  1. 1.    Google +1 Reference Guide 28, 2011By Joseph OleshThe +1 button from Google is similar to the Facebook “Like,” but applied to the entire web. Googledominance as the preeminent search engine places much value in this button. Businesses of everyindustry are scrambling for information regarding its functionality and application.Breaking news from Mashable’s Ben Parr explains that an update from Google this last Tuesday willmake the button even faster and more efficient. He cites Google software engineer David Byttow: “We’vebegun to roll out a set of changes that will make the button render up to 3x faster on your site,” Byttowsaid in a blog post. “No action is required on your part, so just sit back, relax, and watch as the buttonloads more quickly than before.”The following guide should answer most basic questions regarding the application and functionality ofGoogle’s +1 button. To install the button, grab a snippet of code here:  
  2. 2. The +1 Button & Search ResultsHow does +1 affect search results?+1 helps people discover relevant content—a website, a Google search result, or an ad—from the peoplethey 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 thecontext of Google search results.When a signed-in Google user is searching, your Google search result snippet may be annotated with thenames of the users connections whove +1d your page. If none of a users connections has +1d yourpage, your snippet may display the aggregate number of +1s your page has received.Does +1 affect my site’s performance in search?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 yourtastes can be even better. Because of this, +1’s from friends and contacts can be a useful signal toGoogle when determining the relevance of your page to a user’s query. This is just one of many signalsGoogle may use to determine a page’s relevance and ranking, and we’re constantly tweaking andimproving our algorithm to improve overall search quality. For +1s, as with any new ranking signal, wellbe starting carefully and learning how those signals affect search quality.How will the +1 button affect my traffic?Personalized annotations next to your page in search results may increase your site’s visibility and makeyour site’s snippet more compelling, which may in turn increase the odds that users will click through toyour page.Will +1’s from my site show up in search results?If a user +1’s a URL on your site, the Google search result snippet for that URL may be annotated insearch results and search ads.However, your site may make the same content available via different URLs. For example, your site mayhave several pages listing the same set of products. One page might display products sorted inalphabetical order, while other pages display the same products listed by price or by rating. For example: Google knows that these pages have the same content, we may index only one version for our searchresults. As a result, +1s for the other versions may not appear in search results.You can make sure Google displays +1 annotations for the most search results possible by adding therel="canonical"property to the non-preferred versions of each page. This property should point to thecanonical version, like this:<link rel="canonical"href="">This tells Google: "Of all these pages with identical content, this page is the most useful. Please prioritizeit in search results."Now, when a user +1’s a page with a non-canonical URL, Google will associate that +1 with thecanonical, preferred version.  
  3. 3. How does the +1 button affect my ads?The +1 button itself will appear next to your headline on search ads. Personalized annotations will appearbeneath your Display URL. For example, Maria +1s a page selling a neat laptop holder on a website.When a search ad with that same URL appears, her friend Sam might see the ad with the note "Mariaand 28 other people +1d this."Who sees +1?Who can see the +1 button in Google Search?The +1 button shows up for signed-in users of using a modern browser.Who can see annotations from +1 buttons?Everybody can see aggregate annotations. Signed-in users also see personalized annotations from:• People in their Gmail (or Google Talk) chat list.• People in their My Contacts group in Google Contacts.• People theyre following in Google Reader and Google Buzz.• People with that user in one of their circles in Google+.Will users on mobile browsers see the +1 button?We are not including the +1 button on mobile search results at this time. However, users may be able tosee any +1 buttons you have added to your web pages.Are +1s public?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 +1s on their Google profile.Adding the +1 button to a siteHow do I add the +1 button to my site?Just grab a snippet of code from should I put the +1 button on my pages?You know your page and your users best, so we recommend putting the button wherever you think it willbe the most effective. Above the fold, near the title of the page, and close to sharing links is often a goodlocation. It can also be effective to place the +1 button at both the end and the beginning of an article orstory.+1 is a public action, so you should add the button only to public, crawlable pages on your site. Once youadd the button, Google may crawl or recrawl the page, and store the page title and other content, inresponse to a +1 button impression or click.Can I place multiple buttons on a single page that all +1 different URLs?Yes, but youll need to edit the button code. Use the href attribute to specify the target URL. For example,if your home page has a module linking to your blog, and you want to add a +1 button to that module, editthe value of the href attribute to point to your blogs URL, like this:<g:plusone href=""></g:plusone>What languages is the +1 button available in?The +1 button and annotations are available in 40 languages.How often will Google crawl my +1d pages?+1 is a public action, so you should add the button only to public, crawlable pages on your site. Once youadd the button, Google may crawl or recrawl the page, and store the page title and other content, inresponse to a +1 button impression or click.  
  4. 4. How does +1 work with Buzz? Do we still need the Google Buzz button?Buzz buttons are used for starting conversations about interesting web content ("Hey guys, what do youthink about this news story?"). +1 buttons recommend web content to people in the context of searchresults ("Peng +1’d this page"), and +1s from social connections can help improve the relevance of theresults you see in Google Search. You can use the +1 button, or the Buzz button, or both—pick what’sright for your content.Some of my users get a security warning when they view pages with the +1 button. How do I getrid of this?The +1 button code requires a script from Googles servers. You can include this script using either http://or https://, like this:<script src=""></script>If your web page uses https://, some browsers and verification tools will show an error when any assetson the page are called via http://. If your site serves pages via https://, make sure that the +1 button codeon those pages also uses https://. (In fact, its fine to use https:// in the button code for all pages, even ifthey are only served via http://.)Configuring the +1 buttonWhat button sizes are available?+1 button icons can render at four heights: small (15px), medium (20px), standard (24px), and tall (60px).The small, medium, and standard icons can render with or without a total count of +1s. The tall iconalways includes a total count of +1s.What does the "Language" drop-down control?The Language dropdown controls the language of the button itself.http://www.Tier10Lab.com
