Since its inception, Google has strove to bring the most relevant search results for its users. The latest iteration, “Search Plus Your World,” blends their traditional search with Google+.

What Changed?

For those who have a Google+ account, searching Google will now draw both personal and non-personal results. When you’re logged in and perform a search, the results might look like this:

The orange arrow points to where you decide whether you want to view Your World results. With it on, Google finds photos, links, videos and other content that your network has shared.

So will it work?

Search + Social has been a talking point for some time already. Google has released several properties that nudge the process along like the +1 button. This represents the clearest combination of the two, but there remain a few hurdles to widespread adoption:

1. People need to share on Google+ - A lot of Google+ users signed up because they used other Google Apps like Gmail, Docs, or Reader. But a lot have undeveloped networks without a high volume of sharing. Without that sharing, search results won’t pull relevant Your World results.

2. Intrusion on Google Search – Clearly, a lot of people like Google Search. Messing with the results that people expect threw some for a loop. Though users can easily turn off the Your World option, many will be left wondering why they got back personal results.

3. Forced Hands – Your World further forces brands to get involved on Google+. Having a presence is now a very important part of SEO.
