Another thing to consider before completing your purchase is the selection of your domain name. As we will discuss in later sections, apart from web hosting, we need a domain name so that people can remember our website. Servers and, as a result, websites have an IP Address. This means that the facebook.com website has an IP address, such as 157.240.9.35. Imagine if there was no facebook.com and all users had to type 157.240.9.35 every single time they wanted to use the website. There is no way that the internet could have such dimensions as it has today using this kind of interaction with servers and requesting websites. To conclude, this is the reason that we came up with domain names; each website has a domain name that obviously is easier to remember since it consists of letters. Picking your domain name may be straightforward, but there are some things that you should consider before paying for it. As we said, a domain name is something similar to facebook.com, linkedin.com, vasilistzivaras.gr, or anything that makes your website unique in the world. There is no domain name that corresponds to two websites. First of all, it is important to know that a domain name is quite important for Search Engine Optimization (SEO). SEO means that the name of the website is a variable in the Google search algorithm. If we do not want to make it available to the internet and we need the website for personal use, that is OK and you probably do not have to buy a domain name, as I think that you can remember an IP address. However, if you are creating a website to be made available to the entire internet and adding it to Google's search engine result list, then the URL or the domain name should be something that really represents your website; for example, it is stupid to have a website about clothes with the domain name catsanddogs.com. At this point, I should say that many hosting providers give you free hosting for a small website when buying a domain name. This is how I, personally, have developed my website vasilistzivaras.gr.
