how can i make a good blog?

You can start by obtaining a blog site from like blogger, wordpress, etc... then you will need to find something that interests you to write about, preferabally something you know about. then just start writing and posting! HAve a great day!!

Take a look at my blog, http://bloggerlisted.blogspot.com . I have made a few before and just started that one using what experience I had before. Check it out for examples. Also, keep posts short and to the point. People read through a lot of blogs daily and don't have time to read a book. Inform the readers as much as possible in as few words as possible. Good luck!

just go to a site like blogger, choose a topic to write and start writing, at the beginning you can visit other blogs just to get the hang of it
