: How does a plus one on a post carrying a link, help for SEO? How does a +1 on a post (from Google Plus) that carries a link help for SEO? Will it help the PageRank in Google? If yes,

@Angie530

PageRank alone != SEO.

Google attempt to rank by relevance, and PageRank is a single signal of that.

Google rarely reveal all the signals they use to rank a site, but the fact they own all Google Plus' data, would mean I would find it would be odd for them not to mine it to help improve their search results.

A popular site will be +1d, retweeted and liked - which are all good signals that a site is popular though, like links, open to abuse from spammers.

It is also good free advertising. Who cares how people find your site (whether it be via a Google Plus profile or via search), as long as the right people do so.

At one time, you were able to get DoFollow links from Google Plus. However, that has since been "fixed" and nofollow has been implemented on all external links.
For the past four or five years, the term "Social Signals" has been used to describe links/likes/shares from social networking websites. It is believed that these social signals can have an impact on your website's search rankings.


All in all - One share (+1) probably has a very minimal impact. However, social links are great in the sense that they can have a knock-on effect. i.e. Person visits your website via a link on Facebook and likes the content so much that they share it on their blog (not to mention the fact that nofollow links are a vital part of a healthy backlink portfolio).
