# 2. Data Coverage & Data Types

Explore TickerTrends alternative-data coverage, metric types, and research-use limitations for investment research.

## Alternative data coverage

TickerTrends organizes source-level signals for investment research and KPI tracking. Use these signals to investigate demand, adoption, attention, and operating context.

Coverage includes:

* Search and discovery activity
* Web and digital activity
* Mobile apps and social discussion
* Commerce and product interest
* Developer and B2B adoption
* Financial and KPI context

Metrics may be observed, estimated, indexed, transformed, or modeled. They can be delayed, incomplete, or revised.

Detailed coverage, geography, history, cadence, and entitlements vary. Confirm available data in-product or during an evaluation.
