FAQ
How is Google Analytics 4 detected?
From structural signatures in the public HTML and response headers (domains, paths, attributes, scripts). Every verdict lists how many times each pattern matched — nothing is guessed.
Can the result be wrong?
If only a bare brand keyword matches without structural evidence, we label it \u201clikely\u201d instead of \u201cconfirmed\u201d — we would rather under-report than cry wolf.
Optimization help is available
