How Is Digital Ad Spending Shifting Across Social Media Platforms?

January 24, 2025

In an industry constantly shaped by technological advancements and evolving user preferences, digital ad spending has demonstrated noticeable shifts across various social media platforms. The trends observed in the fourth quarter of 2024 highlight substantial changes and strategic investments among leading and emerging platforms alike. According to data from Tinuiti, there is a notable year-over-year increase in Meta’s ad spend by 15%, suggesting significant growth and competitive momentum. Meanwhile, TikTok has exhibited a contrasting trend with a sharp decline of 51 percentage points from the previous year, though it still managed an overall spend increase of 27%, reaching $4.8 billion in 2024.

The observed dichotomy in TikTok’s performance underscores the challenges and opportunities it faces, especially in the U.S. market, juxtaposed with its global footprint robustly expanding. Amid these shifts, the study identifies several key trends, including the competitive nature of digital advertising and the enhanced efficiency brought by AI-driven campaigns. By examining the digital ad expenditure patterns across platforms like Meta, TikTok, Amazon, and Walmart, alongside smaller yet important players like Pinterest and Snapchat, one observes a complex yet broadening strategy among marketers aiming to diversify their spending across multiple channels.

Meta’s Growth and the Competitive Landscape

Meta’s ad spending saw an upward trajectory in Q4 2024, with Facebook and Instagram being the main drivers. For the first time since Q3 2022, Facebook’s CPM (cost per thousand impressions) saw positive trends, with an 11% growth in ad spending noted in Q4 2024, up from 5% in Q3. This revival signals a renewed confidence among advertisers in Facebook’s potential to reach a broad audience effectively. Particularly, during the holiday season, Instagram experienced a significant leap with a 20% year-over-year increase, reinforcing its position as a vital platform for digital advertising.

The study also points out interesting spend allocation dynamics, showing that for every dollar spent on Meta, marketers allocated $0.19 to TikTok and Pinterest, with Snapchat closely trailing at $0.15. This spending pattern reflects marketers’ intent to distribute their ad budgets across various platforms, not merely sticking to the dominant leaders. Smaller platforms such as Pinterest and Snapchat receiving noticeable investments illustrate the diversification strategy that aims to capitalize on distinct audience segments and unique platform attributes. Ultimately, these investment trends indicate that while Meta remains a powerhouse in digital advertising, competitors are firming up their positions by attracting significant ad spend from a diverse array of marketers.

TikTok’s Challenges and Global Reach

TikTok’s experience in Q4 2024 showcases a complicated narrative, marked by a sharp decline from the previous year’s performance in the U.S., yet an overall ad spend increase globally by 27% amounting to $4.8 billion. This complexity signals that while TikTok is still grappling with hurdles in certain markets, its international appeal and adaptability continue to generate substantial growth. Its experience underscores the growing pains of an emerging platform striving to carve out a substantial market share amidst stiff competition and regulatory scrutiny in regions like the U.S.

Despite these challenges, the platform’s growing ad spend highlights the importance of its diversified influence. Marketers’ willingness to dedicate significant portions of their budget to TikTok reflects an acknowledgment of its powerful engagement potential, especially among younger demographics. This investment trend also underscores the value marketers place on TikTok’s unique content delivery and user engagement strategies, which continue to set it apart from other platforms. Such patterns suggest that TikTok’s future lies in balancing its strong global presence while addressing region-specific challenges to solidify its standing further.

Amazon and Walmart’s Digital Advertising Advancements

Amazon’s Demand-Side Platform (DSP) marked a significant leap in Q4 2024, with a 36% year-over-year increase driven partly by the introduction of Amazon Prime Video ads. This DSP growth underscores Amazon’s strategy of leveraging its extensive reach and integrated services to enhance its advertising portfolio. Consequently, DSP accounted for 32% of Amazon’s total ad investment, showcasing the potential held by the e-commerce giant in the digital ad space. High CPM rates associated with Amazon’s properties and partnerships with external publishers through Amazon Publisher Services further emphasized its rising influence in digital advertising.

Walmart’s Sponsored Products demonstrated the highest growth among its search ad formats in Q4 2024, with a 53% year-over-year increase. These Sponsored Products dominated Walmart’s total search ad spend, accounting for 88%, while Sponsored Brands and Sponsored Video each made up 6%. The observed growth points to Walmart’s strategic emphasis on enhancing its advertising reach and effectiveness by prioritizing essential products over diversifying formats. This focus underlines the significant competitive landscape within the digital ad realm, where both Amazon and Walmart strive to expand and optimize their advertising capabilities.

Broadening Strategy and AI-Driven Efficiency

In a field constantly influenced by technological innovation and shifting user preferences, digital ad spending has shown significant changes across various social media platforms. The Q4 2024 trends underscore notable shifts and strategic investments among both leading and emerging platforms. Data from Tinuiti reveals that Meta’s ad spend has risen noticeably by 15% year-over-year, indicating substantial growth and enhanced competitive edge. In contrast, TikTok experienced a sharp decline of 51 percentage points from the prior year, despite achieving a 27% increase in overall spend, totaling $4.8 billion in 2024.

TikTok’s performance highlights the challenges and opportunities in the U.S. market while maintaining strong global growth. Amid these changes, several key trends emerge, including the competitive nature of digital advertising and improved efficiency from AI-driven campaigns. Analyzing the ad spending patterns on platforms like Meta, TikTok, Amazon, and Walmart, alongside smaller yet significant players like Pinterest and Snapchat, reveals a multifaceted strategy. Marketers are increasingly diversifying their expenses across multiple channels to optimize reach and impact.
