HYROS is a server-side attribution platform for ad accounts. GA4 is a website analytics platform. They're different tools that serve different purposes — but most businesses need both for complete attribution tracking.
This guide covers the key differences, when to use each, their costs, iOS 14 attribution, and whether you should use both together.

Use HYROS if you're running paid ads (Google Ads, Facebook Ads, TikTok) and need accurate attribution. HYROS is specifically built to solve the iOS 14 attribution problem that breaks Facebook Pixel and GA4.
Browser-based pixels miss 40–60% of iOS conversions. HYROS recovers these with server-side tracking.
HYROS shows you true ROAS by linking ALL conversions to ad clicks — not just browser-tracked ones.
If you're spending $5K–$500K/month on ads, accurate attribution directly improves your ROI.
HYROS links phone calls, bookings, and other offline actions back to the ad that triggered them.
Use GA4 if you need to understand HOW users behave on your website. GA4 shows user journeys, content engagement, and conversion funnels — data HYROS cannot provide.
GA4 shows which pages users visit, how long they stay, what content they engage with, and where they drop off.
Identify technical issues — broken links, slow pages, form submission failures — through conversion tracking.
GA4 shows which blog posts, product pages, and landing pages convert best.
Understand your users — demographics, interests, devices, geography — to improve targeting.
If you're running Google Ads, Facebook Ads, or TikTok Ads and want accurate ROI, you NEED both:
If you only use GA4:
30 minutes. No pressure. Just clarity on your analytics.
