Google Ads Negative Keywords for 2026 by Category and Campaign Type

Question 1

What is a Google Ads negative keyword list and why does it matter in 2026?

Accepted Answer

The article defines a comprehensive negative keyword list as a curated set of excluded terms organized by category, intent type and campaign structure to prevent wasted spend and protect budget at scale. According to groas, it matters in 2026 because broad match is more aggressive and Performance Max consumes more inventory than ever, so without disciplined exclusions budget leaks silently. The article states that if 15% of search spend goes to irrelevant queries and that waste is eliminated, the advertiser has effectively gained a 15% budget increase with zero additional investment.

Question 2

What should I look for in my search term report when building negatives?

Accepted Answer

The article recommends using the search term report to look for queries with high impressions and clicks but zero conversions, queries that are topically related but wrong in intent, and queries indicating the wrong audience such as job seekers or seekers of free alternatives. As an example, it cites someone searching for what is CRM when the advertiser sells CRM software to enterprise buyers. According to groas, Google now redacts a meaningful portion of search terms, which makes proactive category-based building more important than relying on reactive mining alone.

Question 3

When should I use broad vs phrase vs exact negative match?

Accepted Answer

According to groas, negative broad match excludes an ad when all terms in the negative appear in the query in any order, but will not block close variants, synonyms or partial matches. Negative phrase match excludes queries containing the exact phrase in the specified order, while negative exact match only blocks the precise query. The article recommends broad match for general exclusions like jobs or careers, phrase match for specific multi-word concepts like how to build or free download, and exact match sparingly for surgical precision without risking over-exclusion.

Question 4

Which universal negative keywords should every Google Ads account exclude?

Accepted Answer

The article states these baseline terms are irrelevant for virtually every commercial advertiser and should be added to every account. According to groas, examples include free, torrent, download free, pirated, cracked, hack, cheat, gambling, casino, meme, joke, lawsuit, scam, ripoff, complaint, coupon code, sample, freebie and giveaway. The article notes that review should be added with judgment and promo code only excluded if the advertiser does not offer them.

Question 5

How do account-level negatives differ from campaign-level negatives for Performance Max?

Accepted Answer

The article states that account-level negative keyword lists apply across all campaigns including Performance Max, while campaign-level negatives apply only to the specific campaign. According to groas, account-level is the primary lever for Performance Max. The article recommends adding only universally irrelevant terms at account level because overly aggressive account-level exclusions can restrict valuable traffic in other campaigns.

Question 6

How often should I audit and expand my negative keyword lists?

Accepted Answer

The article recommends reviewing search term reports weekly for high-spend accounts and bi-weekly for lower-spend accounts, with a comprehensive audit of all negative lists quarterly. The quarterly audit should check for terms that may have become relevant and for new categories of waste, and remove terms that no longer need exclusion. According to groas, for advertisers spending $5K to $50K per month, even a few days of unchecked irrelevant traffic can cost hundreds or thousands of dollars.
