How the backlink checker works
SpiderDog connects to the DataForSEO Backlinks API to pull live backlink data for your domain. We cache results for up to seven days by default, so you are not charged for every report view, and we refresh the data on demand when you need the latest picture.
Backlink data is integrated directly into your audit reports, so you can correlate technical SEO issues with link quality and identify whether your strongest pages are also your healthiest pages.
The Backlink Add-on lets you increase the number of domains you can analyze each billing cycle. It shares the same billing period as your main plan and can be removed at any time.
Why backlink data matters
Backlinks remain one of the strongest signals search engines use to measure authority and relevance. A site with high-quality referring domains typically ranks faster and more consistently than a site with the same content but no links. Monitoring your backlink profile helps you identify new opportunities, spot lost links, and detect low-quality referrals that could harm your reputation.
SpiderDog combines backlink data with technical audit results so you can see whether your strongest pages are also your healthiest pages. This makes it easier to decide where to invest engineering and content resources for the biggest SEO impact.
