Gane's interests in what the Index measures, and the suppliers that are also measured here.
Gane sells marketing software, assessments and execution services. It sells software in eight of the categories this area covers: AI marketing agents, AI visibility and answer engine tracking tools, Attribution and marketing mix modeling, Competitive intelligence tools, Content marketing platforms, Email marketing platforms, Marketing automation and campaign management and SEO and content optimization platforms. Each is collected, scored and published by the same method as every other category, and its pages carry the conflict line.
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 four of them are products that a model named in the categories they belong to: Vercel (named in Landing pages), Neon (named in Warehouse & ETL), Lemon Squeezy (ranked in Billing and Affiliate), Plausible (named in Product analytics and Session replay). 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.
