The landing page is for info. but as a capture page I am not sure what to write, it is not supposed to be as a blog or daily writings is it?

A capture pagei is similar to a landing pagei, except that it includes a subscription form for a mailing list. Typically, you would have only a single capture page for each campaigni. Normally, your blogs and/or articles would point to your capture page, and that is where your prospects enter their email address and subscribe to your mailing list.
