SAN FRANCISCO (Reuters) - Twitter lashed out at changes Google Inc unveiled for its search engine on Tuesday, describing the changes as "bad" for consumers and for Web publishers.
Twitter, a microblogging service which allows its users to broadcast short, 140-character messages to groups of "followers," said Google's changes would make it tougher for people to find the breaking news often shared by users of its service.
"As we've seen time and time again, news breaks first on Twitter; as a result, Twitter accounts and Tweets are often the most relevant (search) results," the company said in a statement.
"We're concerned that as a result of Google's changes, finding this information will be much harder for everyone. We think that's bad for people, publishers, news organizations and Twitter users," the statement continued.
Twitter's criticism, which came hours after Google announced new features aimed at making search results more personalized, underscored the growing competition between the Web companies. And it comes at a time when Google is facing antitrust scrutiny for favoring its own services within its search results.
A Twitter spokesperson declined to answer a question about whether the company might reach out to antitrust regulators about Google's changes.
Google did not immediately respond to a request for comment.
A 2009 agreement, allowing Google to offer a real-time feed of Twitter messages within its search results, expired in July.
Google launched a social network, dubbed Google+, in June that offers many of the capabilities available in Twitter and in Facebook.
With Tuesday's changes to Google's search engine, photos and posts from Google+ will increasingly appear within the search results.
The changes effectively create customized search results for people who are logged in to Google. A person who searches for the term "Hawaii," for example, might find private photos that their friends have shared on Google+ as well as public information about the islands.
Twitter General Counsel Alex Macgillivray, a former Google attorney, said in a Tweet on Tuesday that Google's changes "warped" Web search and represented a "bad day for the Internet."
