MSN, Microsoft’s web portal and collection of services and apps, said on Tuesday it has signed a deal with Taboola, a nine-year-old company best known for supplying content recommendations tools for publishers.

No terms were disclosed, but the companies said that Taboola’s integration into MSN’s websites will reach a total of 50 markets, and be available in 24 languages. Taboola’s content recommendation services were already integrated into MSN sites in 28 market and nine languages, according to the announcement.

Taboola’s recommendations from publishers and advertisers will appear on the MSN.com homepage, as well as in individual articles, according to Business Insider. MSN’s editors will also start using Taboola’s tool for newsrooms, which lets them live-test different content, designs, and placement to different sets of users to see which variations perform best.

The deal is one of the largest for Taboola, and will likely help it expand its reach, which in turn only strengthens its attractiveness to future partners and customers. According to a report from comScore Media Metrix in November, MSN reaches more than 397 million unique visitors every month, Microsoft MSFT said.

This deal is also in line with the MSN’s shift in strategy since 2014, as Business Insider notes. Previously staffed with news reporters who produced original content, but following a MSN-wide redesign, which included newly-rebranded apps, it shifted to curating news and content from other major media companies. It has outsourced other functions to outside partners as well.
