how effective are billboard ads
I think that this is what advertisers are shooting for when they pay the big price to get their ads up there. Regular billboards are just as effective as ever, even though there are now digital billboards being made that can have multiple ads on them and switch between them every few seconds.
Billboards are large advertising structures placed alongside busy roads to be noticed by drivers and passing pedestrians. It is sometimes called hoarding in other parts of the world. These billboards could attract pedestrians not only because they are large but also due to the variety of designs that it posses. It gives a designer so much room for customizing by using extensions and embellishments.
