PR0 vs PR2
 

Hi, I have PR2 website and it was first in search results. Recently, competitors website with PR0 jump to first position for 2 weeks now! How it is possible?

Google rarely update the PR, so they may have a higher ranking or PR, but still not updated.
Anyway, Google did update the PR during this month (December), check the PR again.

PR is not a major factor to up ranking blog in SERP. Maybe website PR0 have quality backlink, content and something else that can improve that website to the first result in search engine.

I also think like you. There are external PR and PA DA again

may be he have high PR on page then your Page PR.

PR is not alone factor for ranking. In-fact Google wants to drop it at all. There are many other factors for ranking. Might they have better quality than you Improve your website and content.

Google PR is not the only factor of SEO

PR is one of many factor that google take into considération to ranking websites.

What is PR0 and PR2..How are they useful for us...?

Are check what is your competitor did? or what kind of practices was help him get top on google? Do some competitor analysis about your competior like which kind of practice he was doning, what kind of backlinks he have.. etc. And try to do same practice for your website

everything possible with seo ...
