How accurate is the technology data?

Short answer

Technology data is a strong prospecting signal, but it is not perfect. Websites change frequently, so review high-value accounts before reaching out.

Why accuracy can vary

Websites add and remove tools, hide scripts behind tag managers, load tools only on certain pages, or keep old scripts after switching platforms.

This means that a technology may sometimes appear outdated or incomplete.
