In my opinion, duplicate content is a waste of time and bandwidth.
I have duplicate content all over the place. All ranks, all brings in traffic. #
I'm not just talking about a little bit, I'm talking perhaps 2000+ identical articles.
Never had a problem (they were all original once, all written by me, all show me as the author) Never been sandboxed. Only Ezine have ever moaned, and that has been only about 5x in almost 2100 article submissions (over 12 million hits and a CTR of 8.4% in two years and 4 months)
Sure, worry about duplicate if you like. I never have, and until I feel the wrath of this mythical "duplicate content" slap, I won't.
One proviso. All my own web pages are unique, it's my submissions for links that are all duplicated.
Link fodder content? Nah, never suffered.
For one keyword i'm second, fourth and ninth on page one of google for exactly the same content (word for word exact) submitted to three different places. Where's the duplicate content slap for that?
- Original content (i.e it all belong to me) YUP
- Relevant content (i.e it pertains to the niche/blog or forum it's posted on) YUP
- Optimised content (i.e for the reader it is correct grammar, and for me it has keyword optimization, header tags and good alroad SEO) YUP
- Rewritten ...Nah - can't be arsed.
