Data Quality and Coverage
How accurate is the technology data?
Short answer
Technology detection is a strong signal for prospecting, not 100% perfect — websites change often. Review high-value accounts manually before outreach.
How to think about accuracy
Treat detections as signals, not guaranteed truth for every domain.
Why detection is hard
Sites change tools, hide scripts, use tag managers, or load different assets by region.
Get better results
