Leads campaigns can turn very costly as more and more companies are using it, but it is still effective, I know people in the real estate business having great success with leads campaigns. They paying around $30 for a qualified lead, which is nothing in this industry.
Eventually it is not important how much money you invest when you know your audience, only the ROAS counts.
Of course not every one have these big budgets, me either, that’s why I recommend chatbots, it’s a very smart way to collect leads and they’re very cheap compared to lead campaigns.
Give it a try
