What are the purchase behaviour of your customer avatar?
Take the example of a savvy investment-minded art collector. They make lots of research before purchasing and would like to know a lot of information and knowledge before investing. They would prefer to have personalised consultation and advice before purchasing.
How can we design this interaction to an online marketing channel?
1) Offer useful information that make them feel "smarter" in exchange for their contact information (this could take the form of an investment guide, questionnaire, etc.) This would also build their trust with a new brand.
2) Offer them a bespoke consultation where they could learn more about art as an investment
Usually this would take the form of a lead generation funnel - you drive an ad that prompts them to download the PDF guide in exchange for their information (E.g. email, phone number, etc.)
This is where your previous research on customer avatars comes in handy - what magazines do you customer avatar read, what hobbies do they have, what income class do they come from, which influencers do they follow, etc.?
