9. [6] (d) Arguments for internet advertising: Cost - compared to TV and newspapers, internet advertising is inexpensive; Wide coverage – easy to reach global market; Measurement – easy to track how effective the internet advertising is using online surveys, etc. so Keeya knows how to increase effectiveness; Target consumers – to particular groups of consumers based on customer profiling
10. [6] (d) Arguments against internet advertising: Advertising overload – too many banners and popups appear so consumers ignore them; Scope - there are consumers who prefer not to view or buy over the internet; Blocking - some consumers block adverts on their browser so the advert will not be seen; Distractions – consumers can get distracted by other items they see on the internet such as the news and forget about the advert
11. [6] (d) Evaluation: Internet advertising can be very effective for Keeya, especially if her own website can be easily found by a search engine and she also uses social media adverts. Keeya will need to measure the responses to her internet advertising and if it is not effective, create a better/different style of advertisement.
