Last month, Twitter unveiled tailored audience, an ad retargeting tool that gives marketers the ability to track mobile users who have browsed for specific products and services even outside of its site.

Tim Jensen, senior web strategist at digital agency Overit said B2B marketers will be able to get a lot of mileage out of the new tool.

“Remarketing is very valuable—when set up properly it can be incredibly powerful,” he said. “Often, people don’t buy the first time they land on your site, so you’re going to have to market to them again. Sending a retargeted offer a week or even a month later can spur them to come back.”
