Alphabet Inc. GOOGL Moat

Key data

The moat

Google's search moat is a habit loop with a data flywheel underneath. People search on Google because it works, it works partly because so many people search on it, and the default placements on browsers and phones make sure the first search happens. Advertisers follow the users, and no other property offers intent at that scale.

Cloud is a different moat entirely and a newer one. Enterprises that build on a cloud platform embed themselves in its identity, data and machine learning services, and the switching cost compounds with every workload added.

What the two produce together is the widest set of disclosed sequences here.

Widening or narrowing

Both engines accelerated through the period when the consensus expected search to erode.

Search revenue growth roughly doubled from 10% to 19%, which is the opposite of what four years of commentary about artificial intelligence replacing search would predict. Acquisition costs fell as a share of advertising revenue from 20.5% to 19.8%, meaning Google paid slightly less for each dollar of traffic while collecting more.

Cloud is the stronger sequence: growth rose in every quarter but one and margin rose in every single quarter, from 17.5% to 35.6%. A business growing 82% while doubling its margin is not competing on price. It is being paid more for the same capacity, which is what happens when demand exceeds what the industry can build.

The overrated case. Independent measurement shows Google's global search share at roughly 89.5 to 90.1%, down from 92.6% in 2022. The erosion is concentrated on desktop, at 79.1%, while mobile sits at 95.5%. Two and a half points over four years is slow, and it is one direction. The desktop and mobile split matters: the erosion is happening where a user can type a different address, and not happening where the search box is built into the phone.

On profit pool, Google takes the advertiser's payment for intent that the user supplied for free, and keeps roughly eighty cents of every advertising dollar after distribution costs. That is close to the widest slice in commerce.

The moat is widening in both segments.
