What You Get

OpenPageRank score (0–100)

Authority score for your domain, fetched on every scheduled run. Built on Common Crawl, free for everyone.

Pulse on change

Slack or email alert only when the score actually moves — no daily noise. UNCHANGED runs are silenced automatically.

Ahrefs DR backfill (optional)

If you have Ahrefs connected, optionally seed the chart with 90 days of historical Domain Rating values when adding a domain.

Backlinks & referring domains (paid)

Total inbound link count and unique referring-domain count, charted over time. Coming on paid plans via DataForSEO.

How It Works

One click — no OAuth, no API key. Chartcastr fronts the upstream data cost.

Just the bare hostname (example.com). We fetch your authority score on the schedule you choose.

3Pulses to Slack or email

When the score moves, you get a notification with the chart attached. AI summary explains the delta.

Pairs with Other Sources

Add OpenPageRank to a Source Group with Plausible, Google Search Console, or Shopify, and Chartcastr's AI correlates the metrics across them — “score held steady but organic clicks dropped” or “score up, revenue flat” — surfaced automatically in the pulse.
