The Facebook-versus-Google debate has a boring, profitable answer: they do different jobs. Understanding the difference stops you from burning budget on the wrong one.
1. Intent is the dividing line
Google catches people searching for a solution now; Facebook creates desire people did not have yet.
2. Facebook wins discovery
New fashion brands, food and gadgets thrive on scroll-stopping creative.
3. Google wins urgent services
"AC repair Dhaka" is a Google search, never a Facebook scroll.
4. Costs behave differently
Facebook sells impressions cheaply; Google charges premium for high-intent clicks that convert better.
5. Creative burden differs
Facebook demands fresh images and video weekly; Google demands tight keywords and landing pages.
6. Retargeting stitches them together
Catch the Google visitor who did not buy with a Facebook reminder ad.
7. The 70/30 starting split
Skew toward Google if people search for your category, toward Facebook if you must create the demand.
Run both small for a month, measure cost per actual sale (not per click), then feed the winner. The data will surprise you.
