Two platforms, two different jobs
Google Ads captures demand that already exists: someone searches, you appear. Meta Ads creates demand that does not exist yet: someone scrolls, you interrupt. Neither is better. The right first choice depends on whether people are already searching for what you sell.
When Google Ads should come first
If your category has search volume with buying intent, start with Google Ads. You are fishing where the fish already are, and results arrive in days. The constraint is volume: you can only capture as much demand as exists.
When Meta Ads should come first
If your product is visual, impulse-friendly or new to the market, start with Meta Ads. Restaurants, fashion, fitness and e-commerce brands can create desire with the right creative. The constraint is creative quality and testing velocity.
The honest answer for most businesses
Run Google first if search demand exists, then layer Meta for growth once cost per lead is stable. And make sure your website can convert the traffic either platform sends, or both budgets leak.
