  • What is web development?

    Web development is the technical process of building a website for the internet or a private intranet. It involves nonvisual design tasks such as coding and programming. Front-end web development builds the code that determines what a user sees in a browser window. Back-end web development creates the server code that manages a website's functions.

  • What does a web developer do?

    There are three types of web developers.

    • Front-end developers write client-side script based on the visual design conceived by a web designer. The code executes in a browser window and brings the visuals to life, creating the look and feel of the website elements a user interacts with.
    • Back-end developers write server-side script, which is the code that makes the website function, such as forms, links, and e-commerce transactions.
    • Full-stack developers handle both front-end and back-end tasks.

    Depending on the complexity of a project, there may be a team of developers involved.

  • What is e-commerce website development?

    E-commerce website development is the process of building an online store that enables companies to sell goods and services and accept payment over the internet. An e-commerce website requires:

    • Inventory of products organized by category
    • Well-written product descriptions
    • High-quality product images
    • Shipping information
    • Secure checkout

    A web developer can recommend a suitable e-commerce platform and bring these elements together in a functional site.

  • Which is better, a web designer or a web developer?

    Web designers and web developers have different skills. Web developers create the functionality of a website, such as content management systems, databases, e-commerce stores, and security features. They also ensure a website works on multiple devices including smartphones, desktops, and tablets. Web designers can create the overall look and visual concept of a website, including graphical elements, but a web developer is usually needed to implement the design. Most website projects require a team approach.

  • What do web developers use to build websites?

    Web developers use a variety of tools and programming languages depending on the requirements of a project. Back-end developers may be proficient in:

    • Python
    • Java
    • PHP
    • SQL
    • C#
    • MySQL
    • MongoDB
    • Ruby
    • Ruby on Rails

    Front-end developers are often familiar with languages such as:

    • HTML
    • XML
    • CSS
    • JavaScript
    • jQuery
    • React
    • AngularJS
    • REST
    • SOAP
  • Is a web developer a software engineer?

    While web developers and software engineers both work with programming languages, their job responsibilities differ. A web developer builds websites and web apps that help businesses, government, nonprofit organizations, and entrepreneurs deliver information or services to their customers and clients. Software engineers create computer programs and software applications that operate on various devices such as laptops, smartphones, and tablets.

  • How do I develop a website?

    There are several options for developing a website. Do-it-yourself publishing tools such as Wix and Squarespace are relatively easy to use but limited in functionality. A content management system such as WordPress offers plug-in features but requires coding knowledge and time investment.

    An experienced professional web developer can build a website requiring an e-commerce platform, log-in, database features, and other complex integrations. They can also assist with technical questions related to hosting, search engine optimization, and ongoing maintenance and support. There's a financial cost to hiring a professional, but there's a benefit to their expertise, and it saves time that can be used on other marketing efforts.
