Marketing, Promotion & Web Agencies records businesses whose trade is the promotion of other businesses and brands — through digital advertising, web design, content production, social media management, and search optimisation. The Cornerstone almanac logs each listed agency by its active web address and stated service, without endorsing any particular methodology or outcomes claim. Twenty-eight entries are currently on file, with operations spanning Asia, Europe, and the Americas. Agencies and web studios with a verifiable online presence and client-facing service may submit for inclusion using the standard add form.
