The invisible research path
Client-side analytics measure JavaScript running in a browser. An assistant fetching HTML does not run that script, so a material part of a product evaluation can disappear from the normal analytics view.
The gap is especially sharp on answer-producing pages: pricing, limits, retention, sub-processors, model lists, changelogs and status. A person can form an impression from marketing and postpone the evidence check. An agent asked a specific question goes directly to the primary source that can answer it.
A different measure of page value
Pages with low human engagement can have high value to an agent evaluating a vendor. That makes page value bimodal: one surface creates desire, while another supplies the evidence needed to recommend or reject a product.
Server-side collection does not replace human analytics. It adds the missing view: requests from identifiable agents, reported with their verification state and without treating those requests as visitors, sessions or people.
