Facebook page header advice

For all those running small, retail businesses through / with the help of a Facebook page, here is my advice: common users have no idea how to use "about" sections, follow links, prompts to actions such as the "contact box". They want all essential data LARGE, visible at all times, plain and simple. So my advice is to create a header image (828 x 315 pixels) containing the following elements: logo, website, contact email, contact phone and an image of the most successful / representative product. Here is what I did for my company and it works (at least there are less comments of the "how can I buy this?" type :) Atelierul de istorie produces and sells objects inspired by the Dacian, Roman and Celtic civilizations, but most customers are interested, for patriotic reasons, of the less known ancestors of the Romanians, the mysterious Dacians. Thus the best sold product is the Dacian hat and the logo is inspired by the ancient Draco, the mythical half wolf half dragon war standard of the Dacians.
