my site has recently been enjoying a very good improvement in its page rank with the help I received in the form of very well, but expensive ISP. It has leapt to the page rank 6 to 8 page ranks. I was enjoying the benefits of it and a lot of traffic in my website in the future. The thing that bothers me now, I still want to further improve my site a go. What advice you can give me this question? I should get an independent ISP? This will do more good than hurt my page rank?
