The prospect of generating leads without landing pages is tempting to many businesses, regardless of industry or size. Think about it: you can get a new lead campaign up and running quickly and efficiently, saving time and money on landing page development costs and pricey ad campaigns to drive website traffic. Opt-in lead ads allow you to target potential customers on the sites they already visit. There, they’ll be able to interact with the ad unit and provide all the contact information you need to add them to your database and start nurturing those leads into customers.
