Websites are typically dedicated to a particular topic or purpose, such as news, education, commerce, entertainment, or social networking.

Search engine optimization (SEO) is the process of improving the quality and quantity of website traffic to a website or a web page from search engines.

Web development is the work involved in developing a Web site for the Internet (World Wide Web) or an intranet (a private network).

Landing pages are often linked to social media, e-mail campaigns, search engine marketing campaigns, high quality articles or "affiliate account" in order to enhance the effectiveness of the advertisements.

A web application (or web app) is application software that runs on a web server, unlike computer-based software programs that are run locally on the operating system (OS) of the device.

Applications may be bundled with the computer and its system software or published separately and may be coded as proprietary, open-source, or projects. The term "app" often refers to applications for mobile devices such as phones.
