Hyros

Overview

Hyros is an ad tracking and attribution platform designed for high-spend advertisers, media buyers, and direct response marketers. The platform specializes in click-level attribution — connecting individual ad clicks across platforms like Meta, Google, YouTube, and TikTok to downstream conversions, often across long and complex customer journeys that span multiple touchpoints over days or weeks.

What This Script Does

Hyros's tracking scripts are deployed on landing pages, sales pages, opt-in forms, and post-conversion thank-you pages. On initial page load, the script reads URL parameters from inbound ad clicks (such as UTM parameters, click IDs from Meta's fbclid, Google's gclid, and similar platform-specific identifiers) and stores them in cookies and browser storage to establish the attribution chain.

A persistent first-party cookie assigns each visitor a unique Hyros identifier that persists across sessions. This allows the platform to connect a visitor's first ad click to a conversion that may occur days or weeks later, even across different devices if the user authenticates on both. The script fires conversion events at key points in the funnel — lead capture form submissions, application completions, calls booked, purchases made, and subscription activations — and transmits these events to Hyros servers tagged with the originating ad click data.

Hyros also supports phone call tracking through dynamic number insertion, where the script replaces phone numbers on the page with trackable numbers that tie inbound calls back to the ad click that brought the visitor.

The collected data feeds into Hyros's attribution reporting, which media buyers use to determine true return on ad spend and reallocate budgets to the highest-performing campaigns and creatives.

Consent & Compliance

Hyros is advertising attribution technology. Its scripts exist to track individual visitors across sessions, link their behavior to specific ad clicks, and measure advertising ROI. This involves persistent cookie-based tracking, cross-session identity resolution, and behavioral event collection — all of which require informed consent under GDPR, ePrivacy, and similar regulations.

The tracking serves the advertiser's optimization needs. Visitors receive no direct benefit from Hyros running in their browser, and the persistent identification of individual users across sessions raises significant privacy considerations that necessitate consent.

Should You Block This Without Consent?

Yes. Hyros performs persistent advertising attribution tracking that requires visitor consent before any scripts are loaded.
