The advertising and promotion section of the register covers marketing agencies, search-optimisation firms, media buyers, and print-promotion houses. The twenty-seven entries span a range of disciplines — some specialise in digital channels while others handle print-based campaigns or general-brand work. The section does not extend to web-design studios unless the studio's primary business is promotional rather than technical. blinkbid.com represents the production-management and estimating side of the advertising trade. Visitors comparing agencies should note that listing in the directory does not constitute endorsement or independent verification of the firms' claims.
