There are so many guides online. You just have to read them. Some guides you'll find on Youtube. Google is your friend. 

But be advised, most of the advice come from people who started blogging back in 2005-2010. What applied back then does not apply now, especially guest blogging since most bloggers regurgitate and rewrite somebody else's content who probably would have done the same. So practice caution in falling deep in that rabbit hole.
