Honestly, depends on what you're asking it. If it's surface-level stuff like "what's a good bid strategy for a new campaign?" then sure, ChatGPT will spit out something that passes the sniff test. That's just pattern recognition from years of blog posts and forums.
But actual strategic thinking? hell no. Marketing strategists operate on proprietary data, client-specific context, and gut feel that comes from getting burned multiple times. We sign NDAs for a reason. ChatGPT doesn't have access to that, so its output reads like a student who crammed the textbook the night before and is now waffling through an answer. It's generic, safe, and lacks any real teeth.
the international marketing point is spot on too. saw someone in a thread asking for advice targeting South Asian audiences, and the AI served up generic "respect family values" nonsense that could apply to anyone. It's essentially a Western perspective pretending to be universal. The further you get from that WEIRD bubble-Western, Educated, Industrialised, Rich, Democratic-the more the advice falls apart.
for PPC? It's fine for explaining concepts or writing ad copy variations when you're brain dead. But for actual strategy, campaign structure, or audience insight? You'd be better off asking someone who's actually managed the accounts. ChatGPT isn't replacing that any time soon.
