Platform Evolution and Media Consumption Shifts

The digital media landscape in the UK continues to fragment and evolve, presenting both challenges and opportunities for advertisers.

TikTok's Continued Rise

TikTok has firmly established itself as a major player in the UK advertising ecosystem, with user penetration now reaching 42% of the adult population. The platform is particularly dominant among younger demographics:

  • 73% of UK users aged 16-24 use TikTok weekly
  • Average daily time spent on TikTok has increased to 67 minutes
  • Ad spend on the platform is projected to grow by 32% in 2024

Brands that have previously hesitated to invest in TikTok are now developing dedicated strategies for the platform, recognizing its role in cultural conversations and commerce.

Connected TV Acceleration

Connected TV (CTV) advertising is experiencing rapid growth in the UK market, with spending projected to increase by 24% in 2024. Several factors are driving this trend:

  • 84% of UK households now have at least one connected TV device
  • Streaming services account for 41% of TV viewing time among 16-34 year-olds
  • Major broadcasters like BBC, ITV, and Channel 4 have invested heavily in their streaming platforms
  • Improvements in targeting and measurement capabilities are attracting performance-oriented advertisers

The shift toward CTV represents a significant opportunity for advertisers to combine the targeting precision of digital with the impact and viewability of traditional television.

Retail Media Networks

One of the fastest-growing segments in the UK digital advertising landscape is retail media networks. Major retailers including Tesco, Sainsbury's, Boots, and Amazon are developing sophisticated advertising platforms that leverage their first-party customer data.

Retail media ad spend in the UK is expected to grow by 28% to reach £2.3 billion in 2024, driven by:

  • Increasing pressure on brands to demonstrate ROAS in the current economic climate
  • The ability to connect advertising directly to purchase data
  • Growing sophistication of targeting and measurement capabilities
  • The strategic value of advertising at the point of purchase

"Retail media has quickly evolved from an experimental channel to a core component of our digital strategy. The ability to target consumers based on actual purchase behavior and measure direct sales impact has transformed how we allocate our digital media budget."

Privacy Evolution and Identity Solutions

The privacy landscape continues to transform digital advertising in the UK, with both regulatory and technological changes reshaping targeting and measurement capabilities.

Post-Cookie Strategies

With Google's deprecation of third-party cookies in Chrome now proceeding (albeit gradually), UK advertisers are accelerating their adoption of alternative targeting approaches:

  • First-party data strategies: 72% of UK advertisers report increasing investment in their first-party data capabilities
  • Contextual renaissance: Contextual targeting solutions have seen a 47% increase in adoption
  • Privacy sandboxes: Google's Privacy Sandbox and similar solutions are being tested by 38% of major UK advertisers
  • Clean rooms: Data clean room usage has increased by 86% year-over-year

The most successful organizations are adopting a portfolio approach, developing capabilities across multiple identity solutions rather than relying on a single replacement for cookies.

UK Regulatory Developments

The UK's post-Brexit regulatory approach to data privacy continues to evolve, creating both challenges and opportunities for advertisers:

  • The Data Protection and Digital Information Bill is advancing through Parliament, potentially creating more flexibility compared to GDPR
  • The Information Commissioner's Office (ICO) has issued updated guidance on consent mechanisms for digital advertising
  • The Online Safety Act is driving changes in platform policies and moderation practices
  • The Digital Markets, Competition and Consumers Bill will introduce new rules for major digital platforms

UK advertisers need to stay vigilant regarding these regulatory developments, as they may create both compliance requirements and strategic opportunities in how data can be utilized.

Creative and Format Trends

Beyond the structural changes in the market, several creative and format trends are shaping effective advertising approaches in the UK.

Short-Form Video Evolution

While short-form video remains dominant, its execution is evolving:

  • The average length of high-performing TikTok ads has decreased from 21 seconds to 17 seconds
  • "Hook" time has compressed further, with successful ads capturing attention in under 1.5 seconds
  • User-generated content (UGC) aesthetics continue to outperform highly polished content in many categories
  • Vertical video has become the default format across nearly all platforms

Brands achieving the greatest success are creating platform-specific content rather than repurposing creative across different environments.

Audio Renaissance

Digital audio advertising is experiencing significant growth in the UK market:

  • Podcast advertising spend has increased by 31% year-over-year
  • Dynamic audio creative optimization is being adopted by 42% more advertisers
  • Voice search optimization is becoming a priority for SEO strategies
  • Digital radio and streaming music platforms are seeing increased ad investment

The intimacy of the audio format and its ability to reach consumers during screenless moments makes it an increasingly valuable component of integrated campaigns.

AI-Generated and AI-Enhanced Creative

Artificial intelligence is transforming creative production and optimization:

  • 63% of UK advertisers report using AI tools for creative ideation or production
  • Dynamic creative optimization (DCO) using AI has increased by 41%
  • AI-powered testing platforms are enabling much more rapid creative iteration
  • Generative AI is being used to personalize creative elements at scale

  • Budget allocations are shifting toward lower-funnel activities
  • Measurement frameworks are evolving to better capture full-funnel impact
