Did you know that over 70% of brands already consider influencer marketing a key acquisition channel? In fact, according to a study by Influencer Marketing Hub The investment in this channel continues to grow year after year.

The interesting thing is that, in 2026, it will no longer be enough to “try your luck” by sending direct messages. The ecosystem has matured, and tools like Meta's Creator Marketplace are marking a before and after.

If you work for a company or are part of a marketing agency in Barcelona, this is highly relevant to you. The difference between campaigns that work and campaigns that burn through budget usually lies in three things: strategic management, actual measurement, and the ability to scale.

From the agency, we see it constantly. Working with local brands and projects like Karmina, there's a pretty clear pattern: when the process is organised, results follow. When it's not, everything stays as loose actions.

In this article, we explain how the Creator Marketplace works, why it's key, and, above all, how to make the most of it without falling into the most common mistakes.

What is the Creator Marketplace and why is it key?

The Creator Marketplace is a feature built into Meta Business Suite that allows brands to connect with creators in a much more structured way.

Key functionalities

Allows:

• Find like-minded creators based on audience and interests
• Manage campaigns from a single environment
• Access verified real data (not screenshots)
• Enable collaborations with full traceability

This represents a significant change. We are moving from decisions based on intuition to a much more data- and performance-driven approach.

In fact, the very Meta explain this evolution towards more measurable collaborations in their official documentation.

From improvisation to system

A few years ago, many brands managed influencers the way one organises a last-minute dinner party: quickly, without much planning, and hoping everything would turn out alright.

The reality is that doesn't work anymore.

The Creator Marketplace makes influencer marketing much more serious: a measurable, repeatable, and scalable process.

In other words, it stops being fuzzy branding and becomes a real performance channel.

Why is it relevant for businesses in Barcelona?

Barcelona is a very active digital ecosystem. Startups, e-commerce, personal brands... they all compete for the same attention.

Advantages in local markets

This is where the Creator Marketplace adds value:

• Allows segmentation by location, ideal for local businesses
• Makes it easy to find micro-creators with real communities
• Help adapt campaigns to very specific audiences

This makes quite a difference, particularly in sectors like hospitality, retail, or local services.

The role of agencies

From an agency like ours, we see it clearly: the tool doesn't replace the strategy, but it does multiply it.

For example, we have combined in several projects:

• SEO strategy
• Creator campaigns
• Amplification through advertising

The result: more organised, more measurable and, above all, more profitable campaigns.

Case study

A client in the wellness sector in Barcelona moved from collaborating with influencers haphazardly to structuring campaigns with local micro-creators.

In three months, we saw:

• +38% in conversions
• Reduced cost per acquisition
• And something key: reusable content for campaigns

Nothing revolutionary. Simply doing things methodically.

Here's how the Creator Marketplace works, step by step: 1. **Businesses Search for Creators:** Companies looking to promote their products or services can browse the Creator Marketplace to find influencers and content creators who align with their brand and target audience. They can filter by niche, audience demographics, engagement rates, and more. 2. **Businesses Initiate Contact & Propose Campaigns:** Once a business finds a suitable creator, they can reach out through the platform. They'll typically propose a campaign, outlining their requirements, objectives, deliverables (e.g., type of content, number of posts, usage rights), and the budget they're willing to offer. 3. **Creators Review Pitches & Negotiate:** Creators receive campaign proposals from businesses. They can review the details, assess if the campaign fits their brand and audience, and decide whether to accept, reject, or negotiate terms (like the price, content specifics, or deadlines). 4. **Campaign Agreement:** If both parties agree on the terms, they formalise an agreement within the platform. This document often includes specifics about the content, posting schedule, payment terms, and any usage rights for the created content. 5. **Content Creation & Submission:** The creator then produces the content as agreed. This might involve photos, videos, blog posts, or social media updates. They'll typically submit the content for the business's approval before it goes live. 6. **Content Review & Approval:** The business reviews the created content to ensure it meets the agreed-upon brief and quality standards. They can provide feedback and request revisions if necessary. Once satisfied, they approve the content. 7. **Content Deployment:** After approval, the creator publishes the content on their chosen platforms according to the campaign schedule. 8. **Payment Processing:** Once the content is live and the terms of the agreement have been met, the business releases the payment to the creator, often through the Creator Marketplace's secure payment system. 9. **Reporting & Analytics (Optional but common):** Some platforms or campaign agreements will require creators to provide basic performance analytics or reports on the campaign's reach and engagement, helping businesses measure the effectiveness of their influencer marketing efforts.

Although it may seem complex at first, it actually follows a fairly logical flow.

Campaign creation

Definitions

• Content type (reels, stories, posts...)
• Budget
• Dates
• Goal of the collaboration

This is where many brands fail. If the objective isn't clear, everything else falters.

2. Creator Search

You can:

• Filter by audience
• Search by interests
• Invite specific profiles

And here's an important point: the biggest creator isn't always the best. In fact, micro-creators often perform better in terms of engagement and conversion, something that also highlights HubSpot in several of their analyses

3. Project Management

Everything happens within the platform.

• Messages
• Conditions
• Deliverables

This avoids the typical chaos of lost emails, WhatsApps, and files.

4. Publication and amplification

The creator posts with a paid collaboration tag.

You can then activate:

• Partnership Ads
• Content reuse

This is where many brands really cash in: using that content as a basis for campaigns.

Advantages, costs, and common errors

Not everything is perfect. But understanding this well saves you quite a bit of money.

How much does it cost?

The tool is free within Meta.

But there are associated costs:

• Pay the creator
• Advertising investment
• Management (internal or external)

There's no standard commission, and that's already a plus point compared to other marketplaces.

Main advantages

• Centralisation of the process
• Best selection of creators
• Scalability of campaigns
• Access to reliable metrics

Common mistakes

This is where we see the most failures:

• Failure to define strategy
• Unclear briefings
• Do not control advertising permissions
• Not labelling correctly

I remember a client who launched several collaborations without a clear brief. Result: nice content, but useless for ads. Money wasted.

How to use it well

• Clear content packs
• Prioritise micro-creators.
• Reuse content in campaigns
• Set up an approval system

Furthermore, tools like Notion, Slack, or CRM integrations help a lot in professionalising all of this.

Trend 2026: content + performance

Here's the important change. Influencer marketing is no longer just about visibility.

The new approach

It is now used as:

• User-generated content factory
• Ad engine
• Acquisition channel

According to Statista, the global influencer marketing market will exceed $30 billion in 2026.

What we see in practice

In projects like Karmina or collaborations with spaces like Utopic, the pattern repeats:

• Authentic content
• Amplification with ads
• Continuous optimisation

This turns every collaboration into an investment, not an expense.

Conclusion

The Creator Marketplace isn't just another tool. It's a way to organise and professionalise influencer marketing at a time when every euro counts.

If you're in Barcelona and want to stop doing one-off actions to start building something scalable, now's the time.
