The analytics setup we do on every project
Structured event taxonomy (not the default 'page_view / click' mush): form_start, form_submit, phone_click, whatsapp_click, email_click, outbound_click, scroll_depth (25/50/75/100), article_view, article_completed, video_play, video_complete, purchase (with revenue). Every event has a documented definition, parameters, and business meaning. That's the difference between analytics that answer questions and analytics that generate PDF reports no one reads.
