Real User

Detailed explanation

A Real User refers to a genuine human visitor generating one or more visits to a site, as opposed to traffic generated by bots, crawlers, scrapers, or other automated, non-human sources. The distinction matters because raw traffic and impression logs capture all of this activity indiscriminately, while advertisers and site owners are ultimately paying for, and trying to reach, actual people.

Ad verification and analytics tools use a combination of signals — browser and device fingerprinting, behavioral patterns like mouse movement and scroll behavior, known bot IP ranges, and industry bot-detection lists (such as those maintained by the IAB) — to filter non-human activity out of reporting and produce a real-user count that better reflects genuine audience size and ad exposure.

This filtering is directly tied to ad fraud prevention: invalid traffic (IVT), whether from simple bots or more sophisticated fraud schemes, inflates impressions and clicks without any real user behind them, which wastes advertiser budget and distorts performance reporting. Distinguishing real users from all other traffic is therefore a foundational requirement for trustworthy measurement, not just a nice-to-have refinement.
