Research Methodology

Primary Hypothesis

GEO adoption follows a bimodal distribution based on entity ownership.

Prompt Corpus

Maturity assessments across 400+ simulated organisational profiles.

Sampling Cadence

One-off baseline study for 2026.

Verification Level

Synthetic

Key takeaways

  • Adoption is bimodal: categories either run GEO as a funded programme or not at all. Very little sits in between.
  • The strongest predictor of adoption is not budget — it is whether a single owner exists for entity data.
  • Most 'we already do GEO' claims resolve to publishing FAQ blocks, which is stage one of five.

The five-stage maturity model

Adoption is easier to reason about as stages than as a percentage. Each stage is defined by what the organisation can do, not by what it says it believes.

  • Stage 1 — Ad hoc. Someone pastes the brand name into ChatGPT occasionally and screenshots the result.
  • Stage 2 — Measured. A prompt corpus exists and is sampled on a cadence. Nobody is accountable for the number.
  • Stage 3 — Owned. A named person owns Recommendation Share and reports it alongside pipeline metrics.
  • Stage 4 — Optimised. Entity, content and corroboration work is planned against measured gaps rather than intuition.
  • Stage 5 — Compounding. Answer-layer performance feeds product, PR and partnership decisions, not just marketing.

What separates stage 2 from stage 3

The jump from measuring to owning is where most programmes stall, and the blocker is almost never tooling. It is that no single function believes the metric belongs to them: SEO sees a content problem, PR sees a coverage problem, product sees a positioning problem.

The organisations that cross it do one unglamorous thing — they put Recommendation Share on the same weekly dashboard as pipeline, with one name against it.

Category patterns

Categories where the buyer researches conversationally and the purchase is considered — B2B software, healthcare, financial services, professional services — show the fastest adoption. Impulse and habit categories show the slowest, because the answer layer intercepts less of their demand.

Regulated categories are a special case: they adopt late but move fastest once they start, because they already maintain the canonical entity data that GEO depends on.

Observed failure modes

Three patterns account for most stalled programmes: publishing volume without structure, optimising for one engine and assuming the others follow, and treating a single week's sample as a trend when engine responses are inherently non-deterministic.

Evidence basis

How this entry was produced

Modelled analysis. Every figure on this page is produced by a model to demonstrate structure and method. It is not measured data and must not be cited as a finding.

Research type
Modelled analysis — figures generated by a model, not measured
Classification
Modelled analysis
Data collected
Published 2026-02-01. No client data collection took place for this entry.
Prompt sample size
Any corpus size quoted in the body describes the model's assumed corpus, not a corpus that was actually sampled.
Replays per prompt
Not applicable — no prompts were replayed against live engines to produce the figures on this page.
Engines covered
ChatGPT
Engine versions
Not stated. Engine vendors do not expose a stable build identifier for every model, so a version cannot be claimed accurately.
Methodology
Figures are generated from assumed distributions to demonstrate the structure of a CiteRank report. No engine responses were sampled to produce them.
Limitations
  • Do not cite any figure on this page as a finding, benchmark or market statistic. It is not one.
  • Numbers here demonstrate report structure only and have no predictive value for your brand.
  • AI engines are non-deterministic: an identical prompt can return a different answer on replay, so any figure derived from them is an estimate, never a fixed value.
  • Engine vendors change retrieval and ranking behaviour without notice, so anything stated here describes the stated window only.

Methodology, limitations and disclosure

Every CiteRank study states who produced it, what it measured and where it stops being reliable. The full scoring model is documented on the methodology page.

Limitations

  • Figures in this entry are modelled and clearly labelled illustrative. They demonstrate structure and method; they are not observed client results.
  • AI engines are non-deterministic: an identical prompt can return a different answer on replay, so every figure is a sampled estimate rather than a fixed value.
  • Engine vendors change retrieval and ranking behaviour without notice. Findings describe the sampling window stated above, not a permanent state.
  • Results describe the prompt corpus that was designed for this study. A different corpus for the same brand can produce a materially different picture.
  • This entry does not disclose a sample size, so its figures should not be treated as statistically representative.
