Research: Use blogs that publishes content that is based on research ans is relevant to what your topic is.
Remember that content is the key to a successful blog. Quality scores over quantity in getting audience to your blog.
Avoid using SMS abbreviations in blog post and at least run the post through a spell-check in MS-Word before publishing. If the bloggers cannot take the time out to write proper English, why would the readers bother reading through that cryptic puzzle?
