In this above article. when I entered just three keywords in google:
This article comes on the first place.
Please help me understand the reasons as why only just by these three keywords?
My observations : I researched and observed that the phrase "increase position" have global searches of 110 (by doing phrase type search in google keyword tool) and very low competition. Does it means that the article is covering users who use increase position as a phrase to search answers for their site making them use the three keywords (increase, site, position) to ask the query.
