If your website is going to store personal user information, make sure that your web design incorporates proper security practices. As an obvious example, do not store user passwords in a plain-text file that is accessible through the browser. You should instead store them in an encrypted database, and utilize proper access restrictions. Ensuring the privacy and security of your users will help build trust in your website.
Try including real customer testimonials. Very few want to be the first to try a product or service, so let customers know that others have tried your wares and that they were pleased with them. Try asking some clients that have done projects with you to create a short paragraph about their experience with your company, to put on your site.
To help your website function the way it is intended to, make sure all your links are working. If you have broken links then your visitors may get frustrated when they try to click on something that interests them. Frustrated visitors is not something you want because they end up leaving your site mad.
When establishing yourself as a web designer you need to have a good list of references. After you have done work for someone you need to take the time to ask them about their experience and if you have their permission to use them as a reference for future clients. Most people will not mind if you have done good work for them.
So you should now have a better grasp of how you can design websites and make a good profit off of them. Be sure you apply all that you learned today and always seek out new information so that you can be successful with your web design goals in the future.
