“…Such an approach has the advantage that it can identify ineffective advertising material prior to its use in market and also can be used to improve an advertisement through identification of its weak elements using experimental design methods. Such diagnostic advertising research has been used to study destination brochures to diagnose the effect of particular copy elements such as an endorser (Chang, Wall, & Lai, 2005;Van der Veen & Song, 2014), the effect of including images (Laskey, Seaton, & Nicholls, 1994), and to examine co-operative (multi-destination) or independent (mono-destination) format promotional material (McKinney, Hazeldine, & Chawla, 2009). Another use of such diagnostic studies has been to examine travel agency brochure advertising, including the effect of images of tour leaders (Wang, Hsieh, & Chen, 2002).…”
