Data Quality and Coverage
Why does a website show the wrong technology?
Short answer
Wrong tags usually mean the site changed tools, left old scripts behind, or uses hidden/custom implementations — report examples so we can improve.
Common causes
-
Tool removed but script remnants remain
-
A/B tests or geo-specific loading
-
Agency staging vs production
-
Custom builds that mimic popular stacks
What you should do
For high-value domains, confirm manually before outreach.
