Moving an online shop to a new platform is one of the riskiest projects in ecommerce. If URLs change without a redirect plan, search rankings, traffic and revenue can disappear overnight. This checklist is designed for Coulsdon retailers, manufacturers and brands that want to replatform safely without losing visibility.
Pre-migration audit
Start by exporting a full list of existing product and category URLs, titles, meta descriptions and traffic data. Identify your top-performing pages and priority keywords. These are the pages you must protect first. A Coulsdon ecommerce website with a strong local following can lose loyal customers if product pages start returning 404s, so the audit is critical.
URL mapping and redirects
Create a spreadsheet that maps every old URL to its new equivalent. Where the URL changes, set up a 301 redirect. Where the product or category no longer exists, redirect to the closest relevant page, not the homepage. Test redirects before launch using a staging environment and crawl the site with a tool such as Screaming Frog.
Content and metadata
Keep the same title tags, meta descriptions, headings and on-page copy where possible. Search engines use these signals to understand relevance. If you improve them as part of the migration, do so carefully. Sudden wholesale rewrites can cause ranking fluctuations. Migrate first, optimise second once traffic has stabilised.
Pre-launch testing
Before going live, test the checkout, product filters, search, mobile layout and page speed. Submit the new XML sitemap to Google Search Console and monitor 404s, impressions and rankings daily for the first two weeks. The sooner you catch problems, the faster you can fix them. We include this level of care in our Growth package for Coulsdon ecommerce website projects.
Frequently asked questions
Will a migration affect my rankings?
All migrations carry some risk, but a planned approach with 301 redirects, URL mapping and testing keeps disruption to a minimum. Most sites recover within a few weeks.
How long before traffic recovers after a migration?
Traffic usually stabilises within 2 to 6 weeks, depending on the size of the site and how well the redirects are implemented.
Do I need a staging site?
Yes. A staging or test environment lets you check redirects, content and functionality before visitors and search engines see the new site.
What is a 301 redirect?
A 301 redirect tells browsers and search engines that a page has permanently moved to a new address. It passes most of the original ranking signals to the new URL.
