A backlink is a hyperlink from one website to another. Backlinks are important for SEO because they can help to improve a website's search engine ranking. When a website has more high-quality backlinks pointing to it, search engines view it as more authoritative and relevant to a particular topic.

A Short URL (Uniform Resource Locator) is a condensed version of a regular URL that directs a user to a specific webpage. Short URLs are used to save space and make it easier to share links, particularly on social media platforms where character limits are in place.
