Final answer:
The marketer should use Tokens to personalize the landing page. Filters, Social Button, and a link to the homepage are not directly related to personalization.
Step-by-step explanation:
The marketer should use Tokens to personalize the landing page. Tokens are placeholders that can be dynamically replaced with personalized information, such as the user's name or location, to create a more tailored experience. For example, if the marketer wants to greet the user by name, they can use a token like {{name}} and the landing page will replace it with the user's actual name.
Using Filters may help the marketer segment the audience and show different content based on specific criteria, but it may not provide a personalized experience for each individual visitor.
The Social Button and a link to the homepage are not directly related to personalizing the landing page.
