Google Ads vs Meta Ads - how to actually choose

← Back to Field Notes

Google Ads and Meta Ads are fundamentally different platforms with different strengths. Google captures existing demand - people actively searching for what you offer. Meta creates demand - it puts your product in front of people who are not actively looking but might be interested. That distinction determines which platform makes more sense as a starting point for your specific business.

When Google Ads is the right first choice

If people search for your product or service category, start with Google. Plumbers, solicitors, accountants, IT support companies, insurance brokers, car dealers - all have users actively searching specific terms with high purchase intent. Google Ads captures that intent at the moment it exists. The conversion path is shorter and the CPA is typically lower than creating demand through social advertising for categories where intent is strong.

The test is simple: go to Google Keyword Planner and check the search volume for the main keywords describing what you sell. If there is meaningful monthly search volume with reasonable CPCs, Google is where you should start.

When Meta Ads is the right first choice

If your product or service is not something people typically search for - because it is new, novel, or in a category where awareness is low - Meta's interest and demographic targeting gives you a way to reach potential buyers who would not find you through search. Direct-to-consumer physical products, subscription services in emerging categories, and highly visual products often perform better on Meta initially because discovery happens through seeing rather than searching.

Meta is also generally better for building brand awareness at scale and for reaching very specific demographic or interest-defined audiences. If you know exactly who your customer is by age, interest, and life situation, Meta's targeting can find them efficiently.

Why the comparison is imperfect

Google and Meta measure conversions differently. Google's conversion tracking is click-based. Meta's includes view-through conversions - attributing conversions to users who saw an ad but did not click. This makes Meta's reported CPA look better than it often truly is. When comparing performance across platforms, make sure you are comparing on the same attribution methodology before drawing conclusions about which platform delivers better ROI.

Running both

Most mature businesses run both. Search captures existing intent. Social creates new awareness that feeds into search volume over time. The question is which to prioritise first with a limited budget. For businesses where intent-based search volume exists, Google first, Meta second. For businesses where awareness is the primary challenge, Meta first to build the audience, then Google to capture the branded searches that result from awareness activity.
