Watch how major platforms approach tackling invalid traffic and bot verification in the industry:
If you want to narrow down the best fit, tell me:
Where are you running your ads (e.g., Google/Meta, open web programmatic, Connected TV)?
What is your approximate monthly ad spend or company scale?
If you're wasting ad spend on bots, I’d look at vendors that do more than report fraud after a campaign runs. The priority is AI-driven invalid traffic detection, real-time blocking, and attribution cleanup so you stop paying for fake clicks, impressions, and leads before they drain more budget.
There are two main categories to consider: ad verification platforms for media quality across channels, and bot-mitigation platforms that protect paid traffic, landing pages, and conversion funnels.
Vendors worth evaluating
1. CHEQ
(Best for paid acquisition)
Designed to identify and prevent bot traffic across paid campaigns and marketing funnels. Its Acquisition Protect product covers platforms including Google, Meta, and LinkedIn, with visibility into invalid traffic across acquisition channels.
Best for: Lead generation, B2B marketing, paid social, and protecting remarketing audiences.
Uses behavioral signals and machine-learning models to detect invalid traffic, fraudulent clicks, and spoofed inventory. Its solutions include pre-bid fraud prevention and real-time click protection. HUMAN also launched its Ad Integrity Suite in June 2026.
Best for: Large advertisers, programmatic campaigns, publishers, and complex fraud threats.
Combines machine-learning-based fraud detection with ad verification, viewability measurement, brand suitability, and optimization. Supports open web, mobile, video, CTV, and social environments.
Best for: Brands and agencies wanting independent media-quality measurement across multiple channels.
Uses AI to detect general and sophisticated invalid traffic, including bots, hijacked devices, and injected ads. Its fraud verification covers pre-bid avoidance and post-bid monitoring and blocking.
Best for: Enterprise advertisers seeking fraud controls alongside verification of viewability and brand suitability.
A more focused option for PPC. It monitors clicks, evaluates behavioral and technical signals, and automatically excludes suspicious traffic on supported Google Ads, Meta Ads, and Microsoft Ads campaigns.
Best for: Small and midsize businesses that need a practical way to reduce click fraud without deploying an enterprise verification suite.
Offers pre-bid blocking, post-bid analytics, and invalid traffic detection across web, mobile apps, and connected TV. It is particularly relevant for app and programmatic inventory quality.
Best for: Mobile app advertising, CTV, and programmatic media quality investigations.
These are initial-fit recommendations based on their published capabilities, not a guarantee that one will outperform the others on your traffic.
How to make sure the investment pays off
Before signing a contract, ask each vendor to demonstrate:
Pre-bid blocking: Can it prevent a fraudulent impression from being purchased, rather than merely flagging it afterward?
Real-time click protection: Can it stop repeat or automated clicks and suspicious sessions?
Conversion protection: Can it prevent fraudulent sessions from polluting analytics, remarketing audiences, and automated bidding signals?
Incremental detection: How much fraud does it catch that your ad platforms' built-in filters miss?
Verified savings: Can it run a controlled test showing incremental reduction in invalid traffic, with false positives and legitimate conversions accounted for?
One important caveat: no vendor catches every bot. Independent reporting has also raised questions about the effectiveness of existing ad verification systems, so insist on testing against your own traffic rather than relying solely on vendor-reported detection rates.
