I have to agree with Geester1. Nothing quite like original content and regular updates that Google can find.
There is no any software for increasing the page rank , You can get by making dofollow back link and good content.
No software can get you Page rank, of course not within a month. PR is only updated ever 3 months, as said by others above. Stay away from any such softwares. PR can only be achieved through good and quality on-way backlinks pointing to your site. The higher the PR link pointing to your site, the better would be your pagerank during next update.
yes, there is sone technique to make PR but only fake PR However, you can get PR3 within a month if you are doing great on link building and your timing is right
PR 3 in a month...is not very possible. I think long term sustainable development is the best solution.
You can get PR3 in a month only if you have many quality backlinks from sites with high PR and work on creating useful an unique content.
Or you can buy million of spam and irrelevant backlinks. I know people who get even PR5!!! for their sites in a month. Yes, you get fake PR, but some webmasters use this strategy (in short term perspective).
Pr means google gives your good value to your site. If you use auto software's to get the pr, that will not work with your website. Doing the work manually works better than any other softwares.
