vntourism.info
This is one of my website, I optimized it for SEO, the alexa ranks is 1.6m now and have hundreds of visits everyday
But it haven't got any pagerank, I don't know why.
The same to web-vn.com, kinhtetre.net and every page of mine, althought kinhtetre.net have more than 300 visits/day
What can I do to get a high pagerank for those?
