Earlier this month, Google had begun experimenting with displaying content from Twitter in desktop results.
In May, Google already had begun showing tweets in mobile search results — but now they also will begin to show to all English language searches on desktop.
Google told it is now rolling out to all users in English globally. Just like in the mobile results, Google will show Tweets in a carousel in the main column of the organic search results. The tweets only show when Google deems them to be relevant.
Users do not need a Twitter account to see the results or click on the results.
Google also said the relevancy and ranking behind these Twitter results will continue to evolve and improve as the process matures.
Currently, there is no advertising component to showing Tweets in the organic results.
