ONLINE ADVERTISING

Computer Engineering electronics Engineering Civil Engineering

Online advertising is a form of promotion that uses the Online and World Wide Web for the expressed purpose of delivering marketing messages to attract customers. Examples of online advertising include contextual ads on search engine results pages, banner ads, Rich Media Ads, Social network advertising, interstitial ads, online classified advertising, advertising networks and e-mail marketing, including e-mail spam. Competitive advantage over traditional advertising One major benefit of online advertising is the immediate publishing of information and content that is not limited by geography or time. To that end, the emerging area of interactive advertising presents fresh challenges for advertisers who have hitherto adopted an interruptive strategy. Another benefit is the efficiency of advertiser's investment. Online advertising allows for the customization of advertisements, including content and posted websites. For example, AdWords, Yahoo! Search Marketing and AdSense enable ads to be shown on relevant web pages or alongside search results of related keywords. Ethics Online advertising encompasses a range of types of advertising, some of which are deployed ethically and some are not. Some websites use large numbers of advertisements, including flashing banners that distract the user, and some have misleading images designed to look like error messages from the operating system, rather than advertisements. Websites that unethically use online advertising for revenue frequently do not monitor what advertisements on their website link to, allowing advertisements to lead to sites with malicious software or adult material. Website operators that ethically use online advertising typically use a small number of advertisements that are not intended to distract or irritate the user, and do not detract from the design and layout of their websites.[1] Many website owners deal directly with companies that want to place ads, meaning that the website linked to by the advertisement is legitimate. The overuse of technologies like Adobe Flash in online advertising has led to some users disabling it in their browsers, or using browser plug-ins like Adblock or NoScript. Many sites use centralized advertising services whose advertisement may be blocked as a side effect of security and privacy measures, because the services require JavaScript and cross-site requests to function, while such features are often not necessary to use the sites and are a potential source of vulnerabilities. Legitimate advertising often is opt-in, or has a clear opt-out option, which differentiates it from spam loading..
