Introduction

Website migration can be an exciting yet challenging phase in a business’s online journey. While it brings improved functionality, design, and user experience, post-migration technical SEO is often overlooked. If not properly managed, hidden errors can severely impact your search engine rankings, leading to a loss of organic traffic. In this guide, we’ll explore the key steps involved in technical SEO post-migration and how to identify and fix those sneaky hidden errors that can hurt your site’s performance.


What is Technical SEO Post-Migration?

Technical SEO post-migration refers to the technical changes that need to be implemented after migrating your website to a new platform, domain, or structure. Migration can be a complex process that involves URL changes, content relocation, and system upgrades. It’s crucial to monitor and fix any technical issues that arise during this period to ensure that your SEO rankings are not negatively affected.


Why Technical SEO Post-Migration Matters

When you migrate your website, whether it’s moving to a new domain or redesigning the site, you need to prioritize technical SEO post-migration to avoid SEO setbacks. Failure to perform this check could result in missing URLs, broken links, or improper redirects—all of which could negatively affect your rankings and visibility in search engines.


Common Post-Migration SEO Errors to Look For

There are several common post-migration SEO errors that you may encounter after completing your website migration. These issues can often go unnoticed if you’re not vigilant. Here are the top errors to watch out for:

Broken Links and 404 Errors

Broken links are one of the most prevalent website migration issues that can harm your SEO. After migration, URLs might change, which means that your internal and external links can break, resulting in 404 errors. It’s essential to fix these broken links by implementing proper redirects.

Missing Redirects

Without proper redirects in place, search engines will struggle to find your new pages. If a user attempts to visit an old URL, they will be met with a 404 error. Redirects should be set up to seamlessly guide users from old URLs to new ones. Missing or incorrect redirects can be detrimental to your site’s SEO.

Incorrect Sitemap

Post-migration, your sitemap may no longer reflect your site’s new structure, which can cause confusion for search engines. Make sure to update and resubmit your sitemap to ensure that search engines can crawl and index your pages correctly.


How to Find and Fix Hidden Technical SEO Errors

Identifying hidden technical SEO errors after migration is crucial to maintaining your rankings. Here’s how to perform a thorough post-migration SEO audit:

  1. Run a Site Crawl Use tools like Screaming Frog, Ahrefs, or Google Search Console to run a comprehensive crawl of your site. This will help you spot 404 errors, broken links, and missing redirects. Running a crawl regularly can give you a snapshot of your site’s SEO health.

  2. Check for Duplicate Content Migration often causes duplicate content issues when new URLs are indexed or when content from multiple pages is combined. Use canonical tags to point search engines to the preferred version of your content.

  3. Review Your Robots.txt File A robots.txt file can accidentally block search engines from crawling key areas of your site. After migration, verify that your robots.txt file is correctly configured to allow search engine bots to crawl essential parts of your website.

  4. Monitor Page Load Speed Website performance plays a significant role in SEO. Migration can affect your site’s loading speed, which may cause a negative user experience and lower rankings. Use Google PageSpeed Insights to identify slow-loading pages and fix them promptly.


Fixing SEO Issues After Migration

Once you’ve identified the technical SEO issues, it’s time to fix them. Here’s how to tackle the most common problems:

Implement Redirects Correctly

For URLs that have changed, you need to set up 301 redirects from the old URL to the new one. This ensures that both users and search engines are directed to the correct pages. Avoid using 302 redirects, as they are temporary and don’t pass the full SEO value.

Update Internal Links

After migration, it’s common for internal links to point to old URLs. You need to manually update all internal links to ensure they point to the new URLs. This will prevent users from encountering 404 errors.

Fix Site Structure Issues

Ensure that your site structure is logical and user-friendly. A disorganized site can cause problems for both users and search engines. Improve your navigation, enhance internal linking, and use clear hierarchies.
