How could an entrepreneur use the Internet to advertise his/her business?

What will be an ideal response?

Answer: Advertisements on the Internet take five basic forms: banner ads, display ads, contextual ads, pay-per-click ads, and e-mail ads.
? Banner ads are small rectangular ads that reside on Web sites, much like roadside billboards, touting a company's product or service.
? Another form of Web advertising that is more difficult to ignore is display ads, which include pop-up ads, interstitial ads, and contextual ads. A pop-up ad appears on a separate window that pops up spontaneously, blocking the site behind it. It is designed to grab consumers' attention for the few nanoseconds it takes them to close the window.
? Contextual ads appear on users' screens when they download information such as news, sports, or entertainment from another site, and the ad is correlated to the user's interest or online behavior.
? Pay-per-click ads require companies to bid on top search engine listings using key words that they expect Internet users to type into a search engine when they are interested in purchasing a particular product or service. The higher a company's bid is for a key word, the more prominent is the location of its ad on the results that the search engine returns. E-mail advertising, in which companies broadcast their advertising messages by e-mail, is growing rapidly because it is so effective and so inexpensive.
? E-mail advertising takes two forms: permission e-mail and spam. As its name suggests, permission e-mail involves sending e-mail ads to customers with their permission; spam is unsolicited commercial e-mail.
