TL;DR
A drop in website traffic after a web migration is a common but stressful event, typically caused by technical SEO errors. The most frequent culprits are incorrect 301 redirects, indexing problems like a 'noindex' tag left on the live site, or lost on-page content and metadata. Recovering your traffic requires a systematic post-migration audit to diagnose these issues, followed by methodical fixes and patient monitoring as search engines re-process your updated site.
Diagnosing the Traffic Drop: A Step-by-Step Post-Migration Audit
After a web migration, the first step toward recovery is a thorough diagnosis. A post-migration SEO audit is a comprehensive review to ensure search engines can still find, crawl, and rank your site effectively. Skipping this step is one of the biggest mistakes a business can make, potentially leading to a catastrophic loss of organic traffic and keyword rankings built over years. The process involves methodically checking every connection to make sure your customers—and Google—can find your new digital address without interruption.
Your audit should be structured around three core areas: Technical SEO, On-Page & Content Integrity, and Performance Monitoring. This systematic approach helps you pinpoint exactly what broke during the transition so you can apply the right fixes. Before you begin, it's crucial to have pre-migration data, including a full website crawl of old URLs and exports from Google Analytics and Google Search Console (GSC), to use as a baseline for comparison.
Technical SEO Checklist
Technical issues are the most common cause of post-migration traffic loss. This is the foundation of your site's visibility, and even small errors can have a massive impact.
- Verify Indexing Settings: Check your robots.txt file to ensure you aren't blocking important pages from being crawled. Crucially, verify that your pages do not have a 'noindex' meta tag. Developers often use this tag on a staging site and forget to remove it upon launch, which tells Google to remove your entire site from its index.
- Confirm 301 Redirects: This is perhaps the most critical check. Every URL from your old site must have a permanent 301 redirect pointing to its direct equivalent on the new site. Use a crawling tool to check for redirect chains (e.g., Page A redirects to B, which redirects to C) or loops (Page A redirects to B, which redirects back to A), as these waste crawl budget and can dilute link equity.
- Check Canonical Tags: Ensure that canonical tags on your new pages are self-referencing or point to the correct primary version to prevent duplicate content issues. An incorrect canonical tag can tell Google to ignore a page in favor of another.
- Submit New XML Sitemap: Create and submit an XML sitemap with all your new URLs to Google Search Console. This helps Google discover and index your new pages more quickly. According to an expert tip from The Gray Company, you can also submit a temporary sitemap of your OLD URLs to help Google find and process the 301 redirects faster.
On-Page and Content Integrity
Even if your site is technically sound, changes to your content can cause rankings to drop. The migration process can sometimes strip out or alter critical on-page elements.
- Audit Metadata: Compare a new crawl of your live site with your pre-migration crawl. Check that all meta titles and descriptions have been transferred correctly. Placeholder titles like "Home" or "Product Page" provide no SEO value and must be corrected.
- Verify Heading Structure: Ensure the heading hierarchy (H1, H2, H3) has been maintained. The H1 tag is a strong relevance signal, and its absence or incorrect implementation can negatively affect rankings.
- Check for Broken Internal Links: Crawl the new site to find and fix any broken internal links. All links should point directly to the new 200-status URLs, not to old URLs that then redirect.

Core Recovery Actions: Fixing Redirects, Indexing, and Content Issues
Once your audit has identified the problems, it's time to take corrective action. The key is to work methodically, prioritizing the most critical issues first. Indexing and redirect problems should be at the top of your list, as they have the most immediate and severe impact on your site's visibility. Think of this as digital triage: stop the bleeding before you address the smaller wounds.
For instance, if you discovered a 'noindex' tag on your live site, removing it is the absolute first priority. This simple fix allows search engines to begin re-indexing your pages. Similarly, broken 301 redirects are a major leak in your SEO foundation, preventing valuable link equity from flowing to your new pages. Fixing these ensures that the authority your old site built up is properly transferred. A detailed guide from Shopify emphasizes that acting within a couple of weeks is crucial for a successful recovery.
A Prioritized Fix-It Plan
- Fix Indexing Issues: If your robots.txt file is blocking crawlers or you have 'noindex' tags on live pages, correct these immediately. Change 'noindex' to 'index' and remove any prohibitive 'Disallow' rules in your robots.txt file. Submit the updated file and request re-indexing in Google Search Console.
- Implement Correct 301 Redirects: Ensure all redirects are permanent (301) and not temporary (302). A 301 redirect tells search engines the move is permanent and that they should pass along link equity. You can implement these rules via your CMS or directly in your server's .htaccess file. For example, a simple redirect rule might look like this:
Redirect 301 /old-page.html https://www.yournewsite.com/new-page/ - Restore Lost Content and Metadata: Using your pre-migration crawl data as a reference, systematically go through your most important pages and restore any missing or altered meta titles, descriptions, and H1 tags. This ensures that the signals you send to Google about each page's topic remain consistent.
- Update Internal and External Links: While fixing redirects is critical, you should also update your internal links to point directly to the new URLs. This improves user experience and crawl efficiency. For your most valuable backlinks, consider reaching out to the linking websites and asking them to update the URL to point directly to your new page.
As you work to restore and optimize your on-page content, it's also an opportune moment to evaluate its overall quality and plan for future growth. For marketers and creators looking to scale their content production with high-quality, SEO-optimized articles, platforms like BlogSpark can revolutionize the workflow, helping to turn new ideas into engaging posts efficiently and ensuring your content strategy supports long-term traffic recovery and growth.
The Road to Recovery: Setting Timelines and Monitoring Progress
After implementing fixes, the next phase is one of the most difficult: waiting. SEO recovery after a web migration is rarely instantaneous. It can take several weeks, or in some severe cases, many months for Google to recrawl all the old URLs, process the thousands of redirects, and re-evaluate the new pages to assign them their proper rankings. Managing your expectations during this period is critical to avoid making reactive, unnecessary changes that could further complicate the situation.
A compelling case study from Hooshmand.net documents a painful but realistic recovery journey that took over 1.5 years. The site's traffic plummeted by 90% after what seemed to be a technically sound domain migration. The recovery was not a smooth upward line but a series of frustrating fluctuations, with periods where Google appeared to be 'testing' the new site by showing it for certain keywords before it would disappear again. This illustrates a crucial point: patience, grounded in the knowledge that you have completed a thorough audit and fix process, is your most important tool.
During this time, Google is essentially rebuilding its understanding of your website. Don't be alarmed by volatility in your analytics; it's often a sign that the re-evaluation process is underway. The immediate goal is not necessarily to increase traffic beyond previous levels but to first recover what was lost. Once stability returns, you can focus on growth.
Your Post-Fix Monitoring Checklist
Instead of anxiously watching your traffic stats every hour, focus on a structured monitoring plan to track progress and spot any new issues that may arise. This gives you a sense of control and ensures you are looking at the right signals.
- Daily: Check Google Search Console for new crawl errors. Look for spikes in 404s (Not Found) or 5xx (Server Error) messages in the Index Coverage report. A sudden increase can indicate a new problem that needs immediate attention.
- Weekly: Track keyword rankings for your top 20-50 pages. Monitor the positions of your most valuable keywords. You are looking for a gradual upward trend over several weeks. Don't panic over daily fluctuations.
- Weekly: Monitor the Index Coverage report. Watch for the number of 'Valid' indexed pages to increase as Google crawls your new site. Concurrently, you should see pages from your old domain begin to drop out of the index.
- Monthly: Compare organic traffic year-over-year. To account for seasonality, compare your current month's traffic to the same month from the previous year. This gives you a more accurate picture of your recovery progress.
Frequently Asked Questions About Web Migrations
1. Why is my website losing traffic after a migration?
Traffic loss after a migration is almost always due to technical SEO issues. The most common causes include: improperly implemented 301 redirects (or using 302s by mistake), failing to remove 'noindex' tags from the live site, an incorrect robots.txt file blocking search engine crawlers, lost metadata (like title tags and meta descriptions), or significant changes to on-page content that alter keyword relevance.
2. Will a domain migration increase my SEO traffic?
Not directly or immediately. The primary goal of a migration is to retain your existing SEO value, not instantly increase it. While a better domain name might improve brand trust and click-through rates over the long term, the migration itself does not provide a direct SEO boost. When done correctly, the goal is for search engines to fully adjust to the changes and restore your previous traffic levels. Growth can come later, once the new site is stable.
3. What happens when you migrate a website?
Website migration refers to any significant sitewide change that can impact search engine visibility. This can include moving to a new domain, switching hosting providers, changing your CMS platform (e.g., from WordPress to Shopify), or launching a major redesign. In each case, URLs, site structure, or content are often altered, requiring search engines to re-crawl and re-evaluate your entire site. This process carries the risk of losing rankings if not managed carefully with a detailed SEO plan.
