# False negative

Glossary · Analytics

Canonical page: https://datasdk.ai/glossary/false-negative

A false negative is a missed detection when the condition is actually present.

## Why it matters

Remember that no match does not prove absence of a potential customer.

## Illustrative example

A relevant business visits but cannot be matched.

## What to check

The full set of missed matches may not be measurable from your records alone.

## How Data SDK fits

Data SDK connects website visits with available company details worldwide, from startups to larger businesses. Coverage and fields vary. Start free trial opens an email request; terms are confirmed with the team. The full API is coming soon.

These are suggested workflows, not a list of built-in integrations. Use your own approved analytics, CRM, and research process where needed. Matches and fields vary. A company match does not identify a person or prove buying intent.
