Some small businesses such as cleaning companies offer a diverse range of cleaning services. I have clients who have more than one website to promote the services they provide. This usually works better for them than having all their different services listed on one site.
Here's a couple of new websites that I have recently completed that are designed with a 'responsive' layout, are quick to set up, and offer great value for money.
Both clients have 3 websites each promoting different services in their area.
