Cited-source analysis
The leading cited domains were mostly specialist AI visibility sites rather than the largest SEO publishers. A domain is counted at most once per answer.
Why register it first
AI answers vary by provider, model, search result, and time. Publishing the protocol first creates an auditable record of what will be asked, what counts as an eligible answer, and how each metric will be calculated.
The published results keep answer coverage beside every headline number. Four exact-string collisions found during manual review were excluded with their question, provider, and rationale preserved in the adjudication file.
Study design
The first edition focuses on software sold for AI visibility, AEO, GEO, or LLM SEO. The frozen 25-product cohort includes only products with a public first-party page offering measurement, monitoring, benchmarking, or optimization of visibility, mentions, citations, or positioning in AI-generated answers. Inclusion is not an endorsement.
The cohort, question text, locale, model IDs, matching rules, and scoring version are downloadable before any counted answer collection.
An answer is score-eligible only when the provider call succeeds and returns valid web sources. Exclusions remain visible in coverage.
Publish brand-level metrics, provider splits, cited-domain counts, answer-level evidence where permitted, and machine-readable CSV files.
Frozen question bank
Discovery prompts do not name a cohort brand. Five diagnostic templates are included in the download for qualitative product checks but will not enter the ranking metrics.

Study questions
It is a public study of which AI visibility, AEO, GEO, and LLM SEO software brands appear in web-grounded answers to a frozen set of buyer questions. The protocol is published before collection so the questions and headline metrics cannot be changed to fit the results.
Yes. The results include all 25 cohort products, provider-level splits, cited-domain frequency, and answer-level evidence. Seven cohort brands appeared at least once across the 80 eligible discovery answers.
The study tested OpenAI, Anthropic, Google, and xAI through their APIs with required web-search grounding. The exact model identifiers, collection timestamps, and result-file hashes are included in the downloadable manifest.
No. API responses can differ from consumer chat products because prompts, routing, personalization, models, and search behavior can differ. The Index is a time-stamped directional comparison of one controlled test.
