Google Display Network averages $0.64 CPC and $2.98 CPM. Meta Ads averages $0.94 CPC and $6.63 CPM. Analysis for Spain in 2026.
Spain is a value market relative to other Western European economies — digital ad CPMs run roughly 15% below US baselines, reflecting lower disposable income per capita and a less concentrated advertiser base. Google and Meta dominate, with TikTok gaining share particularly quickly among Spanish under-30 audiences. The market is bifurcated linguistically and regionally: Catalan-language creative is meaningful in Catalonia, and a significant portion of Spanish ad budget actually targets Latin America from Madrid-based teams. Mobile-first behavior is more pronounced here than most European peers — Spain has one of Europe's highest smartphone penetration rates and mobile commerce shares. AEPD enforcement of GDPR is steady but less aggressive than CNIL or ICO.

The auction, the creative, the budget floor — the three things you actually need to know before picking a platform.
GDN buys impressions across 2M+ publisher sites via a real-time auction. You can bid CPC or CPM depending on the campaign goal. CPCs are 4–7x lower than search, but conversion rates are also lower — it's a top-of-funnel channel, not a decision-point channel.
Responsive Display Ads: 15 images (1200×628 landscape, 1200×1200 square, 1200×1500 portrait), 5 logos, 5 short headlines (30ch), 5 long headlines (90ch), 5 descriptions (90ch). Google auto-assembles.
$30–75/day gets a display campaign to statistical signal, though retargeting audiences reach signal faster and are the recommended entry point for smaller budgets.
Meta (Facebook + Instagram) runs an auction across Feed, Stories, Reels, Marketplace, and Audience Network. You optimize for a conversion event; Meta's algorithm decides bid and placement. Effective CPM is $6–12, effective CPC $0.80–1.50 depending on optimization goal and vertical.
Feed: 1:1 (1080×1080), 4:5 portrait (1080×1350). Reels/Stories: 9:16 (1080×1920). Video 15–60s. Carousel supports 10 cards. Copy ~125 chars before the truncate. Creative fatigue is the #1 cost driver — refresh every 2–3 weeks.
The algorithm needs ~50 conversion events per week per ad set to exit learning phase. For a $30 CPA that's ~$1,500/week or $6K/month per campaign. Below that, performance is a lottery.
