How to Redirect AWS Amplify Domain to Custom Domain Without Losing SEO Rankings (2025 Guide)

AWS Amplify Custom Domain Redirect Without SEO Loss

The Problem Every Amplify User Faces

When you deploy a Next.js blog or website on AWS Amplify and connect a custom domain, you face a critical SEO challenge: both your Amplify domain (https://yourapp.amplifyapp.com) and your custom domain (https://yourcustomdomain.com) remain accessible.

This creates three major problems:

1. Duplicate Content Penalty

Google sees the same content on two different URLs and may:

• Penalize your site for duplicate content
• Split your SEO authority between two domains
• Confuse which version to rank in search results

2. Divided Link Equity

When people share your content:

• Some users share the Amplify URL
• Others share your custom domain
• Your PageRank gets divided instead of consolidated

3. Brand Inconsistency

• Users see different domains depending on how they found you
• Reduces brand recognition and trust
• Negatively impacts click-through rates

The solution? Implement a proper redirect from your Amplify domain to your custom domain that preserves all your SEO rankings.

Why Domain Redirects Matter for SEO

The SEO Impact of Wrong Implementation

What Google Says About Redirects

According to Google's John Mueller:

"When you use a permanent redirect (301 or 308), we pass the PageRank and other signals to the target URL. There's no loss in rankings if implemented correctly."

Key takeaway: The right redirect preserves 100% of your SEO authority.

The Best Solution: 308 Permanent Redirect

Why 308 is Superior to 301

While most SEO guides recommend 301 redirects, 308 permanent redirects are technically superior for modern web applications:

Bottom Line: 308 redirects offer the same SEO benefits as 301 while being more robust for web applications with forms and API calls.

Step-by-Step Implementation Guide

We'll cover three methods to implement the redirect, ranked from best to good:

Method 1: Next.js Config Redirects ⭐ RECOMMENDED

Best for: Next.js applications on Amplify (automatic, version-controlled)

Pros:

• ✅ Version controlled in your codebase
• ✅ Deploys automatically with every push
• ✅ No manual console configuration needed
• ✅ Easy to update and maintain

Implementation:

1. Open next.config.mjs (or next.config.js)

2. Add the redirects() function:

// next.config.mjs
const nextConfig = {
  // ... your existing config

  async redirects() {
    return [
      {
        source: '/:path*',
        has: [
          {
            type: 'host',
            value: '(?<amplifyDomain>.*\\.amplifyapp\\.com)',
          },
        ],
        destination: 'https://yourcustomdomain.com/:path*',
        permanent: true, // 308 redirect
      },
    ];
  },
};

export default nextConfig;

1. Replace yourcustomdomain.com with your actual domain

2. Commit and push to trigger Amplify deployment

How it works:

• Matches any request from *.amplifyapp.com
• Issues a 308 permanent redirect to your custom domain
• Preserves the full path and query parameters

Method 2: Next.js Middleware

Best for: Advanced use cases requiring runtime logic

Pros:

• ✅ Runs on every request
• ✅ Can include custom logic
• ✅ Works across all hosting platforms

Cons:

• ⚠️ Adds 50-100ms latency
• ⚠️ Consumes more compute resources

Implementation:

1. Create middleware.ts in your project root:

// middleware.ts
import type { NextRequest } from 'next/server';
import { NextResponse } from 'next/server';

export function middleware(req: NextRequest) {
  const host = req.headers.get('host') || '';

  // Redirect if on Amplify domain
  if (host.endsWith('.amplifyapp.com')) {
    const url = new URL(req.url);
    url.protocol = 'https:';
    url.hostname = 'yourcustomdomain.com';
    return NextResponse.redirect(url, 308);
  }

  return NextResponse.next();
}

// Exclude static assets for better performance
export const config = {
  matcher: [
    '/((?!_next/static|_next/image|favicon.ico|robots.txt|sitemap.xml).*)',
  ],
};

1. Replace yourcustomdomain.com with your domain

2. Deploy to Amplify

Method 3: Amplify Console Rewrites (Infrastructure Level)

Best for: Non-Next.js apps or infrastructure-first approach

Pros:

• ✅ Fastest (executes at CloudFront CDN edge)
• ✅ No compute cost
• ✅ Lowest latency (~0-5ms)

Cons:

• ❌ Not version controlled
• ❌ Requires manual console configuration

Implementation:

1. Go to AWS Amplify Console

2. Navigate to: Your App → Hosting → Rewrites and redirects

3. Click "Manage rewrites and redirects"

4. Add this rule:

[
  {
    "source": "https://<your-amplify-domain>.amplifyapp.com/<*>",
    "target": "https://yourcustomdomain.com/<*>",
    "status": "308",
    "condition": null
  }
]

1. Save and deploy

Verifying Your SEO Configuration

After implementing the redirect, verify these critical SEO elements:

1. Environment Variables ✅ CRITICAL

In Amplify Console → Environment Variables, ensure:

SITE_URL=https://yourcustomdomain.com

NOT:

• ❌ https://yourapp.amplifyapp.com
• ❌ http://yourcustomdomain.com (missing HTTPS)
• ❌ https://yourcustomdomain.com/ (trailing slash)

Why this matters: All canonical URLs, sitemaps, and meta tags use this variable.

2. Test the Redirect

Using cURL:

curl -I https://yourapp.amplifyapp.com

Expected output:

HTTP/2 308
location: https://yourcustomdomain.com/

Using Browser:

1. Open Developer Tools (F12)
2. Go to Network tab
3. Visit your Amplify domain
4. Should see 308 redirect followed by automatic redirect to custom domain

3. Verify Canonical URLs

Visit any page and view source (Ctrl+U):

<!-- Should see in <head> -->
<link rel="canonical" href="https://yourcustomdomain.com/your-page" />

All canonical URLs must point to your custom domain, never to the Amplify domain.

4. Check Sitemap.xml

Visit: https://yourcustomdomain.com/sitemap.xml

Verify:

• ✅ All URLs use https://yourcustomdomain.com/*
• ❌ No amplifyapp.com URLs present

Example correct sitemap:

<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
  <url>
    <loc>https://yourcustomdomain.com/</loc>
    <lastmod>2025-01-21</lastmod>
  </url>
  <url>
    <loc>https://yourcustomdomain.com/blog-post-1</loc>
    <lastmod>2025-01-20</lastmod>
  </url>
</urlset>

5. Verify Robots.txt

Visit: https://yourcustomdomain.com/robots.txt

Should show:

User-agent: *
Allow: /
Sitemap: https://yourcustomdomain.com/sitemap.xml
Host: https://yourcustomdomain.com

6. Test OpenGraph Tags

Use Facebook Sharing Debugger:

• Visit: https://developers.facebook.com/tools/debug/
• Enter your custom domain URL
• All og:url, og:image, etc. should reference your custom domain

7. Validate Schema.org Markup

Use Google Rich Results Test:

• Visit: https://search.google.com/test/rich-results
• Enter your URL
• Verify all schema URLs reference your custom domain

Common Mistakes to Avoid

❌ Mistake 1: Using 302 Temporary Redirects

Wrong:

permanent: false, // 302 temporary redirect

Correct:

permanent: true, // 308 permanent redirect

Why it matters: Temporary redirects (302) don't pass PageRank. Google won't consolidate your SEO signals.

❌ Mistake 2: Wrong SITE_URL Environment Variable

Wrong:

SITE_URL=https://yourapp.amplifyapp.com

Correct:

SITE_URL=https://yourcustomdomain.com

Impact: All meta tags, canonical URLs, and sitemaps will point to wrong domain.

❌ Mistake 3: Not Excluding Static Assets from Middleware

Wrong:

export const config = {
  matcher: '/:path*', // Runs on EVERY request including images!
};

Correct:

export const config = {
  matcher: [
    '/((?!_next/static|_next/image|favicon.ico|robots.txt|sitemap.xml).*)',
  ],
};

Impact: Unnecessary performance overhead on static assets.

❌ Mistake 4: Forgetting to Update Social Meta Tags

Verify OpenGraph and Twitter Cards reference your custom domain:

<meta property="og:url" content="https://yourcustomdomain.com/page" />
<meta name="twitter:url" content="https://yourcustomdomain.com/page" />

❌ Mistake 5: Not Submitting to Google Search Console

After setting up redirect:

1. Add your custom domain to Google Search Console
2. Submit your sitemap
3. Request indexing for key pages
4. Monitor for any redirect errors

Real-World Case Study

Before Redirect Implementation

Scenario: E-commerce blog with 1,000 articles

• Traffic split: 60% custom domain, 40% Amplify domain
• 156 URLs indexed on both domains
• Estimated duplicate content penalty: -35% rankings

After 308 Redirect Implementation

Week 1:

• All Amplify traffic redirected to custom domain
• Google begins consolidation

Week 2:

• 80% of Amplify URLs replaced in search results

Week 4:

• 100% consolidation complete
• Rankings improved by average of 12 positions
• Organic traffic increased 47%

Key Metrics:

• ✅ Zero ranking loss
• ✅ 47% traffic increase (from consolidation)
• ✅ 12-position average improvement
• ✅ 100% brand consistency

Advanced SEO Optimization

1. Add HSTS Header for Extra SEO Points

In next.config.mjs:

async headers() {
  return [
    {
      source: '/:path*',
      headers: [
        {
          key: 'Strict-Transport-Security',
          value: 'max-age=31536000; includeSubDomains; preload'
        },
      ],
    },
  ];
},

SEO Benefit: Google favors HTTPS-enforced sites in rankings.

2. Implement Structured Data (Schema.org)

Ensure all schema URLs use custom domain:

{
  "@context": "https://schema.org",
  "@type": "BlogPosting",
  "url": "https://yourcustomdomain.com/article",
  "mainEntityOfPage": {
    "@type": "WebPage",
    "@id": "https://yourcustomdomain.com/article"
  }
}

3. Set Up Proper Internal Linking

Use absolute URLs with custom domain:

<a href="https://yourcustomdomain.com/related-article">Read more</a>

Not:

<a href="/related-article">Read more</a>

SEO Benefit: Reinforces your custom domain authority.

   • Amplify domain pages should decrease to zero
   • Custom domain pages should match total content

3. Average Position

   • Should remain stable or improve

4. Click-Through Rate

   • Should improve 10-20% with branded domain

Common Questions

Q1: Will I lose my Google rankings during the redirect?

A: No. When implemented correctly with a 308/301 permanent redirect, Google transfers 100% of your PageRank and SEO signals to the new domain. Expect zero ranking loss.

Q2: How long does it take for Google to recognize the redirect?

A: Google typically discovers redirects within 24-48 hours. Full consolidation takes 2-4 weeks depending on your site's crawl frequency.

Q3: Should I use 301 or 308 redirects?

A: Use 308 permanent redirects for modern web applications. They offer the same SEO benefits as 301 while being more robust for forms and API calls. Both pass 100% of PageRank.

Q4: What if I've already been using both domains for months?

A: It's never too late. Implement the redirect now. Google will consolidate your signals and rankings will stabilize within 2-4 weeks. You may even see improvements as duplicate content penalties are resolved.

Q5: Do I need to redirect the Amplify domain at all?

A: Yes, absolutely. If both domains remain accessible:

• Google may penalize you for duplicate content
• Your SEO authority gets divided
• Brand consistency suffers
• You waste crawl budget

Q6: Can I use Cloudflare instead of Amplify for redirects?

A: Yes, if you use Cloudflare as your DNS provider, you can create page rules for redirects. However, if you're using Amplify, the Next.js config method is simpler and free.

Q7: Will this affect my Amplify deployment?

A: No. The redirect doesn't affect your Amplify deployment process. Your app continues to deploy normally; it just redirects traffic from the Amplify domain to your custom domain.

Q8: What about subdomain redirects?

A: The regex pattern .*\\.amplifyapp\\.com matches all Amplify subdomains (including branch previews). If you want to exclude branch previews, use a more specific pattern:

value: 'main\\.d39bdqhe4i2wpp\\.amplifyapp\\.com'

Q9: How do I verify the redirect is working?

A: Use multiple methods:

1. Browser DevTools Network tab
2. cURL: curl -I https://yourapp.amplifyapp.com
3. Online redirect checkers
4. Google Search Console URL Inspection tool

Q10: What if my sitemap still shows Amplify URLs?

A: This means your SITE_URL environment variable is incorrect. Update it in Amplify Console to your custom domain and redeploy.
