Wiele's AI Visibility Monitoring retainer reports four core metrics: citation share, prompt coverage, source weight distribution, and named competitor citation share (Standard and Pro tiers). These metrics are measured directly from engine output. They are not modelled, projected, or interpolated. Every number in every monthly report is replayable from the citation log Wiele maintains for the client.
The four engines
Every monthly run executes against ChatGPT, Gemini, Perplexity, and Claude — accessed via their public web applications, in fresh sessions, with no logged-in personalisation. The web app is what buyers see; the API can return different output. The web app run is what the retainer measures.
The prompt panel
Each client has a versioned prompt panel — 25 prompts (Lite), 60 prompts (Standard), or 100 prompts (Pro). Prompts span branded queries, commercial-investigation queries, comparison queries, service-specific queries, local queries where applicable, and methodology queries. The panel is signed off by the client at kickoff and re-reviewed at each Quarterly Business Review. Mid-quarter changes are forbidden because they break month-over-month comparability.
Citation share, defined
Citation share is the percentage of panel prompts in which the client brand appears in the engine response, measured per engine, per month. It is reported per engine and as a four-engine average. It is not reported as a single combined “AI ranking” — there is no such number. The four engines have four citation functions, and collapsing them loses signal that drives action.
Source weight, defined
Not every citation carries equal weight. Wiele scores citations into four tiers — tier-1 (named press, peer-reviewed venues, recognised analyst firms, regulatory and government sources), tier-2 (credible secondary publications, named-author blogs, established forums), tier-3 (general web, anonymous content, content farms), and owned (the client's first-party content or the founder's owned surfaces). The taxonomy is maintained by founder and reviewed quarterly. Updates are logged with date and reason.
Measured lift vs modelled attribution
Citation share, prompt coverage, source weight distribution, branded search volume (pulled from Google Search Console), and featured snippet captures are measured lift — directly observable in engine output or in Search Console. Influenced pipeline (in Standard and Pro reporting where the client provides CRM access) is modelled attribution — opportunities the client's CRM tags as having an AI-surface or organic-search touchpoint in the buying journey. The distinction is named explicitly in every report. The two answer different questions.
What Wiele does not promise
Wiele does not guarantee specific citation share outcomes. Engine algorithms drift. Competitors ship work. New entrants enter the panel. The retainer commits to producing the cycle — engine runs, citation logs, action queues, monthly reports, and quarterly reviews — at the documented standard. Outcomes are measured against the prior baseline, reported honestly, and acted on through the next month's queue.
Wiele does not predict future citation share. The retainer reports observed lift. Forecasting is a Sovereign concierge service.
Wiele does not aggregate the four engines into a single “score.” Single-number rankings destroy the per-engine signal that drives action.
Audit posture
Every client has access to read the citation log that underpins their reports — on request. If a number in any report cannot be replayed from the log, the report is wrong and Wiele rebuilds it. This standard is not a value-add; it is the floor.
Engine algorithm field notes
Wiele tracks observed shifts in citation behaviour across the four engines and publishes notable portfolio-wide shifts in client reports as engine algorithm field notes. Where Wiele believes a shift is engine-wide rather than client-specific, this distinction is named explicitly. Field notes inform panel construction at the next quarterly review.
Tier scope
The Lite, Standard, and Pro tiers differ in panel size, run cadence (Lite/Standard monthly; Pro bi-weekly), competitor tracking depth (Standard 3, Pro 5), featured snippet tracking (Pro only), modelled influenced pipeline (Standard light, Pro full), and action queue depth (3, 5, or 10 actions per month). Methodology rigour is identical across tiers. A Lite client receives the same standard of work; they receive less of it.
