DA PA Checker

Authority scores are shown in the browser by DA PA Checker, a free SEO toolbar that reports Domain Authority, Page Authority, Spam Score and Domain Rating, and keeps a history of past checks. It is designed for quick lookups while browsing Chrome, replacing trips to a separate website for each domain. The experience is kept focused on fast checks, saved history and easy access to related tools, without the complexity of a large SEO platform. It suits anyone who regularly vets domains for partnerships, outreach or competitor comparison and wants those numbers on hand as a lightweight extension.
