A new development from Google Search allows businesses (or potentially individuals) to have their social links appear in Knowledge Graph powered Google search results. From a marketing perspective this is another bit of awesomeness from Google. Like many things though you have to 1; know about it and 2; implement some code on your website to make it happen.
For most businesses, social networks play a very important role in their ongoing marketing efforts. From content distribution to customer acquisition and retention each business uses their social networks in their own way. Social links can therefore be almost as important as the link to their website. That is why it is great to have one more opportunity to put those social links in front of people who find you on Google search. It gives searchers multiple ways to connect to your company right from search.
In the image you can see the results for a search I did on the company Vistaprint. The Knowledge Graph search result box can contain data pulled from multiple sources including Google+, Wikipedia and Schema.org markup on the website of the business. In this case it looks like data presented came from several of these sources.
What is actually displayed in the Knowledge Graph search box and elsewhere on search depends on what information is available and the query made by the searcher. So, while it is best to have as much information as possible available to the Google search engine, it may not use all of the information in search results every time.
Even so, having your social networks or a custom search box appear within your search listing is pretty cool and definitely worth the time it takes to do it. If you want to include the proper markup so that your social links can be displayed in search results Google tells you how to do it at this page. If you need help with implementing this markup on your site we will be happy to lend a hand.
