How many of these links are unique?

With your first story, you’ll typically see between 150-300 new unique domains to your site. Then, each subsequent story will have somewhere between a 5-15% link uniqueness rate. Our distribution team is constantly adding new publishers to our newswire, and we can move this lever up and down by playing with content strategy and localization to appeal to new publishers and editors. 

Our SEO team ran a blinded case study across our clients to understand the impact of link uniqueness and organic growth, and what we found was that there was a slightly negative correlation between the number of unique links and organic growth our clients saw over a term. In contrast, we saw a nearly perfect correlation between number of links and organic growth. This indicates that for our clients, link uniqueness is not as important for organic growth as the volume and quality of those backlinks/stories.
