If I write blogs about my hubs, from many free blog sites out there and add links to all of them?

If you link all of your blogs together in a circle that would be a link wheel, and if it's a closed wheel that could be considered as black hat seo so I wouldn't close the wheel. But you can only benefit from those blogs as.

3) no, they will probably not replace your hub, that is if your hub is full of quality content, make the blogs relevant and you have nothing to worry about!

4) using the same keywords will just make your hubs more important and relevant on the subject, so that is a must.

Sure! I am gonna use your idea. Thanks for a hint!

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
