3 Sept 2026 Twelve weeks of measuring Google, and the four numbers that came out
We ran 4,185 queries through Google once a week for 12 weeks. Here is what held steady and what did not.
27 Aug 2026 Google cites what it does not rank
38.8% of AI Overview citations point at domains absent from the ten results below them.
20 Aug 2026 The same query in ten countries shares about half its results
Run an identical query from nine other countries and roughly half the domains change.
13 Aug 2026 Absent, not null: a response contract worth copying
The difference between a missing key and a null value is the difference between a clean integration and a 3am page.
6 Aug 2026 How to build a query corpus worth measuring
A measurement is only as good as the list it runs on. Here is how ours is built, and why it is generated rather than curated.
30 Jul 2026 Nine SERP APIs, one response body: what actually differs
Field names, block coverage, vertical count and metering policy — in roughly that order of how much trouble they cause.
23 Jul 2026 Pagination without an upper bound, and why page 40 matters
Most search APIs quietly stop somewhere around page ten. The work that needs page forty is the work worth doing.
16 Jul 2026 Why we publish our own data instead of describing it
Every search API claims to be accurate and comprehensive. None of them shows you the results. So we show ours.
