Google has regained the ability to use real-time tweets in its search results ending a four year absence of content from Twitter being shown in the search engine.
The new agreement between the two companies will see tweets appear for users of US users searching from either the Google app on iOS or Android, or from Google's mobile search page.
"The desktop web version is coming shortly, and we have plans to bring this feature to more countries in the coming months," Twitter said in a blog post.
Google said it would look to extend the arrangement to other languages in the future.
A prior arrangement existed between the two companies from 2009 to 2011, but Twitter chose not to renew it. Microsoft's Bing search engine already has a deal with Twitter to show tweets in its results.
Earlier this year it was reported that no advertising revenue would be exchanged between Google and Twitter for this new deal.
