What is the relation between Google plus one and Page Rank?

- Google plus is a social media site powered by Google and it is very effective for SMO.

- I like Google+ and it's growing daily. It's not going to compete with Facebook yet, but still it has 90M+ users.

I like the interface. Once you get used to how it all works it really is intuitive and powerful. The sharing capabilities an being able to effectively segment people by putting them in different circles is fantastic.

- The Google Search pages now have an option for all searchers called "Search plus Your World." If you've joined Google Plus, your Web pages can be seen high on the search results pages by other G+ members. It's nice, additional exposure for G+ members.

- Google + is a service that is social networking also crated by Google. create your account in Google and share your thought.

- As far as i know there is a correlation between Google and Page Rank, but not with quantity of +1's on your site and it's PR. You can use Google+ for promotion of your website and then will get higher PR, that's right.
