Gain more control over how backlink authority is displayed in your results with the new rank_scale parameter in Backlinks API and Content Analysis API. This feature adds flexibility to how you work with backlink rank metrics.
What’s new?
With the new rank_scale parameter, you can choose between the default 0–1000 scale and the alternative simplified 0–100 scale for displaying Rank values. To specify your choice, use:
➤ one_thousand (default) – ranks remain on the 0–1000 scale.
➤ one_hundred – ranks are normalized to a 0–100 scale using our custom formula.
This setting applies to the rank, domain_from_rank, and pages_from_rank fields in the Backlinks API response and to the rank, url_rank, and domain_rank fields in the Content Analysis API.
Why it matters?
Switching to a 0–100 scale simplifies reporting, making it easier to present backlink data in your tools, dashboards, and reporting solutions. Whether you’re incorporating this data into client views or syncing with other systems using 0–100 metrics, this feature provides the clarity and control you may need in your workflows.
How does it work?
Behind the scenes, when you are using one_hundred, all rank values are normalized using this formula:
sin(rank / 636.62) * 100
For example, a domain rank of 694 (on the 0–1000 scale) becomes:
sin(694 / 636.62) * 100 = 88.6 which is then rounded to 89.
