After how much time after publishing my articles on hub pages, I can republish them on other sites?

Never. Hubpages wants content to be exclusive to this site. You will have to unpublish here before posting somewhere else.

You aren't meant to publish them on both hubpages and another site at the same time. If you want to put them on your other sites instead, you can unpublish them from hubpages and then do it.

You can't. Not at all. Of course, you CAN republish it but it will just be duplicate content which both HP and search engines doesn't love it.So, yup, totally not advisable.

AjmersinghjiYou are not supposed to republish your hub articles in other pages. You can rewrite but not duplicate.

I think publishing same content more than once in different places will be treated as copied content.

You can publish your hub and then publish the same hub in your blog or web site. But then what happens? They will be recognized as duplicate content by google.

If you are publishing them in an another web site like hubpages, your article will be recognized as duplicate and the particular article will not be published. Google Search engine ranking of your web site/blog will be dropped quickly due to duplicate content. Yes, I know, you are the author of the particular article, but this is the scenario.

Therefore DON'T DO IT.

Correct me if I am wrongBut like what the others are saying it won't be good for your hubs or the page where the text is republished.

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.
