Web design encompasses many different skills and disciplines in the production and maintenance of websites. The different areas of web design include web graphic design; interface design; authoring, including standardised code and proprietary software; user experience design; and search engine optimization. Often many individuals will work in teams covering different aspects of the design process, although some designers will cover them all. The term web design is normally used to describe the design process relating to the front-end (client side) design of a website including writing mark up. Web design partially overlaps web engineering in the broader scope of web development. Web designers are expected to have an awareness of usability and if their role involves creating mark up then they are also expected to be up to date with web accessibility guidelines. Web designers use a variety of different tools depending on what part of the production process they are involved in. These tools are updated over time by newer standards and software but the principles behind them remain the same. Web graphic designers use vector and raster graphics packages to create web-formatted imagery or design prototypes.

Web development is a broad term for the work involved in developing a web site for the internet (world wide web) or an intranet (a private network). Web development can range from developing the simplest static single page of plain text to the most complex web-based internet applications, electronic businesses, and social network services. A more comprehensive list of tasks to which web development commonly refers, may include web design, web content development, client liaison, client-sideserver-side scripting, web server and network security configuration, and e-commerce development. Among web professionals, "web development" usually refers to the main non-design aspects of building web sites: writing markup and coding. Most recently web development has come to mean the creation of content management systems or cms. These cms can be made from scratch, proprietary (such as open text) or open source (such as wordpress). In broad terms the cms acts as middleware between the database and the user through the browser. A principle benefit of a cms is that it allows non-technical people to make changes to their web site without having technical knowledge. Since the commercialization of the web, web development has been a growing industry. The growth of this industry is being pushed especially by businesses wishing to sell products and services to online customers.

Registration of a domain name establishes a set of name server records in the dns servers of the parent domain, indicating the ip addresses of dns servers that are authoritative for the domain. This provides a reference for direct queries of domain data. Registration of a domain does not automatically imply the provision of dns services for the registered domain. Most registrars do offer dns hosting as an optional free service for domains registered through them. If dns services are not offered, or the end-user opts out, the end-user is responsible for procuring or self-hosting dns services. Registrars require the specification of usually at least two name servers. A domain name is an identification string that defines a realm of administrative autonomy, authority or control within the internet. Domain names are formed by the rules and procedures of the domain name system (dns). Any name registered in the dns is a domain name. Domain names are used in various networking contexts and application-specific naming and addressing purposes. In general, a domain name represents an internet protocol (ip) resource, such as a personal computer used to access the internet, a server computer hosting a web site, or the web site itself or any other service communicated via the internet. In 2014, the number of active domains reached 271 million.

A web hosting service is a type of internet hosting service that allows individuals and organizations to make their website accessible via the world wide web. Web hosts are companies that provide space on a server owned or leased for use by clients, as well as providing internet connectivity, typically in a data center. Single page hosting is generally sufficient for personal web pages. A complex site calls for a more comprehensive package that provides database support and application development platforms (e.g. Php, java, ruby on rails, coldfusion, or asp.net). These facilities allow customers to write or install scripts for applications like forums and content management. Also, secure sockets layer (ssl) is typically used for e-commerce. The host may also provide an interface or control panel for managing the web server and installing scripts, as well as other modules and service applications like e-mail. Some hosts specialize in certain software or services (e.g. E-commerce), which are commonly used by larger companies that outsource network infrastructure. The scope of web hosting services varies greatly. The most basic is web page and small-scale file hosting, where files can be uploaded via file transfer protocol (ftp) or a web interface. The files are usually delivered to the web "as is" or with minimal processing. Many internet service providers (isps) offer this service free to subscribers. Individuals and organizations may also obtain web page hosting from alternative service providers. Personal web site hosting is typically free, advertisement-sponsored, or inexpensive. Business web site hosting often has a higher expense depending upon the size and type of the site.

Online advertising, also called online marketing or internet advertising, is a form of marketing and advertising which uses the internet to deliver promotional marketing messages to consumers. It includes email marketing, search engine marketing (sem), social media marketing, many types of display advertising (including web banner advertising), and mobile advertising. Like other advertising media, online advertising frequently involves both a publisher, who integrates advertisements into its online content, and an advertiser, who provides the advertisements to be displayed on the publisher's content. Other potential participants include advertising agencies who help generate and place the ad copy, an ad server which technologically delivers the ad and tracks statistics, and advertising affiliates who do independent promotional work for the advertiser. Online marketing platform (omp) is an integrated web-based platform that combines the benefits of a business directory, local search engine, search engine optimisation (seo) tool, customer relationship management (crm) package and content management system (cms). Ebay and amazon are used as online marketing and logistics management platforms. On facebook, twitter, youtube, pinterest, linkedin, and other social media, retail online marketing is also used.
