Apart from the mistake that can happen prior to domain registration (typo or wrong spelling in domain name), there are number of mistakes that are possible after domain signup. I will explain the most common ones in this piece.
Hiding Domain Name Identity: Online website not only allows good internet marketing to your business but it also makes it open to competition or unwanted advertising aka spam. Leaving your identity information means anyone with an internet can access whois information of your domain name and grab domain owner’s identify information such as email, phone number. This information can be used by spammers or competitors. It is best to use Private Registration to hide your online identity associated with domain name.
Email Signup Confusion: Most online business owners make this mistake, as soon as they register their website, they want to start using their email associated with newly signed up domain. They try to use the email at domain registrar and later find out they need to pay separately for the email usage, which they could use free of charge at their web server. It is best to analyse and decide whether you need a dedicated email service or you can use the shared space at your website for email management. Offcourse they can use go-daddy web hosting and use the email at that area. If it is business email and your business could be at stake due to loss of emails or accessibility errors, then dedicated email service should be first choice otherwise stick to your shared email at your web hosting space.
Domain and Server Linkage: Especially for web technology non-savvy users which unfortunately are in majority does not understand how their website works. As soon as they signup for their web name, they start getting confused on why their website is not working with new domain. Their is a technical step involved which is the most important for getting your website in a working condition. This is to connect your website in most cases located in a remote server (could be anywhere in the world) with your domain name registered at godaddy located in US. This is done by entering web server nameserver information under DNS section of domain control panel. DNS stands for domain name servers.
Nameservers: A nameserver is IP address of web server where you host your website. There are normally two nameservers needed for a successful linkage of domain and server; these are called as NS1 and NS2, Nameserver 1 and Nameserver 2 respectively. You will need to ask your current web hosting provider for your website nameserver information.
Domain Propagation: Patience my friend, this is the number one mistake that website owners and developers make around the globe and repeatedly. As soon as you leave a linkage request between your domain and the web server, you get frustrated within few hours as you see it unable to function. One should understand since the internet and web-space is expanding resulting in larger number of web servers worldwide, it takes time to inform the internet (major ISP/ networks) about the new change. This normally takes between 24-48 hours, so once you link nameservers with domain, give it two days to establish the understanding with internet about your new domain and web-server marriage.
