Lunio

In short: Lunio is click fraud protection and analytics software, with enterprise pricing.

Detects and blocks invalid clicks across paid search, social and display campaigns

Lunio is ad traffic verification software that detects and blocks invalid clicks on paid media. It was previously known as PPC Protect and is aimed at in-house paid media teams and agencies managing significant ad spend.

A machine learning engine scores each click as legitimate, suspicious or invalid using click, context and conversion data. Analytics break down invalid traffic by campaign, keyword, placement and location, drawing on data from the Google Ads API. Lunio excludes invalid IP addresses at campaign and account level and, where IP blocking is not available, builds exclusion audiences instead. It covers paid search, paid social, display, Performance Max and affiliate traffic on Google Ads, Microsoft Advertising, Meta and other platforms. The tracking is cookieless, built for GDPR and CCPA compliance and designed not to slow pages down.

Pricing is set per customer as a small share of ad spend, depending on spend and channel coverage. A 14 day free traffic audit gives access to the full analytics before pricing is agreed, and customer success managers support accounts.
