Final answer:
A PURL is a dynamic landing page that is personalized based on the URL. It allows marketers to create a tailored experience for each visitor.
Step-by-step explanation:
A PURL, or Personalized URL, is a dynamic landing page that is personalized based on the URL. It is commonly used in marketing campaigns to create a tailored experience for each visitor. PURLs allow marketers to greet customers by their name, show personalized content, and track individual engagement.
For example, if a company is running a promotional campaign and wants to address each customer by their first name, they can create a unique URL for each customer like 'www.company.com/john_doe'. When John Doe visits this link, the landing page will be personalized to greet him as 'Welcome, John Doe!' This customization is possible because the URL contains the necessary information.
In contrast, option B is incorrect because a PURL can redirect to another page based on the visitor's interaction. Option C is also incorrect because although tokens can be used to personalize a PURL, it's not a defining characteristic. Lastly, option D is unrelated to PURLs as CNAME refers to the DNS settings for a domain.
