To collect the data you need to qualify your leads, you can use a combination of methods such as web analytics, lead magnets, lead forms, lead nurturing, and lead qualification. Web analytics tools like Google Analytics, HubSpot, or Leadfeeder can track and measure how your leads interact with your website, landing pages, and content. Lead magnets like ebooks, case studies, or webinars can be offered in exchange for contact information and some basic details about the company. Lead forms on your website or landing pages can be created with tools like Typeform, SurveyMonkey, or Formstack to capture budget, authority, need, and timing. Lead nurturing through email, phone, or social media can be done with Mailchimp, ActiveCampaign, or Hootsuite to send personalized messages that build trust. Lead qualification can be done with Calendly, Zoom, or Drift to schedule meetings or demos and tools like Gong, Chorus, or Salesloft to record and analyze conversations to identify pain points and buying signals.
