TL;DR — Google Ads vs Facebook Ads in 30 seconds

If you’re selling a category buyers already search for, Google Ads wins on conversion rate and CAC. If you’re creating demand, building brand, or selling visually, Facebook Ads (Meta) wins on reach and creative leverage. Most brands above $50K/month in spend run both — Google Ads for the bottom of the funnel and Facebook Ads for awareness + retargeting. Our paid ads service page covers how we handle both.

The intent difference that decides everything

Google Ads vs Facebook Ads boils down to one structural difference: intent. A Google searcher is actively looking. A Facebook scroller is consuming content with no immediate purchase intent. That means Google Ads converts faster (often 3-7% on search) but caps at the volume of search demand. Facebook Ads converts slower (usually 0.8-2.5%) but reaches anyone matching the audience definition.

Attribution & iOS 14.5 four years later

Four years post iOS 14.5, both platforms have rebuilt their tracking via modeled conversions and server-side APIs. Meta CAPI and Google’s Enhanced Conversions recover most of the lost signal.

When to choose Google Ads, Facebook Ads, or both

Pick Google Ads when…

• You sell something buyers already search for.
• Your category has clear comparison and high-intent keywords.
• You have a strong landing page but limited creative production.
• B2B SaaS with named-account demand.

Pick Facebook Ads when…

• You create demand for a new category or product.
• Your offer is visually compelling (DTC, fashion, food, fitness).
• You can ship 30+ creatives per month.
• You’re building brand at low CPM.

Run both when…

• You spend over $50K/month and want a balanced funnel.
• You have measurable demand (search) and capacity for creative (social).
• You’re at the scale where retargeting from social to search creates real lift.
