Computers produce a new world. It is used in people's daily lives, as well as the internet. Some are just used for entertainment but mostly it plays an important role in our lives. Some computers are even more powerful than the human brain, which is a paradox since it was conceived with the ingenuity of humans.

From its introduction in the early 90s, the internet has risen to become the most powerful tool for large companies, small businesses and even individuals. Many things have changed when computers were invented, and many more were altered with the coming of the internet. Perhaps the most glaring characteristic of the modern world is the virtual exchange of information over the World Wide Web. E-business, eCommerce and e-Marketing are terms coined to mean the changing conduct of companies today. With the cheaper cost offered by the internet, more and more entrepreneurs are offering their products and services over the web. Truly, the internet has proven to be an invaluable tool to companies with advertising over the web known to be more effective and less expensive.

The main advantage of internet marketing has something to do with the sphere of influence that any marketing strategy can have. Compare the costs of an advertisement placed in a telephone directory ($20,000 a year) to internet advertising ($0.7 per person), and you will realize that you will only need around $26,000 to put up a site and advertise it to around 300,000 people. This is a huge change from the conventional methods of advertising and business analysts also say that as more people are reached by strategies employed by internet marketers, internet advertising can more effectively drive sales, and generate higher revenue for businesses. It also gives immediate feedback and in a matter of seconds, advertisers are able to measure the effectiveness of their campaigns based on the number of user views, responses and clicks on a particular ad.

The advantages of the internet extend not only to big corporations but also to small businesses and individuals. As the number of business opportunities becomes available online, there is also greater opportunity to grow for small businesses and increase wages for working individuals. Home-based businesses are widespread with the promise of an easy way to earn money. If you own an internet site like Newstale.com that provides local classifieds and forums for jobs, services and local community for events, knowing the pros and cons of internet marketing can surely help your business.

If you are wondering how internet advertising works, there are quite a few strategies used. Some post clickable banners at the top or the bottom of a popular page. Others use pop ups while some send emails and newsletters to their members. Some sites create contests and gives out coupons that are tailored for online users. Others still create communities where their subscribers can talk about things which are for sale, other are about housing and some are about personals. Many sites try to drive traffic to their site through social book marking and registering to search engines.

If there are advantages to internet advertising, there are also disadvantages. For the most part, most internet users already have a purpose for surfing the web, so there will be a lot of times that ads are ignored. Not only that, most ads are made for the general public and do not target certain demographic characteristics so even if they do notice the ad, a lot will not choose to click. Aside from these, an advertiser needs to know a lot about the technical side of web development, which in itself is very tedious and requires a huge amount of time and effort.
