Your blog is dead for whatever reason and you need ideas to revive it.  Dead blogs are actually a common occurrence on the internet for a number of reasons.  Some characteristics of a dead blog are as follows:
1. Rarely updated.
2. Minimal Google traffic
3. Plenty of broken pictures and links

Some of the main reasons that dead blog occurs are as follows:
1. Lack of interest by the author.
2. Google has taken the blog out of their index
3. Blog topic too hard to create new information.

Take a blog like Nintendo Gamecube Game  blog.  For a topic like this, it is doomed from the start to become defunct at least at some point. Any blog that has a topic with an ending time line is going to have a problem sooner or later.

What To Do With a Dead Blog
Dead blogs might be dead, but it doesn’t mean you can’t use the information for another newer blog.  Some blogs which have been deindexed by Google I’ve often had to just build an entirely new blog, use the same information, as well as add more.
