How to choose an AI lead generation tool

Start with where your leads come from. Inbound leads arrive through your site and ads, so you need pages and forms. Outbound leads come from prospecting, so you need contact data and outreach. Most tools here have a free plan or a trial, so test one before you pay.

• You want visitors from your site and ads to become leads

  HubSpot gives you free forms, landing pages and live chat, and every lead lands in its free CRM. Starter removes HubSpot branding for $20 per seat a month. For ad campaigns, Unbounce tests page versions from its Experiment plan and routes visitors with AI on Optimize, and Instapage suits teams building many campaign pages, from $79 a month billed yearly. For more traffic on a small budget, Landingi starts at $24 a month with 2,000 visits, and Leadpages at $23 with no traffic caps, both billed yearly. Our landing page builders guide compares the four. If many of your leads phone you, CallRail shows which ads, keywords and pages made the phone ring, from $50 a month billed yearly plus usage.

• You sell to businesses and need contact data

Cognism suits teams selling into Europe, with phone-verified mobile numbers and Do Not Call screening in 16 countries.
