Syndicated links carry SEO value, and since so few marketers use this strategy, earned syndication is Stacker Studio's superpower. Because SEOs have been skeptical over the years, Patrick Stox of Ahrefs asked Google's Gary Illyes about it in a Reddit AMA, and Gary's answer basically confirmed syndicated links have an impact on site authority.
Stacker Studio links combine an in-text, dofollow backlink with a rel=canonical tag in the HTML, both attributing you as the original creator of the content. This, paired with an average DR value of 55 among Stacker's newswire, results in a large number of fresh, high-quality link authority pointing to your domain.
This is the same strategy leveraged by NerdWallet, LendingTree, and Redfin to grow their organic profiles for years, and I'd be happy to send some more information on this for corroboration.
