Northwell Health has 202 ads in the Meta Ad Library, and 172 were running when we read it on September 23, 2026. Below is a page of that creative, the formats it uses, and how long the ads stay up.
The creative read here is 37 percent video, 37 percent single image, 27 percent carousel. The median ad ran 44 days and the longest was still up at 256. 85 percent of everything Northwell Health has published on Meta is still delivering, which is a brand running breadth rather than retiring losers.
