copy our own article to other site

No. I don't copy any article from any where on the net. Because this is a plagiarism and prohibited and punishable under he law... If you plan to copy articles from different channel. Think twice friend, because it will give you headache after...

Even if it is not against a site's TOS you will do better to rewrite the article from a slightly different viewpoint. Not only will you avoid the duplicate content penalty, but you will pick up different long-tailed keywords. So if I were to write about cheesecakes, I'd write a basic recipe, then I'd write about the scientific aspects of making a cheesecake (ratios of cheese to eggs, baking methods etc.), sweet vs. savoury cheesecakes, and so on. I would post these articles on different sites and interlink them.

I can only respond with Triond as that is the only site I am on based on your list, although I think my response may apply to some other sites so checking the terms of service is always advisable. In Triond you can only post original content there first. After it is published there first, if another site allows it yes you can. But remember to always make sure that the site allows you to put an already published article as you will not want to be suspended. Me I have only posted original articles to one site at a time, I have not duplicated to any other site. I like to heavily market mines and like that my efforts are not for the same articles.

Read the Sites Terms of Service or Frequently Asked Questions. It will State if Cut & Pasting is Allowed. If it is Your Own Written Work. It should be Allowed as that isn't an Illegal Copyright. You may need to Submit a certain amount of Blogs or Articles to be Allowed to Use the Cut & Paste Function. Like Here at My Lot.

no i had never done this and i think its not allowed also ,why will this sites pay for your duplicate or copy paste stuff ,they want originality and if you are caught doing such things than they can delete your account forever.
