Domain & Hosting.
Sizes, they matter a lot. They matter even in our daily lives wearing tight/loose clothes has never been a pleasure to anyone. The same thing goes for websites and blogs. If you are on your way to creating a blog which is about a niche that requires heavy imagery, rich media (Videos, GIFs, animations etc.) then you would require a hosting that provides a big volume of storage and bandwidth and if your niche is a bit dry and just needs text, then you’re good to go with Signin.
The first step, to begin with, is to identify the needs of your website. If you have an eye for the future growth of your blog as well then you might need a more expensive hosting.
