Website Migration: How To Do It Correctly Without Ruining Your SEO

Introduction

Website migration can be a daunting task. Whether you are rebranding, switching platforms, or improving your site’s structure, the process involves risks that can harm your SEO performance if not done correctly. Protecting your search engine rankings is critical to maintaining visibility and traffic. This guide will walk you through how to conduct a successful website migration without jeopardising your SEO.

1. What is Website Migration?

Website migration refers to significant changes made to a website that can affect its performance, structure, or location. These changes often require updates to the underlying code, design, or domain setup, making it vital to handle them carefully.

Website migration can involve a variety of scenarios, each with its own set of challenges and opportunities:

• Changing Domain Names: This is common during rebranding or after acquiring a new business. It requires careful planning to ensure existing backlinks and SEO signals are preserved.
• Switching to a New Hosting Provider: Upgrading to a faster or more reliable hosting service can improve site performance but needs seamless DNS updates and uptime monitoring.
• Replatforming or Redesigning: Whether moving to a new content management system (CMS) or enhancing your site’s design, this type of migration often impacts site structure and content layout.
• Moving to HTTPS: Migrating to a secure HTTPS protocol enhances user trust and is a recognised ranking factor by search engines.

Understanding the type of migration you are undertaking helps in creating a tailored strategy to address its unique challenges.

2. Why Website Migration Impacts SEO

Website migration directly affects how search engines interpret your site. Search engines rely on signals like URLs, content structure, and links to understand and rank your website. Significant changes in these signals can cause:

• Loss of Traffic: If redirects are not properly implemented, visitors may land on broken pages, leading to a decline in organic traffic.
• Broken Links: Internal and external links can become outdated, harming the user experience and your SEO performance.
• Ranking Drops: Search engines may temporarily or permanently devalue your site if they encounter issues during migration, such as duplicate content, missing metadata, or crawling errors.

To mitigate these risks, it is essential to adopt a proactive approach to SEO during the migration process.

3. Pre-Migration Preparations

Thorough preparation is crucial to minimise the risks of website migration. Here are the key steps to follow:

Conducting a Website Audit

Start with a detailed audit of your existing website. Tools like Google Analytics, SEMrush, or Ahrefs can help you gather valuable insights into:

1. Traffic Sources: Understand which pages bring in the most traffic and from which channels.
2. Backlinks: Identify pages with high-quality backlinks that need to be preserved.
3. Keyword Rankings: Document the current keyword performance of your site’s pages.

Creating a Migration Checklist

Develop a comprehensive checklist covering every step of the migration process, including:

• Preparing technical updates.
• Creating a content strategy.
• Planning testing phases post-migration.

This checklist will serve as your roadmap to ensure no critical tasks are overlooked.

Backing Up Your Website

Create a complete backup of your website, including all files, databases, and configurations. This ensures you can restore the original site if anything goes wrong during the migration.

Setting Clear Goals for the Migration

Define what you want to achieve, whether it’s better site performance, improved user experience, or enhanced branding. These goals will shape your migration strategy.

4. Mapping and Redirect Strategy

URL mapping and redirects are at the core of a successful migration. If mishandled, they can lead to broken links and SEO penalties.

Creating a URL Mapping Plan

Map existing URLs to their new counterparts to maintain continuity. Use a spreadsheet to document old URLs alongside their corresponding new ones. This ensures no URL is left unmapped, preserving link equity and user experience.

Implementing 301 Redirects

Implement 301 redirects to permanently point old URLs to their new locations. Follow these best practices:

• Avoid Redirect Chains: Always redirect directly to the final URL to minimise loading times and avoid confusion for search engines.
• Test Redirects Thoroughly: Use tools like Screaming Frog or redirect checkers to ensure all mappings are functional.

5. Technical Considerations During Migration

Technical SEO elements require close attention to ensure your site remains crawlable and indexable during migration.

Updating Site Architecture and Internal Linking

Revisit your site architecture to maintain a logical and user-friendly structure. Update all internal links to reflect the new URL structure and ensure no orphaned pages are left behind.

Checking Robots.txt and Sitemap Files

Verify your robots.txt file does not block important areas of your site. Update your XML sitemap with the new URLs and submit it to search engines to help them index your site efficiently.

Ensuring Mobile-Friendliness

With mobile-first indexing, ensuring your site is mobile-friendly is critical. Test your site’s mobile performance using Google’s Mobile-Friendly Test tool.

SSL Certificates and HTTPS Migration

If you’re migrating to HTTPS, install and properly configure an SSL certificate. Update all internal links to HTTPS and verify the implementation to avoid mixed content warnings.

6. Content Management During Migration

Content plays a pivotal role in SEO. It’s essential to manage your site’s content carefully during migration.

Preserving Existing Content Structure

Ensure high-performing content retains its structure, including headings, metadata, and keyword placement. This preserves its SEO value and prevents ranking losses.

Optimising New Content

As you migrate, review and optimise content for:

• Relevant keywords.
• Descriptive and engaging meta titles and descriptions.
• Proper use of heading tags (H1, H2, etc.) to maintain readability and SEO.

Handling Duplicate Content Issues

Use canonical tags to consolidate duplicate content signals and indicate the primary version of a page to search engines.

7. Testing Your Website Post-Migration

Testing is a critical step in ensuring a smooth transition. Run a comprehensive post-migration check to identify and resolve potential issues.

Using Tools to Test Functionality

Use tools like Google Search Console and Screaming Frog to identify and address:

• Broken links.
• Missing or duplicate metadata.
• Crawl errors.

Validating Redirects and Fixing Broken Links

Run site-wide checks to ensure all redirects function correctly and update any broken links promptly. This helps maintain a positive user experience and preserves link equity.

8. Post-Migration SEO Best Practices

SEO efforts don’t stop once the migration is complete. Follow these best practices to maintain performance:

Monitoring Website Performance Metrics

Keep an eye on key metrics like:

• Organic traffic.
• Keyword rankings.
• Bounce rates and conversion rates.

Submitting an Updated Sitemap to Search Engines

Submit your updated sitemap to Google Search Console and Bing Webmaster Tools to help search engines crawl and index your new site structure.

Checking for Crawl Errors and Fixing Them

Regularly review crawl reports for errors and address them promptly to ensure optimal site performance.

9. Common Website Migration Mistakes and How to Avoid Them

Ignoring SEO Impact During Planning

Failing to involve SEO professionals in the planning stage can lead to significant traffic loss. Ensure SEO is a priority from the outset.

Skipping Testing Phases

Thorough testing is non-negotiable. Skipping this step increases the likelihood of unnoticed errors impacting site performance.

Overlooking Technical SEO Aspects

Pay attention to technical details such as redirects, mobile-friendliness, and crawlability. These are foundational to a successful migration.

Equip yourself with reliable tools like Google Analytics, Screaming Frog, SEMrush, and Ahrefs to streamline the migration process. Learn from case studies and best practices to avoid common pitfalls and adopt proven strategies.
