# HummingDeck > Sales deck sharing and engagement tracking platform. Share decks via trackable links, see who opens them, how long they spend on each page, and follow up at exactly the right moment. HummingDeck helps sales professionals (SDRs, Account Executives, Sales Managers) replace dead email metrics with real-time engagement signals. Upload a presentation, generate a personal share link, and get instant visibility into prospect behavior: who opened it, time per page, completion rate, downloads, return visits, and link clicks. A three-layer bot-detection system combines user-agent matching, hosting-network signals, and delayed client-side interaction signals to reduce common email-security scanner noise. Bot filtering is imperfect and does not prove that every remaining event came from a person. ## Core Features - [Engagement Tracking](https://hummingdeck.com): Real-time view notifications, time per page, completion rates, download monitoring, return visits - [Bot Detection and Measurement Limits](https://hummingdeck.com/for-ai#measurement): Layered scanner-noise filtering applied before flagged activity affects normal view metrics, with definitions and interpretation limits - [Share Link Management](https://hummingdeck.com): Personal and anonymous links with per-link controls (download permission, email capture, expiration) - [Analytics Dashboard](https://hummingdeck.com): Team-wide engagement metrics, geographic insights, per-page analytics, trend visualization - [Approval Workflows](https://hummingdeck.com/rooms): Built-in accept / request changes / decline workflow with decision notes and timestamped audit trail — no separate e-signature tool needed (Pro and Business plans) - [Digital Sales Rooms](https://hummingdeck.com/rooms): Branded deal rooms with documents, videos, embeds, mutual action plans, and approval workflows in one shared link - [Bulk Import](https://hummingdeck.com): Generate up to 1,000 trackable links at once from CSV or Close CRM Smart Views ## Supported Formats PDF, PowerPoint, Word, Google Slides, Google Docs (via URL), interactive HTML files, and static website ZIP bundles.
