The list covers various aspects of website migration, from pre-migration planning to technical, on-page, and off-page SEO, testing, and post-migration monitoring and maintenance. By following this checklist, you can minimize the risk of losing search engine rankings and ensure the long-term success of your website.

Pre-Migration Planning

A successful website migration starts with thorough planning. Before diving into the migration process, it’s essential to lay a solid foundation by completing the following tasks:

Identifying the reasons for migration

Understanding the primary reasons for migrating your website is crucial. Common reasons include:

  1. Rebranding or changing the domain name
  2. Switching to a new content management system (CMS)
  3. Updating the site’s structure or design
  4. Migrating to a new web host or server

Assembling the migration team

Assemble a team of experts with diverse skill sets, such as project managers, developers, designers, content creators, and SEO specialists. This team will execute the migration plan and ensure the website’s performance doesn’t suffer.

Establishing a timeline

Create a detailed timeline for your migration project. This will help keep the team on track and ensure all tasks are completed in the proper order. Make sure to factor in time for testing and troubleshooting.

Conducting a thorough website audit

Before starting the migration, conducting a comprehensive website audit is essential. This will help you understand your website’s current state and identify any issues that need to be addressed during the migration process. Key areas to audit include:

  1. Technical SEO: Analyze your site’s structure, URL structure, redirects, and other technical elements.
  2. On-Page SEO: Evaluate your site’s content, meta tags, header tags, and other on-page factors.
  3. Off-Page SEO: Assess your site’s backlink profile, social media presence, and local listings.
  4. User Experience (UX): Determine how easily users can navigate and interact with your site.

Armed with this information, you can create a prioritized list of improvements and develop a strategy for implementing them during migration. This will ensure that your new website retains its existing search engine rankings and provides an opportunity for further growth and improvement.

Technical SEO Checklist

Technical SEO is a critical aspect of website migration, as it directly impacts search engine crawling, indexing, and ranking. Addressing technical SEO issues during migration will help ensure your new site performs optimally in search results.

URL structure and redirects

  1. Creating a URL mapping document: Document the old and new URLs for all pages on your website, considering any changes in site structure, categories, or slugs. This mapping document will be the foundation for implementing redirects and monitoring post-migration performance.
  2. Implementing 301 redirects: Set up 301 redirects from old URLs to their corresponding new URLs. This will help preserve your site’s link equity, maintain user experience, and prevent search engines from indexing outdated URLs.

Website structure and internal linking

Ensure your new site’s structure is easy for search engines to crawl and understand. Update internal links to reflect any changes in URL structure or site hierarchy. Implement breadcrumb navigation and use descriptive anchor text for internal links to improve user experience and search engine understanding.

XML sitemap and robots.txt file

Update your XML sitemap to include all new URLs and remove outdated ones. Then, submit the updated sitemap to Google Search Console and Bing Webmaster Tools. Also, update your robots.txt file to allow or disallow search engine crawling as needed.

Mobile-friendliness and page speed optimization

Optimize your new site for mobile devices and improve page load times to ensure a positive user experience and better search engine rankings. Implement responsive design, compress images, and use caching and minification techniques for faster loading.

Managing duplicate content

Identify and address duplicate content issues by implementing canonical tags, noindex tags, or consolidating similar content.

Schema markup implementation

Implement schema markup on your new site to help search engines better understand your content and improve the display of your site in search results.

On-Page SEO Checklist

On-page SEO factors play a significant role in search engine rankings. Ensuring your new site’s optimized on-page elements will help maintain and even improve your current search engine performance.

Meta tags optimization

Optimize your new site’s meta tags, including title tags and meta descriptions, to accurately reflect the content of each page and incorporate relevant keywords.

Header tags and keyword usage

Use header tags (H1, H2, H3, etc.) to structure your content and incorporate relevant keywords. Ensure your content is well-written, informative, and contains a natural mix of target keywords and their variations.

Content quality and relevancy

Evaluate your existing content and update it to ensure it remains relevant, informative, and valuable to your target audience. Remove outdated content or consolidate similar pieces into comprehensive resources.

Image optimization and alt text

Optimize images by compressing file sizes, using descriptive file names, and adding alt text with relevant keywords to improve page load times and search engine understanding.

User experience and accessibility

Ensure your new site is easy to navigate and accessible to users with disabilities. Implement clear navigation, logical content organization, and descriptive text for buttons and links. In addition, ensure that your site complies with Web Content Accessibility Guidelines (WCAG).

Off-Page SEO Checklist

Off-page SEO factors, such as backlinks and social media presence, contribute to your website’s overall authority and search engine rankings. Therefore, addressing off-page SEO is essential during migration to maintain and improve your site’s performance.

Backlink audit and maintenance

  1. Conduct a backlink audit to identify your site’s most valuable backlinks and any potentially harmful ones.
  2. Reach out to the webmasters of sites linking to your old URLs, asking them to update the links to your new URLs.
  3. Monitor your backlink profile post-migration to ensure no valuable links are lost.

Updating social media profiles and local listings

Update your website’s URL on all social media profiles, local business listings, and online directories to ensure consistency and prevent confusion for users and search engines.

Notifying partners and influencers

Inform your partners, influencers, and other stakeholders about your website migration to minimize potential disruption and maintain relationships.

Testing and Quality Assurance

Before launching your migrated website, conduct thorough testing to identify and fix any issues impacting user experience or search engine performance.

Functional testing

  1. Cross-browser compatibility: Test your new site on different browsers and devices to ensure a consistent user experience.
  2. Broken link and redirect checks: Scan your new site for broken links and verify that all redirects work correctly.

SEO testing

  1. Metadata and on-page elements: Ensure all meta tags, header tags, and other details are correctly implemented and optimized.
  2. Sitemap and robots.txt validation: Verify that your XML sitemap and robots.txt file are correctly formatted and accessible to search engines.

Performance testing

Evaluate your new site’s page load times and overall performance to ensure optimal user experience and search engine rankings.

Monitoring and Maintenance

Once your migrated website is live, it’s crucial to monitor its performance and address any issues that may arise.

Post-migration performance analysis

Monitor your site’s organic traffic, keyword rankings, and user engagement metrics to identify potential issues or improvement areas.

Setting up and reviewing analytics and search console data

Ensure your new site is properly connected to Google Analytics, Google Search Console, and other relevant tools. Regularly review the data to identify trends and opportunities for optimization.

Ongoing SEO optimization and improvements

Optimize your website’s content, technical elements, and off-page factors to maintain and improve search engine performance.
