Site migration SEO is the process of moving a website to a new domain, platform, or URL structure while preserving existing search engine rankings and organic traffic. When done correctly, a migration can result in zero traffic loss and even improved rankings. When done poorly, businesses routinely lose 30–70% of their organic traffic overnight. This guide walks you through a proven migration framework used by agencies across India to protect search visibility during every type of site move.

What Is a Site Migration and Why Does It Affect SEO?
A site migration is any significant change to a website that affects its visibility in search engines. This includes domain name changes (e.g., moving from oldbrand.in to newbrand.in), platform switches (e.g., Wix to WordPress), URL structure changes, HTTP to HTTPS transitions, redesigns that alter page content and internal linking, or merging multiple sites into one.
Search engines have built trust signals around your current URLs over months or years. When those URLs change, Google must re-evaluate every page. Without proper 301 redirects and signal preservation, that trust evaporates and your rankings follow.
What Are the Different Types of Site Migrations?
| Migration Type | Example | SEO Risk Level |
|---|---|---|
| Domain change | myshop.in → myshop.com | High |
| Platform switch | Shopify → WooCommerce | High |
| URL restructure | /blog?id=123 → /blog/seo-guide/ | Medium-High |
| Protocol change | HTTP → HTTPS | Low-Medium |
| Redesign (same URLs) | New layout, same slugs | Low |
| Site merge | blog.brand.in + brand.in → brand.in | High |
Step-by-Step: How to Execute a Site Migration Without Losing Rankings
Step 1 — Pre-Migration Audit (2–4 Weeks Before)
Crawl your entire site using Screaming Frog, Sitebulb, or Ahrefs Site Audit. Export a full list of every URL, its title tag, meta description, H1, canonical tag, and internal links. Simultaneously pull your top-performing pages from Google Search Console — sort by clicks over the past 12 months. These are your priority pages.
Document current rankings for your top 50–100 keywords using a rank tracker. This gives you a baseline to compare against after migration.
Step 2 — Build a Complete Redirect Map
Create a spreadsheet with columns: Old URL, New URL, HTTP Status (301), Priority (high/medium/low based on traffic). Every single indexed URL must have a corresponding redirect. For Indian businesses with hundreds of product or location pages, this is often the most time-consuming step.
Rules for redirect mapping:
- Always use 301 (permanent) redirects, not 302.
- Map old URLs to the most relevant new URL — never redirect everything to the homepage.
- Preserve URL hierarchy where possible: /services/seo/ should still be /services/seo/.
- If a page is being removed, redirect to the closest topical equivalent.
- Avoid redirect chains (A → B → C). Every old URL should point directly to the final destination.
Step 3 — Set Up the New Site on Staging
Build the new site on a staging subdomain (staging.yourdomain.in) with a noindex meta tag. Replicate all critical on-page SEO: title tags, meta descriptions, H1 tags, image alt text, internal links, and schema markup. Run a parallel crawl of the staging site to compare against the production crawl.
Step 4 — Technical SEO Checklist Before Going Live
- XML sitemap updated with new URLs and submitted to Google Search Console
- Robots.txt allows crawling of all important pages (remove staging noindex)
- Canonical tags point to new URLs
- Hreflang tags updated (if multilingual)
- Structured data/schema updated and validated
- Internal links point to new URLs (not relying on redirects)
- Page speed optimized on new platform (target LCP under 2.5s)
- Mobile responsiveness tested across devices
Step 5 — Launch Day Execution
Go live during low-traffic hours (typically 2–5 AM IST for Indian businesses). Implement all 301 redirects simultaneously. Remove noindex directives. Submit the new sitemap to Google Search Console and Bing Webmaster Tools. Use the URL Inspection tool to request indexing of your top 20 pages.
Step 6 — Post-Migration Monitoring (4–12 Weeks)
Monitor Google Search Console daily for the first two weeks, then weekly. Watch for crawl errors, drops in indexed pages, and ranking changes. Check that redirects are working with a bulk redirect checker. Traffic dips of 10–20% in the first two weeks are normal and typically recover within 4–8 weeks.
How Much Does Site Migration Cost in India?
Professional site migration services in India typically range from ₹25,000 to ₹2,00,000 depending on complexity:
| Migration Scope | Estimated Cost (INR) | Timeline |
|---|---|---|
| Small site (under 50 pages) | ₹25,000–₹50,000 | 2–3 weeks |
| Medium site (50–500 pages) | ₹50,000–₹1,00,000 | 4–6 weeks |
| Large e-commerce (500+ pages) | ₹1,00,000–₹2,00,000+ | 6–12 weeks |
Common Site Migration Mistakes to Avoid
- Not creating a redirect map — the number-one cause of traffic loss.
- Redirecting everything to the homepage — Google treats this as a soft 404.
- Forgetting to update internal links — internal links should point to new URLs directly, not rely on redirects.
- Changing content and URLs simultaneously — isolate variables. Migrate first, then optimize content.
- Not monitoring after launch — many issues only surface after Google recrawls, which takes weeks.
- Ignoring backlink profiles — reach out to high-authority sites linking to you and request they update their links to the new URLs.
Frequently Asked Questions
How long does it take for rankings to recover after a site migration?
Most sites experience a temporary dip lasting 2–8 weeks. Well-executed migrations with proper 301 redirects typically recover within 4–6 weeks. Complex migrations involving domain changes and major content restructuring may take 3–6 months for full recovery.
Should I change my domain name and redesign my website at the same time?
No. Google recommends changing one thing at a time. If you must do both, migrate the domain first with the old design, wait for rankings to stabilize (6–8 weeks), and then redesign. This makes it easier to diagnose any issues that arise.
Do I need to notify Google about my site migration?
Yes. Use the Change of Address tool in Google Search Console for domain changes. For all migrations, submit the new XML sitemap, use the URL Inspection tool for priority pages, and ensure your 301 redirects are in place before launching.
What happens to my Google Business Profile during a domain migration?
Update the website URL in your Google Business Profile immediately after migration. GBP listings are tied to your business, not your domain, so your reviews and local rankings should remain intact as long as NAP details stay consistent.
Can I remove 301 redirects after the migration is complete?
Keep 301 redirects in place for at least one year, ideally permanently. Removing them too early causes 404 errors for any remaining backlinks pointing to old URLs and can result in traffic loss. The server overhead of maintaining redirects is negligible.
