How fresh is this data?
This page reflects the Apr-Jun 2026 Common Crawl hyperlink-graph release. Common Crawl publishes a new graph every ~3 months; we re-index within a few days of each release.
Want to compare up.pt to a competitor?
Use gap analysis to find domains that link to a competitor but not to up.pt - the highest-leverage outreach list you can build.
Do I need an Ahrefs or Semrush subscription to see this?
Not for referring domains and link gaps - both come from the open Common Crawl graph this page runs on. The paid suites still win on live re-crawl, rank tracking and keyword research, so we put them side by side tool by tool in the SEO tool alternatives comparison (Ahrefs, Semrush).
