Sharing and referral traffic that flows through private channels and cannot be traced by analytics.
Half our 'direct' traffic is really dark social: people pasting links into WhatsApp and DMs we can't see.
Rarity runs from 0 (a word everyone knows) to 100 (almost never seen outside specialist or literary writing). Level is the word's real difficulty on the CEFR scale, from A1 to C2.
