We already know what makes a person attractive: symmetry and (apparently) a resemblance to our parents. The latter is disturbing beyond words.
But what makes a website attractive?
Probably not symmetry, and certainly nothing to do with our parents.
Colour? Use of space? Eye-catching graphics? Clarity? A picture of a grinning model wearing a headset?

The real question, however, is whether it matters.
Bafflingly, a large number of companies prioritise the appearance of their website over how well it functions.
Question: When did wowing your visitors become more important than engaging with them?
From a marketing perspective, the answer to what makes a website attractive is how well it performs.
