I bought 2 link kings, results:
link king #1:
pos 15 > pos 6
link king #2:
pos 20 > pos 7
these are on sites with only 2 articles. ill be adding more content later for the SERPs boost, but this is a great seller with great communication.
you're getting the best kind of links for a cheap price (web 2.0s, articles, social bookmarks, and tier 2 links)
will buy again in the future
