Starting this week, Google will present search results in the order in which users are most likely to prefer, based on their recent search histories.
In a blog post, Google's director of search product management, Johanna Wright, said Google is now better able to provide the most relevant results using analysis of 180 days of Google search activity from users' browsers.
If someone always searched for ADA and often clicked on results about the programming language, Google might show them those results before it showed results for the American Dental Association, for example, she said.
Also starting this week, Google will automatically deliver search results based on what it thinks users meant when they typed in their search terms.
"When we have high confidence that your query was misspelled, we go a step further than asking 'Did you mean...' by automatically showing results for the corrected query, saving you a click," Wright said.
The results page will have a link back to the original query in case Google guessed wrong, she said.
Google also added tools so that webmasters can see how quickly their sites' pages load. "There are also recommendations on how to improve your site's performance based on our GFast plugin," Wright said.
Wright said Google now supports searches in 40 languages, the latest being Bulgarian, Croatian, Czech, Hebrew, Hindi, Hungarian, Indonesian, Latvian, Lithuanian, Romanian, Serbian, Slovak, Slovenian, Filipino, Ukrainian, Vietnamese and Greek.
It has also added a translated search tool to the Search Options panel. This let users see results from other languages for their searches.
"We will automatically determine the best languages to translate your query into, then search and translate the results into your language," Wright said.
In future, results will also show the country of origin for the page retrieved, where Google could establish it, she said.
