Google Search is growing faster than YouTube.
For three consecutive quarters, Search & other ad revenue has outgrown YouTube Ads.
YouTube has long been Alphabet’s growth darling, often outgrowing Search.
It made sense: a newer product, huge ad inventory, lower monetisation.
Not anymore.
And this is mostly because of AI.
AI Overviews unlocked completely new, incremental ad placements within Google Search. Ads can appear within and below AI Overviews with one placement not excluding the other.
Then there are ads in AI Mode too.
Meanwhile, YouTube faces a saturation problem.
I remember when ads were sporadic.
Now virtually every video has one or more: two pre-rolls, often followed by mid-rolls.
Sometimes I use a VPN to browse from the US.
The ad pressure there is insane.
Not by coincidence, Performance Max increasingly favours Search over YouTube.
When I started testing it in 2021, Search accounted for less than half of impressions and clicks. The rest came mostly from Display and YouTube.
Today, our campaigns serve almost exclusively on Search.
I’m not sure what Google’s strategy is.
On one hand, YouTube’s ad inventory is clearly saturated and growth is slowing.
On the other, “Subscriptions, platforms & devices”, which includes YouTube Premium, keeps growing at the same or a higher pace than Search.
In 2025, subscriptions accounted for 33% of YouTube total revenue.
(In Q4 2025, Sundar Pichai said YouTube had surpassed $60B in annual revenue, of which around $40B from ads).
I guess the subscription share will grow further.
I wouldn’t be surprised if users frustrated with YouTube ads were increasingly switching to Premium, moving revenue from one bucket to another.
Personally, I’m a heavy YouTube user. I have been since 2007, I love it.
Living in a small market like Switzerland, I’m still okay with the current number of ads. But for how much longer?
Are ads or subscriptions more profitable?
If anyone in the comments knows the answer, I’d be very interested to discuss it further!
