Google has held the top spot in digital advertising since the industry was born. That ends in 2026. eMarketer projects Meta will generate $243.46 billion in ad revenue this year, edging past Google’s $239.54 billion. Not because Meta grew its user base faster. Because of Advantage+.
The gap is small. The trajectory is not.
In 2025, Google earned $214 billion in ad revenue to Meta’s $196 billion - an $18 billion gap. In 2026, that reverses. Meta grows 24.1%; Google grows 11.9%. If those rates hold, the distance between the two will widen significantly into 2027.
Add Amazon ($82 billion, 9% global market share), and three platforms now control 62.3% of all worldwide digital ad spending (eMarketer, 2026). The remaining 37.7% is split among every other platform, publisher, and ad network in existence. This is an increasingly winner-take-most market.
Why Advantage+ is the real driver
Meta’s user base didn’t surge in 2025-2026. What changed is Advantage+.
Advantage+ ran at a $20 billion annualized pace in March 2025. By October 2025, that hit $60 billion - 3x growth in seven months (Tech-ish, 2026). Instagram Reels separately crossed $50 billion annualized, exceeding all of YouTube’s entire 2024 ad revenue ($36 billion).
According to eMarketer analyst Zach Goldner, Advantage+ is “unlocking more value across Meta’s entire ecosystem” by applying AI across all three campaign layers: targeting, bidding, and creative. Google’s Performance Max does something similar - but Meta’s advantage lies in social behavioral data that search intent cannot replicate.
The performance case is strong: e-commerce brands using Meta AI automation report 67% higher ROAS than manual management. Brands running 20+ new creatives per month see 65% higher ROAS than those testing fewer than 10. FULLBEAUTY Brands reported a 45% ROAS lift after switching to Advantage+.
A tension worth noting: Meta reports an average +22% ROAS improvement, but independent analysis suggests the median incremental gain is closer to parity. Real benefits are concentrated at the top quartile - brands that invest seriously in creative quality and testing velocity. Advantage+ isn’t a universal unlock. It rewards the right operating model.
Vietnam: different ranking, same convergence pressure
Vietnam’s digital advertising market tells a different story - for now. Google holds 28.4% market share versus Meta’s 19.2% (Digital in Asia, 2026). The reason is structural: Google controls 90%+ of search in Vietnam, making Google Search non-negotiable for any brand that needs discoverability.
But a third player is disrupting both: TikTok has doubled its market share to 8.7%, with Retail Media from TikTok Shop and Shopee eating into both social and performance budgets.
For Vietnamese marketers, the global Meta vs Google reversal is a leading indicator, not a current reality. Google Search stays dominant. The competitive battle is in social and performance, where Advantage+ gives Meta a meaningful edge over any manual campaign approach - including TikTok’s less mature automation stack.
Gartner projects AI automation in marketing to grow from 16% today to 36% by 2028. Vietnamese marketing teams are early in that curve, but the direction is set.
How the marketer’s job changes from here
The most important shift isn’t Meta vs Google. It’s algorithm vs manual.
Advantage+ performs best when advertisers abandon manual audience segmentation. Broad targeting plus high creative variation beats “female, 25-40, interested in fashion, living in Ho Chi Minh City.” That’s the operating principle - and it directly conflicts with how most marketing teams, especially agencies, currently frame their expertise and value.
Creative testing velocity is the strongest performance predictor in Advantage+ campaigns. By late 2026, Meta plans to roll out fully automated ad creation: provide a goal, a budget, and a product image - AI builds the rest. That’s not a forecast. It’s a published roadmap.
The brands that win aren’t the ones with the most granular targeting. They’re the ones that can produce and test the most creative, the fastest.
NateCue's Take
Most marketing teams - in Vietnam and globally - still treat detailed audience segmentation as professional craft. Advantage+ runs on the opposite premise: broad targeting plus high creative velocity beats any targeting configuration. The uncomfortable trade-off is real: better performance in exchange for less transparency into how the algorithm works. Agencies that adapt to a "creative producer + algorithm manager" model will win. Those clinging to "audience targeting specialist" positioning will see the data quietly make their case for them. Looking at Advantage+'s jump from $20B to $60B in seven months, this is moving faster than most teams realize.
