A Domain Authority Checker brings several SEO estimates together so you can assess a website with more context. This DA checker shows domain authority, page authority, spam score, and total backlinks when the data provider supplies them.
What is DA?
DA stands for Domain Authority. It is a third-party score, usually from 0 to 100, that estimates the relative strength of an entire domain. A higher score can suggest a stronger backlink profile, but DA is not a Google ranking factor.
A Domain Authority Checker helps you compare domains at a glance. Use a DA checker to spot broad differences, then review the sites themselves before making an SEO decision.
What is PA?
PA stands for Page Authority. It estimates the relative strength of an individual page on a 0 to 100 scale. A domain can have a strong DA while one of its pages has a lower PA, because the two scores describe different levels of a site.
PA is useful when comparing specific pages, such as pages competing for the same topic or pages you are considering for a backlink.
What is SS?
SS stands for Spam Score. It is an estimate of signals that may be associated with low-quality or spammy websites. A higher percentage suggests that a closer review is sensible; it does not prove that a site is unsafe or penalized.
Read SS alongside the site's content, links, and relevance instead of treating it as a final verdict.
