User persona is very helpful to understand user behavior & interest of our target audience which helps us market better. The tool has helped me learn more about my visitors as I used it extensively over three weeks during one month last year (my first experience with Personalization). It was not easy at all but worth trying out if any such tools are available from within LinkedIn itself because that's how we've got this particular piece right now! We're able to build profiles using insights gained through Personification and test them against real users who come across these Profiles via Search Marketing or Sales Leads. And then decide accordingly whether there should be changes needed while designing content/CMS etc., so as to make their experiences even greater than they have been till date!! This also allows us <a deeper understanding of what kind(s)of people need specific information before buying something online - hence improving customer retention rate. A lot less efforts were.
