Hello @BrendaW965 ,
We can't capture a random landing page's visitors unless they either specifically submit contact info (such as with landing page sign up forms' reporting), the the click report of an email where you've linked your landing page, or in the purchases of a shoppable landing page.
If you're looking to use click segmentation for an email, you merely need to add that when you're inserting the landing page link into an email. Please keep in mind that click segmentation doesn't work for the webpage version of the emails, such as what you'd share on social media or in your site's email archive.
