Search ads catch people who already know they need a category of software. The trouble is that many products create their own category, or sell into a problem the buyer has not named yet. Nobody types the phrase for a workflow they have never imagined. LinkedIn works the other way around: you choose who sees the message by job function, seniority, industry and company size, and you meet them while they are reading about their own work.
That fits how software is bought. A mid-market deal can involve a champion who uses the product daily, a manager who owns the problem, an IT admin who worries about single sign-on and a finance lead who reviews the renewal terms. Each of them needs a different reason to care. On LinkedIn you can run those conversations in parallel inside the same set of target accounts.
Where the platform lets SaaS teams down
The feed is also where many software marketers lose patience. Clicks are pricier than on consumer channels, form fills from students and job seekers creep in, and a lead gen form can look busy while the sales team calls numbers that never answer. The cause is usually setup, not the channel: audiences drawn too wide, a single offer for every role, and conversion tracking that stops at the thank you page.
