Just when you think you’ve made something idiot proof, someone goes
and builds a better idiot. We know your visitors aren’t idiots, but if
you make your site so a 5 year old can use it then your visitors will
be able to do so without even thinking about it.

You already know how to use your site, so do the people who built it,
but what about your visitors?Small stumbling blocks in the journey
through your site can cost you a fortune in missed opportunities and
you and your designers may not be able to see the wood for the trees.

Usability testing should be done early, before you launch and
certainly before you start spending money promoting it. Usability
studies needn’t be expensive, they’re no longer the preserve of the
big boys, getting real life people who weren’t involved in building
your site to test it for you is the best money you will ever spend.
