Your web site is the way many of your customers first get to know what you offer and how it will benefit them. Ideally, that site comes up on the first page of a search engine (SEO, we are looking at you!), but the experience a first-time visitor has on your home page will determine whether or not they come back.
How is your message displayed and delivered? Today’s multi-device using customers are using laptops, phones, and more, to read email, surf the net, and view ads. A clear technological understanding of how that works and what won’t work should define how your message is put out there. For instance, a dancing bunny with wiggly balloons to click on is actually difficult to program successfully because a lot more information is needed and more can go wrong. That same bunny sitting still might be better for your purposes.
Is your web site easy to figure out on different devices? Since there will be users with varying speeds and bandwidths, simple is better than flashy. A good search engine is essential. The home page should have the most commonly sought information right there, easy to see. Tabs or links for further information should also be easy to see and should work when clicked on. Get feedback from your customer base and use it to improve their experience on your site no matter how they visit.
Are you using your data dynamically? There’s more to metrics than click rates. If you aren’t analyzing the right data for the right information, you are simply learning how to play with software and numbers. Know what makes a result statistically significant and numbers start to mean something real. Today we have access to an overwhelming amount of unique data that can improve specific business practices, but it has to be handled correctly.
You could try to figure all this out by yourself, or you could delegate the bulk of it to professionals who already are doing successful web design for others.
