General suggestions for Web Design Guidelines
There are a few helpful things you can do to evaluate the effectiveness of your web site: Ask people to look at your site and tell you what they think. Go through the experience of trying to buy something on your site, and ask friends and family to do the same. Note the ways the customer experience can be streamlined. Set target dates for improvements and stay on track. Test your site with different browsers, such as Internet Explorer, Safari and Firefox. Know your visitors and your target audience. Survey customers shortly after you launch so you can make improvements right away.
