New to AI visibility tools? This page defines every term Citd uses, in one or two sentences. Each entry links to the page where you can go deeper. Skim it once, then come back whenever a word isn't clicking. You don't need to memorize these. Most pages define terms as they use them — this is just your quick reference. ### Action A specific, prioritized fix Citd recommends to improve your visibility — for example, "rewrite this product title" or "add structured data to these pages." Actions live in an execution queue you can work through. See [Actions](/features/actions). ### AI Feed Citd's article generator. It writes fact-grounded, SEO-friendly articles designed to close your visibility gaps, then publishes them to your store or website. Also called the GEO blog. See [AI Feed](/features/ai-feed). ### Authority A score for how trusted your brand looks to AI assistants, based on how often independent, credible websites cite or mention you. Low authority usually means competitors get covered by editorial and review sites and you don't. See [Analysis](/features/analysis). ### Carousel mode A type of AI shopping answer that returns a visual row of product cards (name, image, price). It's the AI equivalent of a search results page, and your *position* in it matters a lot. See [Shopping Modes](/concepts/shopping-modes). ### Citation A specific link or source an AI assistant relies on when it answers a shopping question. Citd tracks which domains and pages get cited so you can see where influence comes from. See [Sources](/features/sources). ### Competitive gap The reason a competitor outranks you on a given prompt, broken into three parts: Authority, Relevance, and Readiness. It answers "why are they winning and I'm not?" See [Analysis](/features/analysis). ### Competitor A rival brand or store that Citd benchmarks you against. Citd detects competitors automatically from AI answers, and you choose which ones to actively track. See [Competitors](/features/competitors). ### Enrichment The workflow for applying AI-suggested improvements to your Shopify product data — better titles, descriptions, alt text, tags, and structured fields — that you review and approve before they go live. See [Enrichment](/features/enrichment). ### GEO (Generative Engine Optimization) Optimizing your brand to be recommended by AI assistants like ChatGPT and Gemini, the way SEO optimizes for Google. It's the core idea behind Citd. See [Why AI search matters](/get-started/ai-search). ### Intent What a shopper is trying to do with a query — buy now, compare options, research, check a specific brand, or find a feature. Every prompt has an intent, and high-intent prompts (Purchase, Comparison) matter most. See [Prompts](/concepts/prompts). ### Position (Rank) Where your brand appears in an AI answer when it's mentioned — position 1 is the first recommendation, position 3 is the third. Lower numbers are better. See [Metrics](/concepts/visibility). ### Project One workspace in Citd, tracking a single brand or store. Your project holds your topics, prompts, competitors, results, and settings. See [Project Settings](/features/project-settings). ### Prompt A real buyer question Citd runs on your behalf, such as *"best trail running shoes under \$150."* Your metrics are measured across the prompts you've made active. See [Prompts](/concepts/prompts). ### Readiness A score for how complete and well-structured your product data is for AI to understand — titles, descriptions, attributes, images, and structured data. Higher readiness makes you easier to recommend. See [Analysis](/features/analysis) and [Products](/features/products). ### Relevance A score for how well your products match what a prompt is actually asking for — the specific use case, feature, or buyer intent. Low relevance means you show up for broad queries but miss specific ones. See [Analysis](/features/analysis). ### Research mode A type of AI shopping answer that returns a long-form buyer's guide comparing options, rather than a grid of products. Being *cited* matters more than exact order here. See [Shopping Modes](/concepts/shopping-modes). ### Sentiment Whether your brand's mentions are framed positively, neutrally, or negatively in AI answers. It's the difference between "the top choice" and "a budget compromise." See [Metrics](/concepts/visibility). ### Share of Voice (SoV) Your slice of all brand mentions across your tracked prompts, compared to every competitor. It captures who *dominates* the conversation, not just who shows up. See [Metrics](/concepts/visibility). ### Shopping mode The style of answer an AI assistant gives — either Carousel (product grid) or Research (long-form guide) — depending on the buyer's intent. Knowing the mode tells you what kind of optimization will help. See [Shopping Modes](/concepts/shopping-modes). ### Source A website cited in an AI answer. Citd groups sources by type (your site, competitors, retailers, editorial, reviews, and so on) so you can see where authority comes from. See [Sources](/features/sources). ### Topic A product category your brand competes in, such as "trail running shoes." Topics organize your prompts and let you see where you're strong or weak by category. See [Topics](/concepts/topics). ### Tracking run One round of Citd running your active prompts against AI assistants and recording the answers. Runs happen weekly on Free and daily on paid plans, building your trends over time. See the [Quickstart](/quickstart). ### Visibility The percentage of your tracked prompts where your brand appears at all. It's your reach — how broadly you show up across the questions buyers ask. See [Metrics](/concepts/visibility).
