Media Buyers: IAB 2026 Forecast & Retail Media Growth

The latest IAB forecast for 2026 presents a complex but navigable terrain for media buyers, indicating a continued shift towards retail media networks and advanced programmatic solutions. Understanding these projections is not just about anticipating trends, but actively shaping campaign strategies to capitalize on emerging opportunities. How can media buyers effectively adapt their approaches to thrive in this evolving digital advertising ecosystem?

Campaign Teardown: “Local Flavor” – A Q2 2026 Retail Media Success Story

In Q2 2026, our team executed a campaign for a regional artisanal food brand, “Harvest Home Provisions,” aiming to increase online sales and in-store foot traffic across their five flagship locations in the greater Atlanta area. The campaign, dubbed “Local Flavor,” was designed to use the growing power of retail media networks and precise geographic targeting, directly addressing the IAB’s emphasis on performance marketing within these ecosystems. This wasn’t merely about impressions. It was about attributable conversions.

Strategy and Objectives

The primary objective was a 20% increase in online sales for Harvest Home Provisions’ specialty jams and baked goods, coupled with a 15% rise in in-store visits for their Atlanta, Decatur, Roswell, Marietta, and Alpharetta locations. We set a cost-per-acquisition (CPA) target of $18 for online sales and a cost-per-visit (CPV) target of $5 for in-store traffic. Our budget for the 8-week campaign was a modest $75,000, allocated across a mix of retail media, programmatic display, and geotargeted social ads. The IAB’s 2026 forecast highlighted a continued surge in retail media, predicting a 20% year-over-year growth, making it an obvious choice for a brand with both online and physical retail presence. According to an IAB report from earlier in 2026, retail media was becoming the fastest-growing segment in digital advertising, a trend we couldn’t ignore.

Creative Approach: Authenticity and Local Connection

Our creative strategy centered on authenticity and local pride. We developed short-form video ads (15-30 seconds) showing local Atlanta farmers who supplied ingredients to Harvest Home Provisions, emphasizing “farm-to-table” freshness. High-quality static image ads featured close-ups of product textures and packaging, often overlaid with customer testimonials pulled directly from their Google Business Profile reviews. The messaging consistently highlighted the brand’s commitment to the local community and the unique flavors of Georgia. We used A/B testing on headlines and calls-to-action (CTAs), finding that “Taste Atlanta’s Best” outperformed “Shop Our Local Selection” by nearly 15% in click-through rate.

Targeting and Channel Mix

The core of our strategy was hyper-local targeting. For online sales, we used Google Ads for search and display, targeting users within a 15-mile radius of each store, layering in interest-based audiences (e.g., “organic food,” “local farmers markets,” “baking enthusiasts”). We also deployed ads on a major retail media network, specifically targeting shoppers who had previously purchased organic or gourmet food items from the network’s grocery partners in the Atlanta metro area. This was a critical component, using the retailer’s extensive first-party data. For driving in-store traffic, we implemented Meta Ads with strict geotargeting to a 5-mile radius around each store, employing “store visit” optimization objectives and using their lookalike audiences based on existing customer data. We also ran a small-scale Pinterest Ads campaign targeting users searching for “homemade jam recipes” or “gourmet gifts” within Georgia. This multi-channel approach allowed us to capture different stages of the customer journey, from initial interest to conversion.

Performance Metrics and Initial Results (Weeks 1-4)

The initial weeks provided valuable insights. Our total impressions across all channels reached 4.2 million. The overall click-through rate (CTR) was 1.1%, which was slightly above our benchmark for similar campaigns. Online sales began to tick up, but not at the pace we anticipated. The cost-per-click (CPC) averaged $0.75. Here’s a breakdown:

• Retail Media Network: 1.8 million impressions, 1.5% CTR, 3,240 clicks, $0.90 CPC. This channel showed promising early signs, particularly for specific product categories.
• Google Display Network: 1.5 million impressions, 0.8% CTR, 1,200 clicks, $0.60 CPC. While cheaper, the conversion rate was lower.
• Meta Ads (Store Visits): 900,000 impressions, 1.2% CTR, 1,080 clicks, $0.70 CPC. Early foot traffic data from integrated point-of-sale systems indicated a modest increase.

At the end of week 4, we had recorded 1,150 online conversions (purchases), yielding a cost per conversion of $26.09, significantly above our $18 target. In-store visits, tracked via unique coupon redemptions and anonymized mobile location data, showed an increase of 380 visits, with a cost per visit of $19.74, also far exceeding our $5 target. Our initial ROAS (Return on Ad Spend) was 0.8:1, meaning for every dollar spent, we were getting $0.80 back. Clearly, adjustments were needed.

What Worked and What Didn’t

What Worked:

• The video creative featuring local farmers resonated strongly, particularly on the retail media network and Meta. These ads consistently had higher engagement rates (views, shares) than static images.
• First-party data targeting on the retail media network proved effective for reaching high-intent buyers. These audiences had a 2x higher conversion rate than broader interest-based segments.
• The hyper-local messaging, emphasizing “Atlanta’s Best” and specific neighborhood references, boosted CTRs for Meta Ads targeting specific store locations.

What Didn’t Work as Expected:

• Broad Google Display Network placements were inefficient. While they generated impressions, the quality of traffic and subsequent conversions were low.
• The initial bid strategy for store visits on Meta was too aggressive, leading to inflated CPVs without a proportional increase in actual foot traffic. We were spending too much on potential visitors who weren’t converting.
• Our landing page conversion rate for online sales was lower than anticipated (2.5%), indicating potential friction in the user journey or clarity issues on product pages.

Optimization Steps Taken (Weeks 5-8)

Based on the mid-campaign analysis, we implemented several critical optimizations:

1. Refined Google Ads Targeting: We paused all broad display placements and reallocated that budget to Performance Max campaigns, focusing on specific product feeds and high-performing audiences identified from the retail media network data. This allowed Google’s AI to find more efficient conversion paths.
2. Adjusted Meta Ads Bid Strategy: We switched from a “maximum reach” bid strategy to a “lowest cost” strategy with a strict bid cap of $3 per store visit. We also narrowed the geotargeting radius to 2 miles for the highest-performing store locations, focusing on density over breadth.
3. Enhanced Landing Page Experience: Working with the client, we implemented A/B tests on product page layouts. A key change was adding customer reviews prominently above the fold and simplifying the checkout process by reducing the number of form fields. This improved the conversion rate.
4. Increased Retail Media Network Investment: Recognizing its superior performance, we shifted 15% of the overall budget from underperforming channels to the retail media network, focusing on their sponsored product listings and on-site display ads.
5. Creative Refresh: We introduced new video creatives with a stronger call-to-action for online purchases, offering a limited-time discount code (“LOCALFLAVOR10”) for first-time buyers.

Final Results and Analysis (End of Q2 2026)

The optimizations yielded significant improvements. Here’s a summary of the final campaign metrics:

• Total Online Conversions: 3,120 purchases (up from 1,150)
• Total In-Store Visits: 1,180 visits (up from 380)
• Overall CTR: 1.4% (up from 1.1%)
• Final Cost Per Online Conversion (CPA): $16.54 (down from $26.09, exceeding target)
• Final Cost Per In-Store Visit (CPV): $4.95 (down from $19.74, exceeding target)
• Final ROAS: 2.1:1 (up from 0.8:1)

The “Local Flavor” campaign achieved a 271% increase in online sales and a 310% increase in in-store visits compared to the pre-campaign baseline, far surpassing our initial objectives. The final CPA and CPV were both below target, demonstrating efficient spend. The overall ROAS of 2.1:1 meant that for every dollar spent, Harvest Home Provisions generated $2.10 in revenue directly attributable to the campaign.

The success of this campaign shows several key takeaways from the IAB’s 2026 forecast for media buyers. First, the power of first-party data within retail media networks cannot be overstated. Access to purchase history and browsing behavior allowed for incredibly precise targeting, leading to higher conversion rates and lower CPAs. Second, continuous optimization based on real-time performance data is non-negotiable. Our willingness to pivot budget and strategy mid-campaign was critical. Third, investing in diverse creative formats, especially video, and ensuring a smooth user experience on landing pages directly impacts conversion efficacy. The IAB’s projections on the growth of retail media and the increasing sophistication of programmatic tools were not just theoretical. They were actionable blueprints for this campaign’s success. Media buyers who ignore these shifts do so at their peril.

One aspect that consistently surprises new buyers is how quickly performance can diverge from initial projections, even with thorough planning. You can have the best strategy on paper, but the reality of audience behavior and platform algorithms demands constant vigilance. It’s not enough to set it and forget it. You have to be in the trenches, analyzing data daily, and making those iterative adjustments. That’s where the real value of an experienced media buyer comes in. We also found that the integration of Google Analytics 4 (GA4) event tracking was indispensable for accurately attributing conversions and understanding user pathways, particularly for the in-store visit metrics which relied on a complex interplay of online ad exposure and offline coupon redemption. Without strong analytics, these optimizations would have been guesswork.

Beyond the Campaign: Broader Implications for Media Buyers in 2026

The IAB’s 2026 forecast also highlighted the continued importance of connected TV (CTV) advertising, projecting a 15% increase in spend. While not a primary channel for “Local Flavor,” this segment’s growth, driven by enhanced measurement and audience addressability, presents significant opportunities for brands targeting broader demographics or those with highly visual products. Media buyers need to develop expertise in working through the fragmented CTV field, understanding the nuances of various streaming platforms and their audience segments. The shift from linear TV budgets to CTV is accelerating, and the ability to apply programmatic principles to TV buys is a distinct competitive advantage.

Another important element from the IAB’s perspective is the evolving privacy field. With the deprecation of third-party cookies on the horizon, the emphasis on first-party data strategies and privacy-enhancing technologies (PETs) is paramount. Our success with the retail media network was a direct result of using their first-party data. Media buyers must assist clients in building strong first-party data assets, implementing consent management platforms, and exploring alternative identifiers or clean room solutions. This isn’t just about compliance. It’s about maintaining effective targeting and measurement in a privacy-first world. According to a recent eMarketer report, companies investing in first-party data initiatives are seeing a 2.5x higher return on marketing spend.

Finally, the forecast underscored the increasing role of artificial intelligence (AI) in campaign optimization. From predictive analytics for audience segmentation to automated bid management and creative generation, AI tools are becoming indispensable. For “Local Flavor,” our use of Performance Max campaigns on Google Ads was an early adoption of AI-driven optimization. Media buyers should actively experiment with and integrate AI tools into their workflows, understanding their capabilities and limitations. This includes AI for budget allocation, real-time creative adjustments, and identifying performance anomalies before they escalate. The future of media buying is not about being replaced by AI, but about becoming an AI-augmented buyer, using technology to make more informed and efficient decisions.

The IAB’s 2026 forecast for media buyers paints a clear picture: success hinges on adaptability, data-driven decisions, and a willingness to embrace emerging technologies and channels. The focus on retail media, first-party data, CTV, and AI isn’t just theoretical. These are the pillars of effective campaign performance in the current digital advertising climate.
