Many people seem to be very excited on "Landing Page services": What is the Best Landing Page Service? (Performable vs. HubSpot vs. Unbounce vs. ??)
I have already my webapp which does have a landing page (the first page). Now it seems to me people think on needs to use one of these tools. Do I use them besides my app or before the app launches? What are your strategies?
Unbounceable even speaks from a concrete number of visitors on my landing page. This confuses me. Were do the users come from? Why is this landing page better than mine?
