Are Tech Giants’ AI Ad Tools Killing Agencies?
Introduction: Agencies Under Pressure
For years, agencies managed ad campaigns for clients. But now, Google and Meta’s AI ad platforms are making agencies look redundant.
These tools automatically:
-
Create ads
-
Pick targeting
-
Optimize bids
-
Scale campaigns
So why should clients pay agencies thousands when AI can do it in minutes?
