Your website has to contain interesting information: good quality pictures and text that actually means something.
Most websites say something like "Welcome to our website....blah, blah, please buy something..."
There are hundreds of thousands of companies in the UK with websites. Why should a potential customer choose your company to place an order?
Google has a phrase for this: "expert content". Google's algorithms can accurately read words. If the automated systems decide your website is interesting it will boost your position in the search listings.
It is important not to simply make general statements. Quality content is the key to impressing potential customers and making Google work for you.
