Almost a year ago, I wrote about duplicate content issues with Magento. Since then, people have often been referring to Roy’s thread at Magento forums that quotes Google’s official blog.
This is what the quote says:
Having duplicate content can affect your site in a variety of ways; but unless you’ve been duplicating deliberately, it’s unlikely that one of those ways will be a penalty. This means that:
* You typically don’t need to submit a reconsideration request when you’re cleaning up innocently duplicated content.
* If you’re a webmaster of beginner-to-intermediate savviness, you probably don’t need to put too much energy into worrying about duplicate content, since most search engines have ways of handling it.
* You can help your fellow webmasters by not perpetuating the myth of duplicate content penalties! The remedies for duplicate content are entirely within your control. Here are some good places to start.
