For the last few years SEO’s have manipulated which websites will rank better in Google or any other search engine. But with launch of Google+ it seems that the power of search ranks is back in the users’ hands. The +1 button empowers the user to make decision about how good the content really is.
For instance, if an article receives a big number of pluses from website’s users, then Google will reorder the information, generating the results based on the number of pluses, which should be indicating the quality of the content. And moreover, your Google+ friends would be able to see what you are recommending, namely what you have “plused”.
When they are searching for something, they will see an image of you within the search results, and the information would probably seem more trustworthy and reliable to them, since it is recommended by someone they know.
Also, if you follow some basic SEO (search engine optimization) guides, you will see how important social media is. And what is Google’s social media weapon? That’s right, Google+.

Author Profiles in Google Search
Another interesting feature that the +button brings is the association between an author‘s profile and the content he posts. When searching for an article, the author’s profile will appear on the right of the search engine results, thus establishing authority in the web.
The +1 button, pretty much like the Facebook “Like” button, could also be an indicator of you’re your friends’ taste, interests, activities or hobbies.
Despite the fierce competition between Google + and Facebook, one shouldn’t be choosing one instead of the other, but rather use both of them. Of course, for the moment, the former only counts 20 million users, while the latter reached a staggering 750 million. Plus, it seems that the amount of time spent on Facebook is almost four times the time spent on Google Plus. But the newly launched social site should be given a chance to prove what it can actually do.
The + 1 button really seems to improve search results in a fun, yet productive way. As more users will enter the Google Plus world, the more accurate and interactive the search results could be.
