Backlinks, communication, keywords, other SEO practices, all these things are important to a successful blog post. What I find MORE valuable, however, is one simple word: editing. If you're going to write a blog post in ANY language, it should be well-edited.

How much time do you spend editing, and perhaps even rewriting, your average blog post? I typically lean towards an hour-ish of writing with spurts of editing in-between, followed by one (sometimes two) final slog through the completed piece. I often check back later to see if I missed any typos or grammatical flubs, as well.
