What does a Facebook Ads agency do?

A specialized Facebook Ads agency takes over all phases of campaign implementation:

• Strategy & target definition – funnel structure (awareness, consideration, conversion), budget allocation, KPI definition
• Target group setup – custom audiences, lookalike audiences, interest targeting, remarketing lists
• Creative production – ad texts, image and video creatives, A/B variants for conversion testing
• Campaign management – daily optimization, budget control, bid strategy, placement testing
• Reporting & attribution – ROAS tracking, multi-touch attribution, monthly performance reviews

Facebook Ads vs. Google Ads: Which channel for which target?

Both channels are justified – but have different strengths:

The best strategy uses both channels: Google Ads actively catches searchers, Meta Ads builds brand awareness and reactivates prospects.

Meta Advantage+: AI campaigns as a game changer

2026 has developed Meta Advantage+ into a fully-fledged AI campaign system. The algorithms take over targeting, placement and bid optimization automatically – and in many cases beat manually optimized campaigns. What this means for advertisers:

• Less time for manual optimization – more time for strategy and creative
• Better performance through real-time optimization on millions of data points
• But: Creative quality is becoming even more important. Weak creatives will not be saved by AI

Social Media One manages Facebook and Instagram campaigns for brands such as Balenciaga, Schwarzkopf, Toyota and Purelei. ROAS optimization is our core competence – with demonstrable results.

Facebook Ads costs: what you should realistically budget for

The agency costs and the advertising budget must be planned separately:

• Minimum media budget: 1,500-2,500 EUR/month for measurable results. Below that, the data set is not sufficient for meaningful AI optimization.
• Agency fee: 1,000-3,500 EUR/month for setup, management and reporting, depending on campaign volume.
• CPM benchmarks Germany: 5-18 EUR CPM for standard target groups. Video ads: 3-10 EUR CPM. Retargeting: 10-30 EUR CPM (small audience = higher CPM).

Frequently asked questions about Facebook Ads

How much budget do I need for Facebook Ads?
At least 1,500 EUR/month media budget to provide sufficient data for algorithm optimization. Below 500 EUR/month, the ROAS remains unsatisfactory.

How long does it take for Facebook Ads to become profitable?
The learning phase of the algorithm takes 7-14 days (approx. 50 conversions). Full optimization: 4-8 weeks. Patience in the start-up phase is rewarded.

Do I need a Facebook Business Manager?
Yes – mandatory. The Business Manager separates private accounts from company assets and is a prerequisite for professional ad management.

What is ROAS and what is a good value?
ROAS = Return on Ad Spend. With an ad budget of EUR 1,000 and sales of EUR 4,000 = ROAS 4.0. Profitable e-commerce from ROAS 3.0-4.0. B2B: ROAS logic is less effective, CPL (cost per lead) instead.
