With the most commonly used method, folders, we create a separate folder for each of our categories on our server and direct our pages to this folder. In addition to being a very simple, very common and very reliable method, it is especially suitable for small-sized sites and is the most suitable method for ensuring the authority of your domain name. When we compare it to the other methods mentioned, this method is the easiest. Subdomain is a completely new domain. It does not benefit from the authority of the main site. SEO work must be done from scratch. The folder benefits from the authority of the main site. Our recommendation is to use a subdomain when a completely different job will be done on a domain name. We recommend using a folder in other cases. Our company, which has the best place in the sector with its experience in professional web design, prepares websites that suit your requests and needs in this regard.
