Welcome to WebmasterWorld Guest from 220.127.116.11
At Google we're making more and more use of structured data to provide enhanced search results, such as rich snippets and event calendars, that help users find your content. Until now, marking up your site's HTML code has been the only way to indicate structured data to Google. However, we recognize that markup may be hard for some websites to deploy.
Today, we're offering webmasters a simpler alternative: Data Highlighter. At initial launch, it's available in English only and for structured data about events, such as concerts, sporting events, exhibitions, shows, and festivals. We'll make Data Highlighter available for more languages and data types in the months ahead.
Data Highlighter is a point-and-click tool that can be used by anyone authorized for your site in Google Webmaster Tools. No changes to HTML code are required. Instead, you just use your mouse to highlight and "tag" each key piece of data on a typical event page of your websiteGoogle Introduces Data Highlighter For Event Data [googlewebmastercentral.blogspot.co.uk]
Usually, 5 or 10 manually tagged pages are enough for our sophisticated machine-learning algorithms to understand the other, similar pages on your site.
I should have also added that all this stuff can probably already be accomplished by implementing the schema markup tags if I'm understanding this thing properly?
So, why force yet another layer of work on top of us?
