This section of the Quorum45 chronicle documents web-based operators in digital marketing, online advertising, web analytics, and marketing consultancy. The 27 entries currently on file represent agencies and specialist consultancies from multiple countries. Quorum45 files these operators as directory entries and does not endorse or evaluate their services. Operators in the digital marketing space will find this section the appropriate place to submit a listing. The directory treats marketing operators the same as any other — a legitimate web presence and a submitted URL are sufficient for inclusion.
