What's best practice for blog meta titles?

[Lubeman]

I have the option of placing meta titles on the actual blog, or on the blog  category on my site. Should I have separate meta titles for each blog or bundle them under a category and try to drive traffic to the category? Can anyone help with best practice?

Every page/post on your website should have a unique title tag. Title tags of a specific post should relate to the post's header tags and content and should target long-tailed keywords. It is great way to get ranked for a large variety of search terms.

Category title tags should also be unique, but they might not be as important because people typically want to read and link to an individual post.
