Free Online Advertisement
Online advertising is a form of promotion that uses the Internet 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.
One major benefit of free 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. Free Online advertising allows for the customization of advertisements, including content and posted websites. For example, Ad Words, Yahoo! Search Marketing and Google Ad Sense enable ads to be shown on relevant web pages or alongside search results of related keywords.
The use of free online advertising has implications on the privacy and anonymity of users. If an advertising company has placed banners in two Web sites. Hosting the banner images on its servers and using third-party cookies, the advertising company is able to track the browsing of users across these two sites. Many advertising operators have an opt-out option to behavioral advertising, with a generic cookie in the browser stopping behavioral advertising.
Free 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.
