What are backlinks, and how do they work?

@dudley Backlinks are incoming links from other websites that point to your website or webpage. These links act as "votes" for your website, showing search engines that your website is popular and should be rated more highly in search results. When a website links to yours, it also provides your website with free traffic and visibility. The more backlinks you have, the more visible your website is, increasing the chances that your website will rank higher in search engine results.
