Twitter will soon show its U.S. users ads based on the Web sites they’ve previously visited.

Wednesday, the information network formally announced that it is experimenting with a new ad type it calls “tailored ads.” With the units, advertisers can upload browser cookie IDs or email databases to push their promoted messages to people who have already shown interest in a particular brand or business.

“Users won’t see more ads on Twitter, but they may see better ones,” Kevin Weil, senior director of product revenue, said in a blog post.
