Your website address should be...
It is possible to put your full company name, location and full list of services in a web address if you wish. No-one will be able to remember it however, and even typing it in from a printed reference will be difficult and time consuming.
If you can, avoid using hyphens in your web address (try saying out loud a web address which includes a couple of hyphens - it sounds awkward and isn't easy to remember).
For instance, www.shedsandspanners.co.uk is no good if you stop selling sheds, just as www.drsjonesblackandwinter.co.uk is no use once Dr Winter moves to another practice and is replaced by Dr Brown.
If you have a very long company name you may wish to consider using a shortened version.
