Every time I add my a new post to my blog on my website, it posts the same blog post to wordpress, blogger, tumblr and diigo. I was wondering if this is bad for seo considering duplicate content. I do this to make sure i get lots of exposure to my blog and a bit of manual link building.
I ran the google rich snippets tool on my blogger blog and it says that the author is unverified, but it does have my google plus profile url next to the unverified box. Is this because it sees it as duplicate content becuase it has picked the content up on my website blog?
Thanks in advance if anyone can help.
