I heard about Premise during my research, but only quickly glancing over the service after seeing that it's a Wordpress plugin.

Thinking about it now. It doesn't really matter if it's a plugin since I can just install Wordpress in a subfolder.

Does the URL matter for a landing page? For example, if I have product A's URL as widgets.com/products/a. Would it be fine to have the URL of the landing page for this product to be: widgets.com/landingpage/a. In this case, I would've installed Wordpress+Premise in /landingpage.
