# Site Strength

> Get Site Strength, Rankfield's 0–100 authority score for a domain, calculated from the Rankfield web graph.

Site Strength rates how strongly the rest of the web links to a domain, on a 0–100 scale. It comes from the domain's ranks in the Rankfield web graph, so you can compare any two domains in the graph the same way.

One request returns one score. There are no per-key limits.
