Checklist: 10 Steps to Implement Account-Level Placement Exclusions Without Breaking Campaigns

Stop losing conversions when you block placements: a 10-step checklist for account-level placement exclusions (2026)

If you manage multiple Google Ads campaigns, you know the squeeze: you want stronger brand safety and fewer irrelevant placements, but one wrong exclusion can dry up low-funnel traffic and blow your CPA. In 2026, Google added account-level placement exclusions — a powerful central control — but power without guardrails leads to broken campaigns. This guide gives a practical, step-by-step checklist to implement account-level placement exclusions safely, plus rollback tactics, testing cadence, and common pitfalls to avoid.

Why this matters now (short version)

In January 2026 Google announced account-level placement exclusions across Performance Max, Demand Gen, YouTube, and Display campaigns. This centralizes controls and fixes a long-standing operational headache. But at scale, account-level changes affect automated bidding and learning phases across multiple campaigns simultaneously — so a careful rollout is essential.

"Account-level exclusions stop bad placements at scale. The risk: over-excluding and breaking learning or starving campaigns of conversions."

Use this checklist to balance brand safety and performance. Follow the steps in order; each step includes exact actions, monitoring windows, KPIs and rollback rules.

Quick checklist (TL;DR)

1. Audit current placement performance and set a baseline.
2. Define exclusion taxonomy and risk tiers (Immediate, Monitor, Optional).
3. Create account-level exclusion lists by tier.
4. Run a controlled experiment on a non-critical campaign.
5. Monitor early-learning KPIs daily for 7–14 days.
6. Use incremental rollout (10% → 25% → 100%).
7. Set explicit rollback triggers and automation alerts.
8. Maintain an exceptions list for high-value placements.
9. Document changes, decisions and outcomes for 90 days.
10. Establish ongoing cadence and quarterly reviews.

Step-by-step: 10 steps with actions, KPIs and rollback tactics

1. Audit current placement performance and set a baseline

Before making any account-level changes, capture a performance snapshot across channels and inventory types. This is your safety net to measure impact.

• Export last 30–90 days of placement-level data for Display, YouTube, and in-app (Performance Max and Demand Gen consolidate placement reporting differently — pull asset reports where possible).
• Key fields: placement URL/app, impressions, clicks, conversions, conversion value, CPA/ROAS, view-through conversions, engagement metrics.
• Compute baseline KPIs: conversion rate (CVR), cost per conversion (CPA), cost per click (CPC), share of conversions by placement tier.

Action: Save baseline to a dated sheet and tag any placements currently excluded at campaign or ad-group level.

2. Define an exclusion taxonomy and risk tiers

You need consistent criteria to avoid ad-hoc blocking. Use a three-tier system:

• Immediate: Brand safety violations, piracy, illegal content, fraud — block at account-level immediately.
• Monitor: Low conversion or high bounce placements with large spend — add to account-level but use limited rollout.
• Optional: Low-volume or niche placements — consider campaign-level control instead.

Document the criteria (e.g., >x% viewability below threshold, conversion rate <50% of account baseline, suspicious spikes in CTR with zero conversions).

3. Create account-level exclusion lists by tier

Build separate exclusion lists in Google Ads so you can apply different scopes and rollout schedules.

• List A: Immediate — apply to all campaigns instantly.
• List B: Monitor — apply progressively and monitor learning impact.
• List C: Optional — keep for campaign-level or manual use.

Tip: Name lists clearly with dates and owner. Use a consistent format like "Excl_Immediate_2026-01-XX".

4. Run a controlled experiment on a non-critical campaign

Never push account-wide exclusions live without testing. Choose a campaign that mirrors account goals but is not the primary conversion driver.

• Create a duplicate of the campaign where possible. Apply the account-level list to the duplicate only.
• If duplication isn't feasible, apply List B to a single, mid-budget campaign with automation disabled where possible.
• Run the test for at least one full learning cycle (7–14 days for automated campaigns; up to 28 days for seasonal/low-volume accounts).

KPIs to watch: CPA change (%), conversion volume change (%), impression volume change (%), conversion rate change (%), and ROAS.

5. Monitor early-learning KPIs daily for 7–14 days

Automated campaigns are sensitive during learning. Watch the early indicators closely.

• Daily for days 1–7: impressions, clicks, conversions, CPA. If any KPI moves beyond your tolerance window, pause changes.
• Days 8–14: assess stabilization. Expect temporary fluctuations as machine learning re-optimizes.
• Use control charts or a simple % change rule (example rollback triggers below).

6. Use incremental rollout: 10% → 25% → 100%

Rather than flipping a global switch, roll changes out in stages.

• Start by applying List B to 10% of campaigns by spend or to low-priority geos.
• After 7–14 days without negative impact, expand to 25% and reassess.
• Complete rollout to remaining campaigns only after two stable cycles.

Why this helps: Staged changes reduce the risk that an account-level exclusion interferes with global automated learning.

7. Set explicit rollback triggers and automation alerts

Predefine the trigger thresholds that will automatically signal a rollback. Automate alerts to your team.

• Recommended rollback thresholds (adjust by account):
• Conversion volume drops > 20% vs baseline over a 7-day period.
• CPA increases > 15% vs baseline over a 7-day period.
• ROAS decreases > 15% and not improving after 14 days.
• Impressions fall > 30% and conversion volume also falls.
• Integrate alerts: Google Ads scripts, API-based watch, or third-party monitoring (e.g., Data Studio with automated email alerts).
• Define who has rollback authority and the documented rollback process (who clicks what, expected timeline).

8. Maintain an exceptions list for high-value placements

Some placements may look underperforming but deliver strategic value (brand lift, high-value audience). Keep an exceptions registry.

• Tag placements as "high-value" if they drive assisted conversions or top-funnel lift.
• Use attribution windows and data from brand lift or experiments to validate decisions.
• If a placement shows volatile short-term metrics but long-term value, exclude it only at campaign-level with notes.

9. Document changes, decisions, and outcomes for 90 days

Account-level changes can break months of learning if undocumented. Keep a living change log.

• Record: date, list name, placements blocked, owner, reason, tests run, KPIs before and after, rollback actions.
• Store in a shared folder and link to experiments, creative changes, and promo calendar to avoid attribution errors.

Pro tip: Use UTM tags and consistent naming on campaigns to make post-change analysis easier.

10. Establish ongoing cadence and quarterly reviews

Account-level exclusions are not "set and forget." Market inventory shifts rapidly — especially in 2026 with more CTV, in-app, and short-form YouTube formats.

• Daily checks for 14 days after any substantive change.
• Weekly review for next 6 weeks.
• Monthly health-checks for the next quarter.
• Quarterly strategy reviews to reclassify placements as new inventory and measurement evolves.

Common pitfalls and how to avoid them

Over-exclusion: losing low-cost, high-volume traffic

Blocking too broadly can cut cheap clicks and conversion volume. Avoid removing entire domains without placement-level evidence. Prefer targeted exclusions (subdomains/apps) and staged rollout.

Breaking learning windows for automated campaigns

Machine learning needs stable inputs. Large, sudden exclusions can reset learning and increase CPA. Use duplicates or staged rollout to minimize disruption.

Misattributing seasonal shifts to exclusions

Make sure changes aren't timed near sales, holidays, or creative updates. Always cross-check promo calendar before concluding an exclusion caused performance drops.

Neglecting brand lift and assisted conversions

Short-term CVR drops don't capture assisted value. Use attribution windows and lift studies to evaluate brand-impact placements before excluding.

Rollback tactics: how to recover fast without losing stability

If you hit a rollback trigger, follow a standardized recovery path:

1. Pause the most recent account-level list application (not the whole account).
2. Reinstate prior campaign-level exclusions if they were in place.
3. Return to the prior learning state by restoring placements for 48–72 hours while keeping other variables constant (no creative or budget changes).
4. Monitor KPIs for 48–72 hours. If stable, reintroduce exclusions gradually using a smaller list or staged approach.
5. Document the incident, root cause, and update the taxonomy to prevent repetition.

Emergency rollback checklist (copy/paste):

• Step 1: Unapply List B (Monitor) at account level.
• Step 2: Re-enable campaign-level exclusions that were active before the test.
• Step 3: Notify stakeholders and pause new creative changes for 72 hours.
• Step 4: Re-assess after 72 hours; if KPIs recovered, plan a more conservative rollout.

Testing cadence — what to measure and when

Set a testing cadence that matches your traffic volume and seasonality.

• High-volume accounts (100+ conversions/week): Daily checks first 7 days, then weekly.
• Mid-volume (20–100 conv/week): Daily checks first 10 days, then weekly for 6 weeks.
• Low-volume (<20 conv/week): Extend test windows to 28–45 days to collect statistically meaningful data.

Primary KPIs: conversions, CPA, ROAS, impression share by placement, CVR. Secondary: view rate (YouTube), watch time, and assisted conversions.

2026 trends that affect placement exclusions

Implementations in 2026 must account for a few technical and market shifts:

• Greater automation: Performance Max and Demand Gen are ubiquitous; account-level controls now influence cross-channel learning.
• Privacy-first measurement: With enhanced privacy rules and deprecation of third-party cookies, placement-level signals are noisier — rely more on first-party conversions and modeled data.
• Ad inventory shifts: CTV, in-app, and short-form YouTube continue to grow. Each has different placement granularity and brand-safety profiles.
• Supply-side consolidation: Programmatic sellers and exchanges are consolidating; a domain block can remove far more inventory than before.

Real-world example (hypothetical case study)

Example: Mid-market SaaS brand, Jan–Mar 2026. Baseline: 350 conv/month, CPA $120, 60% of conversions from Performance Max. They created List A (Immediate) with 12 domains and List B (Monitor) with 45 placements flagged for low CVR.

• Test: Applied List B to a duplicate Performance Max campaign (10% account spend).
• Result after 14 days: impressions down 9%, conversions down 6%, CPA stable (+2%).
• Expansion to 25%: conversions down another 8% and CPA rose 18% → triggered rollback.
• Rollback actions: Unapplied List B, restored campaign-level settings, paused creative tests for 72 hours.
• Learning: Two placements in List B were content-syndication domains that drove high-volume top-funnel conversions and assisted half their final purchases. They reclassified those placements as "exceptional" and removed them from account-level exclusions.

Outcome: After a conservative re-rollout, the account ended the quarter with a 3% decrease in impressions but a 2% improvement in CPA and improved brand-safety controls.

Templates and automation you should use

• Baseline export template (spreadsheet) with built-in KPI calculations and control charts.
• Change log template: date, owner, list name, placements added/removed, rationale, KPIs pre/post.
• Alerting: Google Ads scripts or API checks for your defined rollback thresholds, integrated with Slack or email.
• Automation for staged rollout: use labels and scripts to apply lists to a subset of campaigns programmatically.

Final checklist before you click "Apply"

• Baseline saved and dated.
• Exclusion taxonomy defined and lists created.
• Non-critical test campaign selected and duplicate created.
• Rollback triggers and automation set up.
• Stakeholders informed and documentation template prepared.
• Testing cadence scheduled and monitoring responsibilities assigned.

Parting advice from the field

Account-level placement exclusions are a high-value control for brand safety and operational efficiency in 2026 — but treat them like surgery, not a band-aid. Start small, measure, and always keep a rollback path. When used properly, account-level lists reduce manual work and streamline safety across channels without sacrificing performance.

Immediate action: Export your baseline today, then schedule a 2-week controlled test this week. Don’t flip every switch at once.
