Do not trust!!!!!
Do not trust!!!!!! Didn't speed my up website, actually was left slower and did not get my money refunded. Only got my YSlow score to a D. Waste of $49! If you are looking to speed up your website use 'WP Speed Guru' he is GTMetrix approved and recommended, and gives you ongoing support throughout. Alexei Kutsko (Speed Guru) helped me get my website from 9 seconds to 1.1 seconds. Please save your money and time and do not use ZippiSite
