Should I buy multiple domain names?
This is something we get asked a lot.
Our view is that you should have one main domain name for your website. Buying multiple domains and pointing them at your website will not give you any advantage from an SEO point of view and may cause brand confusion with your clients if you advertise different names.
You should never run your website on more than one domain name as this will cause serious duplicate content issues with search engines and could seriously impact your ability to be found.
If you do own more than one domain you should also redirect or forward these onto your primary domain.
