Connect Google Analytics 4 to your CRM with Heeet

You need both, and they do different jobs. GA4 stays your source of truth for website behavior: page views, scroll depth, video engagement, traffic sources. Heeet stays your source of truth for revenue attribution: which channels, campaigns, and content actually drove pipeline and closed deals. Heeet pulls GA4 session data into Salesforce or HubSpot and pushes CRM conversion events back to GA4, so both platforms get smarter together. You don't have to pick one or the other.

You can fire a GA4 event when a form submits, either through Google Tag Manager, the GA4 Measurement Protocol, or HubSpot's native GA4 integration. The bigger problem is connecting that event back to the contact record so you can track everything that happens after the form fill. Heeet captures the GA4 client ID and session ID at the moment of form submission and writes both to the Salesforce or HubSpot contact record automatically. From there, every campaign, opportunity, and revenue event ties back to the original GA4 session.

GA4 defaults to data-driven attribution and offers six models total: data-driven, last click, first click, linear, time decay, and position-based. Each one credits touchpoints differently, but all of them only see what happens inside GA4. For B2B teams with sales cycles longer than 90 days, that's a problem. Most opportunities involve sales-led touches, dark social, and offline conversations that GA4 will never capture. Heeet runs multi-touch attribution against the full CRM record, including non-digital touches, so you get a more complete picture than any GA4 model alone can give you.

GA4 is a web analytics platform built for tracking sessions, events, and clicks on your website. It uses last-click and data-driven attribution models that look at touchpoints captured in GA4 only. CRM attribution tools like Heeet use the contact and opportunity records as the source of truth, which means they can attribute revenue across every channel — paid, organic, content, email, events, even sales-led outreach. Heeet doesn't replace GA4. It uses GA4 session data as one input alongside your CRM pipeline, then runs multi-touch attribution against actual closed-won revenue.

Offline conversions are revenue events that happen in your CRM after the form fill — an MQL upgrade, a new opportunity, a closed deal. GA4 has a Measurement Protocol API that accepts these events, but most teams don't have the engineering capacity to wire it up. Heeet automates the full loop. You define the conversion conditions in your CRM (Lead Created, MQL, SQL, Opportunity, Closed-Won, Opportunity Amount), and Heeet pushes those events back to GA4 every hour with the original session ID attached. GA4 sees the full journey from session to revenue.

GA4 was built to track website behavior, not revenue outcomes. It tells you who visited, what they clicked, and whether they hit a conversion event like a form submission. It can't tell you whether that form submission became an MQL, an opportunity, or a closed deal — because that data lives in your CRM, not in GA4. Heeet bridges the two by capturing the GA4 session ID at the moment of form submission and storing it on the Salesforce or HubSpot contact record. From there, every CRM milestone (MQL, SQL, Opportunity, Closed-Won) ties back to the original session.

GA4 doesn't ship with a native Salesforce or HubSpot integration. You can pipe GA4 data into BigQuery and build a custom warehouse pipeline, use a generic ETL tool like Funnel.io or Fivetran, or use a CRM-native attribution tool like Heeet. Heeet captures GA4 session identifiers, UTM parameters, and referral data on every website visit, then attaches them to the matching Lead, Contact, and Opportunity in your CRM. Setup takes under five minutes through a secure OAuth connection. No BigQuery, no developers, no manual tagging.
