Google Ads Conversion Tracking for WordPress Forms – TagFlux

Description

TagFlux is a server-side Google Ads conversion tracking plugin for WordPress forms. It auto-detects the forms already installed on your site, lets you choose which submissions count as conversions, and sends them to Google Ads through the TagFlux backend using the Google Click Identifier (gclid) — no code, no Google Tag Manager, no manual event setup.

Server-side Google Ads conversion tracking for WordPress

TagFlux uses server-side conversion tracking to send WordPress form submissions to Google Ads through the TagFlux backend.

When a visitor arrives from a Google Ads click, TagFlux stores the Google Click Identifier (gclid) in a first-party cookie. If that visitor submits a tracked WordPress form, TagFlux sends the conversion event to Google Ads through the backend instead of relying only on browser-side tags.

This is useful for lead generation websites that want more reliable Google Ads conversion tracking without maintaining a custom Google Tag Manager or gtag setup.

Why TagFlux instead of Google Tag Manager?

Setting up Google Ads conversion tracking by hand usually means editing gtag snippets, configuring triggers in Google Tag Manager, and testing events one by one.

TagFlux skips the manual tag setup. It detects your WordPress forms, captures the Google Click Identifier (gclid), and reports form submissions to Google Ads server-side through the TagFlux backend using the Google Ads API.

That means no GTM container to maintain, no custom JavaScript, no manual event setup, and fewer moving parts between your WordPress forms and Google Ads conversion actions.

Supported form plugins

TagFlux currently supports:

• Contact Form 7
• WPForms
• Elementor Pro Forms
• Ninja Forms
• Divi Forms

If your Google Ads traffic lands on a WordPress page using one of these form plugins, TagFlux can help track those form submissions as Google Ads conversions.

How it works

1. Install and activate the plugin — activation contacts no external service.
2. Click «Connect to TagFlux» and connect your Google Ads account via OAuth.
3. Select which forms to track. From then on, every submission is sent to Google Ads as a conversion automatically.

External services

This plugin connects to two external services to provide conversion tracking. It does not work without them.

1. TagFlux backend (api.tagflux.io)

TagFlux relays conversion data to Google Ads through its own backend.

• When you connect the site: activating the plugin sends nothing. Only after you explicitly click «Connect to TagFlux» on the plugin settings screen does it send this site’s URL and name to https://api.tagflux.io/api/auth/register to register the site and obtain an API key. No personal data is sent at this step.
• When a tracked form is submitted: it sends a Google Click Identifier (gclid/wbraid/gbraid, stored in a first-party cookie tagged as marketing), the visitor’s Consent Mode v2 state, an order ID used for deduplication, the form/campaign identifiers and the conversion event to https://api.tagflux.io. The contents of the form fields (names, emails, messages) are not sent — with one exception: if you enable the optional Enhanced Conversions setting and the visitor has granted ad consent, the email and/or phone number from the submitted form are sent as SHA-256 hashes (never in plain text).

2. Google Ads / Google OAuth

To connect your Google Ads account the plugin uses Google’s OAuth flow, and the backend reads/writes conversion data via the Google Ads API on your behalf.
