Link Signals is for site owners, agencies and SEOs, and for publishers with large archives of older content, where outbound links go stale or change hands without anyone noticing.
What it checks
- Sitemap-based scanning, including sitemap indexes and compressed files
- Hidden links (seven CSS techniques), cloaked links and script-written links
- Expired or unregistered domains, parked domains and domains that have changed use
- Matches against a blocklist of more than 63,000 adult and gambling domains
- A model-based judgment of whether a link fits its destination and the page it appears on
What you get
Verdicts say how each finding was reached, and keyword-only or model-only flags are marked “Needs review” so a person makes the call. Reports can be saved and exported as CSV, and paid plans add monitoring with email alerts. There is a free plan to start with.
How it works
Link Signals reads the sitemap, collects outbound links with their anchor text, fetches the destinations like a browser, checks domain registry data, matches against blocklists, and then uses a model to assess relevance. It reads public pages only and identifies itself as LinkSignalsBot.
Limits, as stated: it cannot see links behind a login, and links built only while scripts run may be missed.
