A Google marketing programme that compensates website publishers for allowing Google to automatically display relevant advertising on their sites. Relevance is determined by keywords. Text, graphics, and video can all be used in the adverts. They’re made to look good while remaining inconspicuous to the website’s content on both desktop and mobile devices. Publishers have some control over ad rejection and prioritisation by rejecting advertising they don’t like. Publishers are frequently compensated on a pay-per-click (PPC) basis.
