What is an influence agency or influencer agency?
By definition, an influencer agency is agency that collaborates with influencers to promote a brand or company. In practice, the role of an agency specializing in influencer marketing covers a wide range of areas, from influencer recruitment and content creation to contract negotiation, strategy development, and data analysis.
What is influence?
At So Bang, as aninfluence agency, we define influence as the ability of a natural or legal person to mobilize an online community around a cause, a product, a service, an idea, etc.
Thus, influencermarketing is a particularly powerful lever for brands and companies that wish to increase their awareness (image, visibility) or their sales among consumers.
Today, online influence is primarily exerted through blogs and social media. Instagram, Facebook, Twitter, TikTok, YouTube, LinkedIn, and other platforms represent strategic territories for brands to express themselves. These territories can sometimes be hard-won due to fierce competition.
Definition of an influence agency
Based on what we have just discussed, we can define an influence agency as a company specializing in implementing communication strategies aimed at persuading, convincing, or inspiring various target audiences. This approach is achieved through different communication formats, leveraging the principles of persuasion and the influence of its influencers.
For purists, a distinction can also be made between an influencer marketing agency and an influencer communications agency, which works specifically with influencers to promote products or services. The influencer agency, on the other hand, relies on key messages and relevant content to exert a positive influence on its audience.
What is the role of an influence agency?
The role of an influence agency like So Bang is to support brands and companies on social networks to maximize profits in terms of image (ereputation) or sales (social selling).
In practical terms, the influencer agency will begin by identifying the right social media platforms and, above all, the best influencers to promote each brand according to its objectives and target audience. Once the best ambassadors have been identified, the agency will then contact them to formalize a collaboration.
The main missions of an influence agency
1. Definition of the influence strategy
An influencer agency starts by analyzing the brand's objectives : awareness, engagement, sales, branding… It then defines the platforms and formats : Instagram posts, product checks on YouTube, TikTok Ads, LinkedIn posts, etc.
2. Influencer Selection
The agency identifies the best influencers based on their audience, engagement rate, and credibility. It creates a comprehensive influencer map to optimize campaign performance.
3. Contractualization and relationship management
The agency formalizes partnerships between brands and influencers with clear contracts (obligations, rights to use content, remuneration, KPIs to track, etc.).
4. Creation and distribution of content
Some agencies, like So Bang, have a creative studio to produce content adapted to the platforms (videos, stories, sponsored posts, carousels, etc.).
5. Performance monitoring and optimization
tools social listening and data analysis : engagement rate, impressions, clicks, conversions, return on investment (ROI).
The relationship between agencies and influencers
Initially, influencer marketing on social media was built around stars and celebrities. A brand simply had to pay a celebrity to become its spokesperson and promote its message (its products, its services) in its social media posts.
Since then, things have changed completely. Today, influencers are often anonymous individuals, numbering in the thousands worldwide. More than the size of their community, it's their authenticity and connection with their followers that brands seek. Each influencer can specialize in one or more areas (luxury, fashion, sports, health, cosmetics, etc.).
In this rapidly expanding market, influencer agencies like So Bang step in to structure the relationship between brands and these influencers. It's truly about professionalizing influencer marketing practices.
Thus, the influencer agency will notably be responsible for formalizing the relationship with the influencers. Just like an employment contract, this means establishing a proper partnership that clearly outlines the terms of engagement, the time allocated to this activity, and of course, the compensation associated with this service.

The influencer agency: more than just an intermediary between influencers and brands
If the influence agency has become an indispensable interface between brands and influencers, it is also because it performs many other tasks than simply contracting between the two parties.
Thanks to its expertise in the digital communication and advertising sector, the influence agency also handles the recruitment of influencers, which is called “casting” in the jargon.
To achieve this, an influencer agency will often draw from its pool of influencers that it has previously built up. This is the case at So Bang, where our agency hasa platform of 30,000 influencers in France and internationally.
Thanks to this influencer marketing platform, our team can quickly map the profiles best suited to each client and each influencer marketing campaign. There's no magic formula for reliably identifying the best influencer. Only the agency's experience and expertise allow us to target the most appropriate contact for each situation.
To ensure it made the right choice, the influencer agency will also rely on tools and its data analysts. The goal is to measure the engagement (reach) generated by the influencer, as well as the conversion rate if the campaign involves a sales promotion. Everything said about the brand within the influencer's community is also closely examined.
If the results don't meet the client's expectations, the influencer agency will step in to adjust the strategy with the influencer. For example, by supporting the influencer in content creation. At So Bang, we have a creative studio in Paris that allows us to produce a wide range of content (photos, stories, videos, etc.). This can be helpful in assisting an influencer to promote a brand professionally.
As we can see, the relationship between brands and influencers is a complex process that requires genuine expertise. Influencer agencies like So Bang are there to maximize the effectiveness of this relationship while relieving each party of the most technical, administrative, and legal aspects. Entrusting your influencer marketing to a specialized agency should therefore not be optional. It is an essential condition for harnessing the full power of social media influence.
