Hey guys pretty much what I'm looking to do is try and find/collect researchable reasons to help me explain an increase or decrease in PR. So far I've tried researching the following possible explanations as to why a site's PR would increase or decrease with all my results coming up inconclusive (for my site). 1) Backlinks (I used Site Explorer) - Increase or Decreases in Backlinks - The PageRank of these backlink and whether or not they are nofollowed - Researched relevancy of Backlinks to the pages themselves. (For me, all results were inconclusive in this area as my pages whether PR1 or PR5 had a VERY similar if not equivilent backlink profile.) 2) Site Traffic (Google Analytics) - Increases or Decreases within the time frame from the previous PR Update to the Current Update 3) Changes Made to Pages - Research any possible changes to on-site within the time frame from the previous PR Update to the Current Update 4) Page Speed - Researching the Google PageSpeed Score for each page (not sure if Google started implementing this yet or not, but I figured it couldn't hurt.) 5) Social Media Mentions - Using a couple tools I've tried researching the number of times certain pages or products were mentioned on Social Media websites (i.e. Twitter, Facebook, Digg, etc.) 6) Product Conversions - Using Omniture I checked to see whether and increase in conversions could have possibly resulted in an increase in PR. (I personally know this is a bit extreme, and Toolbar PR shouldn't be used as more than a thermometer, but its one of those things that has to be explained to higher ups.) Do any of you guys go through such extremes to try and explain increases or decreases in PR, and if so are there any other options you think I should try?
It's no.1 The other things will have no effect on PR, and your traffic and conversions will have no effect on serps.
Well yes I understand this, but how do you explain a decrease when the backlink profiles of your pages are essentially equivilent to eachother. For example a PR1 page has the exact same number of PR4 and PR3 Backlinks as a PR5 page. Since I'm not really sure how to explain that, I was wondering if there was another way to explain this or another piece of information I could research in order to find an answer.
PR is all about Backlinks, and based on the linking page/site quality the number of backlinks is not the only factor to consider.
Well I've considered the number and quality of my backlinks (from the previous Toolbar update to the current Toolbar update, in which the quantity of my backlinks continuously decreases for most of my pages) and still I'm unable to explain the reason for an increase or decrease in PR. As I've said previously all pages have an almost equivalent backlink profile so an increase can't be explained, only a decrease as I've continued to lose backlinks.
As all of you know that PR completely depends on back links,the increment or decrement completely depends upon the quality of links you've made after the previous PR update..
I think the updating also play a part. The blog posting and the comment all play a part. Since each comment added mean the page has to refresh once, the blogger can get away with a monthly posting if there is a new comment every day.
