Common questions for Facebook Conversion Leads

How to set up Facebook Conversion Ads using Lead Ads?

To set up Facebook Conversion Ads using Lead Ads, follow these straightforward steps:


  • Step 1: Open Facebook Business Manager and go to Ads Manager.
  • Step 2: Select "Lead Ad" as your Facebook Ad objective, and create the ad as usual until you reach the Delivery section.
  • Step 3: In the "Optimization & delivery" section, choose what you want to prioritize.
  • Step 4: Ensure "Conversions" is selected (if not the default) to enable Conversion Leads Optimization.
  • Step 5: Add a "Cost per result goal" to specify the desired average CPA. This helps you stay within budget.

Note: Before diving into the optimization process, make sure to set up Facebook Conversions API if you haven't already. This is crucial as it allows the gathering of performance feedback and enhances targeting through Facebook's powerful machine-learning capabilities.


What is the difference between Facebook Lead Ads vs. Conversion Ads?

The main difference between Facebook Lead Ads and Conversion Optimization Ads lies in their focus. Facebook Lead Ads prioritize generating a high volume of leads by showing your ad to people in your target audience who are likely to contact you. It emphasizes quantity. 


On the other hand, Conversion Optimization Ads prioritize the quality of leads. Instead of simply reaching as many people as possible who may fill out the lead form, it aims to target individuals who are most likely to become actual customers. This approach focuses not only on the number of completed lead forms but also on driving qualified leads who have a higher potential of progressing through the sales funnel.

How can I retrieve the events I need from my CRM for this optimization?

Situations are all different. It depends on which CRM you’re using and on the particular workflows that your business has in place. Sales are not made in the same way in every business. Don't hesitate to reach out to us if you need guidance setting up this integration.

What is the CRM Integration?

The Facebook CRM integration is a way to retrieve events from a CRM and send them via CAPI. According to Facebook, CRM Integration can be performed either manually (with internal technical support) or with the help of a partner (such as LeadsBridge).


With the CRM integration, the only valid leads that will be considered for the Conversion Leads optimization are leads that come from Facebook. In other words, leads generated with a Facebook Lead Generation paid campaign, ones that have a Facebook Lead ID. In fact, all leads generated, for instance, on a Web form or that come into the CRM from sources that are not Facebook campaigns, will not be considered for the Conversion Leads optimization.

How to check that my campaign is using Conversion Leads Optimization?

Once all of this has been done, you should follow the steps listed at Meta’s Business Help Center and make sure to:


  • Configure the Pixel you used in LeadsBridge as a CRM connection.
  • Set up the Sales Funnel and choose which Conversion Leads event you want to optimize for. 


If you did this correctly, in Meta’s Events Manager, your Pixel will show up.


By going into Settings, you should see three blue checkmarks proving that the Sales Funnel was set up correctly.
