What is the benefit of buying a domain name for my giveaway funnel?

Kendall Kuehnert asked us, “Quick Question:
What is the benefit of buying a domain name for my giveaway funnel?
Thanks for the responses ahead of time!”

“We recommend buying a domain so that you can set up your domain with Facebook and track how many people register for your Giveaway campaign.
Without a domain/pixel set up, you’re making Facebook “blind” and removing their ability to help you improve the performance of your campaign using their algorithmic targeting of your audience.”
