The reason why brand blogging or vlogging is so influential is because it gives a sense of transparency in communication for the consumers. They share information of value that people engage upon (Chaffey & Ellis-Chadwick, 2012 p537). For instance, make-up vloggers will give positive or negative reviews on the products they’ve been using and this has significant impact on whether products are bought, this is most effective as you can see the end results with the products used – this becomes eWOM where anyone on the internet has access to what’s been said (Hung & Li, 2007).
How the consumer perceives the vlogger is critical in influencing online buyer behaviour, as trust and usefulness of product have become factors which consumers look for, with many vloggers gaining this trust from people watching (Hsiao et al, 2010).
