Backlinks are links from one page of one website to another. If someone links to your site, then you have a backlink from that person. If you link to another website, then they have a backlink from you. For example, these words link to YouTube, so they now have a backlink from us.
Some examples include white text on a white background or black text on a black background, links hidden in small punctuation marks (like this one). A backlink is when one website links to another with anchor text. An example of a backlink is any article you find that links to another source or website. You can find examples of website backlinks all over the Internet, especially on popular blog sites that link to relevant content.
Here's another example of backlinks on the Oculus Where to Buy page. The buttons link to Microsoft, Walmart, etc.
