Influencer marketing is no longer just a trend: it's a major strategic lever for brands in 2025. As mistrust of traditional advertising continues to grow, companies are relying on authentic voices to connect and influence purchasing decisions. This article takes you on a journey through time, from the golden age of celebrities to the age of artificial intelligence, to understand how influence has become a formidable weapon at the heart of modern marketing strategies.
What is influencer marketing?
Influencer marketing is a communication strategy based on collaboration between a brand and influential personalities - influencers - who are able to recommend products or services to their community. Through their proximity, authenticity and ability to generate engagement, these content creators become key partners in the digital ecosystem.
Defining influencer marketing
In concrete terms, influencer marketing involves using the visibility and credibility of a person on social networks, a blog or a YouTube channel to convey a message to a targeted audience. These content creators are chosen not only for their audience, but also for the trust they inspire.
Influencer marketing objectives
Influencer marketing has multiple objectives: to improve brand awareness, reinforce legitimacy, generate engagement and increase sales. In 2025, this approach is also becoming a tool for customer loyalty and co-creation.
Key benefits
Thanks to influencer marketing, brands gain access to an ultra-targeted audience while benefiting from a much higher rate of engagement than traditional campaigns. The authenticity of the messages also helps to create a lasting emotional bond between the brand and its consumers.
A look back at the evolution of influencer marketing
From celebrities to early influencers
Before the rise of digital, celebrities from television, film and sport were already acting as ambassadors. In those days, campaigns relied on their notoriety to appeal to the general public via television, radio or the press.
The social networking explosion
The advent of platforms like Instagram, YouTube, Snapchat and TikTok has enabled new, more accessible figures to build their own audiences. Influencer marketing has thus moved from an elitist approach to a community-based strategy, where each niche finds its spokesperson.
Professionalization of the sector
Since 2016, agencies such as ValueYourNetwork agencies have structured the sector, supporting brands in choosing the right influencers, creating tailor-made campaigns and analyzing performance. Today, these agencies have become strategic players in the success of digital campaigns.
Influencer marketing in 2025: where do we stand?
Platforms at the heart of strategy
Instagram remains a mainstay, but TikTok, YouTube Shorts, LinkedIn and Twitch are gaining in power. Each network has its own codes, and brands need to adapt their message according to the channel and target audience.
The rise of micro-communities
All micro-influencers (5,000 to 50,000 subscribers) are booming. Their closeness to their audience and high engagement rates make them particularly attractive to brands seeking authenticity and impact.
Technology for influence
AI now plays a central role: identifying the best profiles, predicting campaign results, creating personalized content... Brands are relying on data to optimize every aspect of their influencer strategy.

Best practices to adopt
Intelligent planning
Before launching a campaign, define your objectives (awareness, traffic, sales), your budget and the indicators to be monitored. This will help you make the right choices.
Long-term collaboration
Long-term partnerships are more effective than one-off collaborations. This strengthens the credibility of the message and builds audience loyalty.
Continuous measurement and adjustment
Thanks to advanced analysis tools, you can measure performance in real time: click-through rates, impressions, sales generated... Then adjust your strategy according to the results observed.
