Digital Marketing & Web Registers documents twenty-seven accessions from the online marketing and web services industry: search consultancies, social media agencies, bid-management platforms, and creative web studios. The section reflects the international character of digital marketing, with entries originating across Asia, Europe, and the Americas. The Marginalia36 archivist catalogues these entries without evaluating the effectiveness of the services offered; commercial claims made within individual listings are the responsibility of the submitting organisation.
