The list below will tech you how to improve your Google page rank. They are all very easy and simple to do but will prove effective in the long term for your Google page rank;
Submit to Directories
Submitting to High Page Rank directories will definitely help boost your Page Rank. I have put together a free web directory list HERE. Don’t submit to to many at once as it will decrease your page rank due to flooding Google with your links. Submit to no more than 20 Per day! Once you have done this for a few weeks you will notice after the page rank update that your page rank will have gone up.
Back-Links
Getting back links is the most effective way of getting your page rank up. Try to get webmasters with good Page ranks to put your link on there blogroll. Try to get a few high page rank backlinks rather than lots of no page rank baclinks. Sometimes you might have to pay them a few dollars but its worth it. Before submitting your link you should check there page rank. Use this TOOL if its page rank 3 or higher then I would recommend placing your link on their site or blogroll. Try not to exchange links to many times as they cancel each other out. Normally you just exchange links for traffic!
