This glossary is the single source of truth for Meridian definitions. If you see a term in the dashboard or docs, it should match the definition here.
Most metrics in Meridian are scoped to your tracked prompts and the filters you apply (date range, platform, region, topics, attributes, and company profile).

Core objects

Company Profile

A Company Profile represents a brand or client inside your organization. Each profile can have its own integrations (Google Analytics, Vercel), its own search terms, and its own datasets. You manage profiles in Settings → Company Profiles.

Organization

An Organization is the workspace container that holds company profiles, members, billing, and settings.

Prompt

A prompt is a tracked question you want to win in AI assistants. Prompts should represent real user discovery and evaluation behavior (for example: “best __ for __” or “__ vs __”). Prompts live in Analytics → Prompts.

Topic

A topic is a grouping mechanism for prompts (usually a product line, category, or theme). Topics help you organize and scale tracking.

Attribute

An attribute is a tag/segment you can apply to prompts to filter and group analysis (for example: “Beginner,” “Enterprise,” or “High intent”). Attributes are used primarily in Analytics → Prompts.

Run

A run is one execution of a prompt on a specific platform and region in a specific time window. Runs are the unit Meridian uses for evidence. Runs include:
  • whether you were mentioned,
  • your position (if mentioned),
  • citations (if present),
  • and a response snippet/full response.

Mention

A mention means your brand (or product) appears in the AI response for a run.

Position

Position is your rank in a specific run when the answer is list-like (for example: #1, #2, #3).

Prominence

Prominence is your average position when you are mentioned. Lower is better. Formula: Prominence = average(position | mentioned) Prominence is shown on Home and also per prompt in Analytics → Prompts.

Citation

A citation is a source reference in an AI answer (a domain or URL). Citations are analyzed in Analytics → Citations.

Domain

A domain is the site-level source (example.com). Domains are typically used for strategy (“which sites matter most?”).

URL

A URL is the page-level source (example.com/page). URLs are typically used for execution (“which exact pages are being cited?”).

Citation types: Owned / Off-page / Social / Competitor

Meridian classifies citations into:
  • Owned: your domain(s)
  • Off-page: third-party editorial sites
  • Social: community/social platforms (Reddit, LinkedIn, forums)
  • Competitor: competitor domains

Metrics (what they mean + how they’re calculated)

Visibility (%)

Visibility measures how often your brand is mentioned across runs in the selected timeframe. Formula: Visibility = (runs where you are mentioned / total runs) × 100 Example: 200 runs, mentioned in 96 → Visibility = 96/200 = 48% Where it appears: Home, Analytics → Prompts How to interpret:
  • Low visibility means you are frequently excluded from answers for your tracked prompts.
  • Visibility usually improves when you increase coverage and/or become present in the sources AI trusts.

Share of voice (%)

Share of voice (SOV) estimates how much of the recommendation space you occupy relative to competitors. Formula: SOV = (mentions of you / mentions of all tracked brands) × 100 Example: You are mentioned 90 times; all tracked brands total 500 mentions → SOV = 18% Where it appears: Analytics → Prompts
Answer formats vary (some answers list 3 brands, others list 10). Use share of voice directionally and use a specific run’s details as the source of truth for exact ranked lists.

Citation Rate (%)

Citation Rate measures how often your owned domain is cited in answers. Specifically, it is the share of runs where the response contains at least one citation to your owned domain(s). Formula: Citation Rate = (runs with ≥1 citation to your domain / total runs) × 100 Example: 200 runs, your domain cited in 35 → Citation Rate = 17.5% Where it appears: Home KPI; details in Analytics → Citations How to interpret:
  • Higher citation rate usually means AI is relying on your pages as evidence more often.
  • Drops often mean the ecosystem is relying on other sources (editorial, competitors, or social) instead of your pages.

Sentiment (%)

Sentiment summarizes how AI describes your brand across dimensions (fees, reliability, security, etc.). It is shown as an overall score plus a dimension breakdown. Where it appears: Home KPI; Analytics → Sentiment How to interpret:
  • If sentiment drops, drill into the dimension and read the underlying negative mentions.
  • Sentiment improves fastest when you address objections with evidence on citeable pages.

Products: Mentioned / Not mentioned

In Analytics → Products, each product is labeled based on whether it appears in AI answers for your tracked prompt set.
Product monitoring depends on your prompt set. If you don’t track prompts where products could be recommended (for example “best basketball shoes”), products will often show Not mentioned.

Platforms and regions

Platform

The AI platform where the run occurred (ChatGPT, Gemini, Perplexity, AI Overviews / AI Mode, Copilot, etc.). Platform matters because different platforms rely on different sources.

Region / Country

The geographic context for the run (if enabled). Region matters because answers and sources can differ by geography.

Website concepts

Website → Pages

Pages scores and lists your URLs, surfacing technical and content recommendations that improve crawlability and citeability (for example: adding FAQs, adding schema, fixing meta descriptions).

Website → Referrals

Referrals shows click-through sessions from AI platforms as measured in your connected Google Analytics property (and optional Revenue if GA ecommerce is enabled). This is directional and typically undercounts total AI influence.

Website → Crawlers

Crawlers shows AI crawler/bot visits when connected (currently via Vercel). It helps validate discovery and diagnose crawl blockers.

Action concepts

Opportunities

Opportunities is a prioritized list of content recommendations designed to improve visibility, citations, and rank for your tracked prompt set.

Content

Content is where you create/manage briefs and generate articles:
  • briefs can come from Opportunities or be created manually,
  • briefs can be generated into articles,
  • articles can be refined and then copied into your CMS.

Off-page

Off-page is split into:
  • Editorial: most-cited editorial targets for your prompts
  • Social: most-cited social/community targets for your prompts
  • Directories: most-cited directory targets for your prompts
All three lists refresh weekly. The goal is to add trusted language about your brand where AI already trusts sources.

Brand Kit

Brand Kit stores your brand identity, voice/style, writing samples, and a Knowledge Base. It helps generated work stay accurate and consistent. Use Knowledge Base for deeper materials like differentiators, claims boundaries, and competitive context.

Settings concepts

Search terms

Search terms are the words Meridian uses to detect brand mentions in AI responses. If search terms are too narrow, you can miss mentions; if too broad, you can over-count.

Seats / roles

Members have roles (Member, Admin). Roles control access to settings and management actions. Seats used shows your current seat utilization.
