It is called implied linking as there is basically no link to go back to the source site. Brand mentions and online citation must be handled carefully and well-incorporated into the site content; this is done in several forms. In the content, the brand mentions are generally connected to the products or services, and how those are connected to the content is explained. It can be in the comments what is finally implicitly integrated well into the content also. So long as the brand or website name is used, a brand name or citation is created.
Also, they launched a brand new Site Audit tool. They are still polishing it but it already gets some enthusiastic reviews. Unlike other tools, it does not just show you website errors and SEO issues and relevant recommendations. It lets you create your own issues and configurations for the site audit. I think it’s really great in the constantly changing environment of today’s SEO.
