Example: If this is the thank you page link, https://webinarkit.com/webinar/thankyou/664de98c0b8cff4472266f26?t=1769929170458

Take note that whatever is after ? is dynamic. which means it is different for every client based on the time that they registered for the webinar. Therefore you should do:

How to Install the Meta Pixel on WebinarKit

This guide will show you how to install the Meta Pixel on WebinarKit, create a Custom Conversion, and optimise your Facebook ads for webinar registrations.

Step 1: Open Facebook Ads Manager

Go to:

Facebook Ads Manager

facebook.com/adsmanager

If you don't already have a Meta Pixel:

1. Click the ☰ (Menu) button.

2. Under Manage Business, click Events Manager.

Or go directly to:

Facebook Events Manager

facebook.com/events_manager

Step 2: Copy Your Meta Pixel

1. In Events Manager, select your Meta Pixel.

2. Click Add Events.

3. Choose From a New Website.

4. Select Install Code Manually.

5. Copy the entire Meta Pixel base code.

Step 3: Install the Pixel on All WebinarKit Pages

1. Log in to WebinarKit.

2. Open your webinar.

3. Install the Meta Pixel on every page of your webinar funnel.

For each page, navigate to:

Settings → Page Header Scripts

Paste your Meta Pixel base code into the Page Header Scripts section and click Save.

Repeat this for all of the following pages:

• Registration Page

• Thank You Page

• Watch Room (Live Webinar) Page

• Replay Page

Installing the Meta Pixel on every page allows Facebook to track visitors throughout your entire webinar funnel, including:

• Visiting your registration page

• Completing their registration

• Attending the live webinar

• Watching the replay

This also allows you to create more advanced Custom Audiences and retargeting campaigns in the future.

Step 4 (Optional): Verify Your Pixel Installation

Before creating your Custom Conversion, it's a good idea to confirm that your Meta Pixel is firing correctly.

Install the Meta Pixel Helper Chrome extension:

Meta Pixel Helper (Chrome Web Store)

After installing:

1. Open any of your WebinarKit pages.

2. Click the Meta Pixel Helper icon in your Chrome toolbar.

3. Confirm that your Meta Pixel is detected.

4. You should see a PageView event with no errors.

If you see your Pixel firing successfully, you're ready to move on.

Step 5: Create a Custom Conversion

Go back to:

Facebook Events Manager

facebook.com/events_manager

1. Select your Meta Pixel.

2. Click Custom Conversions.

3. Click Create Custom Conversion.

Configure it as follows:

Conversion Name

Visited TY Page

Conversion Event

All URL Traffic

Rule

Choose:

URL contains

For example, if your Thank You page is:

https://webinarkit.com/webinar/thankyou/664de98c0b8cff4472266f26?t=1769929170458

Take note that everything after the ? is dynamic and changes every time someone registers.

Therefore, do not use the full URL.

Instead, configure the rule as:

URL contains

https://webinarkit.com/webinar/thankyou/664de98c0b8cff4472266f26

Facebook will ignore the changing query string and correctly count every webinar registration.

Category

Select:

Lead

Click Create.

Why Do We Use the Thank You Page?

We use the Thank You page because it is only shown after someone has successfully completed the webinar registration form.

This means:

• If someone only visits the Registration Page, they are not yet a lead.

• Once they submit the registration form, WebinarKit redirects them to the Thank You Page.

• Therefore, anyone who reaches the Thank You Page has successfully become a lead.

By creating a Custom Conversion based on visits to the Thank You Page, you're telling Meta:

"Count everyone who reaches this page as a successful lead."

This gives Facebook a much more accurate signal than simply optimising for page views or link clicks. Over time, Meta's algorithm will learn to find people who are more likely to complete your webinar registration and reach the Thank You Page, helping improve your lead quality and campaign performance.

Since WebinarKit appends a dynamic timestamp to the Thank You Page URL, you'll use URL contains (without the dynamic portion after the ?) so that every successful registration is tracked correctly.

Step 6: Use the Custom Conversion in Your Campaign

Return to:

Facebook Ads Manager

facebook.com/adsmanager

When creating or editing your campaign:

1. Choose your campaign objective (Sales or Leads).

2. Under Conversion Location, select Website.

3. Select your Meta Pixel.

4. Under Conversion Event, choose:

Visited TY Page

Facebook will now optimise your ads for people who successfully reach your WebinarKit Thank You page instead of simply clicking your ad.

Once this setup is complete, Meta will be able to accurately track webinar registrations and optimise your campaigns for people who successfully register, while also collecting valuable data across your entire WebinarKit funnel for future retargeting and audience building.
