Google +1 has been recently launched, you can read our article which tells you how to use it and how to enable it on your google account profile. As this feature is fairly new, so we are posting all the possible questions and answers about google +1, read on further to clarify your doubts.
The +1 button and search results
+1 helps people discover relevant content—a website, a Google search result, or an ad—from the people they already know and trust. Adding the +1 button to your pages lets users recommend your content, knowing that their friends and contacts will see their recommendation when it’s most relevant—in the context of Google search results.
When a signed-in Google user is searching, your Google search result snippet may be annotated with the names of the user’s connections who’ve +1’d your page. If none of a user’s connections has +1’d your page, your snippet may display the aggregate number of +1’s your page has received.
We’re currently testing +1’s with a small number of users searching in English on Google.com. Signed-in users may see personalized annotations from their social connections, which include the following:
- People in their Gmail (or Google Talk) chat list.
- People in their My Contacts group in Google Contacts.
- People they’re following in Google Reader and Google Buzz.
We’re currently testing +1’s with a small number of users searching in English on google.com, and using a modern browser. Signed-in users may see the +1 button in search results.
Content recommended by friends and acquaintances is often more relevant than content from strangers. For example, a movie review from an expert is useful, but a movie review from a friend who shares your tastes can be even better. Because of this, +1’s from friends and contacts can be a useful signal to Google when determining the relevance of your page to a user’s query. This is just one of many signals Google may use to determine a page’s relevance and ranking, and we’re constantly tweaking and improving our algorithm to improve overall search quality. For +1’s, as with any new ranking signal, we’ll be starting carefully and learning how those signals affect search quality.
Personalized annotations next to your page in search results may increase your site’s visibility and make your site’s snippet more compelling, which may in turn increase the odds that users will click through to your page. We’re working on ways to provide webmasters with more data about the impact of +1 on their site’s performance in search—stay tuned for updates!
Yes, Google may show personalized annotations to any signed-in user who has a social connection to a +1. However, any Google user can choose whether or not to display their +1’s on their Google profile.
Google doesn’t share personal information about people who have +1’d your pages. However, in the future we may provide aggregate demographic information about your +1 audience—for example, that 20% of your audience is in New York.
