Twitter to Offer Marketers More Tools to Target

"Geo-relevance for promoted tweets and accounts allows marketers to reach the audience in the right geographic areas," said Adam Bain, Twitter's president of revenue. "A regional chain that is only available in a certain part of the country can now promote their account or tweets in the right metro areas. If you want to advertise against the term 'jeans' to people in Cleveland, you can now do that. Tweet by tweet by tweet, for each organic and paid tweet, we're able to tell you how it's resonating, including follows and unfollows, so you can tell if you're turning off your followers."

Geo-targeting on Twitter is available in 210 cities in the U.S. and more than 100 countries, Mr. Bain said, adding that Twitter will be adding more cities and countries over the coming year.
