Google +1 Button | Social Search Marketing
The +1 button is a shorthand for "this is pretty cool" or "you should check this out." Click +1 to publicly give something your stamp of approval. Your +1's can help friends, contacts and others find the best stuff when they search.
We have seen the power of Social Media sites like Facebook and Twitter create a “social web,” and the social networking was all about sharing interests, websites you love, and articles you found that were interesting. However, all of those things were confined to their corresponding platforms: Twitter has its trend topics and its hashtags, Facebook has its “Likes” and “Shares.”
For marketers, the" Likes" and "Re-tweets" drive revenue when their content is re-distributed on social networking websites.
Google has taken this same sharing system but they gave it a minor tweak: instead of sending those articles, videos, songs and images to your profiles inside of a social network, you’ll be using a button to recommend those pages through your Google account. This, ultimately, will be reflected on the Google searches, which now will be more “social” and will show results of a higher quality and more appropriate contents, also bringing more relevant and more popular searches to the front of the line.
The key element to +1 is relevance. Google is trying to develop a way with which your searches for any topic will give you more relevant results.
How Does +1 Affect Search Results?
Google Plus 1 helps consumers discover relevant content—a website, a Google search result, or an ad—from the people they already know and trust. Adding the Google +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—similar to how the Facebook "Like" button works, but this is displayed 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.
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 search query. This is just one of many signals Google may use to determine a page’s relevance and ranking.
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. It works in the same way as product reviews do—consumers are more inclined to select a product that other consumers have used and provided good reviews on.
