Looking at how people set up LinkedIn audiences for mid-market B2B tests, the usual instinct is to target exact job titles like "Head of Operations" because it looks precise. But titles are messy. One company calls the role VP Ops, another calls the same job Director of Business Excellence, and title matching misses a lot of the people you actually want.
Job function plus seniority catches more of the right people, at the cost of some noise. On a small budget I'd lean that way, then cut the noise down with a matched company list. Exact titles only make sense when you know your buyer's title is unusual.
Has anyone seen tight titles beat broader filters on pipeline, not just CTR?
