Migrating an international website is a complex process that requires careful planning and execution to preserve and enhance SEO performance. When executed properly, a site migration can improve site performance, user experience, and search visibility. However, even minor missteps—such as incorrect redirect structures, broken canonical tags, or inconsistent URL strategies—can lead to a significant drop in traffic and rankings.
Based on insights from real-world case studies, technical migration checklists, and international SEO best practices, this article outlines the key strategies and considerations for maintaining and improving SEO during the migration of international websites. The guidance is particularly relevant for U.S.-based businesses with global ambitions, as it addresses both technical and content-related aspects of the migration process.
Understanding the Challenges of International SEO Migration
International SEO involves optimizing a website to rank in multiple countries and languages. This process is distinct from local SEO, which focuses on a specific geographic location. For businesses operating in multiple regions, it is essential to structure the site in a way that clearly signals to search engines the relevance of content to specific audiences.
One of the primary challenges in international SEO migration is maintaining the correct URL structure. Google emphasizes the importance of a clear, intuitive URL strategy that reflects the regional and linguistic differences of the target audience. For example, using a country-specific domain (such as website.fr for France) is often recommended for its clarity and ranking benefits. However, this approach also comes with trade-offs, such as the need for separate analytics tracking and potential duplication of content across domains.
When migrating an international site, it is also crucial to ensure that canonical tags are correctly implemented. These tags help prevent duplicate content issues by indicating the preferred version of a page. In the context of international SEO, they are particularly important for handling multilingual content and regional variations.
Pre-Migration Preparation for International Websites
Before initiating the migration, a comprehensive pre-migration preparation phase is essential. This phase should include several key steps to ensure that the site remains visible and functional during and after the transition.
1. Document Existing URL Structure
One of the first steps in preparing for a migration is to thoroughly document the current URL structure. This includes mapping all existing URLs and their corresponding content. For international sites, this documentation should also include language and regional variations. This information is critical for developing a redirect strategy that preserves the integrity of existing links and ensures that users and search engines are directed to the correct new pages.
2. Set Clear SEO Objectives
Setting clear SEO objectives is a foundational step in the migration planning process. These objectives may include maintaining or improving search rankings, preserving traffic levels, or enhancing site performance metrics such as Core Web Vitals. For international websites, it is also important to consider language-specific goals, such as increasing engagement with a French or Spanish-speaking audience.
Clear objectives help guide decision-making during the migration and provide a benchmark for measuring success post-migration.
3. Coordinate with Stakeholders
Migration planning requires close coordination with stakeholders across different departments, including marketing, IT, and customer support. Each department may have different priorities and concerns related to the migration. For example, the marketing team may be focused on preserving branded search visibility, while the IT team may be concerned with technical implementation and server performance.
By aligning on goals and expectations early in the process, teams can work together to address potential challenges and ensure a smooth transition.
Technical SEO Considerations
Technical SEO forms the backbone of any successful migration. Even the best content strategy collapses without proper technical implementation. During the migration of an international site, technical considerations include redirect mapping, canonical tag management, and URL restructuring.
4. Redirect Mapping
Redirect mapping is a critical component of any migration. It involves creating a detailed list of all existing URLs and mapping them to their corresponding new URLs. For international sites, this process must account for language and regional variations.
The source materials emphasize the importance of maintaining a comprehensive spreadsheet that includes the original URL, the target URL, the redirect type, and the canonical URL (if different from the target). Redirects should be tested thoroughly before going live to ensure that they function as expected.
Redirect failures can lead to broken links, which negatively impact user experience and search rankings. Therefore, it is important to verify that all redirects are correctly implemented and functioning.
5. Canonical Tag Implementation
For international sites, canonical tags play a vital role in managing duplicate content. These tags indicate the preferred version of a page and help prevent search engines from indexing multiple versions of the same content.
When migrating a site, it is important to ensure that canonical tags are correctly updated to reflect the new URL structure. This includes handling cross-domain canonicals, where the canonical tag points to a version of the page on a different domain. For international sites, it may also be necessary to configure mobile canonicals to ensure that the correct version of the page is indexed.
6. URL Restructuring
URL restructuring is another key technical consideration. For international sites, the URL structure should be designed to clearly indicate the language and regional relevance of each page. This can be achieved through subdomains (e.g., fr.website.com), subdirectories (e.g., website.com/fr), or country-specific domains (e.g., website.fr).
Each of these approaches has its own advantages and disadvantages. Country-specific domains, for example, are often recommended for their clarity and ranking benefits. However, they also require separate analytics tracking and can be more difficult to manage at scale.
When restructuring URLs, it is important to ensure that the new structure is intuitive for both users and search engines. This helps improve navigation, reduce bounce rates, and enhance the overall user experience.
On-Page SEO Considerations
On-page SEO is another important aspect of international SEO migration. This includes optimizing page elements such as headings, meta descriptions, and schema markup to improve visibility in search results.
7. Heading Structure Optimization
Headings play a key role in structuring content and improving readability. For international sites, it is important to ensure that heading structures are consistent across all language and regional variations. This helps search engines understand the content and relevance of each page.
The source materials recommend using optimized heading structures that reflect the main topics and subtopics of each page. This not only improves user experience but also enhances search visibility by making it easier for search engines to index and rank the content.
8. Schema Markup Implementation
Schema markup is a powerful tool for enhancing the appearance of search results. It allows webmasters to provide additional context about the content of a page, such as the type of product, event, or article being displayed.
For international sites, it is important to ensure that schema markup is correctly implemented for each language and regional variation. This includes using the appropriate language tags and ensuring that the schema is consistent with the content of the page.
Schema markup can also be used to enhance local SEO by providing additional information about the business, such as its address, phone number, and business hours. This is particularly important for businesses with physical locations in multiple countries.
Post-Migration Monitoring and Optimization
After the migration is complete, it is important to monitor the site closely to ensure that everything is functioning as expected. This includes monitoring rankings, traffic, and technical errors to identify and address any issues that may arise.
9. Monitor Rankings and Traffic
One of the key post-migration tasks is to monitor rankings and traffic using tools such as Google Search Console (GSC). This allows webmasters to track how the site is performing in search results and identify any changes in rankings or traffic.
The source materials recommend filtering the data by country, query, and page to get a more detailed view of performance. This helps identify any issues that may be affecting specific regions or keywords.
It is also important to compare the data with pre-migration benchmarks to assess the impact of the migration. This provides a clearer picture of how the site is performing and whether any further optimization is needed.
10. Monitor and Fix Errors
Even the best sites can experience errors after a migration. These can include broken links, crawl errors, and technical issues that affect site performance. It is important to monitor the site regularly and address any issues as soon as they are identified.
This can be done using a combination of tools, including site crawlers, error logs, and performance monitoring tools. By addressing issues quickly, webmasters can minimize the impact on user experience and search rankings.
11. Resubmit Pages and Sitemaps
After the migration, it is important to resubmit pages and sitemaps to search engines to ensure that the new content is indexed. This can be done through Google Search Console and other similar tools.
The source materials recommend resubmitting individual pages if necessary, as well as the entire sitemap. This helps ensure that search engines are aware of the new content and can index it as quickly as possible.
