Install

No release zip yet. The repository archive installs, but the folder name will carry the branch suffix and updates will not flow:

wp plugin install https://github.com/sourcetagio/wp-plugin/archive/refs/heads/main.zip

Ships its own WordPress updater (Plugin Update Checker), so new versions show up under Dashboard → Updates.

Readme github.com/sourcetagio/wp-plugin ↗

SourceTag WordPress Plugin

Tracks where your leads come from. Captures UTM parameters, click IDs, referrer data, and landing pages in your form submissions.

What it does

  • First-click and last-click attribution
  • 400-day cookie persistence via server-side cookies (gets around Safari's 7-day JS cookie limit)
  • Works with Contact Form 7, Gravity Forms, WPForms, Elementor Forms, HubSpot Forms, and any HTML form
  • You just need to add hidden fields to your forms — the plugin populates them

Install

  1. Download the latest .zip from Releases
  2. In WordPress: Plugins > Add New > Upload Plugin
  3. Upload and activate
  4. Go to Settings > SourceTag and paste your Script URL from the SourceTag dashboard

Full setup guide: sourcetag.io/docs/install-wordpress

How it works

The plugin loads the SourceTag tracking script in your <head> and re-sets the attribution cookie via PHP setcookie() on each page load. This extends cookie life from 7 days (Safari's JS limit) to 400 days.

There's also a REST endpoint (/wp-json/sourcetag/v1/set-cookie) that the script calls on a visitor's first visit to set the cookie before the PHP refresh kicks in.

Requirements

  • WordPress 5.8+
  • PHP 7.4+
  • A SourceTag account (sourcetag.io)
