Link Intelligence & Curation

The curated link graph for high-signal discovery.

NDAGLinks indexes the live web's editorial link graph, scores every destination by trust, topical relevance, and editorial standards, and surfaces the 1.4% of URLs worth linking to. We do in 30 seconds what a junior SEO spends 4 hours doing — and we do it without recycling the same DR-90 list every competitor is already pitching.

The mechanism

SignalScore is the four-input composite that filters 2.3 billion links down to the 1.4% worth pitching.

Legacy tools hand you a Domain Rating and a list. We score every destination against four weighted inputs so the URLs at the top of your queue are the ones a senior editor would actually accept.

Read the full methodology
  1. 01Domain Authority30%

    A normalized authority signal calibrated against editorial publications — not a raw backlink count.

  2. 02Topical relevance28%

    Semantic match between your source page and the destination's editorial beat, scored at the URL level.

  3. 03Editorial standards24%

    A pass/fail review of editorial policy, fact-checking rigor, byline transparency, and link-out hygiene. 74% of "high DR" domains in competitor tools fail this check.

  4. 04Outbound-link velocity18%

    How often a destination actually links out to fresh sources — a proxy for how often it will link to you.

The daily workflow

Four moves that replace four hours of junior SEO gruntwork with thirty seconds.

NDAGLinks is built around the loop SEO strategists actually run every morning. Each step cuts the time between "I need a link" and "I have a pitchable target."

  1. 01

    Prospect — generate candidates in seconds.

    Drop in a source URL or a topic. NDAGLinks returns the live destinations that actually link to comparable content, ranked by SignalScore and filtered for editorial fit. The DR-90 spam list never appears.

    Time: 4 minutes · vs. 90 minutes manually

  2. 02

    Vet — kill the bad pitches before they ship.

    Each candidate comes with editorial-standards scoring, recent outbound velocity, topical context, and a one-click duplicate check against your CRM. Red flags surface in the queue, not after the rejection email.

    Time: 6 minutes · vs. 75 minutes in spreadsheets

  3. 03

    Pitch — pull the contact, write the angle.

    Verified editor bylines, recent coverage, and a tone-matched pitch brief generated from the destination's last ten articles. Open rates on outbound from NDAGLinks briefs average 41%.

    Time: 11 minutes · vs. 80 minutes of research

  4. 04

    Track — close the loop without a spreadsheet.

    Every pitch lives in a workspace with status, response time, and live link status. The 15-minute index refresh picks up your placement within the hour — no weekly "did it go live?" check.

    Time: 3 minutes · vs. 25 minutes of manual checks
