Backlinks are one of the most important ranking factors for Google. But who monitors whether your hard-earned links still exist? Or whether competitors are building new links? In this guide, we show you how to fully automate backlink monitoring using tools like n8n and Make.com.

Typical Problems:

ProblemImpactAutomated Solution
Links disappear unnoticedRanking lossDaily check + alert
Competitors building linksCompetitive disadvantageCompetitor monitoring
New links not detectedMissed outreach opportunitiesReport new backlinks
Toxic links undiscoveredGoogle penalty riskAutomatic evaluation

Potential impact: A lost link from a DA60+ domain can drop rankings by 5-10 positions.

The Goal

Receive a report every morning:

  • New backlinks (last 24h)
  • Lost backlinks
  • Links with issues (became nofollow, etc.)

The Workflow

Schedule Trigger (daily 7:00 AM)
        |
    Ahrefs API: Get backlinks
        |
    Compare with yesterday
        |
    Identify new links
    Identify lost links
        |
    Create report
        |
    Send email/Slack

Implementation with n8n

Step 1: Call Ahrefs API

// Node: HTTP Request
{
  "method": "GET",
  "url": "https://api.ahrefs.com/v3/site-explorer/backlinks",
  "qs": {
    "target": "your-domain.com",
    "mode": "subdomains",
    "limit": 1000
  },
  "headers": {
    "Authorization": "Bearer YOUR_AHREFS_API_TOKEN"
  }
}

Step 2: Compare with previous day

// Node: Code
// Compare with stored data

const today = $json.backlinks;
const yesterday = $('Load Yesterday Data').item.json.backlinks;

const todayUrls = new Set(today.map(b => b.url_from));
const yesterdayUrls = new Set(yesterday.map(b => b.url_from));

const newLinks = today.filter(b => !yesterdayUrls.has(b.url_from));
const lostLinks = yesterday.filter(b => !todayUrls.has(b.url_from));

return {
  new: newLinks,
  lost: lostLinks,
  total: today.length,
  difference: today.length - yesterday.length
};

Step 3: Format report

// Node: Code
const report = `
# Backlink Report ${new Date().toLocaleDateString('en-US')}

## Summary
- Total: ${$json.total} backlinks
- Change: ${$json.difference > 0 ? '+' : ''}${$json.difference}

## New Backlinks (${$json.new.length})
${$json.new.map(l => `- [${l.domain_from}](${l.url_from}) - DR: ${l.domain_rating}`).join('\n')}

## Lost Backlinks (${$json.lost.length})
${$json.lost.map(l => `- ${l.domain_from} - Was: ${l.url_to}`).join('\n')}
`;

return { report };

Step 4: Notification

Node: Slack
- Channel: #seo-alerts
- Message: {{ $json.report }}

Node: Email (optional)
- To: seo-team@company.com
- Subject: Backlink Report {{ $now.format('MM/dd/yyyy') }}

The Goal

Get notified when competitors gain new backlinks - potential link opportunities for you.

The Workflow

Schedule (daily)
        |
    For each competitor:
      Ahrefs: New backlinks (24h)
        |
    Filter: Quality threshold (DR > 30)
        |
    Remove duplicates
    (links you already have)
        |
    Save opportunities to sheet
        |
    Send weekly digest

Define Competitors

// Node: Set
const competitors = [
  { domain: 'competitor1.com', name: 'Competitor 1' },
  { domain: 'competitor2.com', name: 'Competitor 2' },
  { domain: 'competitor3.com', name: 'Competitor 3' }
];

return { competitors };

Evaluate Opportunities

// Node: Code
// Calculate link opportunity score

const score = calculateScore(link);

function calculateScore(link) {
  let score = 0;

  // Domain Rating (0-100)
  score += link.domain_rating * 0.4;

  // Relevance (same industry)
  if (link.category === 'technology') score += 20;

  // Traffic of linking page
  if (link.traffic > 1000) score += 15;
  if (link.traffic > 10000) score += 10;

  // DoFollow bonus
  if (!link.nofollow) score += 15;

  return Math.round(score);
}

return {
  ...link,
  opportunityScore: score,
  priority: score > 70 ? 'HIGH' : score > 50 ? 'MEDIUM' : 'LOW'
};

The Goal

Detect when links to your site lead to 404 errors (e.g., because you changed a URL).

The Workflow

Schedule (weekly)
        |
    Get all backlinks
        |
    For each link: Check target URL
        |
    HTTP Status != 200?
        |
    Alert: "Set up redirect!"

HTTP Check

// Node: HTTP Request (for each backlink)
// HEAD request is faster than GET

{
  "method": "HEAD",
  "url": "{{ $json.url_to }}",
  "options": {
    "redirect": {
      "follow": false  // Don't follow redirects
    },
    "timeout": 10000
  }
}

Categorize Problems

// Node: Switch
const status = $json.statusCode;

if (status === 200) return { category: 'OK' };
if (status === 301 || status === 302) return { category: 'REDIRECT' };
if (status === 404) return { category: 'BROKEN' };
if (status >= 500) return { category: 'SERVER_ERROR' };

return { category: 'UNKNOWN' };

The Goal

Detect harmful backlinks before they endanger your rankings.

Criteria for Toxic Links

CriterionRisk
Domain Rating < 10Medium
Spam Score > 30High
Anchor text = "Viagra", "Casino"Very high
Link from link farmVery high
Suddenly 100+ links from one domainHigh

Automatic Evaluation

// Node: Code
function isToxic(link) {
  const redFlags = [];

  if (link.domain_rating < 10) redFlags.push('Low DR');
  if (link.spam_score > 30) redFlags.push('High Spam Score');

  const toxicAnchors = ['casino', 'viagra', 'porn', 'gambling'];
  if (toxicAnchors.some(t => link.anchor.toLowerCase().includes(t))) {
    redFlags.push('Suspicious Anchor');
  }

  // Link velocity check
  if (link.links_from_same_domain > 50) {
    redFlags.push('Link Farm Pattern');
  }

  return {
    isToxic: redFlags.length >= 2,
    redFlags,
    recommendation: redFlags.length >= 2 ? 'DISAVOW' : 'MONITOR'
  };
}

Generate Disavow List

// Node: Code
// Create Google Disavow format

const toxicLinks = $json.filter(l => l.isToxic);

const disavowFile = toxicLinks
  .map(l => `domain:${l.domain_from}`)
  .filter((v, i, a) => a.indexOf(v) === i)  // Unique
  .join('\n');

return {
  disavowFile,
  count: toxicLinks.length
};

Automatic Charts

With Google Sheets you can automatically create:

  • Backlink growth over time
  • DR distribution
  • Anchor text cloud
  • Top referring domains

Alert Configuration

Slack Alerts

// High Priority: Immediate
if (link.domain_rating > 60) {
  // Immediately to #seo-alerts
  await sendSlackMessage('#seo-alerts', `High-DR Link: ${link.domain_from} (DR${link.domain_rating})`);
}

// Medium Priority: Digest
if (link.domain_rating > 30) {
  // In daily report
  digestLinks.push(link);
}

// Low Priority: Just log
// Save to sheet, no alert

Email Digest Template

<h1>Backlink Report - {{ date }}</h1>

Best Practices

1. Focus on Quality

Not every backlink is equally valuable:

  • DR > 50: Immediate alert
  • DR 30-50: Daily digest
  • DR < 30: Weekly report

2. Understand Context

// Analyze link context
const isEditorial = !link.sponsored && !link.ugc;
const isRelevant = link.category === yourCategory;
const hasTraffic = link.traffic > 100;

const qualityScore = (isEditorial ? 30 : 0) +
                     (isRelevant ? 30 : 0) +
                     (hasTraffic ? 20 : 0) +
                     (link.domain_rating * 0.2);

3. Keep Historical Data

// Save snapshot every day
const snapshot = {
  date: new Date().toISOString(),
  totalBacklinks: backlinks.length,
  totalDomains: uniqueDomains.length,
  averageDR: avgDR,
  backlinks: backlinks
};

// Save to database/Google Sheets

Conclusion

Automated backlink monitoring gives you:

  • Early warning system for lost links
  • Competitor insights for new opportunities
  • Protection from toxic links
  • Time savings: 5-10 hours/week

Next Steps
