Pre-Migration:
Your Step-By-Step Checklist
The first phase of a successful migration strategy is the pre-migration. Use this opportunity to carry out a technical health check, collect data & do a content audit. This will give you a good understanding of what, on your existing site, is valuable & where there are issues that need fixing so your new site can outperform.

Pre-Migration SEO Checklist
- Verify Google Search Console access
- Complete Site Crawl – a full list of all internal pages & redirects on the current domain.
- Do a Site Crawl – use a tool that emulates how search engines crawl your site.
- Download Critical Data
- indexed pages
- non-indexed pages
- errors report
- most linked page
- Backlink & Broken Backlink profile
- Create your Migration Map
- Gather GA4 URLs
- Gather all URLs into 1 spreadsheet & de-dupe
- Add in the current redirects file
- Map your old URLs to new URLs
- Crawl & test your development site
Why These Steps Matter
Site Crawling Benefits
- Creates a site inventory
- Identifies valuable pages
- Uncovers technical issues
- Guides redirect planning
Why download indexed & non-indexed pages?
An indexed page is one that search engines have crawled & can show in search results; non-indexed pages aren’t crawled. Knowing both is crucial!
Collecting the URLs of both indexed & non-indexed pages gives you a complete inventory of all your content. This will help you with:
- Data preservation
- Redirect planning
- Improving content
Why download your errors report?
This report highlights existing technical problems, like 404 errors and server issues. Fix them before migration for a smooth transition & an improved technical SEO performance.
Why download your most linked pages?
Your most linked pages are your website’s VIPs – these are the pages other sites love to link to. Before you migrate your site, make sure these popular pages get special attention so you can keep that hard-earned search engine trust.
Why download your backlink & broken backlink profile?
Broken backlinks happen when a page is deleted or moved without a forwarding address & it can hurt your search rankings & customer experience.
By checking your backlinks profile you can create a redirects list. This way customers will automatically be sent to the right place on your new site.
Why download Google Analytics 4 URLs?
Your website move is another perfect time to do a content audit. Think of it as decluttering before moving house – why pack & move stuff you no longer need?
With your content audit you can identify the content to prune, improve, consolidate & keep.
Analytics Deep Dive
- Preserves SEO value
- Prioritises important content
- Fixes existing problems
- Improves customer experience
Redirect Mapping
Redirects are essential for migration, any pages left behind on your old site will result in a damaging 404 error.
The ideal is to map your URLs 1-to-1. But if a page is no longer on your new site, redirect it to the most relevant alternative. Think: a discontinued polo neck jumper going to the “Tops” category.
Now, 1-to-1 mapping can be time-consuming, especially on bigger sites. And, as a heads up, a lot of redirects can slow down your site’s server. So, here’s the trick: use redirect rules this will group URLs that fit a pattern & match them to their correct destination.
