Search Engine Optimisation

Migrating your website doesn’t have to be risky. With Website Success, we handle every aspect of your migration if you’re an SEO client — planning, technical optimisation, redirects, content management, and post-launch monitoring.

If you’re not using our SEO services, careful planning and attention to the points in this blog post can help you avoid common pitfalls.

Key Takeaways:

  • Plan every step: URL mapping, backups, and coordination.
  • Manage technical SEO: redirects, speed, mobile optimisation.
  • Monitor post-launch: traffic, rankings, and errors.

Migrating your website can be exciting!

It’s a chance to improve design, functionality, and user experience. But without careful planning, it can also pose serious risks to your SEO. Broken links, lost traffic, and ranking drops are common if SEO isn’t prioritised.

At Website Success, we make sure your migration is smooth and stress-free. If you have SEO services with us, we handle every step, from planning to post-launch monitoring, so your rankings, traffic, and search visibility are protected.

1. Pre-Migration Planning

What we do for SEO clients:

  • Audit your current site: Identify high-performing pages and keyword rankings to preserve.
  • Set clear migration goals: Whether improving page speed, redesigning, or restructuring content, every step is planned.
  • Create a full URL map: Ensure every page is mapped to the new structure to maintain traffic and rankings.
  • Backup your website: Complete backup before making changes.
  • Coordinate our team: Developers, designers, and stakeholders are aligned to prevent mistakes.

If you’re handling it yourself:

  • Make a list of your top pages and URLs.
  • Know your SEO goals and what you want to improve.
  • Back up your entire site before starting any changes.
