Why Trust Clutch

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.

OOH Media Buying Company FAQs

Experienced service providers pair traffic data with mobile device IDs, geo-fencing, and brand-lift surveys to attribute in-store visits, website traffic spikes, or app downloads to specific OOH placements. They may also track QR code scans or custom URLs placed on creatives for direct engagement metrics.

Traditional media buying agencies cover TV, radio, print, and digital, whereas OOH specialists focus exclusively on outdoor inventory. Dedicated OOH agencies often have deeper relationships with local media owners and proprietary mapping tools that optimize placements block-by-block, giving them an edge when negotiating rates and securing high-impact locations.

OOH media buying companies plan, negotiate, and manage outdoor advertising campaigns on behalf of brands. They analyze target demographics and traffic patterns, secure ad inventory across billboards, transit shelters, street furniture, and digital screens, and oversee creative specifications, installs, and performance tracking. At the end of the day, their goal is to place your message in the right location at the right time to maximize impressions and ROI.

Out-of-home media buying providers aim to help brands reach their target audience in public spaces. These vendors offer a myriad of services such as:

  • Market and audience research
  • Location scouting and inventory mapping
  • Rate negotiation and contract management
  • Creative formatting and production coordination
  • Campaign trafficking, monitoring, and optimization
  • Post-campaign analytics and reporting

Some full-service agencies also integrate mobile geofencing, QR codes, or attribution studies to connect offline impressions with digital actions.

Pricing for OOH media buying projects varies by market size, format, and campaign duration. Smaller regional campaigns can start around $5,000–$15,000 per month, while national multi-market rollouts often range from $50,000–$250,000+ monthly.

Additionally, agencies usually charge a management fee — often around 10%–20% of media spend — or bundle services into a fixed retainer. Always request a detailed media plan that breaks down placement costs, production, and agency fees before signing.
