The process of saving lead data to convert the lead into a paying customer is termed "lead capture." A newsletter subscription or a quote request form on a website is an example of a lead capture page or document. However more advanced web forms can collect much more information, such as firm size, industry, individual title, postal address, and so on, lead names, email addresses, and phone numbers are usually collected. Lead capture pages are crucial because they allow you to acquire essential information from your clients and nurture them further down your marketing funnel.
