Account-Level Placement Exclusions: What Marketers Should Do With Their Landing-Page Redirects

Hook: Your account-level placement exclusions aren't enough — here's how to keep excluded placements from landing ad traffic on your live pages

Marketers and site owners already feel the pain: you set placement exclusions in Google Ads, but suspicious or low-quality inventory still finds its way to your campaigns — and worse, to your live landing pages. In 2026 Google added account-level placement exclusions to simplify blocking at scale, but exclusions are one control among many. To truly keep ad traffic away from excluded placements and risky inventory, you need intentional landing-page routing and robust edge-level redirect rules at the edge.

The problem today (2026 context)

Google announced account-level placement exclusions on January 15, 2026, allowing a single exclusion list to apply across Performance Max, Demand Gen, YouTube, and Display campaigns. That change solved fragmented controls — but new ad formats and increasing automation mean that blockers alone don’t guarantee the right traffic lands where you want.

"Account-level placement exclusions let advertisers block unwanted inventory across all campaigns from a single setting." — Google Ads announcement, Jan 2026

Why exclusions alone fall short:

• Ad networks and programmatic partners can surface inventory that routes differently (in-app wrappers, native SDKs, or third-party redirects), so an exclusion in Google Ads doesn’t always stop a view / click event from being reported.
• Tracking parameters and ValueTrack parameters may not be available for every placement; some clicks arrive with limited attribution data.
• Automation and campaign types like Performance Max mean creative and targeting shift dynamically; you need real-time routing safeguards.

What you should protect: landing experience vs ad inventory

Two separate but related goals:

• Protect the landing experience: ensure excluded or suspicious ad placements never land users on conversion pages that harm brand safety, inflate costs, or trigger policy problems.
• Protect ad inventory & measurement: preserve accurate attribution and maintain campaign performance by isolating traffic that comes from low-quality placements so it doesn’t distort your CPA/CRO signals.

High-level strategy: layered controls

Combine three layers to get reliable results:

1. Prevent: Use Google Ads account-level exclusions and third-party verification (IAS, DoubleVerify) to stop known bad inventory.
2. Detect: Capture placement-specific data at click time via URL parameters, referer patterns, and ad tokens. Monitor behavior (session duration, engagement, conversion rate) for anomalies.
3. Route: Apply edge-level redirect rules to route excluded or suspicious traffic to safe landing experiences (neutral pages, suppression pages, or lighter funnels) without breaking attribution.

Practical workflow — a step-by-step guide

1) Audit your placements and build a single source of truth

Start by exporting placement-level performance from Google Ads, DSPs, and verification partners. Create a canonical list of domains and app IDs you want excluded. Because account-level exclusions are now available, make that list the primary source for Google Ads — but maintain it in your link-management platform for runtime routing and monitoring.

1. Export placement reports (last 90 days) from Google Ads, Performance Max insights, and YouTube placements.
2. Flag placements with high CTR / low conversion, short session times, or suspicious referral patterns.
3. Merge with vendor blocklists (IAS/DoubleVerify) and internal risk lists.

2) Configure account-level exclusions in Google Ads (fast win)

Apply your canonical list to Google Ads as an account-level placement exclusion list. This enforces a baseline block across campaigns and reduces spend on known bad inventory.

Tip: tag exclusions with categories (fraud, brand_safety, low_quality) so you can audit changes and match routing behavior later.

3) Instrument your ad URLs to capture placement signals

To route reliably at the edge, you must capture placement metadata at click time. Use two mechanisms:

• ValueTrack or custom parameters in ad destination URLs — populate tokens like campaignid, adgroupid, and placement tokens available for your channel. Verify token names in Google Ads help (ValueTrack parameters change over time); fallback to a campaign-specific utm_ param.
• Final URL suffix — append a final URL suffix in Google Ads with a deterministic set of parameters that your redirect system expects (for example, &placement={placement}&gclid={gclid}).

Always test how parameters are populated for each ad format (YouTube vs Display vs In-App).

4) Implement edge redirect rules — keep redirects fast and deterministic

Put routing logic at the CDN/edge (Cloudflare Workers, Fastly, AWS Lambda@Edge, or a link-management platform). Edge-level rules run before your origin loads and preserve performance — critical for ad landing experience and Quality Score.

Core rule order (evaluate top-to-bottom):

1. Parameter match: if URL contains a placement token matching your excluded list, route accordingly.
2. Referer match: if Referer header matches an excluded domain pattern, route accordingly.
3. Behavioral heuristics: if parameters absent, apply heuristics (IP + UA anomalous patterns or new high-CTR low-engagement signals) to quarantine traffic.
4. Fallback: default to main landing page for verified good traffic.

Example: pseudo-JSON rule set (readable, implementable in most link managers):

{
  "rules": [
    {"id":"block_placements","match": {"param.placement": ["badsite.com","lowqual.app"]},"action": {"redirect":"/suppression?source=placement_block","status":302}},
    {"id":"referer_block","match": {"header.referer": ["badsite.com","*.suspiciousnetwork.net"]},"action": {"redirect":"/suppression?source=referer_block","status":302}},
    {"id":"heuristic_quarantine","match": {"session.risk_score": ">70"},"action": {"redirect":"/review?source=heuristic","status":302}},
    {"id":"default","action": {"redirect":"/landing?source=ad","status":200}}
  ]
}

Notes:

• Use 302/307 (temporary) redirects for click routing to preserve campaign measurement and avoid caching as permanent — this keeps your analytics clean and allows you to change routing rules without SEO surprises.
• Keep the suppression page minimal and fast; avoid conversion pixels that could pollute performance metrics. Use it to surface a safety message or an alternative funnel (e.g., book a demo instead of immediate sign-up).

5) Preserve attribution and analytics hygiene

Redirects can break UTM and platform-level parameters if mishandled. Follow these rules:

• Always forward query parameters unless explicitly removing sensitive tokens. If you route to a suppression page, append utm parameters that indicate traffic was quarantined (utm_source=ad&utm_medium=display_quarantine).
• Use server-side event forwarding to send click and conversion signals to analytics and your CDP. That ensures measurement continuity even if the client never reaches the original landing page.
• Normalize identifiers — capture gclid/click_id in server logs at the edge and send to your attribution system.

6) Run a controlled test and monitor key metrics

Before wide deployment, roll out routing rules to a small percentage of traffic (1–5%). Track these KPIs:

• CTR and CPC changes for affected campaigns
• Session duration, bounce rate, and pages/session for quarantined vs baseline traffic
• Conversion rate and CPA for quarantined traffic after changes
• False positives / false negatives on placement detection

How to handle specific scenarios

Scenario A: Excluded placements still click through via in-app wrappers

Problem: Your account-level exclusions are set, but clicks arrive with little placement data because they came through an app webview or SDK wrapper.

Solution:

• Rely on referer, UA, and app-IP patterns at the edge to detect wrappers.
• If parameters are missing, apply conservative routing to a verification page or suppression funnel that requires minimal user action and doesn’t count as a full conversion.
• Flag the placement for your exclusion list if you confirm it violates quality rules.

Scenario B: High-risk YouTube placements

YouTube can route from multiple contexts (desktop, mobile app, partner apps). Account-level exclusions reduce spend but you may still get undesirable views. Recommended approach:

• Use Google Ads placements + channel exclusions at account-level.
• Instrument your click URLs with Video-specific tokens where available and route based on those tokens.
• For ambiguous signals, send traffic to a light pre-landing/interstitial to confirm intent before the main funnel.

Scenario C: Fraud spikes from new traffic sources

If you see sudden CTR spikes with low conversions, use automated rules that raise traffic risk scores and quarantine traffic immediately. Integrate with verification vendors and your DSP to pull those placements into account-level exclusion lists.

Technical tips — edge, headers, and tokens to use

Signals to evaluate at the edge (in priority order):

• URL parameters — utm_campaign, campaignid, placement, gclid, click_id.
• Referer — domain-level and path-level matching.
• User-Agent and device — identify app webviews and automated traffic.
• IP reputation and ASN — cross-reference with known ad fraud IP lists.
• Geolocation — enforce country targeting if your campaigns are geo-restricted.
• Behavioral heuristics — rapid click patterns, cookie rejection, or unrealistic engagement metrics.

When implementing rules, prefer deterministic matches first (explicit placement param), then probabilistic heuristics (risk scoring) second. Deterministic matches reduce false positives.

SEO and policy considerations

Many teams worry that redirects will harm organic search. Follow these guidelines:

• Use temporary redirects (302/307) for ad click routing so search engines don’t treat them as permanent.
• On suppression or verification pages, add a rel="noindex" meta tag if the page exposes non-canonical content to avoid diluting SEO.
• Keep landing paths crawlable for canonical pages; do not use broad server-side blocks that prevent organic crawlers from accessing live content.

Monitoring, feedback loops, and automation

Set up automated pipelines to keep your exclusion lists and routing rules current:

• Daily export of placement performance and anomaly detection (CTR vs conversion deviations).
• Automated enrichment with vendor risk signals; if a placement is flagged by IAS/DoubleVerify, push it to your account-level exclusion and your edge rule list.
• Auto-heal policies: if quarantine traffic shows normal conversion behavior for 7 days, remove from quarantine automatically.

Real-world example (compact case study)

Client: Mid-market SaaS in fintech, 2025–2026

Problem: After shifting budget into Performance Max and YouTube, the client saw a 42% spike in low-quality clicks from native app inventory. Account-level exclusions were added in Jan 2026, but suspicious clicks continued and inflated CPA.

What we did:

1. Built a canonical exclusion list and applied it at the Google Ads account level.
2. Instrumented all ad destination URLs with a final URL suffix capturing placement tokens where possible and a fallback utm_source=ad_inapp.
3. Implemented edge redirect rules in 24 hours that routed flagged placement clicks to a lightweight verification page and captured gclid on the server.
4. Created a daily pipeline to sync vendor signals into the exclusion list.

Results (30 days):

• Illegal or suspicious clicks quarantined: 18% of display traffic
• Net CPA improved by 21% after quarantining and reallocation
• False positives < 0.7% after one-week tuning

Checklist: What to implement this week

1. Export placement reports and build a canonical exclusion list.
2. Apply exclusions at Google Ads account level (Jan 2026 feature) and tag them by reason.
3. Append final URL suffix in Google Ads with placement/click tokens you expect to receive.
4. Deploy edge redirect rules that detect placement tokens, referers, and risky heuristics.
5. Preserve and forward gclid/utm params; log them server-side for attribution.
6. Run a controlled rollout (1–5%) and monitor CTR/CVR/CPA and session quality metrics.

Advanced strategies for 2026 and beyond

As ad platforms push more automation and privacy changes (late 2025–2026), rely less on client-only signals and more on server-side, edge, and verification integration:

• Server-side tagging: move conversion attribution to server endpoints to retain measurement when client signals become sparse.
• Edge A/B routing: serve alternate funnels to suspicious traffic to preserve conversion windows without damaging main funnels.
• ML risk scoring at the edge: apply lightweight models that run at the CDN to classify and quarantine risky clicks in real time.

Common pitfalls and how to avoid them

• Overblocking: Conservatively quarantine traffic first; avoid a blanket redirect that catches high-value prospects. Use a short quarantine TTL (48–72 hours) for retesting.
• Breaking attribution: Never strip gclid/clickid — capture them at the edge and forward to your analytics and ad platforms.
• Slowing the landing page: Keep redirect logic at the edge and minimize additional client-side redirects or heavy JS on the pre-landing pages.

Final takeaways

Account-level placement exclusions in Google Ads (2026) are a critical new control, but they are not a complete solution. To keep excluded placements and suspicious inventory from landing on your conversion pages, you need a layered approach: centralized exclusion lists, deterministic click instrumentation, and edge-level redirect rules that quarantine or reroute risky traffic while preserving attribution. Do this and you’ll protect your brand, improve CPA, and maintain measurement integrity even as ad formats and privacy controls evolve in 2026.
