You have probably spent quite a bit of money building your website. You probably also wish for your website to be a source of new business for you and you may have marketing and SEO strategies in place. If you are a UK business a UK web hosting company should be part of your marketing strategy.
UK hosting will not only make your website load faster to UK customers but also increase your search engine rankings within the UK search engines. This is because most search engines, such as Google, adapt their search results to reflect the country that the searcher is in.
If you choose to use a cheap American web host, your page ranking for the UK may suffer.
