Google Ads vs Facebook Ads: Which Should You Run First?

The fundamental difference

Google Ads is intent-driven. Someone types 'emergency plumber near me' — you show up, they call. The buyer has already decided they need the thing; you're just the one they find. Facebook Ads is interruption-driven. You show a compelling offer to a targeted audience that wasn't looking for you. You have to create the desire before you capture it.

That's why Google Ads produces leads faster for known needs (services, B2B, medical) and Facebook wins for discovery-led products (ecommerce, coaching, local dining, courses).

Targeting

• Google: intent-based (keywords), location, device, some audience layers.
• Facebook: interest, behavior, lookalike, custom audiences from your customer list — much richer if the offer benefits from persona targeting.

Creative demands

Google Ads leans heavily on text, keyword coverage and ad extensions. Creative production is manageable. Facebook lives or dies on creative — you need fresh video and image ads every few weeks, and the winning creative rarely comes from the first batch. A business without capacity for regular creative testing will struggle on Facebook.

Cost and CPL

Click costs are usually 3–10x higher on Google than Facebook, but CVR is usually higher too because intent is stronger. Blended CPL is often similar; the difference is in lead quality — Google leads tend to be closer to buying, Facebook leads need more nurturing.

Attribution and measurement

Google Ads reports are relatively reliable because clicks are trackable end-to-end. Facebook post-iOS 14 lost a lot of granular attribution — CVR looks worse than reality, and you now need offline conversion imports and modeled conversions to see the true picture.

When to start with Google

• Service business with immediate need (plumbing, legal, medical, HVAC).
• B2B lead-gen with defined search demand.
• Ecommerce with branded search or well-known category demand.
• Small creative capacity — text ads work.

When to start with Facebook / Meta

• Ecommerce with visual, discovery-led products.
• Info products, courses, coaching.
• Local businesses with strong brand imagery (restaurants, gyms, med spas).
• You already have great short-form video and creative in-house.

The real answer: both, sequenced

Start with the one that matches your offer's stage. Prove ROI. Then layer the second channel to expand demand — Google captures the intent Facebook created, Facebook retargets the browsers Google sent. Together they cost less per customer than either alone at scale.
