Facebook Ads vs Google Ads: How to Choose the Right Platform

Intent vs. discovery

Google Ads captures existing demand: the user is actively searching for a solution and you appear when they're ready to buy. Meta Ads creates demand: the user didn't know they wanted your product until they saw it in their feed.

If someone searches for an emergency plumber in Bucharest, Google wins without question. If you sell a lifestyle product people don't search by name, Meta delivers lower cost per acquisition and higher volume.

Business model matters more than platform

eCommerce with thin margins: Meta Ads (high volume, low CPC). B2B with long sales cycles: Google Ads plus LinkedIn. Local services: Google Ads. Mobile apps: Meta Ads or both. New brand: Meta for awareness, Google for direct conversions.

There is no universal rule — only your specific business model and the actual behaviour of your customers.

Minimum budgets and realistic expectations

For Google Search Ads, the useful minimum is €200–300/month in competitive niches (legal, real estate, medical services). Below that, campaigns lack the data needed for optimisation. For Meta Ads, you can get first data from €100–150/month, but €300+ is the threshold where you have enough volume for creative testing.

Average Google Search CPC varies widely: €0.10–0.20 in low-competition niches, €1–3 in real estate or financial services. On Meta Ads, average CPM in Romania is €3–8, with significant variation by audience and calendar period.

What creative do you need on each platform

Google Search runs on text. Investment goes into copy, keywords and ad extensions, not design. A strong Search ad has a title relevant to the query, a clear benefit and an explicit CTA.

Meta Ads is a visual platform. You need images or videos that stop the scroll in the first 2–3 seconds. Creative quality drives 70% of Meta campaign performance. If you lack visual production capacity, scaling Meta will be difficult.

How to measure results correctly

The common mistake is comparing ROAS in isolation per platform. A customer who saw a Meta ad and then purchased after a Google search contributed to both. Without a clear attribution model you will undervalue Meta (which initiates demand) and overvalue Google (which captures it).

Set different conversion windows: 7-day click plus 1-day view for Meta, 30-day click for Google. Use Google Analytics 4 to see the complete customer path before conversion.

When to use both platforms together

The right strategy for many businesses is to run both with clear roles: Google for conversions from existing demand, Meta to build new audiences and fuel remarketing. You're not doubling costs — you're multiplying the effect.

Minimum condition: a total budget of at least €500–600/month split between both platforms. Below that, focus on one platform and optimise it well before expanding.

The platform doesn't decide success. Strategy, creative and tracking are the variables that actually matter.

Why Platform Choice Is More Complex Than a Checklist

You now understand the logic behind each platform. The problem is that in practice the criteria overlap, data is incomplete early on, and the right decision only becomes clear after spending several months testing. Your customers' real behavior doesn't always match the theoretical model you chose.

Choosing the wrong platform doesn't necessarily mean no conversions. It means you pay 2–3 times more than necessary, or that scaling becomes impossible due to an audience ceiling. These problems aren't visible in the first month. They become obvious at 3–4 months of running.
