It's true. We've been acquiring leads for some of our clients at cheap at $1. It use to be more expensive before but I guess because of the IOS changes Facebook has been working on optimizing their platform better to support lead forms.
I think it is a good opportunity to focus on your creative lead form ad and also leverage the platform.
Just keep in mind because they are signing up on the form you need to have a solid backend system in place and don't let your hard earned spent money on leads fall through the cracks.
I created a quick video that shows you how to create a zap so that when leads sign up you can input them into a system to send the lead automated email and text reminders.
