Technical SEO Post-Migration: How to Find and Fix Hidden Errors
Website migration is a crucial process that, if not handled properly, can severely impact search engine rankings and organic traffic. Whether you are moving to a new domain, switching from HTTP to HTTPS, redesigning your site, or restructuring URLs, technical SEO issues often arise. Identifying and fixing these hidden errors is essential to maintain search engine visibility and user experience. In this guide, we will explore how to conduct a technical SEO audit post-migration, detect common issues, and implement effective solutions to optimise your website’s performance.
Understanding the Importance of Technical SEO Post-Migration
Technical SEO plays a vital role in ensuring that your website remains accessible to search engines and users after migration. Search engine crawlers rely on a structured site to index pages efficiently. If technical SEO problems persist after migration, search engine rankings may drop, resulting in lower traffic and reduced conversions. The migration process can affect page speed, sitemap structure, canonical tags, redirects, and overall search visibility. A thorough audit post-migration helps to identify hidden errors and prevent long-term SEO issues.
Conducting a Technical SEO Audit After the Migration
A technical SEO audit is a systematic analysis of a website to identify performance, indexing, and crawlability issues. Post-migration, it is essential to check the site’s structure, analyse search engine crawlers’ behaviour, and validate SEO elements such as meta tags and XML sitemaps. Google Search Console and other SEO tools can provide valuable insights into indexing issues, error pages, and crawl budget efficiency. Examining robots.txt files, SSL certificates, and hreflang tags will ensure proper indexing and a smooth user experience.
Checking for Indexing Issues and Search Visibility
One of the first steps in a post-migration audit is verifying whether search engines are indexing the new website correctly. Google Search Console provides reports on indexing errors, search rankings, and crawl status. If pages do not appear in search results, this may indicate issues with robots.txt files, meta tags, or canonical tags. Ensuring that important pages are indexed helps maintain search visibility and search engine rankings. If duplicate content issues arise, implementing canonical tags can help consolidate SEO efforts.
Fixing Redirect Issues and Maintaining Link Equity
Redirects are crucial to website migration. Improper redirections, such as loops or broken redirects, can lead to traffic loss and SEO performance issues. A 301 redirect ensures that search engines pass link equity from old URLs to new ones. However, multiple pages with unnecessary redirects may cause loading time delays, affecting the user experience. Conducting a redirect audit using SEO tools helps detect and fix misconfigured redirects, maintaining link structure and search rankings.
Optimising XML Sitemap and Robots.txt File
An updated XML sitemap is essential for search engines to understand the site’s new structure. After migration, submitting an accurate XML sitemap to Google Search Console ensures that search bots efficiently crawl and index web pages. Additionally, a misconfigured robots.txt file may unintentionally block search engines from crawling essential pages. Reviewing and updating robots.txt files prevents indexing errors and improves search engine optimisation. The sitemap should be regularly monitored to identify potential issues and enhance SEO efforts.
Addressing Duplicate Content and Canonicalisation Problems
Duplicate content can negatively impact search rankings and SEO performance. Post-migration, it is essential to check for duplicate content caused by URL variations or incorrect canonical tags. The preferred version of a web page should be specified using proper canonical tags to avoid dilution of search visibility. Websites with multiple pages containing similar content must implement structured canonicalisation strategies to consolidate authority and prevent SEO issues.
Enhancing Page Speed and Mobile Optimisation
Page speed and mobile optimisation are critical factors for search rankings. Post-migration, it is essential to test website performance using tools like Google PageSpeed Insights. If page speed is slow, optimising images, reducing file sizes, and enabling caching can improve loading time. With mobile devices accounting for a significant portion of web traffic, ensuring responsive design and fast-loading mobile pages enhances the user experience and search engine results.
Fixing Broken Links and 404 Errors
Migration often leads to broken links and error pages that harm SEO rankings. A thorough audit should identify 404 error pages and fix them by redirecting broken links to relevant pages. Googlebot and other search engine crawlers may struggle to index sites with excessively broken links, leading to poor search engine rankings. Using link-checking tools, businesses can repair internal and external links to maintain a seamless navigation experience.
Ensuring Secure Websites with SSL Certificates
A website migration to HTTPS requires the properly implementing of an SSL certificate. Search engines prioritise secure websites in search results, and an incorrectly configured SSL certificate can lead to SEO problems. Google Search Console alerts website owners to security issues, ensuring that the hypertext transfer protocol (HTTPS://) is correctly implemented. A certificate authority validates SSL certificates, helping maintain trust and search visibility.
Monitoring Search Console for Technical SEO Issues
Google Search Console is a valuable tool for identifying and resolving technical SEO problems. After migration, website owners must monitor search console reports for crawl errors, search performance, and indexing issues. Analysing search engine crawlers’ behaviour can reveal problems with site structure, meta descriptions, and search engine optimisation efforts. Regularly reviewing these reports helps maintain SEO rankings and search visibility.
Optimising Meta Descriptions and Alt Tags for SEO Performance
Meta descriptions and alt tags contribute to search engine rankings and user engagement. After migration, it is crucial to review and update meta descriptions to ensure relevance to the new site structure. Alt tags enhance accessibility and help search bots understand image content. Optimising meta tags and alt tags ensures that pages remain competitive in search engine results and improve search visibility.
