In short
Google Ads wins when buyers already know they have a problem and are searching for a solution (high intent, lower volume). Meta Ads wins when you need to create demand and reach buyers at scale (lower intent, higher volume). Most successful brands run both — Google to close in-market demand, Meta to fill the funnel.
The core difference: intent vs reach
Google Ads intercepts demand that already exists — someone is actively searching for what you sell. Meta Ads (Facebook and Instagram) creates demand by putting your offer in front of people who fit your audience but weren't searching today. Neither is universally better; they solve different problems.
When Google Ads is the right starting point
Choose Google first when your buyers actively search for your service, when the sales cycle is short, or when you need predictable lead flow inside 30 days. Local service businesses, urgent B2B services, and brands with proven keyword demand almost always start here.
- Plumbers, dentists, lawyers, electricians — anything urgent and local
- B2B SaaS targeting bottom-funnel keywords (alternatives, comparison, pricing)
- Ecommerce with a clear search demand for the product category
- Brands needing predictable lead flow in 30–60 days
When Meta Ads is the right starting point
Choose Meta first when your category doesn't have strong search demand, when your product is visual, when you sell to a clear demographic or interest segment, or when your offer is irresistible enough to interrupt someone's feed.
- DTC ecommerce with strong creative
- Lifestyle and consumer brands
- Coaching, courses, info products
- Local service brands warming a cold audience before a Google retargeting layer
The combined model most brands should run
Once you're above $5K–$10K monthly spend, run both. Google captures the high-intent buyers searching today. Meta fills the funnel with new audiences and retargets your Google visitors. The two compound: Meta lifts your branded search, branded search converts on Google, and your blended CPL drops.
What to measure (and what to ignore)
Cost per click is a vanity metric. Cost per qualified lead, cost per qualified meeting and pipeline value are what matter. Wire offline conversion uploads from your CRM into both platforms so the algorithms optimise toward revenue, not form fills.
Common mistakes that waste budget on both platforms
On Google: broad-match without a strong negative list, Performance Max without offline conversions, optimising on form fills instead of qualified meetings. On Meta: tiny budgets spread across too many creatives, no offer differentiation, ignoring creative as the primary lever. Fix these before adding spend.
