Friday, November 4, 2011 : The aim is to better deliver more up-to-date results…and it could impact 35 percent of internet searches
The introduction Thursday of a new Google search algorithm has been examined by the techie publication TechCrunch, which concludes that the changes will impact 35 percent of Web searches, building on top of the search company's previous “Caffeine” update in order to deliver more up-to-date and relevant search results, specifically those in areas where freshness is an imperative.
"This includes things like recent events, hot topics, current reviews and breaking news items," TechCrunch points out.
The new algorithm knows that different types of searches have different freshness needs, and weighs them accordingly. For example, a search for a favorite recipe posted a few years ago may still be popular enough to rank highly, but searches for an unfolding news story should bring the newer, fresher content first, followed by older results.
For searches about recent events and news, Google may now show search results towards the top of the page that are only minutes old, the company says.
Google was already ranking news items and stock symbols at the top of the page when users performed financial-related searches or searches for current information, but this algorithm change has an impact on the organic search results, too, not those from the verticals which have been integrated into Google’s Universal search.
“Given the incredibly fast pace at which information moves in today’s world, the most recent information can be from the last week, day or even minute, and depending on the search terms, the algorithm needs to be able to figure out if a result from a week ago about a TV show is recent, or if a result from a week ago about breaking news is too old,” said Amit Singhal, a software engineer who heads up Google’s search-ranking team.
While this week’s algorithm changes still don’t incorporate Twitter content, they do ensure that, for about a third of all Google search results, the most recent results will show up near the top of the page.
