Presented by newspaper industry journal Editor & Publisher, the international contest recognises the best media-affiliated websites across 31 different categories.
Entries were judged by a panel of media industry experts based on criteria such as content, design, interactivity and innovation.
Mr Johnson Goh, Head and Vice President of ST701, said that his team was honoured by the recognition. "It is our intention for STProperty to remain as Singapore's top and trusted portal," he added.
The website's sister portals, STJobs and STClassifieds, were also finalists under the same category.
