💡 What has changed (and what remains true)

In France, advertisers are progressively reallocating their budgets toward digital channels (search, social, retail media, video), but maintain TV and audio as powerful foundations for brand awareness.
AI is becoming integrated into media planning (scenario simulation, bid optimization, automated reporting) without replacing strategic thinking on objectives and audiences.
Retail media is now a pillar of the French media mix: it already accounts for several billion euros in France and offers direct measurement of sales.
The core principle does not change: a media strategy starts from business objectives, not trendy channels.

📊 The 5 steps of an effective media strategy

Step 1: define SMART objectives (awareness, traffic, leads, sales).
Step 2: identify and prioritize targets based on their media usage.
Step 3: choose channels according to their role in the funnel, not according to trends.
Step 4: allocate the budget while taking into account seasonality and key highlights.
Step 5: measure and iterate with KPIs defined before the launch.

🎯 The mistake not to make

Starting with channels (“we need to be on TikTok”) instead of starting with objectives.
Under-investing in brand awareness to put everything into direct performance — a strategy that quickly plateaus.
Neglecting measurement: without KPIs defined upstream, it is impossible to learn and improve the next campaign.

A media strategy is not a campaign plan. It is not a list of channels to activate, nor a budget to be divided into boxes. It is a framework that answers fundamental questions: why invest in media, for whom, with what message, on which channels, with what objectives, and how to verify that it works.

In 2026, this framework must incorporate new realities: AI in purchasing tools, the explosion of retail media, and the fragmentation of audiences across streaming, social networks, and traditional media. However, the core logic remains unchanged. And it is this logic that we will detail here.

Media strategy vs media plan: the difference

This is the first confusion to clear up, because it has significant practical consequences. Too many advertisers skip straight to the media plan without having a strategy, and are then surprised when the results are not there.

Media Strategy

The media strategy answers the questions “why” and “how”: why invest in one channel rather than another, how to balance awareness and performance, how to measure success.

It is a framing document that defines the priorities, the roles of each channel, and the success criteria.

Media Plan

The media plan is its operational translation: formats, volumes, broadcasting schedule, budgets per line, GRP per channel.

It is the daily working tool for the media buyer and the agency.

Building a media plan without a strategy is like building a house without architectural blueprints. The result might stand, but it will be difficult to optimize and adapt.

The 5 steps to build an effective media strategy

Step 1 - Define the objectives

Everything starts with business objectives, not with channels. These mandatory starting points translate into SMART media indicators (Specific, Measurable, Achievable, Realistic, Time-bound).

Awareness: +40% aided awareness in the area by the end of the year.
Traffic: +5,000 visits per month on the site via paid media.
Leads: 100 quote requests/month at a CPA < €50.
Sales: reach a ROAS of 4 on e-commerce in Q4.

Step 2 - Identify and prioritize targets

Defining your audience accurately is crucial for execution. An actionable media target must absolutely bring together several strategic criteria:

Socio-demographic data (age, gender, professional category, location).
Media behaviors (TV, social networks, radio, podcasts).
Stage in the buying journey (zero awareness or consideration phase).
First-party data (CRM database, website visitors, cart abandonments).

Step 3 - Build the media mix

The choice of channels logically follows the previous steps based on your target, your objectives, and your budget constraints.

Top of funnel (Awareness): TV, online video, OOH, audio, social branding.
Middle of funnel (Consideration): Non-branded search, social ads, display, content.
Bottom of funnel (Conversion): Branded search, retargeting, retail media, CRM.

Step 4 - Allocate the budget

Financial allocation depends on your overall brand awareness, the maturity of the brand in its market, and seasonality:

Prioritize the top of funnel (awareness) if your brand is still little known.
Concentrate your investments (40 to 50%) on your peak commercial periods.
Always dedicate a testing budget (10 to 20%) to explore new formats.

Step 5 - Define measurement and steering

KPIs and the tracking plan (pixels, UTMs, promo codes) must absolutely be set up before launching advertising campaigns.

This regular monitoring allows you to adjust your targeting, test your creatives, and continuously reallocate budgets toward the top-performing channels.

What changes in 2026: AI, retail media, streaming

👉 AI in media planning and purchasing

Artificial intelligence is now integrated at all levels of the advertising chain. In planning: simulation of media mix scenarios, incremental audience forecasting, budget allocation recommendations. In purchasing: smart bidding, real-time bid optimization, automatic allocation between channels. In reporting: anomaly detection, automatic optimization recommendations.

This is not a revolution but an acceleration. AI tools do not replace strategy; they make it easier to test and adjust. Critical skills shift toward defining objectives and rules of the game, rather than the manual steering of campaigns.

👉 Retail media in hyper-growth

Retail media (advertising sold by retailers on their own platforms) has become a pillar of the mix for consumer goods brands. It combines transactional data and direct measurement of sales: a rare and valuable combination.

In France, the retail media market now exceeds several billion euros and continues to grow. For brands present in mass retail, it is a lever difficult to ignore: purchasing data provides the most precise targeting possible to target actual or similar buyers.

👉 Video and streaming

Video consumption is shifting toward streaming, connected TV, and AVOD platforms (advertising on free streaming content). For advertisers, this opens up access to the power of TV with finer targeting and interactive formats: clickable spots, QR codes, mobile/TV synchronization.

Linear TV remains a powerful mass media, but connected TV progresses each year. 2026 video strategies generally combine both: linear TV for reach and shared moments (sports, prime time), connected TV and streaming for targeting and interactivity.

The 10 errors that sabotage a media strategy

❌ 1. Starting with channels instead of objectives

Thinking “we are going to do TikTok” before defining what you want to achieve is the perfect recipe for spending with no return. The channel follows the objective and the target, never the other way around.

❌ 2. Confusing a media plan with a media strategy

Producing a campaign plan without a strategic framework (priorities, trade-offs, success measurement) is like building a house without blueprints. The plan gets optimized over time; the strategy gives it its direction.

❌ 3. Under-investing in brand awareness

Brands that allocate their entire budget to direct performance see their acquisition costs steadily increase because they fail to feed top-of-funnel demand. TV, radio, and OOH create the demand that search and retargeting will eventually capture.

❌ 4. Judging everything by short-term CPA or ROAS

Applying performance KPIs to awareness channels leads to cutting them at the wrong time. A TV campaign with a disappointing direct ROAS can generate an increase in branded searches and indirect conversions that do not show up in that specific campaign's dashboard.

❌ 5. Neglecting creative consistency

Different messages on each channel, without a common thread, dilute brand equity. Repeating a consistent message across multiple channels is one of the keys to advertising recall.

❌ 6. Multiplying channels without management capacity

Being present on 8 channels with a €20,000 budget and a one-person team means being present at €2,500 everywhere. Below the minimum visibility threshold, you pay with no actual impact.

❌ 7. Freezing the strategy for the entire year

The market evolves, costs change, and performance varies by season. A good strategy incorporates regular test-and-learn loops (creative A/B tests, channel experiments, budget adjustments) rather than a plan carved in stone in January.

❌ 8. Ignoring first-party data

With the gradual phase-out of third-party cookies, proprietary data (CRM database, website visitors, buyers) has become a strategic asset. Advertisers who have not collected and structured it are at a disadvantage in their targeting and activation capabilities.

❌ 9. Failing to prepare measurement in advance

Tagging pages, installing pixels, defining conversion events, setting up UTMs, and establishing dashboards must all be in place before launch. Data collected without a structured framework is useless for optimization.

❌ 10. Underestimating the creative assets

A good media plan with bad creative assets yields poor results. Creative execution is often the most impactful variable on a campaign's performance. Investing in creative quality is just as important as optimizing targeting.

FAQ: Media strategy

What is a media strategy?

A media strategy is the framework that defines why and how an advertiser invests in advertising to achieve their marketing objectives. It includes defining objectives, identifying target audiences and their media usage, choosing channels and their role in the customer journey, budget allocation, and the measurement plan. It differs from the media plan, which is its operational translation.

What are the steps to build a media strategy?

Five structuring steps: 1) define SMART objectives linked to business goals, 2) identify and prioritize target audiences and their media usage, 3) choose channels and define their role in the funnel, 4) allocate the budget while taking seasonality into account, 5) define KPIs and the measurement plan before the launch.

How do you choose your advertising channels?

The choice of channels follows the objective and the target audience, not current trends. For broad awareness: TV, online video, OOH, radio. For consideration and traffic: search, social ads, display. For conversion: intent-based search, retargeting, retail media. For retention: CRM, email, customer retargeting.

What share of the budget should be allocated to awareness vs performance?

There is no universal ratio, but marketing studies show that brands under-investing in awareness in favor of performance see their acquisition costs steadily increase. Established brands generally allocate 40% to 60% to brand and 40% to 60% to performance. Brands in a launch phase may initially go up to 70-80% in awareness.

How is AI changing media planning in 2026?

AI operates on three levels: in planning (scenario simulation, audience forecasting, mix optimization), in purchasing (smart bidding, automatic bid optimization), and in reporting (anomaly detection, recommendations). It accelerates optimization but does not replace strategic thinking on objectives and trade-offs.

What is retail media and why is it important?

Retail media refers to advertising sold by retailers (Amazon, major supermarket chains) on their digital platforms, leveraging their purchasing data. It is a growing pillar of the media mix because it combines highly precise targeting (transactional data) with direct measurement of sales. In France, it now exceeds several billion euros and continues to grow.
