In WordPress, a backlink is a hyperlink from another website that leads to your WordPress site.
When a website includes your web URL to any post, page, or any part of that website, your website gets a backlink from that website.
Backlinks, also called inbound links or incoming links, are important for search engine optimization (SEO) because they can help to increase your website’s visibility and credibility in search engine rankings.
The more high-quality backlinks your website has, the more likely it is to rank higher in search engine results pages (SERPs).
However, it’s important to note that not all backlinks are created equal – search engines tend to give more weight to backlinks from authoritative, relevant, and trustworthy sources.
