One of the downsides to a blog is the ability to easily assign meta keywords and descriptions to each blog post. I have done some research and found with a simple and fantastic plugin called HeadSpace 2.
HeadSpace 2 has two different ways of creating meta descriptions and keywords.
1) For those of us who feel we don’t have enough time, there is the automatic way. HeadSpace 2 can put an excerpt of your post in the description tag and the categories associated with the post in the keywords tag.
2) For those of us who need control, there is the manual way. Once installed each post now comes with a meta description and meta keyword box on the posting screen. Simply fill those two out and HeadSpace 2 will do the rest.
