What a Website Migration Needs to Protect Search Rankings

Get launch day wrong, and years of SEO work can go up in smoke. But plan in search visibility from the start, and it can all be avoided.

A migration is a chance to elevate the digital experience, adopt better technology and give a business room to grow. It’s also a major business event. Whether it’s a platform change, a site redesign, or consolidates several websites under one brand, your existing digital footprint is a priceless asset.

Website migration SEO helps protect that asset: the content, links and technical foundations that allow customers to find your business through search.

Here’s the A-Z of successful migration.

First - SEO audit

Job number 1 is understanding your existing site’s value. It’s gradually built up an audience: some pages attract significant organic traffic, others hold valuable backlinks, and some rank for keywords that bring in customers.

The audit needs to cover:

• Organic performance: which pages bring in traffic, enquiries and sales.
• Indexed pages: which pages search engines currently include in their index.
• Keyword rankings: the key search terms for your business.
• Backlinks: which pages other websites link to.

Google’s Search Console and Analytics, and Screaming Frog can help build this picture.

The audit establishes a baseline to measure the migration, and identifies pages that deserve particular attention during planning, testing and launch.

Every important URL needs mapping and redirecting

A critical migration error to avoid is changing URLs without accounting for the old ones. Before anything goes live, get your redirect map in place

A 301 redirect tells search engines that a page has moved permanently, sending visitors to its new address. It helps search engines associate the old page’s signals with its replacement and keeps existing links useful.

A sound redirect plan involves:

1. Listing existing URLs, including those found through crawls, analytics, sitemaps and backlink data.
2. Matching each changed URL to the most relevant equivalent on the new site, prioritising high-value pages.
3. Testing the redirect rules before launch, then checking the live URLs immediately afterwards.

Avoid redirecting everything to the homepage. Searches for particular products or services should reach the relevant page. Google also advises keeping redirects in place for as long as possible - a year, minimum.

Update internal links, paid advertising destinations and product feeds to use the new addresses directly.

Protect content and on-page SEO

Redirects keep traffic flowing to the right place, but those pages still need to earn their rankings. Redesigns can ditch useful copy, change headings or drop page titles. Which can weaken previously high-performing pages.

For your top pages, review and carry across the elements that support their performance:

• Page titles and meta descriptions.
• Headings and useful body copy.
• Internal links.
• Relevant images and descriptive alt text.

Improvements can still be made, but be intentional - where practical, separate chunky content changes from the migration so any performance shifts are easier to investigate.

Take care of the technical SEO

As stunning as your new site may be, it can still be difficult for search engines to access. Before launch, check your important pages can be crawled and indexed, then review:

• Robots.txt - allows access to the pages you want search engines to crawl.
• Canonical tags - identifies the correct preferred version of each page.
• XML sitemap - contains the new, indexable URLs.
• Internal links - point directly to the correct destinations without unnecessary redirects.
• Page speed and mobile usability - ensures the new experience performs well, including against your existing site.
• Structured data: ensures relevant markup has carried across and validates correctly.

Remove staging restrictions, such as password protection, noindex tags or restrictive robots.txt rules, from the public site at launch. Check the live website immediately to confirm that the intended pages are accessible.

Plan for the worst!

As the saying goes, better to have a plan and not need it, than to need a plan and not have it!

Well before launch, agree what happens if something misfires, who makes the call, and how the team will restore service.

Before launch, make sure:

• Redirects, forms, checkout, analytics and conversion events have been tested in a staging environment.
• It’s agreed which failures require an urgent fix or rollback, such as a broken checkout or inaccessible key pages.
• The old site and its data are backed up and available for an agreed period.
• Any recovery process accounts for orders or data created after launch.
• Launch decisions and critical checks have named owners.

A recovery plan gives the team clear actions to follow when time matters.

Pick your moment…

Avoid Black Friday, Christmas, or other busy trading periods. Who needs the extra drama?

Do it when those responsible for development, SEO, trading and analytics are around to test the live site and respond quickly. Launching early in the week gives the team time to monitor performance and address any issues during the site’s first few days.

Some ranking fluctuation is normal while Google recrawls and reindexes a changed site. That makes preparation and monitoring essential: the team needs to distinguish expected movement from problems that require action.

Monitor post-launch performance

Before you crack open the champagne, remember the site launch isn’t the finish line. Check critical customer journeys and available real-time data on the day, then monitor performance closely over the following weeks.

Your checks should cover:

• Organic traffic and conversions: vs the pre-migration baseline, allowing for seasonality and demand fluctuation.
• Customer journeys: including forms, basket activity and checkout completion.
• Rankings: particularly the priority keywords identified in the audit.
• Indexing and crawl errors: reviewed through Google Search Console.
• Redirects: including incorrect destinations, redirect chains and 404 errors.
• Paid campaigns: checking that ads and product feeds reach live, relevant pages and tracking works correctly.

Jump on any unexpected changes - it’ll reduce the potential impact on customers and revenue.
