No / Purpose: The aim of this research is to investigate how local company web sites can contribute towards the value and characteristics of city brands online, particularly where post-industrial cities are concerned, and to establish a predictive model for this. Design/methodology/approach: Interviews were conducted to gain an understanding of how post-industrial city brands can be influenced by local companies, leading to the notion of a 'constructed' city brand. An overarching brand model was developed based on the works of Christodoulides et al. and Merrilees and Fry and a survey of company web sites conducted. Structural equation modelling was then fitted to these data. Findings: Trustworthiness, responsiveness, online experience and emotional connection were confirmed as dimensions of company online brand value. It was further shown that company brand and constructed city brand are influenced by customer perceptions of brand value. Company brand was not, however, related to constructed city brand for the case study of Bradford, UK, which has a pervading negative reputation. Originality/value: A model incorporating company brand and city brand has been developed and validated for a typical post-industrial city that is in decline. The influence that local companies can exert on these brands via their web sites and behaviours was established. It is further demonstrated that company brands become disassociated from a city if it has a negative brand image.
