I think I understand, but can you confirm or correct me…

http://www.domain.com has three posts, and by default they are in order as the newest post first.

I then install WP sticky, choose my main sales/converting post, and allocate it to the home page (www.domain.com)

That then makes the post the only content on the home page, but also keeps it’s original permalink, so when clicked on, you would be directed to the post URL.

If that is correct, then isn’t that what google calls “duplicate content”. Also when you talk about double listings, do you mean the same content is indented on the SERP? or two different posts?

Finally, if I backlinked the main sticky post’s original deep URL like you suggest, does that count as backlinks to the home page too? As that post will be on the home page aswell?

Thanks Once again, Your time and help is very much appreciated,

Dennis
