Page speed refers to how quick your web-site loads for a user, something Google takes into
account while ranking websites since a faster loading page directly translate to better user
experience. If the interviewer asks what you would do to increase page speed, describe how
you've achieved this in the past with examples such as reducing image sizes, enabling
compression, reducing redirects, removing render-blocking JavaScript, leveraging browser
caching, improve server response time, using a content distribution network to compress files,
optimizing the code, etc.
