Shanahan 1 bstract Onlin advrtising is a form of promotion that uss th Intrnt and World Wid Wb for th xprssd purpos of dlivring markting mssags to attract customrs. Exampls of onlin advrtising includ txt ads that appar on sarch ngin rsults pags, bannr ads, in-txt ads, or Rich Mdia ads that appar on rgular wb pags, portals or applications. Sinc it incption ovr 15 yars ago, onlin advrtising has grown rapidly and currntly accounts for 13% of th ovrall advrtising spnd (which is approximatly $700 billion worldwid)). larg part of th mor rcnt succss in this fild has com from th following ky factors: Prsonalization: offlin advrtising (via broadcast TV, radio, nwspapr tc.) is largly a broadcast form of communication whr as digital advrtising is much mor targtd and thus nabls a prsonalizd, and possibly informativ, mssag to consumrs. Intractivity: intrnt advrtising is bcoming incrasingly intractiv with th advnt of nw forms of advrtising such as social advrtising; this is nabls advrtiss and consumrs to oprat in a mor convrsant mannr. Engagmnt: consumrs ar spnding mor tim onlin than with any othr form of mdia thrby nabling a broadr rach and dpr connction with consumrs. Explainability: advrtisrs ar bginning to undrstand thir consumrs bttr. This shift in focus in digital advrtising from location (i.., publishr wb pags) to prsonalization has brought with it numrous challngs som of which hav rcivd a lot of rsarch attntion in th DIK communitis (Data, Information and Knowldg communitis) ovr th past 10-20 yars.
