Do you publish the same articles on different sites?

No probs. idont see any issues as it is for different sites...same site u may not repeat but for different sites same matter is not an issue from my opinion..

Several times I will publish the same article on several sites, but with minor differences. When I do news articles, I'll usually start with Associated Content, though they don't pay for upfront for news (unless they have a call for the item), they seem to do a good job of getting articles to pop up in search engines so others can find them. If it's an opinion type of piece meant for debate, I'll usually go to Helium first and then submit to Associated Content. I always submit as non-exclusive to all sites as the way I see it, publishing to these sites is sort of like self-syndication.

i have done that in the past, but a lot of places dont like you doing that. they insist that it be original and not published anywhere on the net.

Well, I have published a few on a few different sites. If you think you can get upfront payment it is best to start with AC. If it is published on too reputable of a site they won't pay upfront for it. But make sure it is non-exclusive when you do it. If they except it you can then go to Triond, Helium, and your other sites from there on out. Triond sometimes doesn't except them if they find them on the net. So sometimes it is best to start there. I have done this a few times and increased my earnings with the sites I write with. I don't do it often though. Helium won't sell your article if it is published elsewhere because when they sell them they sell them co-exclusive. If Associated Content doesn't pay upfront, I always publish it elsewhere. Sometimes word for word and sometimes adapted to fit the market (such as Squidoo).
