The Next Step: From Automated Leads to Qualified Opportunities
Lead automation is the initial and most important step. These tools can assist you in bringing in and capturing enormous numbers of leads effectively. But a full pipeline is worthless unless it's full of high-quality leads. The actual task is to make those raw leads into opportunity-ready leads.
That's where AI takes over from old-school automation. Although the above tools are great for the "how" and "what" of lead gen, AI delivers the "why" and "when." It's a smart layer on top of your current tools, examining the quality of your leads, forecasting their chance of conversion, and advising your sales reps on the best action. Moreover, businesses employing AI for lead generation have averaged 25% higher conversion rates.
