BLOG or WEBSITE / Domain name
If you use a blog for business, it is better to be under your own domain like this WP based blog of mine (my first name plus my nationality). E.g. Blogger can delete your blog, if there is too much business promoting.
If you do not have already an own domain name, buy it as soon as possible. Try to choose a domain name, which tells something about you.
If you have some difficulties in English, use Reverso to check your text.
