The social media landscape in the United States continues to surprise with its creativity and diversity. American influencers are shaping new trends, redefining fashion codes, and driving engagement among ultra-active communities on TikTok, Instagram, and YouTube.
They are no longer content to be product showcases: they are true entrepreneurs, voices of progressive ideas and drivers of digital transformation.
At a time when influencer strategies are essential, their notoriety, authenticity, and the quality of their interactions constitute a major strategic asset for brands seeking impact, as perfectly illustrated by collaborations with the biggest players in the sector, from beauty to lifestyle. This top 10 looks at the essential profiles to watch to anticipate developments in the influencer marketing and perhaps grasp part of the secret of their meteoric rise.
Profile and power of American female creators: focus on the most notorious influencers
In today's digital ecosystem, the United States is establishing itself as a veritable hotbed of female talent, where influencers play a key role well beyond simply sharing content. Their prescriptive power extends across major verticals such as beauty, fashion, lifestyle, travel, and even health, allowing each demographic to identify with inspiring and accessible role models. Methodical analysis of profiles passing through specialized platforms such as Kolsquare reveals objective criteria of influence—credibility score, engagement rate, Earned Media Value – as audience and authenticity become central indicators of success.
Take Sammie (@itssammiee), for example, who has topped the charts thanks to her authentic and multidisciplinary approach. Across TikTok, Instagram, and X, Sammie regularly shares content that blends beauty, personal stories, and inspirational messages; she reaches nearly 957,000 followers on TikTok and displays consistent engagement (1,38% on Instagram), which demonstrates not only the size of her community but also her ability to spark conversations and build a loyal following. Her partnerships, particularly with @mixtiles, highlight the winning strategy of targeted collaborations and the strength of the Earned Media Value, estimated at over €17,000 on her Instagram posts.
Other profiles illustrate the range of expertise embodied by these KOL (Key Opinion Leaders). Olivia Rouyre (@oliviarouyre), with nearly a million followers on Instagram and a dynamic presence on YouTube and TikTok, is making a name for herself thanks to the diversity of her themes, alternating between fashion advice, beauty tips, and travel diaries. Her credibility score (83/100) ensures her the trust of brands and the loyalty of an audience eager for authenticity; a textbook case in terms of cross-platform (effective presence on several networks).
Key element: these influencers have engagement rates, sometimes above average, a sign of their commercial effectiveness. For example, Katie Thurston (@thekatiethurston) stands out with an engagement rate of 4.97% on her classic Instagram posts, proof of the emotional connection she has built with her followers, particularly on topics related to reality TV and daily life. This type of active interaction illustrates the growing importance of engagement compared to the simple size of the community, as explained by the analysis of influencer compensation or even the advanced selection methodologies applied in 2025.
| Name | Platforms | Followers | Themes | Credibility score | ER % (Commitment) |
|---|---|---|---|---|---|
| Sammie (@itssammiee) | TikTok, Instagram, X | ~957K / 894K / 55K | Beauty, Lifestyle, Fashion, Travel | 87/100 | 1.38 (IG) |
| Olivia Rouyre (@oliviarouyre) | Instagram, TikTok, YouTube | 952K / 691K / 784K | Travel, Fashion, Beauty, Lifestyle | 83/100 | 1.52 (IG) |

- Multiplicity of platforms : Instagram and TikTok remain essential, but YouTube, X and even playlists on other networks enrich the palette of influence.
- Height of credibility score : an essential guarantee of authenticity in the choice of premium partnerships.
- Real commitment : rate higher than 1% often a sign of sincere interactions, far from the simple number of subscribers.
- Cross-themes : multidisciplinarity makes it possible to address several audiences per content.
- Prescription power : high value-added collaborations, adapted to the requirements of a US market driven by innovations.
Far from confining themselves to a single specialty, American influencers are using a cross-disciplinary approach to unite diverse communities and strengthen their impact. Pioneers, they act as opinion leaders while highlighting socially responsible topics—mental health, diversity, empowerment—illustrating the growing role of networks as a lever for popular education and civic action. This synergy between visibility, engagement, and responsibility is combined with brands' desire to engage in more qualitative influence campaigns, as evidenced by the rise of collaborations with luxury brands (more details here).
News and changes in usage: increased visibility, new challenges
The American content creator market is evolving rapidly, with trends such as the integration of short video tools, the arrival of new platforms, and the diversification of formats (from e-commerce to podcasts). Influencers are not hesitant to adopt innovative strategies, from the advanced use of Instagram Marketplace (more info) to conquer new territories via YouTube Shorts or Pinterest, as evidenced by this comparative article (see here).
Faced with this increasing complexity, the KOL selection methodology remains focused on verified data and in-depth analysis of audience typology: quality of reach, value of shared content, impact on purchasing behavior. The gap in visibility and revenue between influencers, recently documented (read the study), pushes even more towards the requirement in the choice of collaborations and individual positions.
Themes, expertise and communities: towards segmented influence
The notoriety of American influencers is rooted in their ability to target highly responsive communities through highly specialized content. The fields of fashion, wellness, beauty, and health stand out, driven by profiles such as Shalom Blac (@SHALOMBLAC), who combines tutorials, personal testimonials, and motivational messages, or Zion Ko Lamm (@dr.zionko), a physician influencer known for popularizing medical information on Instagram and TikTok. One of the most striking aspects is the emergence of a hybridization pro/expert and creative/personal : medical, artistic or entrepreneurial specialization is anchored in an authentic narrative that builds long-term subscriber loyalty.
While the fashion and beauty sector dominates, other spheres are gaining ground, such as gaming (Jessica Blevins), parental humor (Terra Jolé) or song (Rachel Platten), proving the plasticity of US influence. This fine segmentation is accompanied by growing professionalism in career management: development of editorial planning, definition of Personal Branding on several networks, rigorous management of paid partnerships (see selection here).
- Beauty and Self-Acceptance : Shalom Blac breaks taboos by sharing his story of resilience.
- Life hacks and well-being : Zion Ko Lamm democratizes medical knowledge and encourages health prevention on TikTok.
- Family and humor : Terra Jolé portrays her life as a mother, breaking stereotypes and engaging an inclusive community.
- Music and storytelling : Rachel Platten brings her audience closer to her artistic creation, integrating live performance and raw emotion into her content.
- Fashion and e-commerce partnership : Hilary Clayton builds strong connections with her followers through 100% fashion, partnering with giants like Amazon Fashion or inspiring industry revolution (see the article).
| Influencer | Sector | Special feature | Main platforms | Major audience |
|---|---|---|---|---|
| Shalom Black | Beauty, Acceptance | Inspirational message of self-acceptance | YouTube, TikTok | US / international |
| Jessica Blevins | Gaming, Lifestyle | Ninja Manager, Entrepreneur | Instagram, TikTok | American young adults |
| Zion Ko Lamm | Health, Lifestyle | Popularized medical advice | Instagram, TikTok | Health community |
| Terra Jolé | Family, Entertainment | TV heroine & committed mother | Instagram, TikTok | American Families |
| Rachel Platten | Music, Lifestyle | Close proximity between fans and artists | Instagram, TikTok | US music fanbase |
Personalized storytelling is proving decisive: whether it's showing behind-the-scenes footage of a music video, sharing medical advice, or revealing family intimacy, this narrative mode fuels the attachment and loyalty of followers. Audiences are now educated to decode authenticity and value high-value content, a phenomenon accentuated by the emergence of trends such as “influencer shorts” on YouTube (more).
Focus on the creation of personal brands and multi-network synergies
Depending on the campaigns carried out with ready-to-wear or beauty brands (see the popularity of collaborations on swimwear: read here), the American influence values the construction of a universe specific to each designer. Some, like Hilary Clayton, exploit the image of the female entrepreneur, adding to the notoriety a message of business empowerment that meets the expectations of the new generation. This differentiating positioning, often relayed by in-depth articles like this fashion selection, anchors success in longevity and the ability to renew its codes. Synergies between networks maximize reach and allow content to be adapted for each audience, while maintaining editorial consistency essential to the strength of the personal brand.
Towards a Maturation of Influencer Marketing: Strategies, Opportunities and New Models
The landscape of influencer marketing is changing with the rise of data-driven analytics and the sophistication of online consumer expectations. Brands, whether in the luxury, wellness, or entertainment sectors, are now seeking not just awareness, but a real business efficiency measured by the conversion rate, engagement and quality of the dialogue generated by the influencer. This requirement for professionalization leads US creators to adopt quasi-entrepreneurial methods: fine-tuned contract negotiation, analysis of campaign ROI, management of digital reputation and adaptation of the message to each platform.
On the strategy side, the integration of best practices from international cases is essential, whether it is dealing with the virality of TikTok challenges or making the most of Instagram's new Creator Marketplace (more info), or even to resist the standardization of formats imposed by digital giants (decryption here). The opportunities are numerous: intelligent product placement, immersive storytelling, or co-creation of collections (clothing, accessories, cosmetics).
As they have grown, some influencers have gone on to build their own businesses or launch their own brands, illustrating the emergence of truly influential businesswomen. Examples include agreements with luxury brands or participation in the revolution in beauty standards on Instagram (see trends), contribute to strengthening the legitimacy and profitability of collaborations.
- Emphasizing credibility in the selection of KOLs (compliance score, quality of engagement).
- Adaptation of marketing discourse depending on the platform: short dynamic formats on TikTok, immersive stories on Instagram, in-depth YouTube vlogs.
- Valuing diversity by choosing ambassadors from all walks of life (e.g. doctor, entrepreneur, singer).
- Responsible commitment : promotion of societal issues (self-acceptance, mental health, body-positivity).
- Analysis of real profitability through Earned Media Value and effective engagement tools.
| Strategy | Expected effect | Application example | Benefits for the brand |
|---|---|---|---|
| Targeted collaboration with credible KOL | Increased engagement | #BodyPositivity TikTok Campaign | Loyalty and authenticity of the message |
| Personalized storytelling | Long-term loyalty | YouTube Vlog on Self-Acceptance | Emotion, attachment |
| Adaptation to short formats | Reaching Gen Z | TikTok trends, Instagram Reels | Immediate visibility |
| Sustainability of the influence project | Aligning brand values and audience | Health or body positive collaboration | Image strengthening |
Agencies and advertisers are now drawing inspiration from American success stories to refine their own systems, integrating the dimension of profitability, but also of responsibility (see the rise of trends such as skinnytok and their ethical management). The anticipation of these movements, coupled with constant monitoring of the evolution of formats (see news), guarantees brands and their ambassadors a lasting presence in a competitive environment where authenticity and commitment are the pillars of sustainable success.
Creating opportunities and challenges for new entrants
The success of the 10 American influencers featured serves as a strategic compass for new entrants, while also posing new challenges: the need to professionalize one's approach, cultivate originality in the face of fierce competition, secure smart contracts, and ensure the quality of the content produced. For brands, it's about spotting emerging talent likely to create a surprise, like the revelations documented in this list or international rankings like this one.
In this changing ecosystem, versatility, adaptability and a detailed understanding of algorithmic mechanisms are becoming essential prerequisites for all those who aspire to follow in the footsteps of these major figures in American digital.
