There are million of people surfing the Internet daily, and most business owners don’t properly optimize their marketing efforts to try to convert them into customers. The easiest way to drive online traffic is to buy your own personalized domain name; a personalized domain allows business owners to create their own niche space on the Internet. 
When you buy a domain for your business, it helps sales and profitability in the following ways:
Credibility
Tech savvy customers expect to be able to find companies online. If you don’t have your own domain name, you don’t give people a chance to check your website out before they use your services. A cheap website makes your business look bad, and most people who can’t find your website won’t even give your business a try. When you choose to buy your own domain, you add credibility to your business; you look sleek, modern and professional. It shows that you are a serious businessperson.
Mobility
If you set a website up on a domain that you don’t own, then you get stuck with that registrar forever. Free websites aren’t mobile, so business owners can’t transfer them in the future. This hurts businesses that outgrow their old sites; when they need to transfer their websites, they have to pay someone to completely redesign them. Buying your own domain lets you switch registrars when you want. You own everything on your site, so you don’t have to worry about the legal ramifications of moving your site to a different company. When you own your own domain, switching hosting companies is as easy as redirecting your domain name.
Avoid A Loss Of Momentum
It can cost a lot of money to promote a website when it first goes live, but eventually, your promotional efforts start to build momentum. When this happens, the price of your marketing goes down; when your efforts build up, you have to pay less to maintain them. It gets to the point where you attract traffic to your website at a very low price per person.
When you own your own domain name, you never have to worry about your host closing up shop. With free domain names, you don’t own your site, so the person that hosts it can simply shut down their service. If this happens, you lose all the marketing efforts that you put into your site. You have to start over from scratch, and that can get very expensive.
