We’re thrilled to announce a brand-new feature: Meta Pixel Integration is now available on Mainstack!

With this update, you can easily add Meta Pixel (formerly Facebook Pixel) to your Mainstack page to track conversions, measure ad performance, and optimize your marketing campaigns across Facebook and Instagram.

If you use Mainstack to promote your products, digital services, or affiliate offers, this new feature helps you understand your audience better and turn every click into a conversion.

What Is Meta Pixel Integration and Why It Matters

The Meta Pixel is a powerful analytics tool from Meta (formerly Facebook) that helps you understand what happens after people visit your page. When you connect it to your Mainstack Storefront or Hosted Course, you unlock a new level of insight into how your visitors engage, click, and convert.

Here’s what it helps you do:

  • Track conversions that matter: See exactly how many people click your links, sign up for your course, or complete a purchase on your Mainstack page.
  • Measure your ad results: Know which Facebook or Instagram ads are actually driving traffic and sales, not just impressions.
  • Retarget your visitors: Reconnect with people who viewed your page but didn’t buy or sign up and bring them back with the right ad.
  • Optimize ad delivery automatically: Meta’s algorithm uses your pixel data to find more people like your best customers, so your ads convert better over time.

With Meta Pixel integration on Mainstack, you can finally see the full picture without using multiple tools or complicated setups. It’s everything you need to run smarter ads, understand your audience, and grow faster, all in one place.

Setting up Meta Pixel on Mainstack takes just a few minutes. Here’s how to do it:

Step 1: Find your Meta Pixel ID
