What Is Media Planning? A Complete Guide to Process, Frameworks, and Budget Optimization

PESO Model

The PESO model is an evolution of the Triple Media framework. It classifies media into four categories: Paid (paid advertising), Earned (press coverage and word of mouth), Shared (social media sharing), and Owned (company media). The key difference from Triple Media is separating social sharing from Earned Media into its own "Shared" category—a framework that more accurately reflects today's media landscape where social media influence has grown significantly.

For example, you might center your strategy on Paid when you need to generate leads quickly, or strengthen Earned and Shared when building brand awareness. The PESO model provides a useful structure for organizing "what to strengthen at which stage."

Seven Steps of Media Planning

Here are the seven fundamental steps for executing media planning in practice:

Step 1: Clarify Your Objectives

Start by clearly defining why you're advertising. Objectives generally fall into three categories: branding (enhancing brand value), awareness building (reaching more people), and conversion acquisition (driving specific actions like inquiries, purchases, or sign-ups). Since KPI setting and media selection change based on objectives, this step forms the foundation of your entire plan.

Step 2: Set Your Budget

Determine how much budget is available for advertising. A common approach is using CPA (cost per acquisition) as the basis—calculating backward from "how much can we spend per conversion" and multiplying by the target number of conversions. Other methods include the percentage-of-sales approach (allocating a fixed percentage of revenue to advertising) or benchmarking against competitor spending.

Step 3: Analyze Your Product/Service USP

USP (Unique Selling Proposition) refers to the distinctive strengths of your product or service. By clarifying what makes you superior compared to competitors, you can define the key points to communicate in your advertising. The clearer your USP, the more precise your target audience and media selection become, and the more persuasive your ad messaging will be.

Step 4: Define Your Target Audience

Define the specific audience that would value your USP. Going beyond basic demographics like "women in their 20s-30s" to create personas that incorporate lifestyle, values, and information-seeking behaviors dramatically improves media selection accuracy. Since the optimal media changes when the target changes, this step determines the precision of your entire plan.

Step 5: Design the Customer Journey

Map out the behavioral process your target audience follows from "discovering" your product to "purchasing" it. At each stage—awareness, interest, consideration, purchase, and repeat—identify which media your target is most likely to encounter. For example, TV commercials and social media ads for the awareness stage, search ads and owned media for the consideration stage, and retargeting ads and email marketing for the purchase stage.

Step 6: Select Your Media

Based on the preceding analysis, select the specific media for ad placement. Using frameworks like Triple Media and the PESO model, match each medium's reach characteristics, cost structure, and strengths to your needs. The concept of media mix—combining online and offline channels—becomes important here. For more on media mix, see our article "What Is Media Mix? How It Differs from Cross-Media."

Step 7: Determine Budget Allocation

Finally, determine how to allocate budget across your selected media. This is the most challenging step in media planning, and the one most directly tied to results. When historical performance data is available, use each medium's past sales contribution as a reference for adjustment. For new media, it's effective to reserve a portion of the overall budget as a test allocation and adjust based on results.

Three Keys to Successful Media Planning

1. Invest Time in Pre-Launch Design

Advertising outcomes are determined not after launch but during the design phase before launch. Running ads with vague objectives, targeting, and KPIs makes it impossible to review or improve afterwards. By clearly defining expected KPIs and decision criteria during the planning stage, communication with managers and executives becomes smoother, and reactive decision-making is avoided.

2. Combine Media Based on Their Characteristics

Each medium has its strengths and weaknesses. TV commercials excel at broad reach but struggle with detailed information. Search ads can reach high-intent audiences but aren't suited for awareness building. Social media ads drive engagement but may not directly convert. Understanding these characteristics and placing the right media at each stage of the customer journey is essential.

3. Optimize Budget Allocation with Data

The most challenging yet highest-impact aspect of media planning is budget allocation optimization. Whether you can objectively evaluate "how much should have gone to TV, search ads, and social media" and feed that into the next plan determines long-term marketing outcomes.

The methodology gaining attention for solving this challenge is MMM (Marketing Mix Modeling). MMM uses statistical models to analyze historical sales data alongside each medium's ad spend data, quantitatively calculating each medium's contribution to sales. By using MMM, you can optimize budget allocation based on data rather than gut feeling, dramatically improving media planning accuracy.

Practical Challenges in Media Planning and SaaS Solutions

In day-to-day media planning, most marketers face two key challenges. The first is data fragmentation—checking and compiling data from each platform individually (Google Ads, Meta Ads, Yahoo! Ads, LINE Ads, TikTok, X, etc.) requires enormous effort. The second is the difficulty of effectiveness measurement—determining how much each medium contributed to sales across multiple channels is impossible just by looking at individual platform dashboards.

NeX-Ray is a SaaS platform that solves both challenges simultaneously. By simply linking accounts with ad platforms and social media, it automatically collects data and lets you view cross-channel performance in a single dashboard. Report generation is also automated, freeing up time previously spent on data compilation for analysis and strategic planning.

Furthermore, it includes MMM (Marketing Mix Modeling) analytics capabilities that quantify each medium's sales contribution and derive optimal budget allocations. In other words, it enables an end-to-end media planning cycle of data collection → effectiveness measurement → budget allocation optimization → feedback into the next plan. With a free tier available, it's an accessible option for teams looking to evolve their media planning into a data-driven practice.

Conclusion

Media planning is the strategic planning process for delivering advertising through the optimal media, timing, and budget allocation to your target audience. Using frameworks like Triple Media and the PESO model, the plan is built through seven steps: clarifying objectives → setting budget → USP analysis → target definition → customer journey design → media selection → budget allocation.

What's essential for continuously improving media planning accuracy is data-driven effectiveness measurement and budget allocation optimization. MMM (Marketing Mix Modeling) is a powerful analytical methodology for this, and its adoption barrier has dropped significantly with SaaS platforms. Why not start by centralizing your marketing data and take the first step toward data-driven media planning?
