It's Googles lame attempt at going up against facebook likes.  Much like Googlewave "the twitter killer"

Unless Google finds a way to make this really cool, I don't think it will have much success.

Might take a while before we can really feel any changes. Facebook is still king of Social Networking. Doubt that it will change soon. But knowing how Google go about things, it is quite possible.

How Google+1 works is when you +1 a site or page under your Google account, and later a friend or connection in your circle searches for the same thing, they'll see a little icon and text below the result that says "Loren +1'd this". The idea is that the person searching will be much more likely to go to your site seeing a connection's +1.

So, if your site's valuable and you get a lot of +1s, you encourage their circles to click over to you. That has the potential to be huge. The +1 sites they clicked on also show up in their Google Plus profile.

Does all of this help SEO? I guess it can. SEO is about optimizing for search engines, and if your site shows up as a recommended or +1 page by many people, you can possibly get more visitors. With Google being king of the search engines, you can get a lot of free traffic this way.

It certainly doesn't hurt to get the button. I'll be getting it myself very soon.  

I think that Google's +1 integration with search engine results is an attempt to push users to create Google Plus accounts. From what I've seen so far, the +1 button doesn't affect website rankings very much. I have a few sites with hundreds of +1s  and haven't seen any dramatic improvement in search engine rankings. If +1s do hold any amount of weight in the search engine rankings, it's very minimal. Instead of worrying about +1s, everyone should be taking a look at what Google's Panda update has changed in terms of their search ranking algorithms.

If you own a website and want social activity, and deep indexing you better learn to embrace Google Plus.  Google rules the house, this is their way of implementing social activity into their ranking algorhythm.  I think its pretty cool, the circles formula actually works for getting traffic to your site.  Plus you can have a google group and use it for a discussion.  I am going to start one for this very sites topic, it should be an amazin tool.

It's a similar idea with Mark's like button. However, it would be very hard to translate the functionality of this button into a really useful one. Besides, the probability of seeing the same site visited by your "friend" displayed in the search results is slim.

My Google+ experience has been that the same 3 people are still using it consistently, but it's nice to see personalized search results based on connections.

Google+ is Google's new social networking. At the first look  Google+ looks like combined site of leading social networking site Facebook and twitter. But having some excellent features.
