I create 2 to 3 articles per day... I post all articles to my wordpress blog same time i.e within 15 minutes.. It create any problem for Google SE. My google traffic reduced 1000 to 50 per day...
Nop!! Their would be no penalty for your website or blog either , if you give the link of the site or page where that article was previously was uploaded as a Courtesy.
Please elaborate the question a little bit, you make 3 or more articles per day and post all the articles to same blog or different blogs..???
I think there are other factors involved. Posting content, even duplicate content, is not such a serious problem.
Nope.. there isn't any penalty for that as long as the articles are 100% unique. But I'd suggest you to to wait for the previous article gets indexed before you post another.
