One of the worst niches for PPV (pay-per-view) ads is high-end B2B software or enterprise services. These products typically have long sales cycles, require in-depth demos, and target very specific decision-makers within companies. PPV traffic, on the other hand, is broad, low-intent, and interruption-based, making it poorly suited for such a focused and informed audience. You're essentially paying for impressions from users who have little to no interest or authority to make high-level purchasing decisions. The mismatch between the traffic quality and the niche's requirements leads to extremely low ROI. In this case, more targeted, intent-based channels like LinkedIn ads or search engine marketing would yield far better results, making PPV a poor choice for enterprise-level or complex B2B niches.
