2025 Advertising Recap: Shifts in Execution, Enduring Laws of Brand Growth

As we wrap up 2025, it's clear this has been a pivotal year for advertising. The industry has undergone significant tactical shifts: from the rise of AI-powered automation to the mainstreaming of creator partnerships and the evolution beyond traditional SEO toward sophisticated geo-targeting.

Yet beneath all the operational changes, the fundamental laws of brand growth remain as solid as ever.

While the methods have evolved dramatically, the marketing science Byron Sharp documented in How Brands Grow hasn't budged an inch. Let's break down what actually changed this year versus what stayed remarkably consistent.

The Big Tactical Shifts of 2025

AI and Automation Became Infrastructure, Not Innovation

The biggest shift this year was AI moving from experimental to essential. What started as Smart Bidding experiments and automated ad placement testing has become the backbone of how we buy media.

According to industry reports, automation adoption increased 17% since mid-2024, with 86% of advertisers now using some form of automated campaign management.

But here's what's interesting: this shift revealed gaps, not just opportunities. The same research showed that 86% of advertisers still struggle with synchronization between creative and media processes.

Technology solved the optimization problem but exposed the collaboration problem. The agencies winning in 2025 are those building hybrid teams where humans handle strategy and storytelling while AI manages the tactical execution.

The lesson? Automation amplifies good strategy and exposes bad strategy faster than ever.

From SEO-First to GEO-Smart Media Buying

Remember when "just optimize for SEO" was the digital strategy? Those days feel ancient now. In 2025, we've seen the rise of sophisticated geo-targeting that goes far beyond zip codes.

Streaming platforms are using automatic content recognition (ACR) data to serve ads based on what someone's watching, when they're watching, and crucially: where they're watching from.

This shift means media buyers can now target someone watching a cooking show in their kitchen at 6 p.m. with grocery ads, or catch a commuter streaming content on their phone with location-relevant retail offers.

It's not about ranking higher in search results anymore. It's about being in the right place at exactly the right moment.

The Creator Economy Went Professional

2025 marked the year creator partnerships moved from influencer marketing afterthought to strategic media channel. Cannes even renamed their category from "Social & Influencer" to "Social & Creator." This is a signal that creators are now viewed as media partners, not just spokespeople.

The smartest brands stopped asking creators to read scripts and started building campaigns around their authentic voices and communities. Instead of casting a TikTok star to deliver your message, successful brands are co-creating content that feels native to both the creator's audience and the brand's goals.

This shift is particularly powerful because creators solve two problems simultaneously: they provide reach in an attention-fragmented world, and they offer authenticity in an increasingly skeptical media environment.

Shoppable Everything Became the Standard

Social commerce matured rapidly in 2025. With 62% of Gen Z consumers shopping through social media platforms, shoppable ads moved from novelty to necessity. TikTok Shop, Instagram Shopping, and Pinterest's product pins became genuine sales channels, not just awareness drivers.

The tactical shift here is huge for media buyers. Instead of optimizing for clicks or video views, we're now optimizing for actual purchases within the platform itself. This changes everything about how we structure campaigns, allocate budgets, and measure success.

AR/VR Crossed the Mainstream Threshold

Augmented reality finally found its practical application in advertising. Nike's AR integration letting customers visualize products in their space, beauty brands enabling virtual try-ons, and furniture retailers allowing room visualization all became standard rather than experimental.

The key insight: AR succeeded when it solved real problems (reducing return rates, increasing purchase confidence) rather than just providing cool experiences.

The Enduring Laws That Never Wavered

Mental Availability Still Trumps Everything

Byron Sharp's principle of mental availability remained the most predictive factor of brand growth in 2025, despite all the technological innovation,. Brands that stayed visible and built broad reach remained distinctive and continued to outperform those chasing narrow audiences with sophisticated targeting.

The most successful campaigns this year combined new tactical capabilities (AI optimization, creator partnerships, geo-targeting) with the timeless goal of maximizing mental availability across the broadest possible audience.

Attention Remains the Scarcest Resource

All the automation and optimization in the world can't solve the fundamental challenge: human attention is finite and increasingly fragmented. The platforms growing fastest in 2025—Connected TV (55% of marketers increasing spend), social media (68% increasing spend)—are those that naturally command attention, not necessarily those with the best technology.

This explains why the most effective campaigns combined sophisticated targeting with compelling creative that actually stops the scroll, pauses the stream, or interrupts the feed in meaningful ways.

Authenticity Can't Be Automated

Authenticity became more valuable as advertising became more automated. Gen Z and Gen Alpha consumers continued prioritizing brands that demonstrate genuine values over those with slick targeting capabilities.

The brands that thrived in 2025 were those that used new tools to amplify authentic messages, not those that tried to use technology as a substitute for genuine brand purpose.

Mark Ritson's emphasis on distinctive brand assets proved more relevant than ever—in an AI-optimized world, having clear, recognizable brand elements becomes the key differentiator.

Measurement Challenges Persist Despite Better Data

Even with more sophisticated attribution modeling and AI-powered analytics, the fundamental measurement challenges documented by Les Binet and Peter Field remain.

The relationship between short-term activation and long-term brand building hasn't changed, even if our ability to track individual touchpoints has improved.

The smartest marketers in 2025 used better data to inform the same balanced approach: roughly 60% long-term brand building, 40% short-term activation. Technology improved measurement precision but didn't change the optimal balance.

Talent Beats Technology Every Time

As media buying tools became commoditized, human judgment became more valuable, not less. The agencies and brands winning in 2025 were those that attracted strategic thinkers who could navigate cultural nuance, ethical considerations, and platform dynamics.

In an industry where everyone has access to similar AI tools and automation platforms, the differentiator becomes who can think most strategically about when and how to use them.

Why the Fundamentals Endure

The reason marketing science principles remain constant while tactics evolve rapidly is simple: human psychology doesn't change, but human behavior does.

People still need to be aware of your brand before they can buy it. They still make decisions based on mental shortcuts and emotional responses. They still respond to social proof and distinctive assets. They still have finite attention and cognitive processing capacity.

What changes is how we reach them, where we find them, and what tools we use to deliver messages. In 2025, we could use AI to optimize delivery, creators to provide authenticity, AR to enable trial, and geo-targeting to improve relevance. But we were still fundamentally trying to build mental availability, create distinctive memories, and drive both awareness and activation.

The brands that succeeded in 2025 were those that embraced new tactical capabilities in service of timeless strategic principles. They used automation to buy media more efficiently, not to replace strategic thinking. They partnered with creators to build authentic connections, not to chase trending content formats. They adopted AR and social commerce to remove friction from the purchase process, not to distract from clear value propositions.

Looking Forward: Tactics Change, Science Endures

Expect the tactical evolution to accelerate in 2026. New platforms will emerge, AI capabilities will expand, and privacy regulations will continue reshaping how we collect and use data.

But the fundamental job of building brands—creating mental availability through broad reach and distinctive messaging—won't change.

The winners will be those who stay curious about new tactics while remaining grounded in proven principles. They'll use tomorrow's tools to solve today's problems: breaking through the noise, building genuine connections, and creating memories that drive choice behavior.
