Bandwidth refers to the amount of data that can be transferred between your website’s server and a visitor’s browser within a given period of time. In simple terms, it affects how quickly your website content - such as pages, images, videos, and files - can be delivered to visitors.
A connection with higher bandwidth can transfer the same amount of data faster than a connection with lower bandwidth. This usually results in faster loading times and a smoother experience for visitors, especially during peak traffic times.
Bandwidth can also be described as your website’s “data capacity.” The more visitors you have, and the more content your pages include (high-resolution images, videos, downloadable files, etc.), the more bandwidth your website may require. If your website exceeds its available bandwidth, visitors may experience slower performance or limited access until the usage resets or the limit is increased.
