Frequently asked questions
Common questions about switching from Google Tag Manager + GA4 to LeadToSheet.
- Why use LeadToSheet if I already track form submissions in GA4 through GTM?
- GA4 aggregates events into reports - you can see how many submissions happened, but not who submitted what. LeadToSheet stores the per-submission detail (name, email, message, UTMs, click IDs) as individual rows in Google Sheets, which is what you actually need to follow up on a lead.
- Can I run LeadToSheet alongside GTM/GA4?
- Yes - they don't conflict. Most teams keep GA4 for aggregate analytics and add LeadToSheet to capture the actual lead data into Sheets. No GTM container changes required.
- Do I need to configure custom triggers and variables for each form like in GTM?
- No. LeadToSheet auto-detects and fingerprints every form on the site - new forms work the moment they ship without touching the script. GTM requires per-form triggers, variables, and tags that need re-mapping when the form changes.
- What if I want the data in BigQuery instead of Sheets?
- Submissions are also exposed via webhook and the dashboard API, so you can pipe them into BigQuery, your warehouse, or any CRM. Sheets is just the default destination because it's where most teams start.
