When using avatars to solicit leads, create plausible buyer personas with relevant backgrounds and interests; and then revisit them frequently thereafter (every quarter at a minimum) so as to ensure your message stays fresh and relevant to your target audience. It is vital that you maintain insight into who your typical customer is and what they might be looking for.
Lead nurturing is as crucial as the initial enticement; as RETAINING leads is as important as LURING them. After all, one can snag a billion leads; but that means nothing if one loses them between the initial hook and the final conversion.
