...because the right brain sees a webpage as a picture.
The visitor will, almost instantly, judge your site as 'good' or 'bad'.
Once someone has made a judgment, they tend to defend their position.
This is why website design is so important (it's tough to change a first impression).
If you would like to talk to me about your website, just ask. There are lots of things you can do to make a website more effective, without major changes.
All the best,
