I was actually watching some videos the other day on Duplicate Content. A lot of which I had thought was the case before watching.
Too many webmasters and new/inexperienced SEO's freak out at those 2 words, being scared of penalties.
It's not always the case as some are scared of using the same 3-4 words on one page vs. another. Some people do take their so-called understanding of things in a strange/paranoid direction.
Some people actually think using the same words across a website on many different cases is duplicate penalty. I got involved in a conversation a few days ago and told someone that they are crazy, unless of course they are trying to load their site with repetitive keywords. I said as long as your posts are worded properly and you aren't trying to cram the same keywords across your site and you are genuinely using the words properly, then you will be fine.
That's what triggered my Matt Cutts parody videos that I posted a couple of days ago.
I love those!!! I posted one on another site long ago and someone thought they were real! LMAO
Google won't show both in normal searches, the only way I saw that they preferred the https on 2 equal pages was to do an unfiltered site search - site:domainname.tld&filter=0 . That returns all the indexed pages including ones they don't normally show because they're too "similar."
Wow, thanks. I have learned something new today. Now I have to go and try that one out. :D
In a "normal" search they'll pick one copy to show you. In that example, they were showing https for the home page and http for most other pages. PS - they had a lame shared SSL certificate that returned warnings because info didn't match the domain - https wasn't intentional and it certainly didn't inspire trust in this case!
So you are telling me that HTTPS doesn't inspire trust? I guess all those Chinese sites selling traffic to unknowing people using the HTTPS protocol for their websites are trying to instill false trust? Say it isn't so!
Why yes I am

Google claims they can make sense out of duplicate content. They do ... sort of ... In real life, it confuses them and they just throw up their hands and don't treat any of it well. Also, both scenarios split your link equity.[/QUOTE]
