The relation between +1s and rankings
SearchMetrics found a similar, only stronger, relationship. They found Google +1s as the most highly correlated ranking factor.
A Qualification from Moz
The folks at Moz have qualified their statement by proposing that Google may not actually use your +1 count for rankings, but rather your postings on Google+ itself. We think both are valuable.

Correlation Doesn’t Imply Causation … But Wait!
It’s true that just because two things are correlated that doesn’t mean that either one causes the other. It could easily be the case that both are caused by the same other factor or group of factors.
Despite that, Moz thinks there is a causative factor here, particularly between Google+ postings and rankings. They point out that Google+ has qualities that make it a superior platform for SEO than Facebook, Twitter or other social media. Google+ was designed to power real-time search after Twitter cut off Google’s access to tweets in 2011. Some of the advantages of Google+ include
- Google+ posts are crawled almost immediately when they’re published.
- Posts on Google+ pass link juice (or PageRank), unlike Facebook and Twitter.
- Google+ is optimized for semantic relevance — it has many of the characteristics of a full blown blog. For example, the headline of the post becomes anchor text for the link and each post has its own URL, unlike other social media platforms.
They follow up with a 9-point program you can follow to take full advantage of Google+ for your business. I recommend the entire article.
