URL is the address of a website on the Internet. It indicates the location of a resource as well as the protocol used to access it. Also known as a Universal Resource Locator (URL) and Web Address.
Tim Berners-Lee and his Internet Engineering Task Force working group developed the first URL in 1994.
A standard URL includes the following elements:
Protocol used to access the resource, Location of the related server, Location of the resource in a directory structure.
All URLs are presented as in the order of below:
Protocol name "HTTP or HTTPS", Colon and two slashes "://" Location of the server or domain name "popupsmart.com" Location of the resource on the server "/encyclopedia/" Fragment identifier "#how-a-visitor-come-this-page"
So, the formatted URL will look like this:
The "www" is not actually part of the technical protocol. Websites just started using this to indicate the user is using the World Wide Web.
S on the HTTPS protocol stands for "Secure," which means your browser and the website you connect encrypt your communication. No 3rd party would track your data without permission, thanks to Secure characteristic. Therefore, Google strictly recommends using HTTPS protocol while developing a website URL.
