PostHog

How it works

1. 1

   Create a personal API key

   In PostHog, create a personal API key named “1DB” and give it Query read access.

2. 2

   Add the key and project

   Pick your PostHog region (US, EU or a self-hosted address) and enter the ID of the project that receives your sites’ pageviews.

3. 3

   Traffic is matched by domain

   Pageviews are grouped by host, so each website’s traffic lands on its own row, refreshed every hour.

Good to know

One project for every site

All your sites can report to the same PostHog project. 1DB tells them apart by domain.

Traffic next to leads

Seeing visits and leads side by side shows which sites convert and which have a form that stopped working.

Guides

• Guide·Capture leads

  Capture UTM parameters and ad click IDs in form submissions

  Keep the campaign that brought a visitor, even after they’ve browsed three pages before filling in your form, and store it on the lead.
