Few of the design elements can make a significant difference to the performance of a web page:

* The position and color of the primary call to action
* Position on the page of testimonials, if used
* Whether linked elements are in text or as images
* The amount of “white space” on a page, giving the content space to “breathe”
* The position and prominence of the main heading
* The number of columns used on the page
* The number of visual elements competing for attention
* The age, sex and appearance of someone in a photo
