It's the most common question in paid marketing, and most answers are secretly "whichever one the agency prefers selling." The real answer hinges on a single distinction: demand capture versus demand creation.
Google Ads: capturing existing demand
Someone types "emergency plumber near me" or "best CA coaching in Kolkata" — they've already decided to buy; the only question is from whom. Google Search ads intercept that moment. Clicks cost more, but intent is sky-high: these are the cheapest customers (not clicks) most service businesses will ever buy.
Choose Google first if: people actively search for what you sell, your service is urgent or needs-based, or you're a local business where "near me" searches decide winners.
Facebook & Instagram Ads: creating demand
Nobody searches for a product they don't know exists. Meta ads interrupt the scroll with something desirable — which makes them the engine for D2C brands, visual products, offers and impulse-friendly price points. Clicks are cheap, but you're starting the conversation from zero, so creative quality decides everything.
Choose Meta first if: your product is visual, giftable or new to the market; your buyers are defined by lifestyle rather than search terms; or your price point supports impulse decisions.
The sequencing most businesses should follow
- Service businesses: Google Search first, then Meta remarketing to people who visited but didn't enquire.
- E-commerce: Meta prospecting first for scale, Google Shopping alongside to catch searchers, then remarketing across both.
- B2B: Google for high-intent keywords, LinkedIn where deal sizes justify it, Meta mostly for remarketing.
