Digital marketing agency fees: how agencies price their work

How do digital marketing agencies set their fees?

Digital marketing agency fees depend on how many channels are managed, the ad budget, creative workload, reporting depth and store-side work. Agencies usually charge a fixed monthly retainer, a percentage of ad spend, a hybrid of both or a performance share. Your ad budget is separate from the fee and goes straight to the platforms.

This is an inside view from a digital marketing agency that works with ecommerce brands. We found no credible public benchmark for agency prices in Türkiye, so we will not quote a market range. Instead, here is how each model behaves and how to compare quotes fairly.

What is the difference between ad spend and the agency fee?

This gets blurred most often in first calls. Ad spend, or media spend, is the money you pay Google, Meta or TikTok. In a healthy setup it runs through ad accounts opened in your name, on your card or invoiced to your company. Google Ads accounts billed by Google Turkey are charged VAT at the Turkish standard rate, so the platform invoice already carries its own tax.

The agency fee pays for the people who build, run, test and report on those accounts. Seeing the two on separate invoices is the simplest way to check that your budget actually reached the platforms. A single "package price" that merges media and management makes it hard to tell how much went into ads.

Which pricing models do agencies use?

Quotes vary a lot, but most of them sit on one of a handful of models.

Model	How it works	Upside	Downside	Best fit
Fixed monthly retainer	Same amount each month for a defined scope	Predictable, no incentive to push spend	Needs renegotiation when scope grows	Clear scope, budget that moves around
Percentage of ad spend	A share of monthly media spend	Fee scales with the workload	Agency earns more when you spend more	Steadily growing accounts with many campaigns
Hybrid	Base fee plus a spend percentage or performance bonus	Covers core labour, rewards growth	Harder to calculate	Mid-size brands planning fast growth
Performance or revenue share	Fee tied to sales, revenue or a target	Links the agency to outcomes	Attribution disputes, returns and discounts get messy	Brands with solid, transparent tracking
One-off project or audit	Fixed price for a defined piece of work	Clear start and end	No ongoing management, execution priced separately	Setup, tracking audits, account rebuilds

There is one useful reference point from the US. In the 2022 edition of the ANA's agency compensation study, which covers large American advertisers, a clear majority of respondents said they used fee-based models, and the share using performance incentives had dropped noticeably compared with a decade earlier. That does not describe ecommerce brands in Türkiye, but it does suggest performance pay is harder to run well than it looks on paper.

Why is performance pricing harder than it sounds?

"Only pay when sales come in" sounds attractive until the questions start. Are sales counted from the ad platform or the store backend? Are returns and cancellations deducted? Who gets credit for organic and repeat customers? How do you separate the effect of a sitewide discount? If the contract does not define these, month one ends with an argument about definitions instead of results.

What drives the price of an agency?

Two brands with the same budget can need very different amounts of work. The main drivers are:

• Number of channels: running Meta alone is a different job from running Google, Meta and TikTok together.
• Ad budget and campaign count: larger budgets mean more tests, more structure and more daily checks.
• Creative production: working with existing assets is not the same as producing new videos and images every month.
• Tracking and reporting: Pixel, Conversions API, a Merchant Center feed and reports reconciled with store data all take time.
• Platform work: product pages, landing pages and speed fixes on Shopify, ikas or Ticimax are usually priced separately.

How do the models behave as the budget grows?

Quotes built on different models can look close today. The real difference shows up when your ad budget grows.

Model	Agency fee as the budget grows	What to watch
Monthly retainer	Stays the same as long as the scope does	More spend usually means more work; the contract should say when the retainer is reviewed
Percentage of ad spend	Grows in step with the budget	The agency may lean toward higher spend; ask whether the rate steps down as you scale
Hybrid	Grows more slowly; the fixed part stays, the percentage part rises	Get the scope of the fixed and variable parts written down separately
Performance share	Rises or falls with sales or profit	Agree up front on the data source and how returns and cancellations are handled

The model that looks cheapest today can become the most expensive once spend doubles, and the reverse is also possible. When you ask for quotes, share your planned budget for the next six and twelve months, not just today's, and ask each agency to show in writing how its fee changes in those scenarios.

Which hidden costs should you check?

Most surprises come from what a quote leaves unsaid. Ask about each of these before you sign:

• Is creative production (video shoots, UGC, design) included or billed separately?
• Is there a setup or onboarding fee?
• Who pays for reporting dashboards, tracking tools and software licences?
• Are landing pages and store-side changes in scope?
• How does the fee change if you add a channel such as TikTok, Pinterest or marketplace ads?
• What is the minimum term and the notice period?
• Are prices quoted with or without VAT?

How do you compare agency quotes?

Totals mean little if the scopes differ. Work through it in this order:

1. Put both scopes in one table. List channels, campaign count, creative volume and reporting frequency side by side.
2. Separate media spend. Make sure the agency fee is a clear number, independent of ad spend.
3. Model the growth scenario. Ask what each fee becomes when your budget doubles.
4. Find out who runs the account. Is the person on the sales call the one doing the daily work, and how experienced are they?
5. Ask for a 90-day plan. A tracking audit, account structure review and test plan should be written down.
6. Read the contract and exit terms. Notice period, access handover and ownership of creative files should all be clear.

For a wider checklist on choosing a partner, the questions in our guide to choosing an ecommerce marketing agency pair well with this comparison.

What are the red flags?

• Guaranteed ROAS or revenue. A firm number given before anyone has seen your account, margins and tracking is a sales line, not a plan.
• A vague contract. A one-line scope such as "digital marketing services" sets you up for every task to become an extra.
• Ad accounts opened in the agency's name. Google Ads and Meta both let you grant an agency access to your own accounts at a chosen level. Accounts, Pixel and Merchant Center should belong to you, so you keep your history if the agency leaves.
• Media billed through the agency without a breakdown. Without platform invoices, you cannot know how much reached the ads.
• Long lock-ins with a hard exit. Contracts without a reasonable notice period deserve a second look.

How does Performetic share its pricing?

Performetic does not publish a price list, because the fee depends on channels, budget and how wide the scope is. We start with a free growth audit: we review your ad accounts, tracking and store and report the priority growth opportunities we find. After that, we share the quote in writing together with the scope. You can see what the work covers on our performance marketing service page.

If you want the scope worked out for your own account, request a free growth audit and we will send the findings and the quote in writing.

Key takeaways

• Ad spend goes to the platforms and the fee goes to the agency; keep them on separate invoices.
• Retainers buy predictability, percentage of spend scales with the work, hybrids balance both and performance deals need solid tracking.
• Channels, budget, creative, tracking and store work drive the fee.
• Model every quote against your planned growth, not just today's budget.
• Guaranteed ROAS, vague scope and agency-owned ad accounts are red flags.
