If Google understands your website's content in a structured way, we can present that content more accurately and more attractively to Google users. For example, our algorithms can enhance your search results with " rich snippets " when we understand that your page is a structured product listing, event, recipe, review, or similar. We can also feature your data in Knowledge Graph panels or in Google Now cards, helping to spread the word about your content.
Today we're excited to announce two features that make it simpler than ever before to participate in structured data features. The first is an expansion of Data Highlighter to seven new types of structured data. The second is a brand new tool, the Structured Data Markup Helper.
Support for Products, Businesses, Reviews and more in Data HighlighterData Highlighter launched in December 2012 as a point-and-click tool for teaching Google the pattern of structured data about events on your website—without even having to edit your site's HTML. Now, you can also use Data Highlighter to teach us about many other kinds of structured data on your site: products, local businesses, articles, software applications, movies, restaurants, and TV episodes. Update: Here's the full list of schemas supported in Data Highlighter.
To get started, visit Webmaster Tools, select your site, click the "Optimization" link in the left sidebar, and click "Data Highlighter". You'll be prompted to enter the URL of a typically structured page on your site (for example, a product or event's detail page) and "tag" its key fields with your mouse.
The tagging process takes about 5 minutes for a single page, or about 15 minutes for a pattern of consistently formatted pages. At the end of the process, you'll have the chance to verify Google's understanding of your structured data and, if it's correct, "publish" it to Google. Then, as your site is recrawled over time, your site will become eligible for enhanced displays of information like prices, reviews, and ratings right in the Google search results.
New Structured Data Markup Helper toolWhile Data Highlighter is a great way to quickly teach Google about your site's structured data without having to edit your HTML, it's ultimately preferable to embed structured data markup directly into your web pages, so your structured content is available to everyone. To assist web authors with that task, we're happy to announce a new tool: the Structured Data Markup Helper.
Like in Data Highlighter, you start by submitting a web page (URL or HTML source) and using your mouse to "tag" the key properties of the relevant data type. When you're done, the Structured Data Markup Helper generates sample HTML code with microdata markup included. This code can be downloaded and used as a guide as you implement structured data on your website.
The Structured Data Markup Helper supports a subset of data types, including all the types supported by Data Highlighter as well as several types used for embedding structured data in Gmail. Consult schema.org for complete schema documentation.
We hope these two tools make it easier for all websites to participate in Google's growing suite of structured data features! As always, please post in our forums if you have any questions or feedback.
