Best Google Ads fraud protection in 2026: an honest tool-by-tool ranking
The Feb 2026 Fraud Blocker benchmark, drawn from 104 million clicks across 43,701 accounts over six months, put the average Google Ads invalid click rate at 11.4%. Performance Max came in at 12.1%. Smart at 28.6%. Display and Video at 35.5%. Juniper projects $100B+ in global ad fraud losses for 2026 rising to $172B by 2028. Google's own GIVT filter catches roughly 5 to 15% of total invalid traffic; independent studies show 15 to 35% real IVT. The gap is where third-party tools earn their fee.
The complication is that the format Google is pushing all the spend into, Performance Max, is structurally off-limits to those tools. Google blocks third-party API access to PMax management. So the click-side IP-blocking model that ClickCease, ClickGuard, and Fraud Blocker built in 2014-2018 cannot reach the surface where most 2026 fraud actually happens.
This page ranks fraud protection tools honestly. By Google Ads-native depth, by PMax coverage (none have full coverage, all bury this in FAQs), by Smart Bidding signal protection, by conversion-side filtering through Enhanced Conversions and server-side CAPI. Pricing is named, lock-ins are flagged, and the conversion-side wedge most click-side tools refuse to address gets its own tier.
Quick stuff people keep asking
What is the best Google Ads fraud protection? Depends on stage. Sub-$5K/mo Google Ads spend, Click Guardian or ClickPatrol. $5K-$50K/mo, ClickGuard or Fraud Blocker. $50K+/mo, Lunio for cross-channel breadth or DataCops for conversion-side filtering. Enterprise with bots threatening checkout, HUMAN Security or DataDome.
Does Google refund click fraud automatically? Partially. Google credits GIVT automatically and approves around 20-25% of manual SIVT refund claims (per Lunio analysis). The 60-day window is short. Most legitimate fraud waste is never recovered.
Does ClickCease work with Performance Max? No. Google does not allow third-party software to monitor or manage Performance Max or Smart campaigns. ClickPatrol, Polygraph, and ClickCease itself confirm this in their docs. Click-side tools fundamentally cannot reach PMax inventory.
How do I block bot clicks on Google Ads? Two layers. Click-side: IP and placement exclusion via tools like ClickGuard, Fraud Blocker, Lunio. Conversion-side: filter fraudulent conversions before they reach Smart Bidding via Enhanced Conversions or server-side CAPI. The second layer is what survives PMax's API lock-out.
What percentage of Google Ads clicks are fraudulent? Average 11.4% across 104M clicks (Fraud Blocker, Feb 2026). PMax 12.1%. Smart 28.6%. Display and Video 35.5%. App 3.3%. Verticals like Finance, Home Services, Legal, and Real Estate report up to 42% IVT.
Tier 1: SMB click-side fraud blockers (the ClickCease cohort)
Fair pricing, easy setup, IP blocking automated to Google's negative-IP list. The category that built the SMB fraud-protection market and that PMax is now rendering partially obsolete.
1. ClickCease (CHEQ Essentials)
The Good: most popular SMB tool by raw count, claimed 14,000+ customers and 2,000 behavioral tests per visit. 7-day free trial. Direct integrations with Google, Meta, and Microsoft Ads. Backed by CHEQ enterprise tech post-acquisition.
Frustrations: top Trustpilot complaint is a subscription-trap pattern, monthly price is prominent and the 12-month annual lock-in is hidden in smaller text. Cancellation does not stop billing through the term. Month-to-month is 30%+ higher than the displayed monthly-billed-annually price ($84/$104/$124 vs $63/$78/$93). Cannot manage PMax (Google API restriction).
Wish List: real cancel-anytime billing. Clearer disclosure of the annual lock-in.
Value for Money: 6/10. Solid detection, big customer base, but read the contract before signing.
Pricing: 3 tiers, $63/$78/$93 monthly billed annually, $84/$104/$124 month-to-month, 12-month commitment.
2. ClickGuard (rebranded Oct 2025)
The Good: October 2025 rebrand shipped a redesigned dashboard plus AI cross-channel reporting (Google, Meta, Microsoft Ads). Granular click-rule engine for power users. Multi-currency billing (USD, EUR, GBP). Cancel anytime, no long-term contract.
Frustrations: entry pricing jumped post-rebrand. Lite is now $74/mo (was $59), Standard $119, Pro $159. Lite caps at $5K/mo ad spend, forcing most legit advertisers into Standard. Setup more complex than ClickCease.
Wish List: self-serve free tier. Native TikTok and LinkedIn Ads blocking.
Value for Money: 7/10. More sophisticated than ClickCease for power users, expect to land on the $119-$159 tier.
Pricing: Lite $74/mo (1 site, $5K spend), Standard $119/mo (3 sites, $50K spend), Pro $159/mo (unlimited sites, $100K spend).
3. Fraud Blocker
The Good: cheapest credible entry tier at $69/mo, priced ~15% below comparable competitors. Proprietary scoring on 100+ signals per visitor. Strong review base (G2 4.6, Capterra 4.7, Trustpilot 4.4). Publishes the most-cited industry IVT benchmark (11.4% across 104M clicks, Feb 2026).
Frustrations: AppSumo reviewer flagged it as reactive, only adds negative IPs after the fact, and Google's negative-IP list expires every 30 days. Same annual-billing-disguised-as-monthly trap as competitors. Reports occasionally show wrong fraud metrics.
Wish List: real-time pre-click blocking. Honest monthly billing toggle.
Value for Money: 6.5/10. Cheapest legitimate option. Good for SMB negative-IP automation, not for shops expecting magic.
Pricing: from $59/mo annual / $69/mo monthly, 14-day free trial.
4. ClickPatrol
The Good: 800+ data points per click, 99.97% bot-detection accuracy claimed. Four protection modules (AdProtector, AudienceProtector, DataProtector, FormProtector). Strong review base (G2 4.6, Capterra 4.7, Trustpilot 4.4). EU-headquartered, 7-day free trial, 17% annual discount.
Frustrations: pricing emphasizes monthly cost but billed annually (top Trustpilot complaint). Trustpilot reviewer reported a $100 surprise charge after a single button press during trial. Like all click-fraud tools, capped by Google's negative-IP list (rolling 30-day expiry).
Wish List: true monthly billing without annual lock. Native Microsoft Ads parity.
Value for Money: 7.5/10. Solid mid-market pick with one of the broader feature bundles, just don't get caught by the annual fine print.
Pricing: from EUR 59/mo (~$69/mo) billed annually, 7-day free trial.
5. Click Guardian
The Good: cheapest credible click-fraud tool in this list at GBP 25/mo (GBP 20.83 + VAT) for one website after a 7-day free trial. UK-based human support, repeatedly called out as a differentiator. Set-and-forget once configured. Trustpilot reviewers report 5-10x ROI vs ad waste blocked.
Frustrations: multi-site pricing is a cliff (GBP 30 for 1 site jumps to GBP 75 for 2-3 sites). UK-only origin, less polished for Meta/Microsoft Ads. Smaller R&D budget than CHEQ/ClickGuard. Brand recognition lower outside UK.
Wish List: per-site pricing instead of the GBP 30 to GBP 75 cliff. Native Meta/TikTok blocking.
Value for Money: 7.5/10. Probably the highest-ROI fraud tool you can buy at small-to-mid scale UK Google Ads.
Pricing: GBP 25/mo (1 site), GBP 75/mo (2-3 sites), 7-day free trial.
Tier 2: mid-market and cross-channel fraud platforms
6. Lunio (formerly PPC Protect)
The Good: cross-channel intelligence across 15+ ad platforms (Google, Meta, TikTok, LinkedIn, X, Reddit, Snap, Pinterest). Detected on one platform, auto-excluded everywhere. ISO 27001 and SOC 2 certified. 35,000+ Google Ads accounts protected. G2 Leader in Click Fraud category. 14-day free traffic audit.
Frustrations: pricing starts at EUR 500/mo, pricey vs ClickPatrol/Fraud Blocker for SMB. Custom-quoted after the audit. UI feels enterprise-flavored to smaller shops. Long contracts and minimum-spend gating.
Wish List: self-serve monthly tiers under EUR 200. Deeper attribution-model integration with post-conversion fraud signals.
Value for Money: 7.5/10. Strongest mid-market pick for cross-channel click fraud. Priced out of small-budget shops.
Pricing: from EUR 500/mo custom quoted, 14-day free traffic audit.
7. TrafficGuard
The Good: 1 trillion+ data points monthly across paid search, social, mobile. Multi-channel breadth. Easy setup praised by agencies. Public ASX-listed parent (ASX:AV1) gives stability transparency.
Frustrations: percentage-based pricing (~2% of ad spend) gets ugly above $50K/mo. Support frequently criticized on Trustpilot/Capterra ("a bot that sends you to a help portal"). Data sometimes does not match Google Ads exactly. Missing native Facebook Ads integration in 2026.
Wish List: native Meta integration. Tiered flat pricing for $50K+/mo spenders.
Value for Money: 6.5/10. Solid for sub-$50K/mo, bigger spenders should price-shop hard.
Pricing: ~2% of ad spend protected, free tier up to $2,500/mo, custom enterprise quotes.
8. CHEQ (post-Deduce)
The Good: largest IVT/fraud detection player after acquiring ClickCease (2023) and Deduce (Jan 2025). Deduce identity graph covers 185M+ weekly active users with claimed 99.5% identity-assessment accuracy. Covers paid traffic IVT, on-site bot blocking, lead validation, AI-generated identity fraud. Trusted by Fortune 500s.
Frustrations: pricing fully opaque, enterprise sales motion only. Aggressive M&A pace creates product-integration risk. Multiple overlapping fraud SKUs to navigate. Marketing positioning shifted from click fraud to Go-To-Market Security to Intelligence Standard for the Human-AI Era in two years.
Wish List: clearer SKU map between Essentials, Paradome, and Deduce. Mid-market self-serve.
Value for Money: 7.5/10. Right pick for enterprise needing end-to-end fraud under one roof. Budget for sales calls.
Pricing: hidden, enterprise contracts only. SMB lives under ClickCease ($99-$349/mo).
Tier 3: enterprise bot defense and WAAP
These sit one layer up. Bot management and WAAP rather than click-fraud SaaS, but they catch the bots that hit your origin before they ever click an ad.
9. HUMAN Security (formerly PerimeterX merged in)
The Good: verifies 20T+ digital interactions weekly across 500+ global brands. Top scores on all 9 criteria in The Forrester Wave: Bot Management Software, Q3 2024. Unified Human Defense Platform spans bot defense, account protection, ad fraud, digital risk. Raised $50M+ in Oct 2024 (WestCap-led).
Frustrations: enterprise-only pricing, surges unpredictably with traffic spikes. Dashboard usability inconsistent. Documentation lags product velocity. Effectively zero SMB presence.
Wish List: predictable pricing tier. Documentation that keeps pace with releases.
Value for Money: 8/10. Category leader for enterprise bot/fraud defense. Six-figure budget.
Pricing: custom enterprise only, AWS Marketplace listings available.
10. DataDome
The Good: sub-2ms decisioning at the edge, ~5 trillion signals daily, claims to stop 350B+ attacks/year. Forrester Wave Leader in Bot Management 2024. Customers include Etsy, PayPal, SoundCloud. Low false positives on B2B ecommerce.
Frustrations: cost is the loudest complaint, expensive for smaller teams, bills spike with traffic surges. JS library prone to race conditions unless loaded extremely early. Minimum project sizes around $50K shut out SMB.
Wish List: predictable pricing tier or per-endpoint plan. Lighter-weight client SDK.
Value for Money: 8/10. Top-tier enterprise bot/fraud detection. Everyone else gets priced out.
Pricing: custom enterprise, no public tiers, ~$50K+ minimum project size.
11. Imperva
The Good: 9-time Gartner Magic Quadrant leader for WAAP. Behavioral ML adapts without manual rules. Full enterprise stack (WAF, Advanced Bot Protection, DDoS, API security, RASP, plus DAM under Thales). Mature on-prem/cloud/hybrid options.
Frustrations: pricing opaque, real WAF deployments start around $6K/mo. Post-Thales acquisition (Dec 2023) employee reviews flag bureaucracy and layoffs. Steep setup learning curve, false positives common until tuned. Wrong fit for SMB.
Wish List: published transparent pricing tiers. Lighter onboarding for mid-market.
Value for Money: 7.5/10. Right answer for enterprises with six-figure cybersecurity budgets, wrong tool for SMB analytics fraud.
Pricing: contact-sales custom. SMB floor ~$59/mo, App Protect ~$1K/mo, full WAF $6K+/mo.
12. Kasada
The Good: 60-95% reduction in bad-bot requests post-deployment. No CAPTCHAs, invisible client-side challenge keeps real users frictionless. Set-and-forget reputation. Mindshare jumped from 0.5% to 4.8% YoY in Gartner Bot Management category (Dec 2025).
Frustrations: pricing fully gated, no public tiers. Niche bot-only focus, no WAF or DDoS or fraud analytics. Smaller integration ecosystem than Imperva/Akamai/HUMAN.
Wish List: self-serve mid-market tier. Native fraud/ATO analytics dashboards.
Value for Money: 7.5/10. Cleanest pick if you only need bot defense and want to ditch CAPTCHA.
Pricing: custom-quote only, AWS Marketplace listing exists.
13. Shape Security (F5)
The Good: enterprise-grade bot defense protecting Fortune 500s. AI-driven detection using device + behavioral signals with zero CAPTCHA friction. Strong professional services bench. Backed by F5 (acquired 2020 for $1B).
Frustrations: opaque pricing, consumption-based via AWS Marketplace or sales. Adds latency through F5 cloud components. Mindshare slipped to 1.6% in May 2026 (from 1.9% YoY). Built for enterprise.
Wish List: public mid-market tier. Lower-latency edge deployment.
Value for Money: 7.5/10. Top-tier enterprise bot defense if you can stomach F5 sales cycles.
Pricing: not publicly disclosed. High five figures annually for enterprise deployments.
Tier 4: ad-tech verification and IVT measurement (different category)
These are for advertisers buying programmatic and brands measuring viewability. Not click-fraud SaaS for direct-response Google Ads buyers.
14. DoubleVerify
The Good: MRC-accredited across pre-bid avoidance, viewability, IVT. Native integrations with every major DSP/SSP. One stack for brand suitability + viewability + IVT.
Frustrations: Adalytics report (March 28, 2025) alleged DV billed customers for impressions to declared bots from known data center IPs. Stock crashed 36% in one day Feb 28, 2025. Securities class action filed for the Nov 2023-Feb 2025 window. April 2025 standard pre-bid rate card increased CPM rates during the credibility crisis.
Wish List: public transparent rate card. Pre-bid plus post-bid reconciliation matching third-party logs.
Value for Money: 6/10. Default agency-grade verification, but the 2025 lawsuit and stock crash put a permanent asterisk next to its IVT-detection claims.
Pricing: CPM-based, opaque. Typical buys $50K+ minimums.
15. Integral Ad Science (IAS)
The Good: MRC-accredited measurement. Pre-bid integrates with most major DSPs. Self-explanatory UI, easier than DoubleVerify. AI-driven low-quality AI content blocker (beta 2025).
Frustrations: cost not suitable for small business. High IVT/suitability fail rates reported despite using IAS pre-bid. Hit with class-action securities lawsuit (March 2025). Going-private under Novacap (Sept 2025, $1.9B) creates roadmap uncertainty.
Wish List: SMB-tier pricing. Transparency on decision-making when IVT slips through.
Value for Money: 6.5/10. Brand-side ad-verification standard built for Fortune 500 budgets.
Pricing: custom enterprise only.
16. Pixalate
The Good: strongest CTV/mobile-app IVT coverage. Q4 2025 benchmarks analyzed 103B impressions globally. MRC-accredited. Seller Trust Index 2.0 ranks 20+ CTV SSPs. Real-time fraud protection plus retroactive reports.
Frustrations: pricing not publicly disclosed. Heavily ad-tech focused, not a fit for first-party site analytics or e-commerce fraud. Reports skew research-output, less programmatic blocking automation. Sparse G2/Capterra reviews vs IAS/DV.
Wish List: published mid-market pricing. Stronger pre-bid blocking automation.
Value for Money: 7/10. Hard to beat in CTV/mobile programmatic, wrong shape for performance marketers.
Pricing: custom-quote only.
17. GeoEdge
The Good: 360-degree malvertising protection across Web, In-App, CTV. Blocklist updates land in hours. Customizable blocking by TLD, content category, keyword, app ID. Real publisher case studies (Evolve Media reported 80-90% reduction in malicious activity).
Frustrations: built primarily for publishers/SSPs, not direct-response advertisers worrying about Google Ads click fraud. No public pricing. Tiny G2 review surface. Real-time alert feature still missing.
Wish List: real-time alert/notification system. Self-serve plan with public pricing.
Value for Money: 7.5/10. Best-in-class for publisher ad quality and malvertising defense, irrelevant for click-fraud-on-Google-Ads use case.
Pricing: custom, contact sales. Free plan available for publishers.
Tier 5: niche, deprecated, or adjacent
18. Anura
The Good: 99%+ ad-fraud detection accuracy claimed. Unlimited free support (email, chat, phone) plus monthly training. Per-request pricing scales cleanly. Reviewers report annual cost paid back in 90 days.
Frustrations: pricing fully gated, contact sales only. Multiple G2/Capterra reviewers describe it as expensive. Less visible to SMB advertisers vs ClickCease/CHEQ. API-first, less polished than enterprise competitors.
Wish List: published pricing or self-serve tier. Native one-click connectors to Google/Meta/Microsoft.
Value for Money: 7.5/10. Pays for itself for high-volume affiliate/lead-gen, not the obvious Shopify pick.
Pricing: hidden, contact sales, per-request SaaS minimums.
19. Hitprobe
The Good: defensive analytics + click fraud protection in one product, rare bundle. Free tier up to 50 clicks/mo. Fingerprinting, IP analysis, behavioral signals. Multi-channel including dedicated PMax protection use case.
Frustrations: founded 2024, thin review base. Microsoft Ads support not yet shipped. Some report the analytics UI as fiddly. Entry plan ($80 for 10K sessions, 5 sites) more expensive per-session than pure click-fraud peers.
Wish List: Microsoft Ads native integration. Polished analytics UI.
Value for Money: 6.5/10. Promising new entrant blending privacy analytics with click-fraud defense, early adopter territory.
Pricing: free plan (50 clicks/mo), Growth 10 at $80/mo for 10K sessions, 5 sites.
20. Singular
The Good: voted best MMP on G2 (1,434+ verified reviews, 4.6/5 overall, 4.9 support). Fraud Prevention included in base price. Flexible pay model (ad spend or conversions). End-to-end ROI across mobile attribution + cost aggregation.
Frustrations: pricing custom and scales with installs. Functionality scores lag support scores. Pricing opaque on website. Mobile-only focus.
Wish List: published self-serve pricing for indie devs. Better web-side attribution.
Value for Money: 8/10. Most reviewer-loved MMP for mobile growth teams.
Pricing: free plan with limited features. Paid tiers custom-quoted.
21. Adverity
The Good: 600+ marketing/ads/CRM connectors with strong transformation engine. Dedicated marketing data focus including IVT/fraud signal layering. No-code data harmonization.
Frustrations: Azure Marketplace lists $200K upfront 12-month fee. G2 reviewers say it is getting quite expensive. Built-in visualization weak. Performance lags with very large datasets.
Wish List: published mid-market tier. Stronger native dashboarding.
Value for Money: 7/10. Best-in-class marketing-data ETL for agencies and mid-to-large enterprises with budget.
Pricing: hidden, demo + sales call required. Azure Marketplace lists $200K/year upfront.
22. PerimeterX (now HUMAN Bot Defender)
The Good: now part of HUMAN Security, combined entity ~$100M ARR, 500+ customers. HUMAN Bot Defender ranked #1 vendor in G2 Grid for Bot Detection. Strong observability/dashboards. Deep ATO and carding-attack coverage.
Frustrations: PerimeterX brand sunset, products renamed (Bot Defender, Code Defender). Customers report integration confusion post-merger. Setup complex with learning curve. Pricing high and gated.
Wish List: lower-friction onboarding without multi-week SE engagement. Transparent traffic-tier pricing.
Value for Money: 8/10. Category leader if bots/ATO are real revenue threats. SMBs keep walking.
Pricing: custom-quote only, subscription tied to traffic/request volume.
23. Forensiq
The Good: native suite inside Impact.com partner platform. Affiliate fraud detection wired into partner-payout flow. Four-suite coverage (Ad Verification, Firewall, Install, Performance). Real-time bot, cookie-stuffing, IVT detection.
Frustrations: only sold as part of Impact.com, hard to evaluate standalone. Public review surface thin (G2 stale since 2019). Better-known for affiliate than general PPC click-fraud.
Wish List: standalone Forensiq SKU. Public current pricing.
Value for Money: 6.5/10. No-brainer if you already run Impact.com. No reason to start here otherwise.
Pricing: custom enterprise inside Impact.com. Older listings cite ~$100/user/mo (2021, likely stale).
24. PPC Protect
The Good: original UK click-fraud pioneer founded 2016. Same team, IP, and tech now operating as Lunio. Successful pivot story: rebrand backed by GBP 14M Series A (Smedvig Capital, 2022).
Frustrations: brand officially retired. Searching PPC Protect in 2026 redirects to Lunio. Some legacy customers reported contract/migration confusion. Capterra listing fragments reviews across two product pages.
Wish List: cleaner consolidation of legacy review pages under Lunio. Clear archival page for procurement teams.
Value for Money: 6.5/10. Do not evaluate as a separate product. PPC Protect became Lunio in Sept 2022, same company, same product, new name.
Pricing: N/A. Product is Lunio. Lunio starts ~EUR 500/mo.
25. Moat
The Good: was historically the gold-standard for viewability and engagement measurement after Oracle's 2017 acquisition (~$850M). MRC-accredited across video viewability, attention, brand safety while operational. Strong panel-driven attention metrics.
Frustrations: product is dead. Oracle shut down Moat and the entire Oracle Advertising business on September 30, 2024. Customers had ~3 months from June 2024 announcement to migrate. All historical Moat data, dashboards, integrations went dark.
Wish List: there is no roadmap. The only meaningful wish is for someone to acquire the IP and revive panels.
Value for Money: 2/10. Do not include in 2026 evaluations. Treat any reference as historical only.
Pricing: discontinued.
Tier 6: trust infrastructure (the conversion-side wedge)
26. DataCops
This is not a like-for-like ClickCease swap. It is the layer underneath that filters fraud on the conversion side rather than the click side. The piece every other ranking page in this category leaves out.
The Good: 361,873,948,495+ IPs and ranges in the reputation database (202B+ residential, 146.4B+ datacenter, 11.9B+ VPN, 620M+ proxy). Fraud Traffic Validation runs on 350+ continuous monitoring points and categorizes traffic in real time (real human, datacenter, residential, VPN, proxy, blacklisted) before events hit analytics or CAPI. Server-side CAPI to Meta, Google, TikTok, LinkedIn gates fraud out of the conversion signal Smart Bidding learns from. CNAME-based, ad-blocker immune. SignUp Cops adds IP intelligence + browser fingerprint + email validation at the form. Free tier 2,000 sessions per month, no card.
Frustrations: SOC 2 Type II in progress, not done. Google Consent Mode v2 enforcement in progress. SSO/SAML planned. Brand-new in this category, fewer third-party reviews than ClickCease/Lunio. PMax management still constrained by Google's API restrictions like every other tool.
Wish List: SOC 2 Type II. SSO/SAML. DSAR API plus downstream deletion (Meta, Google).
Value for Money: 8.5/10. Right answer if you want fraud filtering plus consent plus first-party analytics plus CAPI from one vendor at SMB pricing.
Pricing: Basic free (2K sessions), Growth $7.99/mo (5K sessions, unlimited Meta and Google CAPI), Business $49/mo (50K sessions, HubSpot integration), Organization $299/mo (300K sessions), Enterprise talk to sales (dedicated environment, dedicated IP database, custom DPA, EU/US residency).
So what should you actually use?
Want the cheapest credible UK Google Ads click-fraud tool? Try Click Guardian.
Want the cheapest US-friendly SMB tool with one of the broadest feature bundles? Try ClickPatrol or Fraud Blocker.
Want power-user click-rule depth and AI cross-channel reporting? Try ClickGuard.
Want cross-channel coverage across Google + Meta + TikTok + LinkedIn + 11 more? Try Lunio.
Want enterprise bot defense at the WAAP layer because your origin is under attack? Try HUMAN, DataDome, Imperva, or Kasada.
Want programmatic ad-verification with MRC accreditation? Try IAS or DoubleVerify, but read the 2025 lawsuit dockets first.
Want CTV and mobile-app IVT measurement? Try Pixalate.
Want conversion-side filtering that survives PMax's API lock-out, plus consent plus first-party analytics from one vendor? Try DataCops underneath whatever click-side tool you already run.
The mistake I see people make
Treating click-side IP blocking as the whole job. The Feb 2026 Fraud Blocker benchmark shows PMax at 12.1% IVT, Smart at 28.6%, Display & Video at 35.5%. None of those surfaces are reachable by third-party click-side tools because Google blocks API access to PMax management. The waste is real and the click-side tools cannot touch it.
The layer that survives is conversion-side. Filter fraudulent conversions before they reach Smart Bidding via Enhanced Conversions or server-side CAPI. Bad conversions train bad bid models. Bad bid models compound waste across the whole account. Click-side wins on IP blocking. Conversion-side wins on signal hygiene. Both layers belong in a 2026 stack.

Now your turn
Which layer is leakier in your account right now, the click side (IPs you cannot reach to block) or the conversion side (fraud signals training Smart Bidding)?
