Backlink Catalog is a lightweight web-based tool that monitors backlinks, tracks Domain Authority (DA), Page Authority (PA), and Spam Score, and sends email alerts when a backlink changes or is removed.
What is Backlink Catalog?
Backlink Catalog is a backlink monitoring service that allows users to add known backlinks or automatically detect them. It outputs real-time DA, PA, and Spam Score metrics for each link, and sends email notifications when a backlink's metrics drop, the link is removed, or its attributes change (e.g., to nofollow). The tool is entirely web-based, requires no installation, and is developed by an independent team (no company name is disclosed on the site).
