Wanted to ask. Say I write a page on my website about say " mobile phones" and then I go to ezinarticles and add the contents on that page as an article and link it to the page on my website. Will this be a good backlink or will it be regarded as a bad link-duplicate content. thank
Submitting article in ezinearticles with a link in to it is not bad. IMHO it is very much needed to promote your site.
if u use same article on both it is not good and ezinearticles doesn't allow duplicate content to be posted.
The thing you can do it is, first post the article on Ezine and including a link to your site. You will get Quality Backlinks with it.
That's not exactly true. Ezine does not let you post content that is already posted on Ezine articles, but they will accept content that is published elsewhere on the web IF both the article you are submitting and the preexisting content are attributed to the same pen name.
