Why it works
Industry codes describe a company in broad strokes and often lag behind what it does today. The words in its job posts, such as the clients it serves or the products it handles, place it in a vertical more precisely. That lets you build a list for one niche that an industry filter would blur.
How to act on it
Build vertical SaaS, agency, consulting, or equipment prospect lists.
