This presentation should help you improve your current desktop and mobile landing pages as well as how to develop new ones.

I wanted to make sure people could take the context from each of my slides so I made sure to add speakers notes to my keynote presentation. If you would like to download a version of the presentation with all the notes for each slide you can find it at: http://www.slideshare.net/BryanGroks/anatomy-of-a-high-converting-landing-page-34456053
