How to Choose an Influencer Marketing Agency in Greece (2026)

If you're searching for an influencer marketing agency in Greece, you'll find several options — but quality, structure, and what they actually deliver vary considerably. Choosing the wrong partner can mean wasted budget, bad data, or campaigns that don't perform.

This guide covers the criteria that matter, the red flags to recognize, and the questions you should ask every agency before deciding. It's written by Mavericks — we are an agency, so you'll get our perspective — but the framework applies to evaluating any partner.

Criterion 1: Roster exclusivity and quality

The most critical question: do the creators the agency proposes have exclusive representation, or are they on the lists of multiple agencies simultaneously?

Why it matters. Exclusive representation means the agency genuinely knows the creator, has direct access for negotiation, and can guarantee availability and terms. An open-network agency — that "works with thousands of creators" without exclusive deals — gives you access to creators you could reach yourself with a simple Instagram DM.

What to ask: "Which creators are exclusive with you? Can I see their profiles and historical engagement rates?"

At Mavericks we represent 27 creators on an exclusive basis — from PanosDent (2.5M followers) to gaming, lifestyle, and sports creators you won't find elsewhere. You can see the full roster before speaking to us.

Criterion 2: Case studies with real numbers

Every agency has impressive claims on their website. What actually reveals something is case studies — and specifically, whether they contain numbers or are just storytelling.

What to look for in a useful case study:

• What was the campaign objective (awareness / consideration / conversion)?
• Which creators were used and on which platforms?
• The core metrics: reach, engagements, engagement rate, CPE or CPA.
• Whether there were learnings or adjustments mid-campaign — shows process maturity.

Red flag: case studies with no numbers, no mention of metrics, or only reach figures without engagement data. Reach without engagement doesn't tell you whether anyone heard the message.

What to ask: "Can you show me a case study from a campaign similar to what I want to do, with numerical results?"

Criterion 3: Reporting and metrics

A serious agency gives you a structured post-campaign report — not screenshots from a creator's phone. Before signing, find out exactly what you'll receive after the campaign ends.

What a reliable campaign report should include:

• Reach and impressions per creator and per platform.
• Engagement (likes/comments/saves) and engagement rate.
• CPE (Cost Per Engagement) based on total budget.
• Top-performing content — what worked best.
• Audience insights where available (age, gender, location of engaged users).
• Recommendations for next campaign.

What to ask: "Can you show me an example campaign report? How do you verify the statistics from creators?"

Criterion 4: Pricing transparency

Influencer marketing pricing can hide surprises if you don't ask. A transparent agency tells you upfront:

• Creator fees: what goes to the creator.
• Agency management fee: what the agency retains for strategy, coordination, reporting.
• Usage rights: if you want paid media usage, this is billed separately.
• Exclusivity costs: if you want creator exclusivity, that has its own cost line.

Red flag: "We can't give prices without speaking first" — with no indicative ranges at all. An agency experienced in the Greek market can give you ranges without hearing your brand first.

Criterion 5: Legal and compliance

A serious agency handles the legal framework on your behalf — it doesn't leave it to the brand to sort out.

What the agency should cover:

• Written contracts with every creator covering deliverables, usage rights, exclusivity, and payment terms.
• Compliance with EU ad disclosure law — every post must carry proper disclosure.
• Tax documentation (creators on the roster issue proper invoices).

What to ask: "Who handles contracts with creators? Do you ensure ad disclosure on every post? What happens if a creator doesn't deliver?"

Red flags: what to avoid

The most common signs that an agency isn't the right partner:

• Promising "guaranteed results" without defining them. What result? On which metric? There are no guaranteed outcomes in influencer marketing — anyone who says otherwise either doesn't know or isn't being honest.
• Roster that changes per pitch. If they present different creators every time you speak, they don't have real exclusive relationships — they just have access to an open pool.
• No approval and revision process. If there's no structured approval workflow, you'll end up in endless email chains with content that doesn't match the brief.
• Creators with inflated followers. Request engagement rate data and check whether the follower-to-engagement ratio is healthy. Followers without engagement may indicate inorganic growth.
• Reporting only via screenshots. An agency with a mature process can verify stats — either via native platform analytics sharing or third-party tools.

Questions you must ask

In every agency briefing, ask these 8 questions:

1. Which creators are exclusive with you and which are non-exclusive network?
2. Can you show me a case study similar to what I want, with numbers?
3. What does the campaign report I'll receive include?
4. How do you verify statistics from creators?
5. What is the pricing structure — creator fee vs. agency fee vs. extras?
6. Who handles contracts and ad disclosure?
7. What happens if a creator doesn't deliver or delivers out-of-spec content?
8. Have you worked with brands in my category? What worked?

The answers to these questions will tell you whether the agency has a mature process or just good website pages.
