Web design and development is an umbrella term that describes the process of creating a website. Like the name suggests, it involves two major skill sets: web design and web development. Web design determines the look and feel of a website, while web development determines how it functions.
Websites are the center of all marketing efforts. A website can be the first place where potential customers interact with you and learn about your business. It can also be where they land on last, to make a purchase, because they were redirected from an email, a Facebook ad or an Instagram post.
In digital marketing, a landing page is a standalone web page, created specifically for a marketing or advertising campaign. It's where a visitor “lands” after they click on a link in an email, or ads from Google, Bing, YouTube, Facebook, Instagram, Twitter, or similar places on the web.
A Dynamic Website (also referred to as a database-driven site) requires web programming and database design. A dynamic website contains information and content that changes, depending on factors such as the viewer of the site, the time of the day, the time zone, or the native language of the country the viewer).
