My page rand suddenly went to a 3 and then to a 4 on my homepage with some pages in my site getting pr of 2 or 3. I am trying to figure out what caused this. Here are steps I have taken in the past 3 months. 1 Submitting 30 articles to several social bookmarking sites and putting icons for people to submit my articles to social bookmarking sites 2.My site has a blog within it. 3.I am using something called Content 2.o provided by the company that furnishes the web platform I amusing so your an content on my articles, however there are not many comments on my site since setting this up in January. 4.article distribution to many sites using an online article distribution site. Which of these task were the most likely to have increased my pr and which did not really help with that aspect of things?
