You've found your brand — now the question is what the screen is telling you. This guide walks the three views in the order you'll meet them, with links into the full reference for each. ## The chart: signals, numbers, movement Every [AI Ranking Chart](/docs/using/ai-ranking-chart) opens with three signal cards — the week's **Leader**, **Top Mover**, and **New Entry** — that give you the category's story before you scroll ([how each is determined](/docs/metrics/rank-and-weekly-movement)). Each row then carries the three numbers that matter: * **Rank** with its movement since last week — your position, and its direction. * **[DECA Score](/docs/metrics/deca-score)** — how strongly AI recommends the product, weighting position as well as frequency. * **[Mention Rate](/docs/metrics/mention-rate)** — how often it's recommended at all: your AI share of voice. One reading habit worth building early: the **Market Segment filters** don't slice the list — they re-rank it on questions from a different type of buyer. A product can be #2 overall and invisible for small-business buyers, and that gap is often the real finding. See [Segment Position](/docs/metrics/segment-position). ## The product details: evidence behind the position Open any row and the numbers turn into evidence, tab by tab. A useful reading order: 1. **[Chart History](/docs/using/chart-history)** first — is this week's position a spike or momentum? 2. **[Segment Position](/docs/using/segment-position-tab)** — which buyer contexts you win, and which you're absent from. 3. **[Off-Page Citations](/docs/using/off-page-citations)** — the reviews, forums, and media AI cites when it recommends the product, and the sources where you're missing. 4. **[On-Page GEO Patterns](/docs/using/on-page-geo-patterns)** — what the most-cited pages do on-page, with the HTML as evidence. 5. **[Prompt & AI Response](/docs/using/prompt-and-ai-response)** — the actual questions and answers behind all of the above. You don't need every tab on day one — the [product details overview](/docs/using/product-details) previews each one, so start where your question is. ## The Brand Hub: the company view Products chart individually, but every company also has a [Brand Hub](/docs/using/product-details#brand-hub) — all of its products and every category they appear in, one level up from any single chart. ## What's next Turn what you just read into a weekly working loop — diagnose, verify, act, track. The formulas and exclusion rules behind every number on the chart.
