A link (or hyperlink) is the location, or URL, where your piece of content ‘lives’ on the World Wide Web. Most times you can find the link at the top of your browser in its address bar. It starts with an ‘http://’ and can be a long stream of numbers, letters and characters. That entire sequence is your link and should be copied (ctrl + C for PC. Apple + C for Mac) from the address bar and pasted (ctrl + V for PC. Apple + V for Mac) where it says ‘Link’ on this page.
Note: Sometimes, if a site is updated often, it will also provide you with a ‘permalink’ so you can go directly to that specific piece of content. In this case, that will be the link you want to copy and paste.
