Exclusions vs Negative Keywords: What's Best for Protecting Launch Spend?

Stop launch spend leakage now: a practical decision guide for 2026

Launching a campaign and watching budget leak to irrelevant sites, low-quality apps, or off‑brand YouTube channels is one of the fastest ways to blow a launch budget and miss KPI windows. Marketers in 2026 face faster timelines, more automated buying (Performance Max, Demand Gen) and higher stakes for launch ROAS. That makes choosing the right inventory controls—account-level placement exclusions vs campaign- or site-level negative keywords—a tactical decision that directly protects launch spend.

The evolution you need to know (late 2025–early 2026)

Google accelerated centralized controls in early 2026. On January 15, 2026 Google Ads added account-level placement exclusions, enabling teams to block websites, apps and YouTube placements across all eligible campaigns from a single setting. This is a meaningful step: it fixes a common operational pain point where exclusions were fragmented across campaigns and ad groups, especially in accounts running Performance Max and Demand Gen where automation chooses placements.

"Advertisers can now apply one exclusion list at the account level. Exclusions apply across Performance Max, Demand Gen, YouTube, and Display campaigns." — Google Ads rollout, Jan 15, 2026

That update shifts the decision from “can we block X?” to “where and how should we block X?” This guide gives a clear, actionable decision path and playbook geared to launch campaigns—so you protect spend without crippling performance.

Quick operational definitions (contextual, not introductory)

Use these working definitions for rapid decisions in launch planning:

• Account-level placement exclusions: Centralized lists that block placements (sites, apps, YouTube channels/placements) across eligible campaigns. Applies broadly to Display, YouTube, Performance Max and Demand Gen in Google Ads.
• Campaign-/ad group-level negative keywords: Query-level or site-level blocks applied to search, shopping, or individual campaigns to prevent certain queries or site placements from triggering ads.
• Inventory control: The combined set of rules, lists and workflows you use to control where ads appear during a launch.

Core tradeoffs at a glance

• Scope: Account-level = broad, one-to-many. Campaign negatives = surgical, one-to-one.
• Speed: Account-level changes propagate instantly across campaigns. Campaign lists require repeated application or shared lists per campaign.
• Risk to reach: Account-level exclusions can reduce scale faster if over-applied. Campaign negatives let you protect a single campaign while preserving reach elsewhere.
• Automation compatibility: Account-level exclusions are essential for automated formats (Performance Max) where campaign-level control is limited.

Decision guide: When to use account-level placement exclusions

Use account-level exclusions when your priority is consistent, cross-campaign inventory control during a launch window. Typical scenarios:

• Launch with broad automated formats (Performance Max, Demand Gen): These formats automatically place ads across channels. Account-level exclusions are the only reliable way to ensure a single unwanted placement is blocked account-wide.
• Brand safety and compliance: If your launch requires strict brand-safe inventory (e.g., regulated categories, sensitive topics), centralizing exclusions ensures no campaign slips through.
• Large accounts and agency-managed portfolios: When multiple teams or clients share an account, centralized lists reduce human error and duplicate work.
• Fast, pre-launch blacklists: For pre-emptive blocking of known low-quality inventory—fraud-prone app categories, invalid traffic hot spots, known copyright-infringing domains—apply account-level blocks for speed.

Practical rule: when a placement category or domain should be blocked for every campaign in the launch period, make it an account-level exclusion.

Decision guide: When to use campaign- or site-level negative keywords

Use campaign- or ad-group-level negatives when you need precision and flexibility. Typical scenarios:

• Search & Shopping launches: Negative keywords prevent irrelevant or low-intent queries from wasting search budgets. Apply them at campaign level to preserve learnings in other campaigns.
• Audience-specific campaigns: If a retargeting or high-intent cohort should exclude certain queries or placements that broad prospecting can include, apply negatives at the campaign level.
• Testing & experiments: Run a campaign-level experiment that excludes or includes specific placements/queries. Keeping the control and test isolated is easier with campaign-level negatives.
• Localized launches: If you launch in multiple markets and only one market needs bespoke exclusions, apply at the campaign level to avoid collateral impact.

Practical rule: when the exclusion is relevant to the strategy or audience of a specific campaign (not the entire account), keep it campaign-level.

Use cases and step-by-step examples

1) Nationwide consumer launch using Performance Max

Situation: You’re launching a nationwide DTC product with Performance Max as the primary prospecting vehicle, plus Search for high-intent queries.

1. Create an account-level placement exclusion list for broad categories: gambling/adult/low-quality app categories and known brand-safety concerns.
2. Apply campaign-level negative keywords in Search for queries tied to unrelated product categories or support phrases (e.g., "free", "manual", "repair") that drive clicks but not conversions.
3. Monitor performance in first 72 hours. If Performance Max shows spend on a placement type not covered by your account list, add it account-wide.

2) B2B product launch with targeted search and LinkedIn retargeting

Situation: B2B launch where reach matters less than lead quality.

1. Keep account-level exclusions minimal to avoid cutting reach for niche audiences. Block only obvious fraud/vulnerability sources at account level.
2. Use campaign-level negative keyword lists aggressively in prospecting search campaigns to prevent low-intent or consumer-focused queries.
3. Use placement exclusions only if you observe low-quality placements eating budget in display retargeting; prefer site-level negative lists bound to the retargeting campaign.

3) YouTube-heavy brand launch with influencer placements

Situation: You plan both organic influencer spots and paid YouTube buys; brand safety is paramount.

1. Build an account-level placement exclusion list that blocks categories and specific channels you’ll never align with (controversial creators, piracy channels).
2. Create a campaign-level include list (whitelist) for targeted influencer partner channels when running paid YouTube alongside organic placements. Use negatives at campaign level to exclude all but the whitelist if necessary.

Practical playbook: Pre-launch to launch week (copyable checklist)

Pre-launch (T-14 to T-3)

• Audit last 12 months of placement and query reports. Export top spend placements and top wasted queries per campaign.
• Create two canonical lists: Account - Core Exclusions and Campaign - Tactical Negatives. Use descriptive naming: "ACC_Excl_CoreBrandSafety_2026Q1" and "CMP_Search_Neg_B2B_010126".
• Map sensitive content categories, regulatory restrictions and brand partner exclusions into the account-level list.
• Define KPIs and thresholds for corrective actions (e.g., stop if CPA > 2x target for 24 hours on a particular placement, or CTR < 0.1% with spend > $200).

Launch week (T-2 to T+7)

• Apply account-level exclusions before turning automation live. Document the applied list with a rollout memo and owner.
• Apply campaign negatives for search/shopping where query intent matters. Use shared negative lists where possible to standardize.
• Set automated alerts (email/slack) for unusual placement spend or CPA spikes. Use hourly checks for the first 72 hrs then move to daily.
• Hold a daily 15-minute launch stand-up with marketing, paid search, and analytics to review placement exceptions and add/remove blocks.

Post-launch (T+7 to T+30)

• Run a placement performance deep dive at day 7 and day 30. Convert transient campaign-level negatives into account-level exclusions only if the placement is demonstrably bad across campaigns.
• Version control your exclusion lists. Keep changelogs so you can roll back if you over-excluded and damaged ML learning.
• Update documentation and templates for the next launch—capture what cost you avoided and what reach you sacrificed.

Measurement: How to prove exclusions protected spend

Account for the effect of exclusions with these methods:

• Pre/post placement spend analysis: Compare spend and CPA on placements that were excluded vs the account baseline. Tag the date/time exclusion was applied and measure delta in wasted clicks.
• Control groups: For large budgets, run a hold-out where a small percentage of traffic excludes the account-level list. Compare conversion rate and cost per conversion across the groups.
• Attribution alignment: Use server-side events and CRM reconciliation to check whether excluded placements produced low-quality leads (no-op in CRM or high churn).
• Lift tests: For brand metrics, run YouTube Brand Lift tests on included vs excluded content sets to measure view-through and ad recall differences.

Key metrics to watch during launch: CPA/Lead, Conversion Rate, CTR, View-through rates, ROAS, and % spend on top 20 placements.

Best practices and pitfalls

• Don’t over-exclude early. Overly broad account exclusions in the first 48–72 hours can starve automated formats of learning data and raise CPAs. Start with conservative account-level blocks focused on brand safety and fraud, then iterate.
• Use shared negative lists. For repeatable launches, maintain shared campaign negative lists in your manager account to speed rollouts and ensure consistency.
• Document every change. Name lists with dates and owners. When you remove a placement from an exclusion list, log why and what test or data prompted that change.
• Balance brand safety vs scale. Some placements look low quality but convert at scale for niche products—test before permanently excluding.
• Coordinate with creative strategy. If you block YouTube placements, make sure influencer or paid partners are accounted for in a whitelist to avoid conflicting buys.

Templates: Naming conventions and list examples

Use consistent naming to avoid confusion. Examples:

• ACC_Excl_BrandSafety_20260115
• ACC_Excl_FraudApps_20260115
• CMP_Search_Neg_B2B_Q1_202601
• CMP_Display_Neg_Retargeting_LAUNCH1

Example negative keyword categories for campaign lists (adapt per product):

• Support terms — "manual", "customer service", "repair"
• Free/trial intent — "free", "crack", "serial"
• Irrelevant product terms — terms for other product categories you don’t serve

Automation and future-proofing (2026 outlook)

Through 2026 we expect platforms to continue shifting controls upward: centralized account-level guardrails, more API-driven list management and better reporting for automated placements. That means two practical investments that will pay off:

• Centralized exclusion governance: Treat inventory controls as a governed asset—versioned lists, owners, and SLAs for changes.
• Instrumentation & BI: Integrate placement and query data into your launch dashboards (looker, Data Studio, or internal BI). Automate alerts for anomalies.

Expect integrations with CM360 and third-party verification (IAS, DoubleVerify) to be tighter in 2026 — use them to cross-check whether excluded placements correlate to IVT or poor viewability.

Final decision framework — a concise checklist

1. Is the launch using automated, cross-channel formats? If yes, prioritize account-level exclusions for brand-safety and fraud blocks.
2. Is the exclusion relevant across all campaigns and geographies? If yes, use account-level; if no, use campaign-level.
3. Do you need to run an isolated test or experiment? Keep negatives at campaign level for isolation.
4. Will the exclusion meaningfully reduce scale or impair ML learning? If yes, delay permanent account-level exclusion until you have conversion data.
5. Have you instrumented alerts and a rollback plan? If no, put those in place before applying broad account-level exclusions.

Closing: two practical takeaways

Takeaway 1: Use account-level placement exclusions for consistent brand safety and to control automated format behavior across campaigns—but start conservatively and iterate.

Takeaway 2: Use campaign- and ad-group-level negative keywords when you need surgical control, experiments, or market-specific logic that shouldn’t impact account-wide learning and reach.
