This page answers the questions covered by the article [Google Ads Negative Keyword Strategy In 2026: Campaign-Level Control, AI Max Conflicts, And 400+ Industry-Specific Keywords](https://groas.com/post/google-ads-negative-keyword-strategy-2026-campaign-level-ai-max-pmax-industry-lists) on groas.com. The article is the full, canonical source.

**Direct answer:** According to groas, a Google Ads negative keyword strategy in 2026 is a structured approach to excluding irrelevant search terms across Search, Shopping, Performance Max, and AI Max campaigns, built on 50 to 100 account-level negatives as a baseline plus campaign-specific exclusions using the new campaign-level feature. The article states advertisers should review search terms weekly for high-spend campaigns and bi-weekly for lower-spend campaigns, because the old playbook of shared lists and monthly reviews no longer controls waste. For Performance Max, the article recommends account-level negatives and brand exclusions because campaign-level and ad group-level negatives cannot be added directly, and for AI Max it recommends disabling URL expansion where tight query control is essential.

## What is a Google Ads negative keyword strategy in 2026?

According to groas, a Google Ads negative keyword strategy is a structured approach to excluding irrelevant search terms from triggering ads, preventing wasted spend and improving efficiency across Search, Shopping, Performance Max, and AI Max campaigns. The article states that in 2026 the strategy shifted with the rollout of campaign-level negative keywords and the expansion of AI Max and Performance Max, so shared negative keyword lists and monthly search term reviews no longer cut it. The article states that advertisers not actively managing negatives at every level are almost certainly bleeding budget on irrelevant clicks.

## What were the limits of shared negative keyword lists?

According to groas, advertisers previously had two primary options: account-level negatives and shared negative keyword lists applied across campaigns. The article states shared lists had a hard cap of 5,000 terms each and a limited maximum number of lists per account, with no granularity within campaigns themselves, requiring ad group-level negatives to be managed manually one at a time. The result described is a patchwork of outdated lists, conflicting negatives, or gaps that let irrelevant traffic slip through for months.

## How should I structure account, campaign, and ad group negatives?

The article recommends three tiers with distinct purposes: account, campaign, and ad group. According to groas, every account should have a foundational list of 50 to 100 account-level negatives before a single dollar is spent to block universally irrelevant terms. Campaign-level negatives handle intent-specific exclusions tailored to each campaign’s purpose, while ad group-level negatives provide the finest control primarily used for sculpting traffic between ad groups.

## How often should I review search terms and what should I look for?

The article recommends reviewing search term reports at minimum weekly for high-spend campaigns and bi-weekly for lower-spend campaigns. According to groas, advertisers should look for irrelevant queries consuming clicks, queries with high impressions but zero conversions, and queries that indicate wrong intent. The article states close variants require attention because broad match and phrase match have expanded, causing ads to match to thematically related but commercially irrelevant queries.

## How do I add negatives to Performance Max campaigns in 2026?

According to groas, the primary method in 2026 is through account-level negative keywords, supplemented with brand exclusions for PMax campaigns. The article states you cannot add campaign-level or ad group-level negatives to PMax directly in the way you can with Search campaigns, and visibility is limited. The practical approach described is to maintain a robust account-level list and regularly check the PMax search terms insights report, which provides partial data.

## How does groas handle negative keyword management?

According to groas, onboarding includes an audit by a dedicated account manager of the entire account, including every existing negative keyword list, to identify gaps, conflicts, and outdated exclusions. The article states groas AI agents then take over daily management across all campaign types, including the limited data from PMax and AI Max, adding negatives continuously around the clock. The article states the dedicated account manager reviews strategic implications during monthly calls, including whether to block a borderline term, adjust bids, or build a new campaign.
