Over the years I found myself always going back through my clients sites and making small minor improvements. Even if we were not paid to do regular maintenance on the sites and just did random updates when the client requested I would often go in free of charge and make minor improvements. Many times they are only things that probably I would notice. But those things over time help keep the site fresh and little improvements add up. The changes would be small graphical improvements, adding favicon logos, iphone bookmark logos, google analytics or improvements with cleaner code.

Clients would greatly appreciate this attention to detail which has enabled us to slowly grow our base of close clients. Often times a small improvement or doing that little extra thing is all it takes to set you apart.
