First of all, let me give you the meaning of blogger. According to google ,

a person who regularly writes material for a blog.
And what is a blog?

A blog is very similar to a website. I would say that a blog is a diary/journal that is (mostly) maintained by one person – blogger. Usually, blogs are being updated quite often (once a day, once a week, once a month). Blogs can be private, but most of them are available on the internet for others to see.

Kung ikaw ay may plano na mag blog o maging blogger,

Una, bumili at mag register ng domain name o website name mo

Pangalawa, kumuha ng magandang hosting package

Pangatlo, mag install ng WordPress para ikaw ay makagawa ng website para sa iyong blog.
