I've been told that submitting to many sites can be dangerous. The dupe content filters can end up hurting your rankings. Is this true? I've also been told that many article sites were recently penalized and lost some of their PR. What is the ULTIMATE move for submissions? I want to submit about 20 articles on one topic. What sites should I submit it to?
No the dupe filter will just prevent them from showing up in the serps. But the pages still exist and don't harm your site. There were a few sites that got spanked but it seems like they bounced back. The reason we do articles is in hopes that others will pick it up and put it on their site and get a juicy think back from that site not from the article site. You still get juice from the article site but not as much as the site that copys the content. Thats why it is important that you write good articles.
Always remember there is big different between quality and quantity and I'm always go with quality. Hope you got your answer ???
only use quality article sites where only good articles are published try not to use sites where most the articles are just promotional
