Facebook Leads capturing refers to the process of collecting potential customers' information, such as name, email address, and phone number, through Facebook's advertising platform. This is typically done using Facebook Lead Ads, a specific type of ad format designed to make it easy for users to share their contact information with businesses.

When users click on a Lead Ad, they are presented with a pre-filled form containing their public profile information, such as name and email address. They can then submit this information to the advertiser with just a few taps, creating a frictionless experience that encourages more conversions.

Advertisers can use the captured leads for various purposes, such as growing their email list, remarketing to the same audience, or nurturing potential customers through a sales funnel. Facebook provides integration with various Customer Relationship Management (CRM) tools, allowing businesses to efficiently manage and utilize the leads collected.

Lead capturing on Facebook can be a valuable marketing tool for businesses looking to generate more sales, increase brand awareness, or grow their audience.
