Second quarter saw slowing ad spend on most platforms

Most U.S. digital ad platforms saw slowing ad spending last quarter, according to a new report from digital marketing agency Tinuiti.

Amazon Sponsored Products, Facebook, Google search and Instagram all saw lower spending growth year-over-year in Q2 2024 than a quarter earlier. YouTube was the only major platform that saw an increase. 

The video platform saw a 28% increase in ad spend last quarter, compared to 18% in Q1. This was in response to a 74% increase in impression volume. At the same time, those new impressions were relatively cheap, which pushed average CPM down 26% year-over-year in Q2, down from a 3% decline in the previous quarter, according to Tinuiti’s Q2 2024 Digital Ads Benchmark Report.

Investment in Meta properties rose by 10% year-over-year in Q2, down from a 16% increase in Q1. This deceleration is partly due to a tougher comparison with Q2 of the previous year, where spend growth surged from 0% in Q1 2023 to 9% in Q2 2023.

Facebook’s share of total Meta ad spend dropped compared to last Q2 but still accounted for 68% in Q2 2024, maintaining its dominance among Meta’s platforms. Instagram’s spend share increased from 29% last year to 32% this year, as its spend growth outpaced Facebook’s in Q2. Messenger and Audience Network continue to represent a small portion of total Meta ad spend for most advertisers.

In the second quarter, Instagram’s advertising spend growth rate cooled to 24% year-over-year, placing it second behind YouTube. This marks a shift from Q1, where Instagram led the pack, according to the report.

Across both Facebook and Instagram, AI-driven Advantage+ campaigns continue to be a major factor in retailer advertising expenditure. However, the share of spending to this format has slightly decreased since the peak holiday shopping season in Q4. This shift in ad format popularity and spending patterns reflects Meta’s ongoing efforts to optimize its advertising offerings across its platforms. 

Facebook’s CPM decreased by just 1% year-over-year in Q2 2024, the fifth consecutive quarter where the year-over-year CPM decline has lessened. The report said this is partly because of the increasing share of Facebook impressions from Reels videos and overlay ads, which are significantly cheaper than Feed placements, lowering the overall CPM for the platform.

Google

Google search advertisers increased their budgets by 14% year-over-year in Q2 2024, down from 17% growth in the previous, according to the report. Spending on Google shopping ads, including Performance Max and standard Shopping campaigns, rose by 16% year-over-year in Q2. In contrast, click growth for Google text ads remained weak in Q2, with a notable drop in click-through rates in May as Google introduced AI Overviews to all U.S. users.

Google’s search advertising landscape showed mixed results in Q2 2024. Advertiser spending on Google search ads increased by 14% year-over-year, a slight deceleration from the 17% growth observed in the previous quarter. This marks the fifth consecutive quarter of slowing click growth for Google’s search ads, with Q2 seeing only a 3% increase.

On the pricing front, advertisers experienced some relief as the cost-per-click (CPC) growth rate slowed to 12% year-over-year, following four quarters of accelerating CPC growth. Despite this overall slowdown, Google shopping ads remained a bright spot in the company’s search ad portfolio.

Notably, the growth in shopping ad spending over the past two quarters has been primarily driven by higher CPCs, indicating that advertisers are willing to pay more for these high-performing ad formats, the report found. 

Amazon

Amazon Sponsored Products spending growth decelerated more significantly in Q2 compared to Google search, reaching 8% year-over-year. However, sales generated through Sponsored Product ads performed better, increasing by 11% year-over-year for the quarter, resulting in improved return on investment for advertisers.

Amazon maintained its high share of Google shopping ad impressions from Q1 to Q2, reaching levels typically seen only during holiday seasons. This aggressive approach in 2024 follows Temu’s significant push to gain US market share in 2023, which included becoming a major buyer of Google shopping ads. Interestingly, the report found Amazon reduced its presence in Google’s text ad auctions this year, suggesting a potential reallocation of spending between ad formats.

Emerging platforms

Several emerging advertising platforms experienced significant growth last quarter. Walmart Sponsored Products’ advertisers boosted their spending by 45% year-over-year, the fifth consecutive quarter of over 30% growth. TikTok saw a 10% year-over-year increase in ad spend, while Snapchat and Pinterest demonstrated more robust growth at 26% and 22% respectively.
