Duplicate Content | SEO
Duplicate content is an issue that is often brought up on internet marketing and search engine optimization forums. Oddly enough, I see numerous SEO "experts" horrible information every day. I haven't figured out whether they do it on purpose or if they actually believe it, but here is the truth about duplicate content.
Duplicate content only exists within a single domain. If you write and article and post it on your website, then post it on your website again, you'll find yourself in trouble for duplicate content. There are 2 solutions to this. First, don't post the same thing twice on your website, there really is no reason for it. Or second, use rel="canonical" tags if you have some reason you really want to post something twice.
But where all of the misinformation comes in to play is article submission. So you write an amazing article and post it on your website, but you want to submit it to some article directories as well. Many SEO "experts" will tell you that you have to purchase a program to spin the article or rewrite it by hand or you'll find yourself in trouble for duplicate content. This couldn't be further from the truth.
You see, having your article reposted around the internet is called syndication. In theory, syndication shows popularity. If a news website posts an interesting story, bloggers and other websites are likely to copy the story, post it on their websites, and link back to the original source. Now Google couldn't sit around and let people copy and paste their way to destroying competition, could they? Nope, and that also makes me wonder why so many people are petrified of posting their articles to article directories.
Now keep in mind, Google does have a sort of "duplicate content" filter within its searches. It will only allow an article to show up on search results so many times before other copies of the article are filtered out to make room for something that may be more relevant to what the user is searching for. But that doesn't mean those articles are not indexed, they just simply don't show up for some searches. They may however show up for different keyword searches.
Hopefully this puts your mind at ease and has enlightened you. You can now feel comfortable submitting the same article to multiple article directories.
