They're called mini-sitelinks, and Google decides when to display them. Here's a post from when they first debuted: http://readwrite.com/2009/04/16/google_gets_sitelink_one-liners

No problem! Also, one other factor is that even if you did know that they didn't pay FB to boost, you don't know if there was a third-party service they used to get likes.

Unless it happened to show up in your feed (in which case you can see a note that it was sponsored), to my knowledge, there's no way of knowing it was paid. I asked Marty from Aim Clear and a couple of other people about this last spring, and they weren't aware of a way either. If one post has 3000 FB likes, and all the other posts by the page have about 10 likes, you can guess that they did something, however.

Google is getting much better at reading javascript, however.

Also, are you planning on paying $1 or so to get into the user's regular inbox? If not, you may wind up in their "other" mailbox, which many people don't know even exists.

Why not try Facebook advertising instead?

I noticed you had similar questions at http://moz.com/community/q/unique-content-below-fold-better-move-above-fold and http://moz.com/community/q/risk-using-nofollow-tag with several answers each, including some that were marked as Good Answer. Did any of those answers help to answer your question?

Hi Laurean,

Thanks for the answer! I wanted to make sure that you knew this was an older post (from February of 2011), so you may not be hearing back from the original poster at all regarding their question.
