Duplicate Content Penalty
This may not be a penalty in the formal sense of a penalty being consciously imposed for some infraction, but it sure looks that way.
Duplicate content is when the same article is posted on more than one website.
You would think that the Google search engine is “smart enough” to know what site has the earlier date stamp and should consider that copy to be the original, and all subsequent copies to be copies.
For some reason it doesn’t work that way
When you post the same article on two websites, the website that has the highest authority ranks higher.
For every website this hurts, and for website that have a lot of traffic this can hurt A LOT.
The trigger for this was a Google update named Panda.
The cause of this was duplicate content.
A Little Technical Mumbo Jumbo: rel=canonical
If the other websites flag the post using the HTML tag”rel=canonical”, the duplicate content is not indexed by Google and hence there is no duplicate content penalty, but can you know definitively if they do or don’t do this?
The easy way out of this dilemma is simply not to do it.
If you don’t want Google penalizing you for duplicate content, don’t publish any.
Does your business need greater visibility? More web traffic? More leads?
