Such services are convenient to use, as they reduce the time spent for data search. Such web portals attract large flow of visitors which makes them also beneficial for advertisers, placing their advertisements on the portals.
Portals can be divided into several categories:
1. Personal (Horizontal)
2. Vertical
3. Industrial
Personal portals enable users to customize website page according to their certain interests and preferences.
Horizontal portals are designed for a narrower range of consumers, thus they include more detailed information on a chosen subject. For example, USA.gov. or portal dmoz.org contain links for different theme web sites.
Portals that publish information related to a particular area of industry such as health care, automobiles, insurance, or food manufacturing, called industrial portals. For example, such web sites as The Car Portal, Health.org and others
Corporate portals are intended to provide access to corporate information for employers, employees, customers and business partners. Users of Corporate portals are able to share their personal information; employees from different departments can exchange data and collaborate with each other. Great example of such portal is web site of NCCC.
Due to the high rate of information exchange, the Internet has become an indispensable platform for the placement of rapidly changing data such as weather reports, traffic jams or breaking news. For example, Weather.com web site reflects not only the most recent data about weather, but also provides videos of natural disasters, downloadable applications for your computer or smart phone. Also inquisitive users can find tips about their hobbies or travelers info.
