The Wayback Machine is a digital library operated by the Internet Archive Organisation that allows older versions of websites to be archived and restored. This is important for neuroweb design because it allows web designers and marketers to analyse older versions of websites and understand how the design and content has changed over time. This allows them to better understand how users interact with the website and which design decisions are more successful. In addition, the Wayback Machine also enables the recovery of lost or deleted content, which can be beneficial for neuroweb design to ensure that important information on a website is not lost.
