Google is sifting through the photos and commentary on its blossoming social network
so its Internet search results can include more personal information
The additional personal touches that began to roll out on Tuesday mark another step toward one of Google's most ambitious goals. The Internet search leader eventually hopes to know enough about
each of its users, so that it can tailor its results to fit the unique interests of each person looking for something.
Different people should start seeing different search results more frequently now that Google Inc
is importing content from its 6-month-old Plus service, a product that the company introduced in an attempt to counter the popularity of Facebook's online hangout and Twitter's short-messaging hub.
Google's main search results page will also start highlighting more content from an older online photo service called Picasa.
Other features will recommend additional people and companies to follow on Plus, based on their search requests. Those suggestions will exclude publicly accessible information about accounts on Facebook and Twitter.
The preferential treatment for Plus might amplify concerns about the objectivity of Google's search results - a focal point of broad regulatory investigations in the US and Europe.
The Federal Trade Commission, attorneys general in six states, and the European Commission are looking into complaints alleging Google has been unfairly exploiting its dominance in Internet search to promote its other services while ignoring or downplaying pertinent information about its rivals.
The exclusive Plus recommendations in Google's search results are "exactly the kind of thing that the antitrust people are screaming about," said Danny Sullivan, an industry expert who has been following Google since the 1990s and is now editor of SearchEngineLand.com. "This is very un-Google like. It's unfair to other services and it's unfair to people."
Sullivan's criticism is especially striking because he has generally defended other search features that highlight Google's own services.
Twitter said it's worried the added emphasis on Plus in Google's search results will make it more difficult to find breaking news and other compelling information shared within the 250 million messages, or tweets, posted on its service each day.
"We think that's bad for people, publishers, news organizations and Twitter users," Twitter said in a statement.
Facebook didn't immediately respond to a request for comment.
Google says its efforts to reel in more information from other sharing services are frequently thwarted by the providers. For instance, Twitter puts explicit instructions in its computer computing telling Google not to index the material, according to Google.
"Ushering in the new era of social and private data search will take close cooperation, and we hope other sites participate so we can provide the best possible experience for our users," Google said in a statement issued after it was asked about its added emphasis on Plus in its search results.
Facebook and Twitter pose a threat to Google because they don't allow Google's search engine to log most of the photos, links and observations cascading through those services. That's troublesome to Google because its search engine could become less useful if its system can't analyze what people are signaling is important to them so those preferences can be factored into the results.
Twitter once gave Google better access to the tweets flowing through its service as part of a 2009 licensing agreement, but that deal expired last summer. Microsoft Corp.'s Bing search engine is still paying to mine into Twitter's service.
Facebook has long cooperated with Bing, partly because Microsoft bought a 1.6 percent stake in the company in 2007. At the same time, Facebook has steadfastly resisted Google's attempts to peer deeper into its social network.
That's one of the reasons Google started Plus, which is now hatching "Search, plus Your World."
The feature will be automatically turned on for all English-language searches made by users logged into Google. Turning off the personal results permanently will require changing a setting in Google's personal preferences. The personal results can also be excluded on a search-by-search basis by clicking on an icon of the globe on the results page (the personal results will be denoted by a button featuring a human's silhouette).
If the new formula works as Google expects, the search results will include pertinent information culled from the requestor's Plus account.
While Google is hoping the addition of more personal results will make its search engine even more useful, the changes also could spook some people as they realize how much information is being compiled about them. Google tried to minimize privacy concerns by recently switching to technology that encrypts all its search results to protect the information from slipping out.
Previous privacy missteps by both Google and Facebook resulted in both companies entering into settlements with the US Federal Trade Commission. The FTC agreements require Google and Facebook to submit to external audits of their privacy practices every other year.
