In a blog post, Twitter said, “Twitter Trends capture the pulse of the planet. We want to make it easy for anyone in any part of the world to find out what is happening around them, and Trends make that possible.”

The decision to include the three Israeli cities came as Twitter added another 50 urban locations to the Trends feature, accessible by entering #Jerusalem, #TelAviv or #Haifa in Twitter’s search bar or re-setting your location to reflect your favorite of the three Israeli cities.

In its online help section Twitter explains the Trends feature: “Trends are determined by an algorithm and, by default, are tailored for you based on who you follow and your location. This algorithm identifies topics that are immediately popular, rather than topics that have been popular for a while or on a daily basis, to help you discover the hottest emerging topics of discussion on Twitter that matter most to you.”

“You can choose to see Trends that are not tailored for you by selecting a specific Trends location on Twitter.com,” it says. “Location Trends identify popular topics among users in a specific geographic location.”

To use Twitter Trends in posts, the social media company says, “Just post a Tweet including the exact word or phrase as it appears in the Trends list (with the hashtag, if you see one). Due to the large number of users tweeting about these specific Trends, you may not always be able to find your particular Tweet in search, but your followers will always see your Tweets.”
