Trigger Events Using HTML or via Page URLs

By tagging HTML elements with predefined PixelFlow classes, you can:

Track User Actions Precisely - PixelFlow will fire tracking events automatically when users interact with your tagged elements, such as clicking buttons or submitting forms, without any extra JavaScript logic.
Capture Conversions That Don’t Reload Pages - Some websites use dynamic interactions or embedded forms where traditional URL-based tracking falls short. Event Classes let you catch those clicks and submits wherever they happen in your HTML.
Enrich Events With User Data - When you tag form input fields with special PixelFlow classes, PixelFlow extracts values like name, email, and phone, hashes them for privacy, and includes them with the event payload. This dramatically improves match quality and ad attribution.

The bottom line - PixelFlow enhances CAPI tracking on any HTML website (or Javascript, React etc.) by making it simple, accurate, and resilient in a way that anyone can use it.

Marketers typically see:

improved conversion capture,
higher event match quality,
better ad optimization,
clearer attribution,with far less manual engineering required.

If your goal is maximizing Facebook/Meta ad performance with clean, complete data, PixelFlow delivers a powerful and simple to use way to trigger events and enrich them via your website or app

  <!-- Customer information -->
  <input type="text" class="info-cust-full-name-pf" placeholder="Full Name" />
  <input type="email" class="info-cust-em-pf" placeholder="Email" />
  <input type="tel" class="info-cust-ph-pf" placeholder="Phone (optional)" />

  <!-- Message fields -->
  <input type="text" placeholder="Subject" />
  <textarea placeholder="Your message..."></textarea>

  <!-- Submit button -->
  <button type="submit" class="action-btn-cntct-003-pf">Send Message</button>

</form>

How it Works - Simple & Flexible

Install PixelFlow Script - Add the PixelFlow tracking script to your HTML <head> so that PixelFlow can listen for class-based events.
Add Event Classes to Elements - Simply include PixelFlow’s pre-defined classes in your element’s class attribute like this:

<button class="btn btn-primary action-btn-sub-002-pf">Subscribe Now</button>

In the example above, when clicked, PixelFlow will send a subscribe event to Meta along with any additionally captured metadata like name, email address etc.

With this setup, PixelFlow handles all event triggering automatically with no custom JavaScript required.

Frequently Asked Questions

1. What are PixelFlow Event Classes for HTML websites?

PixelFlow Event Classes are pre-built CSS class names you add to your HTML elements (like buttons, forms, and inputs) to trigger tracking events automatically. This makes it easy to track conversions and user actions without writing custom JavaScript.

2. Do I need to know JavaScript to use PixelFlow Event Classes?

No. PixelFlow Event Classes are designed to be simple and lightweight. As long as you can edit your HTML and add a class to an element, you can track events like clicks and form submissions—without coding a full tracking script.

3. What actions can I track on an HTML site with PixelFlow?

With PixelFlow Event Classes, you can track key interactions such as:

Button clicks (CTAs, signups, downloads)
Form submissions (leads, contact forms, newsletters)
Search interactions
Link clicks and custom engagement events

This helps you measure what visitors actually do—not just which pages they view.

4. Can PixelFlow track form submissions on plain HTML websites?

Yes. PixelFlow can track HTML form submissions by tagging the form and/or submit button with the correct event class. This is perfect for tracking lead generation forms, newsletter signups, and contact forms on static sites.

5. Can PixelFlow capture user data like email or phone from HTML forms?

Yes. PixelFlow supports tagging form input fields so it can collect values like email, phone, and name and use them to improve event quality. This is especially useful for better attribution and stronger match rates in ad platforms.

6. Does PixelFlow work on static sites and landing pages?

Yes. PixelFlow Event Classes work great for:

Static HTML websites
Landing pages
Microsites
Custom-coded marketing pages
Sites built with static site generators

If you can edit the HTML, you can implement PixelFlow tracking.

7. How is PixelFlow Event Class tracking different from traditional pixel tracking?

Traditional pixel tracking often relies on page loads or manual JavaScript events. PixelFlow Event Classes let you track interactions directly on elements (like clicks and form submits), which is more reliable for modern landing pages where conversions don’t always trigger a new page load.

8. Who should use PixelFlow Event Classes on an HTML website?

PixelFlow Event Classes are ideal for:

Marketers who want conversion tracking without complex setup
Developers who want a fast, clean tracking method
Businesses running paid ads to HTML landing pages
Teams that need better visibility into button clicks and form conversions

If you want better tracking with minimal effort, Event Classes are a perfect fit.
