Website Migration SEO Validation
Verify SEO elements are preserved during site migrations
Website migrations often damage search rankings when SEO elements are misconfigured. EdgeDNS validates critical SEO infrastructure to catch issues before they impact traffic.
The Challenge
Website migrations and platform changes frequently cause SEO disasters. Redirects break, canonical tags point to wrong URLs, sitemaps reference old pages, and meta tags get lost. These issues can take months to recover from and cause significant traffic and revenue loss.
The Solution
Run automated SEO validation checks against your staging environment before migration. Verify redirects resolve correctly, canonical URLs are properly set, sitemaps are accessible, and meta tags are present. Compare pre and post-migration to catch regressions.
Endpoints Used
Combine these EdgeDNS endpoints to build this solution.

Code Example
SEO validation for website migration
async function validateMigrationSEO(urls) {
const headers = { 'Authorization': 'Bearer YOUR_API_KEY' };
const issues = [];
for (const url of urls) {
const domain = new URL(url).hostname;
const [canonical, meta, sitemap] = await Promise.all([
fetch(`https://api.edgedns.dev/v1/domain/canonical?url=${url}`, { headers }),
fetch(`https://api.edgedns.dev/v1/domain/meta?url=${url}`, { headers }),
fetch(`https://api.edgedns.dev/v1/domain/sitemap?domain=${domain}`, { headers }),
].map(p => p.then(r => r.json())));
// Check canonical points to self or correct URL
if (canonical.data.canonical && canonical.data.canonical !== url) {
issues.push({ url, issue: `Canonical mismatch: ${canonical.data.canonical}` });
}
// Verify critical meta tags exist
if (!meta.data.title) {
issues.push({ url, issue: 'Missing title tag' });
}
if (!meta.data.description) {
issues.push({ url, issue: 'Missing meta description' });
}
}
// Check sitemap accessibility
const sitemapCheck = await fetch(
`https://api.edgedns.dev/v1/domain/sitemap?domain=${new URL(urls[0]).hostname}`, { headers }
).then(r => r.json());
if (!sitemapCheck.data.accessible) {
issues.push({ url: 'sitemap.xml', issue: 'Sitemap not accessible' });
}
return { passed: issues.length === 0, issues };
