I write unique content for my blog and i wish to promote my blog through article submission.Is it fine if i write and article and post it on my blog as well as Ezine Articles. Or i have to write an altogether different article for Ezine. Please suggest.
If you duplicate content is not an issue for you then you can, but remember to give credit to original authors.
Don't do that most probably you article will reject. Write fresh article and submit it you can get lot of advantage. If your article approve(copy paste one) in ezine article your blog goes down and ezine article goes up in google searching.....
there is no problem in posting same content on ezine. as there is already too many text on every page so it is not 100% duplicate.
I think Don't do that buddy, I ever did that kind of thing, and google give more value to the article posted on ezinearticles rather than my blog/site
And what happens when the article at the blog is indexed first and after that added to ezine - is that bad to for the original blog? Should we do that? There is a chance that the content from ezine would taken for a duplicate rather than the text from the website?
No man you cant do this, You have to write another fresh article for ezine if you really want to get good back links, Also it useful for your website.
