Blog posts should be short.
Writing just a few lines is fine.
Post frequently. Every few days would be ideal, although some bloggers post daily.
WordPress sends a digest of posts from all blogs you follow on Monday mornings, so make sure you post each week before Sunday night.
All posts on your blog should be about the same topic.
Don’t write one post about gaming, then one about football and another one on how your
computer doesn’t work.
If you’re interested in different subjects, create a separate blog for each one.
Include an image in every post. It must be copyright-free and attributed – obviously.
