In a nutshell, digital PR is all about increasing brand awareness and engagement through online channels such as websites, blogs, social media, and online news. This is done by creating relevant and newsworthy content that is then sent out to the media.
For digital PRs, the main goal is to achieve high-quality backlinks from these campaigns which helps signal to Google that your website is reputable, and ideally improves their rankings in the search engine results pages (SERPs).
