As a technical reference, the term rich snippets describes structured data markup, which site operators can add to their existing HTML. This structured data markup allows search engines to better understand what information is contained on each web page. The major search engines now have the capability of displaying this structured data in an enriched and visually compelling format for your visitors on the search engine results page (SERP).
People – you may have noticed Google and Bing now showing richer information from LinkedIn when you search for certain (well-known) people. Similar results are possible for any website that includes profiles of staff, team members and other people relevant to the organization. Supported rich snippets properties include name, title, role, professional affiliations, and contact details.
Products – one of the single most important uses of structured data markup is with products and special offers of merchants, particular online stores. Properties available include name, image, brand, description, identifiers (ISBN, SKU, etc.) and even reviews, all extendable with price, currency, seller, condition, and quantity. Online marketplaces that offer the same product from multiple merchants can use “lowPrice” and “highPrice” to show the price range for a single item.
Businesses & Organizations – rich snippets properties available include business name, address (physical and URL), telephone number, geo-location (latitude and longitude) and logo.
Recipes – structured data markup for recipes offer a multitude of properties, allowing operators of websites related to cooking and recipe collections to include everything from the type of dish, reviews, preparation, cooking time, as well as nutritional information such as serving size, calories, fat content and more.
Event & Class Schedules – the usage of structured data markup with events is intended only for future occurring events, not past events. It is worth noting here that the property summary is not intended for a summary of the event, but for the event’s official name. Other properties include start and end date, duration, ticket details and geo-location.
Music – Google makes provisions for structured data markup relating to songs and music albums. This can include links to previews of songs, and direct links to buying individual tracks or full albums.
Video Content – this applies to embedded video content on your website and can be used to indicate duration, license, production company and/or the creator of the video, and even if the content (must be family friendly).
Talk to your webmaster how to implement these structured data markups within the framework of your individual website configuration. The SEO and user benefits of rich snippets far outweigh the cost of configuration.
