Advertising is a very common form of showing the various products and services offered by a company or industry. Among different types of advertising web advertising or online advertising has become very popular. Online advertising is basically a form of advertising that uses the Internet (World Wide Web) to showcase marketing messages and attract customers into buying products. Online ads can be found in many places such as on search engine display pages, Rich Media ads, online banner ads, online classified ads, social network ads, and even on e-mail advertisement including those irritating spam mails.
One of the most important aspects of online advertisement is that it is not limited by time or location. Due to the high flexibility of the online ads they can reach across many countries and all over the world. Also these advertisements can be really interactive. Examples of these interactive ads are online video ads of various products. These ads are complementary to the television ads and can thus provide a large directory for the customers to view ads for a wide range of products. Also these ads are popular with the online customers since they allow you to see ads only when desired, quite unlike the interruptive ads found on television.
