Website Migration Checklist: Avoid Traffic Loss

Website Migrations Are High Risk

A botched migration can lose 30-50% of organic traffic overnight. Careful planning prevents this.

Pre-Migration

Crawl and Benchmark

- Crawl entire current site and save results - Record current rankings for target keywords - Document current organic traffic by page - Save current sitemap and robots.txt - Note all redirects currently in place

URL Mapping

- Map every old URL to its new equivalent - 301 redirect old URLs to new ones - Test redirects in staging environment - No URL should return 404 that previously returned 200

Content Audit

- Verify all content transfers correctly - Check that metadata transfers (titles, descriptions) - Confirm structured data is in place - Test internal links point to new URLs

During Migration

- Deploy during low-traffic hours - Monitor 404 errors in real-time - Test critical user journeys immediately - Verify redirects are working - Check analytics tracking is firing

Post-Migration

Week 1

- Monitor traffic daily, compare to pre-migration - Check Google Search Console for errors - Submit updated sitemap - Monitor redirect chains (no double redirects)

Month 1

- Track ranking changes for key terms - Fix any crawl errors reported by Google - Update backlinks where possible - Compare conversion rates to baseline

Maintaining and Securing Your Site

Website security requires ongoing attention, not one-time setup. Implement HTTPS everywhere, set proper Content Security Policy headers, and keep all dependencies updated to patch known vulnerabilities. Schedule monthly security scans and establish an incident response plan before you need one. Regular backups with tested restore procedures protect against both technical failures and security breaches. A comprehensive maintenance schedule covering updates, performance monitoring, and security auditing prevents the gradual degradation that turns a well-built website into a liability.

Web Accessibility Essentials Strategies

Every market and audience is different, so treat these website migration checklist strategies as hypotheses to test rather than rules to follow. Run experiments, pay attention to what your data tells you, and double down on what actually moves the needle for your business.
