I have content on my website, can I use that content for article directory submissions? or is it going to become a duplicate content?
It will be consider as duplicate content so try to spin your article and submit it to article article directories.
This is not a Good Practice because search engines will consider it as a Duplicate content and it affect your Search engine Rankings.
As per my thinking you can use content from your site for directory but spin the words first and do not use it for article.
for article submission, we have to use unique content, and that's effective for search engine ranking for your website
i agree with you we have to use unique content, and that's effective for search engine ranking for your website
If the submission is a duplicate article, I think there is not muchmeaning, it might be considered spam.
Duplicate content isn't the big issue that some people think it is. Google does not penalize websites for having duplicate content. But it will only rank one website with that content (the one it's algorithm deems most relevant). If you put out duplicate content to article directories, one of them might rank higher than your site. It's probably best to re-write your article for directory submission or syndication. You would be doing this for backlinks so you don't care if the re-written article ranks highly or not; don't do any SEO on the re-written article.
Don't copy it from your website. You can paraphrase it, change some sentences and then you can use it. Directly coping the content will spam your website.
