At Clutch, we believe trust is the foundation of every business relationship. Our mission is to help buyers make confident, data-backed decisions informed by real client experiences.
Every review on Clutch undergoes a rigorous, human-led verification process to make sure it’s valid. Our team of specialists confirms the identity of each reviewer, ensures the project is legitimate, and only publishes reviews that meet our strict criteria.
Verification doesn’t stop at the point of publication. Our Trust & Safety team routinely audits older reviews against our guidelines. When reviews fall short of our standards, we remove them.
We evaluate service providers using a structured methodology that combines:
- In-depth client interviews and ratings
- Comprehensive project details
- Market presence
- Portfolio examples and industry recognition
This data powers tools like the Leaders Matrix, which helps you compare agencies directly. Our research team curates rankings by weighing verified reviews most heavily, so the most trusted and experienced providers rise to the top.
Using this unique combination of verified client feedback and provider-supplied insights, Clutch distills the most important details into clear, digestible summaries so you have everything you need to make confident, informed decisions quickly.
We take fraud seriously. Providers who violate our guidelines may face lower rankings, restricted visibility, or removal from the platform altogether.
Clutch’s commitment to transparency is ongoing. We’re constantly refining our systems to protect the integrity of reviews and support you in finding the right agency.

Instagram Stories: Perfecting "The Hook" and How To Get It Right
Instagram Stories play an essential role in connecting and strengthening relationships with audiences. Discover how you can maximize it to leverage your brand.
Top YouTube Influencer Marketing Companies
A YouTube influencer marketing company helps brands promote their products or services by partnering with YouTube creators who have loyal and engaged audiences. These companies handle the entire process, from identifying suitable influencers and negotiating contracts to managing creative content and tracking campaign results. They ensure the influencer’s content aligns with the brand’s goals and messaging while maintaining authenticity and audience trust. In addition to campaign execution, they provide data analysis, reporting, and strategic insights to measure performance and optimize future campaigns. Their goal is to drive awareness, engagement, and conversions through well-planned influencer collaborations on YouTube.
Start by defining your campaign goals, such as boosting awareness or driving sales. Look for an agency with proven YouTube experience and ask for case studies and examples of similar campaigns. Make sure they have a strong influencer network, transparent pricing, and clear communication. Confirm they can handle content approvals, legal compliance, and detailed performance reporting. To compare options and read verified reviews, check platforms like Clutch.
YouTube influencer marketing companies offer a range of services designed to help brands connect with the right creators and run effective video campaigns. These typically include:
- Influencer Identification and Vetting
- Campaign Strategy and Planning
- Contract Negotiation and Talent Management
- Content Oversight and Approval
- Performance Tracking and Reporting
- Compliance and Disclosure Management
- Creative Direction and Collaboration
- Paid Amplification and Media Buying
- Post-Campaign Analysis
Some agencies offer multi-platform campaigns that may also include YouTube Shorts, Instagram, and even TikTok.
Hiring a YouTube influencer marketing company typically costs between $25 and $49 per hour for agency services. Total campaign costs vary based on project scope, influencer reach, and deliverables. Influencers themselves charge separately. Nano influencers may ask for $100 to $200 per video, while mid-tier creators with 100,000 to 500,000 subscribers can command $500 to $5,000 or more per integration. Additional expenses may include content production, legal contracts, and analytics tools.
Before hiring a YouTube influencer marketing company, it's important to ask key questions that help you evaluate their experience, process, and fit for your brand:
- What experience do you have specifically with YouTube campaigns?
- Can you share case studies or examples of successful YouTube influencer campaigns?
- How do you select and vet YouTube influencers?
- Do you handle contracts, negotiations, and usage rights?
- What metrics do you track to measure campaign success?
- How involved will I be in content approval?
- Do you offer paid amplification or media buying on YouTube?
- What is your pricing structure, and what does it include?
- How do you ensure FTC compliance and proper disclosures?
You can also research YouTube influencer marketing companies on Clutch. Read verified reviews and compare their pricing, projects, and feedback.
