Google +1 is another service of google by which users can share their favorites to the world by their google profile
Basically, Google +1 is a user-search based pointing system wherein you will mark the +1 vote on the websites that the user has searched online using keyword/s. Why it is helpful for the seos? mainly, it will help you to get your site listed on the web results based on the keywords that you and your friends used. Aside from that, you're site is gaining popularity once everyone marked your site and share it with their community/friends through the use of their Google profile. Its more like a social based results; but as to SEOs, its really helpful because we are gaining reputation without asking them to linked out.
Hello friend, Google +1 is that you can manipulate your search results for yourself and people connected by giving content you like your personal approval.
Google +1 service is another social media like service started by Google. There are many others present like digg, flike, reddit and many more to socialize the content. It might be a part of algorithm later while judging a site's value in the SERP. Google has also announced its social network . Here you can get the details about it http://bit.ly/kNqPAa
is is the same as facebook like button ? and if yes.. can people with no google + accounts can click on + 1 ?
Click +1 to publicly give something your stamp of approval. Your +1's can help friends, contacts, and others on the web find the best stuff when they search.
Google +: After the failure of Orkut and Google buzz, now the search engine giant has presented a new social networking site with advance features: Google+. It is still under development so we have to wait for using its full features. Google +1: It is just like facebook like. Difference is just of the creators.
There's a post on the official google blog about the project. http://googleblog.blogspot.com/2011/06/introducing-google-project-real-life.html.
so basically Google +1 can be very helpful to your site,more helpful than the 'Like' or 'Tweet' buttons..
I would think so as it gives it more of a social edge. Something google seems to be focusing more on recently.
