A Facebook Ads agency in 2026 – what does it cost and how do you choose the right partner?

In 2026 the cost of working with a Facebook Ads agency in Poland starts at around PLN 1,500–2,500 net a month for small budgets, and with larger campaigns (e.g. e-commerce with budgets of PLN 20,000–50,000) can run to several or even a dozen thousand. Choosing the right partner should rest on an analysis of billing models, experience in your industry, transparent reporting and the approach to testing and optimisation. A good Facebook advertising agency does not just set up campaigns – it handles the whole process from strategy to results analysis.

What a Facebook Ads agency does – the full scope of the service

A professional Facebook Ads agency (also called a Meta Ads agency) handles the entire process of planning and running campaigns. That covers preparing the media strategy, setting up the ad account and the pixel/CAPI, and testing creatives and segmenting audiences.

The scope of work usually also covers integration with Instagram Ads, remarketing, cost optimisation (CPC, CPM, CPA) and performance reporting. In practice the agency takes on the whole process so the client can focus on sales and customer service.

Strategy, creatives, A/B tests, optimisation

A key element of the cooperation is a media strategy matched to the campaign's objectives: lead generation, e-commerce, brand awareness or remarketing. The agency prepares ad sets, tests different formats (static, video, collections, reels) and runs systematic A/B tests.

Optimisation means constantly analysing costs and results. Metrics such as CPC (cost per click), CPM (cost per 1,000 impressions), CPA (cost per acquisition) and ROAS (return on ad spend) are the foundation for judging the work.

Tracking and results reporting

Without solid tracking there is no way to judge a campaign's effectiveness. The agency implements the Meta Pixel or CAPI (Conversion API), configures events and conversion paths and makes sure the analytics work properly.

Reports should be transparent and contain not only campaign results but recommendations for the next stages. A professional Facebook advertising agency does not limit itself to sending a PDF once a month – it explains the results and suggests next steps.

How much does working with a Facebook Ads agency cost in 2026?

Costs in 2026 depend on the scale of the media budget, the billing model chosen and the scope of additional services (e.g. graphic creatives, photo shoots).

Billing models (retainer, %, hybrid)

1. A fixed monthly fee (retainer) – most often PLN 1,500–6,000 net, regardless of budget size.
2. A % of the ad budget – usually 8–15% of ad spend (e.g. with a PLN 30,000 budget the fee is PLN 3,000).
3. A hybrid model – a base (e.g. PLN 2,000) + a % of the budget (e.g. 10%). A popular solution with rapidly growing budgets.

How to choose an agency – criteria and the most common mistakes

• Experience in your industry – check whether the agency has worked for companies similar to yours.
• Case studies – ask for examples of campaigns with KPIs (e.g. ROAS 5, CPA PLN 45).

• Transparency – access to the ad account, Meta invoices issued to your company.
