Yahoo has turned on deep links and images from Wikipedia in its search results as part of its overall effort to add structured data from third parties via the Search Monkey platform.
What this means – when a Wikipedia result is returned for a query (and this happens a lot, see this search for TechCrunch for example where it is the second result), Yahoo will include deep links to the first four sections of the article, an image if it’s available and a text summary. I’ve added a before and after image for the TechCrunch search below.
The new Wikipedia module is turned on by default, along with existing modules for Flickr, Yelp, LinkedIn, CitySearch, Zagat and others. Any of the modules can be turned off here.
