I have seen a lot of gigs on fiverr that offer to promote your link on
their facebook or twitter account. Has anyone had any success with these
type of gigs?
I was thinking about testing one or two out just to see what happens.

You have to know what you're purchasing — and the reason why you're purchasing it.
If you want social bookmarks, to boost backlinks for SEO purpose — Fiverr is great!
However if you want actual niche traffic that will convert, you won't
likely find that on Fiverr. Better to spend your $5 on a gig that gets
you backlinks to boost your organic placement, in turn getting you more
exposure and clicks via the search engines.
...unless your purpose for buying traffic is to "artificually" lower
your Alexa rating, which isn't beyond some, for whatever purpose.
