If you have or buy a domain and want to sell it. What is ment by the term "domain development" E.g: I would say mid $xxx but without development $0 What does the above mean? What is it I have to do too develop a domain?
What they are referring to is the development of a website on the domain. If you own a domain name and there is no theme or content (you just simply own the domain), then it is considered an undeveloped domain. However, if you build a website on your domain, then you have a "developed" site (or domain). The statement that you gave as an example means that that person appraised the domain of having a value of $0. Therefore, your domain has no value to a reseller or an end-user (in that person's opinion, it is worthless). Though, if you were to build a site on that domain (developing it), then it would then have a value of $100+ To develop a domain, you would have to open a hosting account and then upload a theme and content to create a site. Then you would change your domain's nameservers to point toward your hosting. By bringing these two things together, you will have a developed website.
