Why Website Development and Design is Important for your Business

Another key thing to note is that a website operates 24/7 while you, hopefully, do not. This allows your brand to reach timezones you may otherwise have forgone. 

Website development can be divided into two parts: front-end and back-end development.

Front-End Website Development 

Front-end website development involves the construction of what the users will see when they open the webpage. This includes content, design and interactions. For this, developers use – HTML, CSS, and JavaScript among other languages.

The UI/UX is extremely important. User experience details how the user interacts with your website. Ensuring the website functions smoothly and is easy to navigate is a delicate balance between art and science.

An effective website will often have a clean, well-organised navigation bar or menu that lists all of its web pages. This feature makes it simple for users to navigate and comprehend the information on your website. Choose simple & user-friendly navigation that will attract customers to visit.

A major opportunity for Irish businesses is eCommerce. Particularly for retail outlets that only have a physical store. Moving online allows for an entirely new revenue stream without having to invest in costly physical locations and take on additional staff.

Back-End Development

Back-end development is the behind-the-scenes aspect of the webpage and makes use of the database for front-end development. For this many different coding languages and frameworks are used to write the script such as PHP, Java, Python and Perl.
