The goal of the landing page is obviously to get them to click the order button and place an order. The first area they see (above the fold) should include quick facts, eye catching photo (attractive woman smiling), short headline, and the order button.
A border for a video on the left side would be good. Smaller than the standard youtube video size I suppose.
Order buttons should be big and really jump off the page to stand out.
There's a few additional goals, which include giving the visitor a sense of security and trustworthiness, along with the desire to lose weight and get in shape.
The content will include;
Clinical tests on African Mango
