Media Buying: What It Is and How It Works

You could have the most creative ad in your industry—sharp messaging, stunning visuals, and a compelling call to action. But if it’s shown in the wrong place, at the wrong time, or to the wrong audience, it won’t work. That’s where media buying comes in! It’s all about making sure your ad shows up where it matters most, whether it’s on your audience’s favourite social platform or streaming service. In fact, global digital ad spending is set to top $667 billion in 2024, with mobile and video ads leading the charge.

Media buying lets you pinpoint exactly when and where your ad should be, ensuring it reaches the right people at the right moment. With more businesses shifting focus to video ads, especially on platforms like YouTube, it's clear: a smart media buy isn’t just about visibility—it’s about creating real connections.

What is Media Buying?

Media buying is the strategic process of purchasing advertising space across various platforms to maximise visibility and ROI. This involves identifying where, when, and how often to place ads so they reach the most relevant audience at the lowest cost per result.

Media buying covers both traditional formats—like television, radio, print, and outdoor—as well as digital channels such as social media, websites, streaming platforms, and apps. A successful media buy ensures that the advertisement appears in the right context, enhancing relevance and engagement. For example, placing a skincare ad next to a beauty blog or during a beauty influencer’s YouTube video boosts its effectiveness.

Media buyers work closely with media planners. While media planners develop the overarching strategy based on campaign objectives, media buyers execute that plan by negotiating and securing ad placements within the set budget and timeline.

Importance of Media Buying

Media buying is critical for achieving campaign success. Even the most creative ads can underperform if they aren’t strategically placed. Effective media buying ensures that the target audience not only sees the ad but does so at the right time and frequency to take action.

Here’s why media buying matters:

• Maximises reach among the intended audience through optimal ad placements
• Reduces cost per action by securing value-added impressions or bundled deals
• Strengthens brand visibility across multiple channels working in tandem—like combining radio ads with Instagram Stories for greater impact

Skilled media buyers also bring negotiation expertise to the table, helping brands get more for their money, often securing bonus impressions or better time slots at no extra cost.

Media Buying vs. Media Planning

Although closely linked, media buying and media planning serve different roles:

Media Planning

Media planning comes first and lays out the foundation for media buying. It defines:

• Campaign goals (e.g., awareness, conversions)
• KPIs (e.g., impressions, website visits, app downloads)
• Audience insights (e.g., demographics, behaviour, interests)
• Budget allocation
• Timeline for creative development and campaign execution
• Media mix (TV, print, digital, etc.)
• Measurement tools and success metrics

Media Buying

Media buying brings the media plan to life by:

• Negotiating and purchasing media slots
• Securing placements at ideal times and locations
• Monitoring ad delivery and adjusting placements as needed
• Ensuring delivery aligns with planned KPIs

Together, media planning and media buying ensure that campaigns are not only creative but also data-driven and cost-effective.

Types of Media Buying

Media buying methods vary depending on the platform, budget, and campaign goals. Here are the main types:

1. Direct Buying

   • Ads are purchased directly from media owners like TV channels, websites, or print publishers.
     Offers fixed placements and guaranteed impressions but may lack scale.

2. Programmatic Buying

   • Automated ad buying using software platforms (Demand Side Platforms or DSPs)
   • Leverages real-time data and audience targeting
   • Allows for real-time bidding (RTB), optimisation, and better ROI

3. Agency Involvement

   • Brands often work with media buying agencies that bring expertise, technology, and access to premium inventory.
   • Agencies can manage both traditional and programmatic buys.

Each method has its advantages. Direct buying provides control, while programmatic offers scale, precision, and efficiency.

Media Buying Process

The media buying process is a well-organised, step-by-step approach to securing the best placements and optimising campaigns for maximum ROI. It involves the following stages:

1. Set Goals and Budget:
   The first step in media buying is defining clear objectives. What does the campaign aim to achieve? Whether it's brand awareness, lead generation, or conversions, the campaign’s goals should guide the media buying strategy. From there, a budget is allocated across various platforms, keeping in mind which channels will yield the best results.
    
2. Select Platforms:
   Once goals and budget are set, the next step is selecting the platforms that will most effectively reach the target audience. This could involve choosing between traditional media like TV or radio or digital platforms such as social media, search engines, or display networks, depending on where the target demographic is most active.
    
3. Negotiate Rates:
   Negotiating the rates is a crucial step, whether buying directly from media owners or via programmatic buying platforms. The objective is to secure the best placements and pricing. Negotiation skills come into play here as media buyers try to get bonus impressions, premium slots, or other value-added benefits at no extra cost.
    
4. Launch Campaigns:
   Once the media is purchased, the creative assets (ads) are distributed according to the specifications of each platform. This stage involves uploading the creatives and ensuring they are optimised for the particular formats required by each medium, such as display ads, video spots, or sponsored posts.
    
5. Monitor and Optimise:
   After launching, media buyers need to closely monitor campaign performance in real time. Analytics tools help track KPIs such as clicks, impressions, conversions, and engagement. Based on this data, adjustments are made to optimise the campaign. This might involve changing bids, reallocating the budget to better-performing placements, or testing new creatives.
    
6. Post-Campaign Reporting:
   After the campaign ends, performance is thoroughly reviewed. A detailed report comparing actual results with KPIs helps assess whether the campaign met its objectives. The insights gained from this analysis inform future media buying decisions, ensuring continuous improvement.
    

Key Factors in Media Buying

Successful media buying depends on various factors that influence the overall effectiveness of the campaign. These key factors should be considered at every stage:

1. Brand Safety:
   Brand safety is critical to ensuring that your ads don’t appear in inappropriate or misleading environments. This means working with trusted media outlets or using programmatic platforms that offer brand-safety measures to filter out potentially harmful or controversial content.
    
2. Performance Optimisation:
   Optimising campaign performance is a constant process. Media buyers use A/B testing, bid adjustments, and frequency capping to ensure campaigns perform at their best. Many programmatic platforms offer built-in features to optimise campaigns automatically based on real-time data and performance metrics.
    
3. Cohesive Strategy:
   A cohesive strategy ensures that all media channels work in tandem to deliver a unified brand message. Disjointed or inconsistent campaigns can confuse the audience and reduce the overall impact. Whether it's through cross-channel messaging or retargeting, a consistent strategy reinforces the brand’s narrative and helps maintain customer engagement.
    
4. Measurement and Analytics:
   Data-driven decision-making is at the heart of effective media buying. By monitoring real-time performance through analytics platforms, media buyers can identify what’s working and make necessary adjustments to improve campaign performance. Regularly tracking metrics such as impressions, CTR, and conversion rates allows for continuous optimisation and better ROI.
