Seowl

SEOwl is a web-based SEO monitoring platform that tracks keyword positions, on-page changes and backlinks in one place. Its rank tracker includes SERP Diff, which compares the top results for a keyword between two dates. Page monitoring crawls pages as often as every hour and flags changes before rankings are hit, with a set of checks and alerts by in-app notice, email or Slack. The backlink monitor crawls links daily to confirm each one is still live, dofollow and indexed, and helps organize link building work. White-label reports come from a drag-and-drop designer, and each project has a read-only sharing link. A RESTful API supports integration. Free tools include a bulk keyword rank checker, a bulk Google index checker and a sitemap extractor, and a free trial needs no credit card.
