Google Search revenues surged past expectations with ad growth 5.4% above forecast, while Meta overperformed with ad revenue of $55bn against a projected $54.1bn – 2.3% ahead of predictions. However, YouTube’s $72m ad revenue shortfall reveals engagement-to-revenue conversion gap.
So finds the latest data from WARC Media’s 2026 online ad market tracking, which is derived from a proprietary neural network of over two million data points and, says the organisation, offers a clear view of how the digital ad market is developing across this year.
Drilling into the data, WARC finds that Google was the standout performer during the quarter, with ad revenue up 19.1% to $60.4bn, a marked 5.4% above the benchmark of +13.7%. Clearly traditional paid search remains resilient and Google’s parent, Alphabet, is arguing with some confidence that AI is improving engagement rather than cannibalising it.
Indeed, CEO Sundar Pichai heralded that AI is “illuminating every aspect of the business” and that products such as AI Overviews and AI Mode are now bringing users back to search more often. While progress is evident, the quarter revealed uneven performance across Alphabet’s advertising portfolio, with AI-driven gains not distributed equally among all business units.
YouTube’s reported ad revenue of approximately $9.98bn came in around $72m below the forecast value of $10.05bn, suggesting that strong engagement is still not converting into revenue quite as elegantly as executives would prefer, however.
Short-form video continues to attract attention at scale, but monetisation still appears to lag the consumption curve: this is now the second consecutive quarter in which YouTube has fallen short of WARC’s forecast expectations, though the gap was far wider last quarter.
Google’s Display Network continues to decline in step with a moribund open web. Here, ad revenue dipped 3.9% compared to a forecast fall of 2.3% – this suggests Alphabet’s AI ambitions may be creating trade-offs in certain areas potentially at the expense of others.
Meta was an overperformer this quarter, with ad revenue of $55.0bn against a forecast of $54.1bn – 2.3pp ahead of WARC’s benchmark. Better targeting, more automated buying and faster optimisation appear to be helping Meta convert its AI infrastructure into measurable performance, rather than merely an expensive slide in an investor deck.
Management commentary reinforces this interpretation. CFO Susan Li reported that ranking improvements on Instagram drove a 10% lift in time spent with Reels in Q1, while Mark Zuckerberg pointed to strong trends across Meta’s apps and all-time high engagement around video content.
Overall, the results suggest Meta is increasingly effective at capturing user attention, selling it, monetising it, and commanding premium rates in the process.
Given the combined scale of these three players – accounting for 58% of all ad investment globally excluding China – they provide a useful yardstick for the industry at large. Taken together, the quarter suggests that advertisers are continuing to reward platforms that combine scale, first-party data and increasingly competent automation.
