IAB Spain on June 30, 2026 published Marcas y Atencion Social 2026: datos, tendencias y aprendizajes, a report built on 18.9 billion views and 159 million interactions across 1,163 Spanish brands, and the headline finding cuts against the industry's usual instinct to chase reach. Views rose 17 percent year over year, yet interactions across the same brand set fell 16 percent, according to IAB Spain. Content saturation, meanwhile, multiplied by 5.2 times and channel fragmentation grew 73 percent, the association reported. KFC topped the resulting brand ranking, Red Bull followed in second place, and the study frames the gap between visibility and response as the defining tension for Spanish marketers heading into the second half of 2026.

The report was produced by IAB Spain, the Spanish digital advertising and marketing trade association, in partnership with Epsilon Technologies, a Publicis Groupe-owned data and identity company. It draws on a panel called Panel SAI 1000 Marcas Espana, which despite its name tracked 1,163 Spanish multi-category brands across 3,777 social profiles on Instagram, Facebook, TikTok, X, YouTube, and LinkedIn, analyzing 159,000 individual posts between January and May 2026 and comparing the results against the same period the year before.

A widening gap between reach and response

The numbers at the center of the report describe two curves moving in opposite directions. Total Consumer Digital Touch Points, IAB Spain's aggregate measure of every contact point across the tracked digital ecosystems, reached 19.16 billion, up 16.4 percent versus the prior year. Views specifically climbed to 18.9 billion, a gain of 16.98 percent. Interactions, however, dropped to 159 million, down 15.99 percent, and interactions occurring on external channels, meaning conversation generated by hashtags and user mentions rather than brand-owned posts, fell even further, down 17.73 percent to 86.8 million.

Only one indicator in the core dataset moved firmly in the same direction as views: follower growth. Incremental followers rose 59 percent year over year to 18.4 million, according to the report. Audiences are subscribing to brand accounts at a faster clip than they are actually responding to what those accounts post, which is precisely the disconnect the report's authors set out to measure.

IAB Spain frames the pattern in stark terms in its own summary of the findings, arguing that visibility grows while attention must be earned. That framing gives the report its methodological backbone: two indices, called DAI (Digital Attention Index) and SAI (Social Attention Index), designed to move measurement away from raw exposure and toward a brand's actual share of audience response relative to competitors in its category.

How the indices are built

DAI is the broader of the two constructs. It combines eight input categories, namely social media, social listening, search, influencers, web traffic, app traffic, public relations, and point-of-sale experience, then multiplies the sum by what the report calls an EDI factor before arriving at a composite score. SAI is the narrower, social-specific version, expressed by IAB Spain as brand share of the combined total of interactions, external mentions, views, and social listening volume, measured against every other brand in the same competitive set.

Applying SAI to the panel produced a ranked list. Red Bull recorded the highest CDTP-based share at 3.56 percent, but KFC led on the SAI composite at 3.10 percent once the interaction and external-mention weighting was applied, followed by Mahou at 2.61 percent, Druni at 2.26 percent, and Lidl at 2.13 percent. The remainder of the top twenty included Kiko, Carrefour, Burger King, Dia, El Corte Ingles, Zara, Samsung, McDonald's, Estrella Galicia, Iberdrola, IKEA, Primor, Futbol Emotion, Sephora, and Pantene, though each individual share sat below 1.7 percent, illustrating how thinly interaction volume is spread once nearly 1,200 brands compete for it.

Retail and FMCG pull almost 60 percent of the total

Sector-level results show a market skewed heavily toward two categories. Retail brands captured 34.5 percent of total SAI share, and fast-moving consumer goods brands took 24.9 percent, meaning the two sectors combined absorbed close to 60 percent of all measured social attention in Spain during the study window. Energy followed at 3.5 percent, automotive at 3.4 percent, fashion at 3.1 percent, banking at 2.1 percent, insurance at 1.8 percent, telecommunications at 1.3 percent, and airlines at 0.6 percent.

According to IAB Spain's own account of the report, retail and FMCG together combine frequency, cultural presence, and a persistent capacity to generate conversation through content, creators, campaigns, and experiences, which explains why the two categories dominate the ranking so completely. Within retail, the top-ranked brands by CDTP were Lidl at 564.3 million, Druni at 484.7 million, Carrefour at 281.6 million, and KFC at 175.4 million; within energy, Iberdrola led with 284.5 million CDTPs, ahead of Repsol at 162 million.

Interaction quality varies sharply by platform

Perhaps the most operationally useful section of the report breaks interaction share down by individual platform rather than treating social media as a single undifferentiated channel, and the resulting picture argues against a one-size-fits-all content strategy.

Instagram concentrated 69.6 percent of interactions across the entire panel, cementing its position as the primary engagement surface for Spanish brands. Within Instagram specifically, KIKO led interaction share at 5.55 percent, followed by Zara at 5.48 percent and KFC at 5.20 percent, with Druni fourth at 4.09 percent. Reels emerged as the standout format inside Instagram: photo posts generated 2,721.75 average interactions per post against 2,320.86 for Reels and only 1,243.29 for carousels, though Reels' combination of reach and relative efficiency, according to the report, makes it the most cost-effective format for scaling results.

TikTok told a different story. The platform accounted for 39.93 percent of total views across the panel, positioning it as the discovery layer of the ecosystem rather than its conversation layer. KFC's TikTok interaction share reached 14.31 percent, more than four points ahead of Red Bull in second place at 10.56 percent, and Lidl in third at 5.53 percent. A separate chart tracking KFC's TikTok performance across five years shows the brand moving from a 0.9 percent share and 15th-place ranking in 2021 to a number-one position by 2022, a rank it has held every year since, closing 2025 at 19.1 percent share on the platform.

X (formerly Twitter) showed the most extreme concentration of any platform measured. KFC alone accounted for 60.50 percent of total interaction share on X across the tracked brand set, with Lidl a distant second at 14.36 percent and GAME third at 2.87 percent. No other platform in the study produced a single-brand share anywhere close to that level, suggesting that a small number of accounts, rather than the platform's brand population broadly, are driving nearly all measurable engagement there.

Collaboration outperforms activity volume

One of the report's more counterintuitive findings concerns the relationship between how much content a brand produces in partnership with outside creators and how much interaction that content actually returns. Collaborative content, meaning posts made jointly with influencers, celebrities, or sponsorship partners, represented only 15.4 percent of total brand activity across the panel but generated 32 percent of all interactions, and a similar pattern held for collaborative activity more broadly, where 15.4 percent of posting volume produced 32 percent of engagement.

IAB Spain's public summary of the findings describes collaboration as having become an accelerator of relevance, combining the credibility that creators and celebrities bring, the natural integration of products inside existing content formats, and access to communities that already exist around podcasts and sponsorship properties. The report groups successful collaboration strategies into six recurring types: celebrity partnerships, influencer-product integrations, sponsorships, recipe or usage-demonstration content, co-branding, and podcast appearances.

Case studies behind the numbers

The report includes eight detailed campaign case studies, each scored by the share of a brand's total interactions the campaign generated. McDonald's, in partnership with streetwear brand EME Studios, launched a limited hoodie of 2,600 units during March 2026, supported by a pop-up conversion of EME Studios' Fuencarral Street flagship store in Madrid into a themed McDonald's restaurant on March 21 and 22, plus QR-code patches redeemable for free products through the MyMcDonald's loyalty app. The campaign generated 161,604 interactions and 27.5 million views across 15 posts, representing 34 percent of McDonald's total interactions for the period, the largest share of any single case study in the report.

Samsung's collaboration with footballer Alexia Putellas, tied to the Galaxy Z Fold7 and Galaxy Watch8, used AI tools including Gemini and a feature the report calls Nano Banana to recreate career moments that were never actually photographed. Despite running just five posts across a single month, the campaign accounted for 22 percent of Samsung's total interactions, generating 10,947 interactions and 97.4 million views. Alpro's Matcha Coconut launch, combining influencer Belen Esteban with an in-person Matcha Studio experiential space, produced 240,050 interactions and 53.4 million views across 29 posts over two months, representing 31 percent of Alpro's total interaction volume. Lidl's tapas voting contest with content platform SpainSays and chef Daniel Valls generated a comparatively modest 16,386 interactions from 10 posts, but the report highlights its serialized format, in which each weekly episode functions as a self-contained piece of content while still building toward a cumulative narrative, as a structural template other brands could adapt.

What the report recommends for the rest of 2026

IAB Spain's conclusions describe a shift the report calls moving from Always On to Always Drop, meaning a move away from continuous, high-frequency posting and toward concentrated, memorable moments built around cultural relevance. The report proposes five components it considers necessary for a drop-style campaign to succeed: activating prescription through collaboration with current influencers, adopting realism and closeness rather than heavily polished advertising codes, ensuring omnichannel presence connecting offline and online touchpoints, building genuine experiential elements so a campaign is lived rather than only watched, and maintaining consistency through two to three major drops per year rather than one-off stunts.

The report closes with ten numbered conclusions, several of which reinforce points made earlier in the data. Among them: Instagram builds brand affinity while TikTok builds community, meaning each platform performs a distinct function inside the funnel rather than serving as interchangeable inventory; the Reel format remains the single largest driver of visibility for brands able to combine reach with humanized, approachable content; and audiences, in the report's own phrasing, are not saturated so much as bored, meaning the volume of impressions is not the constraint on performance so much as the sameness of what fills them.

Why this matters for marketers

The Spanish findings sit inside a broader European measurement conversation that Spain's CTV market hits 95% penetration - but ads still face a trust gap and IAB Spain's first SSP guide exposes the 41% working media problem have already documented this year: Spanish advertisers are consistently finding that raw exposure metrics, whether views, impressions, or programmatic bid volume, mask a much smaller pool of genuinely productive engagement underneath. The SSP guide found only 41 percent of programmatic spend reaches measurable, viewable impressions; this social attention report finds a parallel gap between how many people see a brand's content and how many actually respond to it.

The report also lands weeks after IAB Spain's own annual social media study, which found that Spain's social media users jump to 7.2 platforms - but 42% quit at least one, a pattern of rising platform adoption paired with rising abandonment that helps explain why interaction rates might fall even as follower counts and views climb. Users are spreading their attention across more surfaces while committing less of it to any single one, which is consistent with a market where content saturation has multiplied by 5.2 times, as this report separately found.

For agencies and in-house marketing teams operating in Spain, the practical takeaway is less about any individual brand's ranking and more about measurement discipline. A campaign generating millions of views but a shrinking interaction rate is not, on this data, a campaign in decline; it may simply be competing in a market where views have become structurally easier to generate than genuine response. Brands such as KFC, which posted the highest SAI share alongside the most extreme concentration of X interactions in the panel, and McDonald's, whose EME Studios collaboration produced over a third of the brand's total interactions from a single limited-run campaign, offer evidence that concentrated, creator-involved, culturally timed activity outperforms steady-state posting on the metric that IAB Spain argues actually matters: whether anyone responds.
