Facebook Ads vs Google Ads: Which Is Better?

This is the fundamental difference. Facebook Ads show your product to people who might be interested based on their behavior and profile — even if they've never searched for it. You're creating demand. Google Search Ads appear when someone actively types a query like 'best running shoes' — they already want something. You're capturing existing demand.

This matters for strategy: if nobody is searching for your product (new category, novel product), Facebook is your primary channel. If there's high search volume for what you sell, Google captures that intent at the moment of highest purchase readiness.

On Facebook, your ad creative is effectively your targeting mechanism. As Meta's algorithm has moved toward broad targeting and Advantage+, the creative itself determines who sees and engages with your ads. A video showing a kitchen gadget in action will naturally reach people interested in cooking — the algorithm learns from engagement signals.

On Google Search, creative matters less because the keyword does the targeting work. Your ad copy needs to be compelling, but the match between search query and ad determines relevance. Google Shopping relies more on product images and pricing than creative storytelling.

Facebook Ads are generally cheaper on a CPM basis ($5-$15 for ecommerce), but you're paying to reach people who may not be ready to buy. Conversion rates are lower because you're interrupting, not answering a question.

Google Search is more expensive per click ($1-$4+), but click-through often signals high intent. Conversion rates for Search campaigns are typically higher because the user is already in buying mode. The cost-per-acquisition math can favor either platform depending on your product and margins.

Google Ads benefits from clearer attribution — someone searches, clicks, buys. The path is direct and trackable. Facebook Ads attribution has been more challenging since iOS 14.5, which limited pixel tracking. View-through conversions, multi-touch attribution, and platform discrepancies make Facebook ROAS harder to measure accurately.

This is why creative analytics matters more for Facebook — when attribution is fuzzy, understanding which creative elements drive engagement becomes the primary optimization lever.
