If you're an e-commerce business owner looking to hire a PPC agency for the first time, the process can feel overwhelming. There are countless providers, the price ranges are enormous, and the promised services sound similar across the board.

What is PPC and what does a PPC agency cover?

PPC - often called SEA (Search Engine Advertising) in the German-speaking market - means paid ads in search engines. In practice, PPC in Europe almost exclusively means Google Ads with its various campaign types, occasionally supplemented by Microsoft Advertising.

A PPC agency takes over the strategic planning and operational execution of your search engine advertising. That typically covers keyword research, campaign structuring and steering, ad creation and optimisation, bid management, managing Shopping campaigns and the Merchant Center, Performance Max, Display and remarketing campaigns, plus ongoing tracking and reporting.

When does a PPC agency pay off for e-commerce?

Below €2,000 in monthly ad budget, professional agency management is often hard to justify economically. The agency fees become too high relative to the ad budget.

From €3,000 to €5,000 in monthly budget, an agency makes sense in most cases. The savings and improvements a good agency delivers typically exceed the agency costs by a clear margin.

Above €10,000 in monthly budget, having no agency - or a bad one - is almost always the most expensive scenario. The losses from poor campaign steering, messy tracking and missed optimisations quickly run into five figures per year.

Choosing the right PPC agency

The selection process is probably the most important decision you'll make in Google Ads. Start with a longlist of five to eight agencies. Look specifically for those that focus on e-commerce.

The first round of conversations isn't about detailed proposals - it's about getting a feel for how they work. Does the agency ask good questions? Are they genuinely interested in your business?

PPC agency costs and pricing

PPC agency prices vary widely. You'll find offers from €500 per month to over €10,000 per month.

For professional e-commerce management in the DACH region: a shop with €3,000 to €10,000 in monthly budget typically pays €500 to €2,000 in monthly agency fees. At €10,000 to €30,000 in budget, €1,200 to €3,500 is common. On top of that come one-off setup costs between €1,000 and €4,000.

The onboarding process

Onboarding determines how productive the partnership becomes in the first months. Good agencies have a structured process that runs over the first two to four weeks: a briefing call, access to all relevant systems, a technical audit, tracking verification, quick-win optimisations, and an action plan for the first three months.

The contract: what to look out for

The term should be limited - ideally a maximum of three to six months, then cancellable monthly or quarterly. The deliverables should be described concretely. Account access must be clearly regulated: the account runs in your name.

The first months: what's realistic

In the first one to two months, often nothing spectacular happens. The agency cleans up, fixes tracking, optimises core structures. From month three, the first clear improvements should be measurable. The real effect of a good partnership typically shows between months six and twelve.

Conclusion: the right PPC agency is a strategic decision

Hiring a PPC agency is a strategic decision for an e-commerce shop, not an operational purchase. Take your time with the selection, ask concrete questions and scrutinise proposals for substance.
