SEO Audit before migration: Identify risks before taking the leap
Before migrating a website, an SEO assessment is essential to preserve and improve your rankings. This analysis involves three crucial actions.
Comprehensive SEO performance analysis
Evaluate your current SEO performance: Where does your traffic come from? Which keywords rank well? Which sites link to yours? This data helps identify what works and establishes a solid foundation for the migration.
Identifying existing SEO issues
Broken links, misconfigured redirects, and pages invisible to Google… Detect these problems to prevent them from reoccurring on the new site and ensure a smooth transition.
SEO improvement recommendations
Leverage the migration to optimize your SEO: define a flexible page and URL structure for future growth, enhance your content, strengthen internal linking, and improve technical performance.
A well-executed audit allows you to migrate with confidence and lay the groundwork for even stronger SEO.
SEO optimization for the new site: Set yourself up for success
Website migration is the perfect opportunity to strengthen your SEO. Each element of your new site and CMS should be designed to maximize efficiency. A well-structured HTML layout helps search engines better understand your site and improves page visibility.
To follow SEO best practices, make sure to :
- Structure and organize pages and URLs properly;
- Use a clear heading hierarchy (H1, H2, H3...);
- Write optimized meta descriptions ;
- Add ALT tags to images to improve accessibility and SEO ;
- Test the site using tools like Google Search Console.
Loading speed also plays a key role in optimizing your new site. Use modern image formats like WebP to ensure optimal performance. This format reduces image file sizes while maintaining high quality. You can also enable compression and automatic resizing to adapt images to different displays.
To improve site navigation for both visitors and Google, focus on internal linking. Adding strategic internal links and updating existing ones strengthens your site’s SEO by reinforcing connections between pages. Additionally, help search engines better understand your content by implementing structured data. These tags enable rich results (reviews, prices, FAQs, events...) to appear directly in Google’s search results.
URLs and 301 redirects: Preserve SEO and avoid critical errors
Every URL carries value for your SEO. During a migration, maintaining or properly redirecting these structures prevents traffic loss.
When migrating a website, URLs often change, leading to 404 errors, traffic drops, and negative SEO impacts. To prevent these issues, implementing 301 redirects is essential: they help users and Google find the new pages while retaining SEO history. Without redirects, visitors may land on broken pages and leave, while Google struggles to index your content. A 301 redirect ensures a seamless transition, preserving both user experience and site visibility.Whenever possible, URLs should remain unchanged, especially for main pages, to avoid disrupting indexation. Analyze the current URL structure to identify which ones can be retained. For those that must change, 301 redirects take over. They transfer the authority of old pages to new ones, maintain SEO rankings, and prevent 404 errors, particularly crucial for blog posts.
Proper URL management ensures a smooth migration while keeping your SEO intact.
Backlinks: Retain and enhance your SEO authority
Backlinks (incoming links) signal to Google that other sites recognize your content as relevant and high-quality. During a site migration, you must preserve these links to maintain your search rankings.
Start by identifying existing backlinks using tools like Google Search Console or SEMrush. Once identified, reach out to partner sites and request an update to the links pointing to outdated URLs. If updating isn’t possible, setting up 301 redirects is essential. These ensure visitors and search engines are automatically directed to the new pages, preserving the SEO benefits accumulated over time.
Notify Google about your new site and avoid penalties
Your new site is live! Now, you need to help Google recognize your updates to accelerate indexing and strengthen your SEO.
Update and submit your sitemap to Google
Your sitemap.xml lists the pages for Google to crawl and index. Updating and submitting it via Google Search Console speeds up indexing and optimizes your rankings.
Optimize your robots.txt file
The robots.txt file controls which pages Google should prioritize. Proper configuration highlights essential content while preventing unnecessary crawls. Adjusting these settings improves how Google understands your site and enhances its SEO performance.
Post-migration audit and monitoring: Keep SEO on track
The first few days after a site migration are crucial to ensure everything runs smoothly and make necessary adjustments.
- Closely monitor your site to prevent traffic loss.
- Detect and fix 404 errors to eliminate broken links.
- Analyze SEO performance changes using SEMrush, Google Analytics, and Google Search Console to assess migration impact.
- Adjust SEO strategies based on observed results to maintain optimal visibility.
For an effective post-migration audit, check the following:
- URL Structure: Ensure new URLs follow a logical format and that redirects are correctly set up.
- Meta Tags and Metadata: Verify that title tags, meta descriptions, and Hn headings are properly configured.
- Redirects: Test 301 redirects to prevent SEO loss and ensure smooth navigation.
- Technical Errors: Identify and fix any bugs, data loss, or SEO issues before and after launch.
Use SEO analysis tools like:
- Google Search Console to check page indexing, detect 404 errors, and identify technical issues.
- SEMrush to scan the site for errors, track keyword rankings, and compare SEO performance before and after migration.
