Whenever I ask this question, How to increase page rank for any website? the only answer I get from all around is "get relevant/quality do-follow backlinks" to your site.
Visit this website www(dot)hkgrox(dot)com, it got PR 3 but you see it's got only 4 backlinks as per Google. So my question is how is it possible? I mean only 4 backlinks and PR 3 seems quite irrelevant what seo experts usually tells you.
What are your opinion here, why this site got PR 3 with so less backlinks? Eager to see you response.
