By registering multiple domains, you protect your brand online by safeguarding your domain name. Just because you’ve reserved one domain extension, it doesn’t mean that all of them will automatically be reserved for you. Domains are registered on a first come, first serve basis so if someone else gets there first, they could snap up your name. Cybersquatters are especially likely to do this – they buy a domain they don’t even want just so they can sell it to the ‘rightful’ owner at a higher price. If you register as many domains as possible such as businessname.co.uk, businessname.com, businessname.net, etc. you protect your brand and make it a lot harder for cybersquatters or anyone else trying to harm your brand. Try to capture all possible variants that might be typed in during a search — including misspellings. With multiple domains, you have to watch out for duplicate content as Google could penalize you for this. You don’t necessarily have to write brand new content for each domain (unless you want to), simply use a 301 permanent redirect to solve the problem.
