Media buying firms manage major advertising platforms where your audience spends time, both online and offline. They handle campaigns across multiple channels to reach people at different stages of the buying journey and to improve overall results.

• Paid search and social 
  Agencies run ads on platforms like Google, Bing, Facebook, Instagram, LinkedIn, and TikTok. These channels drive targeted traffic, leads, and sales based on user intent and behavior.
• Programmatic and display 
  They use demand-side platforms to buy ad space automatically across websites and apps. This includes banner, video, and native ads, all optimized in real time.
• CTV and OTT (Streaming ads) 
  A media buying firm places ads on streaming services and smart TVs to help brands reach audiences who no longer watch traditional cable.
• Traditional media 
  They still buy ad space on TV, radio, print, and billboards when it makes sense for reach and brand awareness.
• Audio and Digital Out-of-Home (DOOH) 
  Ads on Spotify, podcasts, and digital billboards in public spaces like malls, highways, and transit stations.

Media planning agencies decide where, when, and how to advertise. Media buying firms execute that plan by purchasing ad space and managing placements.

Planning sets the strategy; buying delivers the ads.

Media buyers choose channels by matching audience behavior, campaign goals, and budget to the platforms most likely to deliver results. They rely on data to see where people spend time and shift spend toward what performs best. 

Core logic stays the same at every level: reach the right audience, support the campaign goal, and invest where return is strongest. 

Media buying firms usually charge a percentage of your ad spend, typically between 3% and 10%, or a flat monthly fee depending on campaign size. Smaller budgets pay higher percentages, while large budgets get lower rates.

Typical pricing models:

• Percentage of ad spend: 5% to 10% for most campaigns
• Flat monthly fee: $2,000 to $15,000+, depending on scope
• Project-based (strategy/planning): $1,500 to $50,000+
• Setup fees: 2% to 3% of initial spend (one-time)

How pricing scales:

Costs depend on your ad budget, the number of channels, campaign complexity, targeting depth, creative needs, and the amount of ongoing management and reporting required.

You are not just paying for ad placement. You're paying for strategy, execution, optimization, and performance improvement. 

There is no strict minimum spend, but in practice, you need at least $1,000 to $3,000 per month to generate enough data for optimization and results. Very small budgets, like $5 per day, rarely perform because they don’t generate enough clicks or conversions.

For better performance, campaigns should aim for at least 30 conversions per month, which often requires higher spend depending on your cost per click.

More advanced channels like programmatic or CTV usually require $5,000 to $10,000+ to run effectively, and many agencies set similar minimums to ensure campaigns are worth managing.

You can see initial results in 2 to 4 weeks, but most campaigns need 2 to 3 months to stabilize and deliver consistent ROI.

Early signals like impressions, clicks, and some leads often appear within days to a few weeks, especially on paid social and search. However, platforms need time to learn and optimize, so stronger and more reliable results usually take 8 to 12 weeks.

For more complex campaigns, such as B2B or high-ticket offers, meaningful revenue impact can take 3 to 6 months due to longer sales cycles and ongoing optimization.
