Publicité en ligne[5] refers to the use of Internet[9] services to deliver promotional marketing messages to consumers. It encompasses a wide range of services, from email marketing[6], which started in 1978, to modern-day mobile advertising[4]. Online publicité[7] saw significant growth from the early 1990s with the advent of display ads and has since evolved to include various ad formats such as floating ads, expanding ads, trick banners, and News Feed Ads. The industry has also seen a shift towards integrating advertising into editorial content or services, focusing on médias sociaux[8] advertising, and increasing mobile ad spending. Data management platforms are used to aggregate and categorize user data, and programmatic advertising further targets ads using this data. Search Engine Marketing[2] (SEM) and Optimisation des moteurs de recherche[1] (SEO), sponsored searches, and mobile advertising are all critical facets of online advertising. This multi-faceted approach allows for a personalized and targeted advertising[3] experience for users.
Publicité en ligneégalement connu sous le nom de online marketing, Internet advertising, digital advertising ou web advertising, is a form of marketing and advertising that uses the Internet to promote products and services to audiences and platform users. Online advertising includes email marketing, search engine marketing (SEM), social media marketing, many types of display advertising (including web banner advertising), and mobile advertising. Advertisements are increasingly being delivered via automated software systems operating across multiple websites, media services and platforms, known as programmatic advertising.
Like other advertising media, online advertising frequently involves a publisher, who integrates advertisements into its online content, and an advertiser, who provides the advertisements to be displayed on the publisher's content. Other potential participants include advertising agencies that help generate and place the ad copy, an ad server which technologically delivers the ad and tracks statistics, and advertising affiliates who do independent promotional work for the advertiser.
In 2016, Internet advertising revenues in the United States surpassed those of cable television et broadcast television. In 2017, Internet advertising revenues in the United States totaled $83.0 billion, a 14% increase over the $72.50 billion in revenues in 2016. And research estimates for 2019's online advertising spend put it at $125.2 billion in the United States, some $54.8 billion higher than the spend on television ($70.4 billion).
Many common online advertising practices are controversial and, as a result, have become increasingly subject to regulation. Many internet users also find online advertising disruptive and have increasingly turned to ad blocking for a variety of reasons. Online ad revenues also may not adequately replace other publishers' revenue streams. Declining ad revenue has led some publishers to place their content behind paywalls.
