Hi, I have question regarding to add pages to a website. In one of my site which already had home page PR-4 (before recent PR updation ) I had added 20 new well optimised pages to that but in recent PR updation PR dropped from 4 to 2. And also for one of my blog's home page PR dropped from 3 to 2 but all of internal pages PR increased for theh blog from n/a to 01. I also like to mention that I have not done any bad practices. So, Do adding new pages effect Home page PR because of PR distribution to internal pages. for an example: If i have a website with home page PR-4 and already have90 pages and then if I add 20 more pages to my website so is there any possibility of dropping PR of homepage because of PR distribution to internal pages.
