Gane's interests in what the Index measures, and the suppliers that are also measured here.
Gane sells marketing software, assessments and execution services. No product of its falls in a category this area covers.
The Index's pages are on Gane's own domain. A citation of an Index page is never counted as Gane's own site, in any figure about Gane here or in Gane's product.
The 5% check of each edition's labels uses Claude Opus 5, made by Anthropic, one of the labs measured here.
The index is also a customer. The services it runs on are listed on the privacy page, and three of them are products that a model named in the categories they belong to: Vercel (named in LLM gateways and Managed databases), Neon (ranked in Managed databases), Lemon Squeezy (named in Identity verification). Being paid by the index buys a vendor nothing in it. Those labels came from the same prompts, the same models and the same judge as every other label, and they are published unmodified. A supplier gets no tag, no preview and no say. It is written down here because a reader who worked it out alone would be right to ask why it was not.
Each year this page lists every conflict category, every change to these rules and every correction made after a vendor's complaint.
