiency by directing spend toward people who are more likely to convert. Prevention is easier than recovery.

Do negative keywords work the same globally? Yes. The mechanics are identical. The specific irrelevant terms vary by language and region, but the approach (mine Search Terms, add negatives, maintain weekly) is universal.
