Limy AI Glossary
The Limy AI Glossary provides clear, concise definitions of key terms used across the agentic web ecosystem. As AI search engines, LLM-driven interactions, and autonomous agents reshape how users disc

Core concepts
Prompt The user’s query to an AI surface (e.g., “best running shoes for knee pain”).
Response The AI’s response to a prompt, which may contain links to your site.
Prompt Hash A stable ID (hash) representing a canonicalized prompt text used for grouping/analytics.
Answer ID A unique identifier for a specific AI answer snapshot.
Rank/Position The placement of your link within the AI answer (e.g., first link shown).
Acquisition & tracking
AI Impression Recorded when a tracked prompt/answer containing (or likely leading to) your link is shown.
AI Click A click from the AI answer to your site (ideally via a decorated/redirected link).
Redirector / Link Decorator A shortlink service that wraps destination URLs to attach IDs/UTMs for deterministic attribution.
Destination URL (Dest URL) The specific page on your site that receives the AI-driven visit.
UTM Parameters Standard marketing tags (e.g.,
utm_source=chatgpt) persisted on arrival for analytics.AI Params Non-UTM tags used by Limy (e.g.,
answer_id,prompt_hash,link_id,ai_model).Referrer The page or service that led the user to your site (often the redirector domain).
Session A continuous period of user activity on your site.
Sessionization Logic that groups web events into sessions (server-side preferred).
Client ID (CID) First-party identifier stored in a cookie/local storage and joined to sessions.
Server Session ID A server-generated session key used to stitch events and reduce reliance on client cookies.
Event Collector (SDK/Edge) Limy’s server-side endpoint or edge function that receives web/app events.
Limy Pixel The lightweight snippet/SDK that initializes IDs and forwards events server-side.
On-site events & commerce
Page View A view of any page; typically the first event after AI Click.
Key Event Milestone interactions (e.g.,
view_item,add_to_cart,begin_checkout,lead_submit).Purchase Completed order with
order_id, value, currency, items.Order Value / Revenue Monetary value attributed to a purchase after discounts but before refunds.
Conversion (CVR) A desired outcome (often purchase or qualified lead) divided by a base (clicks or sessions).
Identity & stitching
Identity Graph A table joining
client_id,server_session_id, hashed email, and user/account IDs.Deterministic Match High-certainty connection (e.g., redirector
link_id+ session, or logged-in user).Semi-Deterministic Match Strong but not perfect signals (e.g., redirector referrer + near-instant session).
Probabilistic Match Statistical linkage using features like time gap, geo, device family, and URL similarity.
Cross-Device Stitching Merging identities across devices via hashed email, login, or server-side IDs.
Attribution & models
Attribution The method of assigning credit (and revenue) to touchpoints that influenced a conversion.
Attribution Model (Selector) Switchable logic: Last-Touch, First-Touch, Position-Based (40/40/20), Time-Decay, or Data-Driven.
Last-Touch 100% credit to the final touchpoint before conversion.
First-Touch 100% credit to the initial AI touchpoint (first impression/click).
Position-Based (40/40/20) 40% to first AI touch, 40% to last pre-purchase touch, 20% split across middle touches.
Time-Decay Credit weighted by recency (configurable half-life).
Data-Driven Attribution Algorithmic approach (e.g., Markov/Removal Effect or Shapley) estimating each touchpoint’s incremental impact.
Lookback Window Time span during which touches are eligible to receive credit (e.g., 7 days for clicks).
Attribution Confidence A 0–100 score reflecting certainty of the AI→session→order linkage.
Confidence Tiers High (≥0.80), Medium (0.60–0.79), Low (<0.60); used for reporting filters.
Attributed Revenue Revenue portion assigned to AI touchpoints under the active model and confidence threshold.
Analytics objects
Journey / Path The ordered set of AI and on-site events leading to a conversion.
Journey ID A unique ID for a specific path instance used in deep links and audit trails.
Timeline UI visualization of a journey’s events and timestamps.
Funnel Aggregated steps from Prompt Impressions → AI Clicks → Sessions → Key Events → Purchases.
Category A thematic grouping of prompts (e.g., “Running”, “Accessories”), used for reporting and drill-downs.
Prompt Leaderboard A ranked table of prompts by revenue, conversions, or efficiency.
Top URLs Report listing destination pages receiving the most AI-driven traffic/conversions.
Anomaly A statistically significant spike or drop (e.g., day-over-day or week-over-week) with a likely cause (traffic vs CR).
Lift Performance change versus baseline/previous period (e.g., +12%).
KPIs Key metrics surfaced at the top of dashboards (e.g., Attributed Revenue, Conversions, Avg Confidence).
Data model & fields
ai_impressionsTable of prompt/answer exposures withprompt_hash,answer_id, model, position, time, URLs.ai_clicksClick rows withlink_id,prompt_hash,answer_id, click time, dest URL.web_sessionsSession metadata (first/last seen, geo, device family, first AI params).web_eventsAll tracked events withevent_nameand properties JSON.ordersCommerce records with value, currency, items, and session link.attribution_resultsComputed credit per order by model, with confidence and explanations.link_idUnique ID assigned by the redirector when generating decorated links.ai_modelThe assistant model name (e.g., “gpt-4o”) stored with impressions/clicks.utm_source/utm_medium/utm_campaign/utm_contentStandard acquisition tags used alongside AI params.
Governance, privacy & reliability
Consent Gate Logic that defers non-essential tracking until user consent is granted.
Data Retention How long raw versus aggregated data are stored (e.g., 25 months for raw).
Access Controls Role-based permissions for sensitive views (identity, raw payloads).
Sampling Processing a subset of events for speed/cost, with safeguards for accuracy.
Backfill Recomputing histories after schema/model changes or late-arriving data.
Deduplication Process to prevent multiple event records for the same user action.
Schema Versioning Version tags on event payloads/tables to manage change safely.
UI & workflow terms
Model Picker Control to switch the active attribution model across widgets.
Confidence Threshold Filter to include/exclude low-certainty attributions from totals.
Drill-Down Navigation from aggregates (category) to specifics (prompts/URLs), then to journeys.
Export CSV/JSON/PNG outputs for tables and charts.
Virtualization Rendering technique that keeps tables fast with 1,200+ prompts.
Tooltip Copy Short definition text used in the UI (often derived from this glossary).
