Content recommendation engine Taboola has acquired Perfect Market, which develops a publisher-side solution designed to improve engagement, driving traffic, and monetization. Taboola CEO Adam Singolda wouldn’t disclose the deal’s terms, though he said it was a mix of cash and stock. With the acquisition, Taboola will change from being a content discovery engine to being a content and product discovery engine. “We work with thousands of publishers, and the industry is looking for more innovation around monetization across the board,” said Singolda. Taboola will answer those publisher concerns by integrating Perfect Market’s monetization product, Perfect Ads, into the Taboola platform. The technology will power Taboola-X, Taboola’s first programmatic ad solution, which will serve both the buy and sell sides.
