Did you know that you can register your business domain for more than the standard 1 or 2 year duration that is usually the default setting?
It might cost you a hundred quid or so to extend the registration of your domain for 10 years, but it is well worth is as it shows Google that you are serious about your business and your brand, and gives Google faith in your website, resulting in potentially better organic search positions.
Obviously, this does not take away the fact that your website will still need to be a great source of written content, or that it will need to be well linked to by social network users etc, but it is another easy to achieve tick in the Google box.
