The core difference: intent vs interruption
Understanding Google Ads vs Meta Ads starts with one fundamental question: does your customer know they need you?
Google Ads captures people who are already searching for what you sell. Someone types "dentist Barcelona" — they need a dentist right now. Meta Ads (Facebook and Instagram) interrupts people who aren't searching for anything — but who match the profile of your ideal customer.
Google Ads = demand capture. Meta Ads = demand creation. Most businesses need both — but which to start with depends on your situation.
Google Ads: when search intent wins
Google Ads works best when:
- People actively search for your product or service ("plumber Madrid", "lawyer Spain")
- Your average transaction value is high (€500+) — higher intent = worth paying more per click
- You sell something people need urgently (medical, legal, repairs)
- You want leads, calls, or appointments — not brand awareness
The downside: Google Ads in Spain are expensive. Average CPC (cost per click) ranges from €0.80 for e-commerce keywords to €8–15 for legal and medical terms. You're competing with companies who have been optimizing for years.
Meta Ads: when audience targeting wins
Meta Ads work best when:
- You can define your customer profile precisely (age, interests, income, behavior)
- Your product is visual — fashion, food, furniture, beauty
- You sell online (e-commerce) and can retarget website visitors
- Your average order value is under €200 and you need volume
- You want to build brand awareness in a specific geographic market
Meta Ads in Spain have lower average CPCs (€0.30–1.20) but lower purchase intent. You're paying less per click but those clicks are less ready to buy.

| B2B services | 3.9× | 1.5× |
Should you run both?
For most businesses with a budget of €1,000+/month: yes. Here's why:
- Google Ads captures people ready to buy now (high-intent)
- Meta Ads builds awareness so those people already know your brand when they search
- Meta retargeting of your Google Ads website visitors is extremely effective
- The combination consistently outperforms either channel alone by 40–60%
Start with Google Ads if your budget is €500–1,000/month (focus on one channel). Add Meta Ads when budget reaches €1,000+/month. For e-commerce with visual products, start with Meta.
Bottom line
There's no universal winner. The right platform depends on your industry, budget, customer profile, and whether you're selling to people who are already looking for you or to people who don't know they need you yet. Most mature businesses need both, but the right starting point and budget split depends on your specific situation — which is exactly what we cover in the free audit.
La diferencia fundamental: intención vs interrupción
Google Ads captura personas que ya buscan lo que vendes. Meta Ads interrumpe a personas que no buscan nada — pero que coinciden con el perfil de tu cliente ideal.
Google Ads = captura de demanda. Meta Ads = creación de demanda. La mayoría de negocios necesitan ambos — pero con cuál empezar depende de tu situación.
Comparación de costes en España (2026)
| Métrica | Google Ads | Meta Ads |
|---|---|---|
| CPC medio (general) | €1,50–3,00 | €0,30–0,80 |

| Tasa de conversión típica | 3–8% | 1–3% |
| Presupuesto mínimo efectivo | €500/mes | €300/mes |
¿Deberías usar ambas?
Para la mayoría de negocios con presupuesto €1.000+/mes: sí. Google Ads captura a quien está listo para comprar ahora. Meta Ads construye el conocimiento de marca para que te conozcan cuando busquen.
Фундаментальна різниця: намірність vs переривання
Google Ads захоплює людей які вже шукають те що ти продаєш. Meta Ads перериває людей що нічого не шукають — але відповідають профілю твого ідеального клієнта.
Google Ads = захоплення попиту. Meta Ads = створення попиту. Більшість бізнесів потребують обох — але з чого почати залежить від ситуації.
Порівняння витрат в Іспанії (2026)

Чи варто запускати обидва?
Для більшості бізнесів з бюджетом €1,000+/місяць: так. Google Ads захоплює тих хто готовий купити зараз. Meta Ads будує впізнаваність бренду щоб тебе знали коли шукатимуть.
