A Website Migration That Keeps Your Traffic With You

A website migration can sound deceptively simple.

Move the old site.

Install the new one.

Change a few settings.

That is often where the trouble starts.

One URL disappears, a redirect gets missed, Google finds five hundred errors and a page that generated leads for four years suddenly does not exist.

A well-planned migration should make the move nearly invisible to visitors and easy for search engines to understand.

Different migrations move different things

“Migration” can describe several projects.

You may change hosting while keeping the website exactly the same.

You may move from a proprietary CMS to WordPress.

You may change domain names, merge sites or completely reorganize the information architecture during a redesign.

Those projects carry different levels of risk.

A simple hosting move may preserve every URL.

A new domain and full rebuild require much more planning.

Start with an inventory.

Pages, articles, products, media, forms, accounts, redirects, connected tools and important data all need to be understood.

SEO belongs on that list.

Some URLs may generate much more traffic, links and revenue than others.

Treat them accordingly.

Understand the house before moving the boxes.

A website migration needs an old-to-new URL map

When an address changes, you need to tell browsers and search engines where the content went.

That is what redirects do.

Imagine an old page at /services/web-design/ moving to /website-design/.

If the old URL simply disappears, existing links lead to an error.

A properly configured permanent redirect sends people to the new location and signals that the content has moved.

On a small website, this may involve a few dozen pages.

On an older store or large content platform, it can involve thousands.

Create a real mapping table.

Every important old address needs a logical destination.

Sending every missing URL to the homepage is usually a lazy solution.

Preserve URLs when there is no reason to change them.

The less useful stuff you break, the smoother the migration becomes.

Content that performs should not disappear by accident

Redesigns make people want to clean house.

That is healthy until someone deletes an old page solely because it looks dated.

Check performance first.

Organic traffic, inbound links, conversions, impressions and commercial relevance all help determine what should happen.

Older content can be improved.

Two weak pages may be merged into one stronger resource.

Some content genuinely deserves deletion.

Make that decision deliberately.

Search visibility earned over years is an asset.

Do not treat it like construction debris.

Internal links should be updated too.

If a URL changes, links inside your own website should eventually point directly to the new destination instead of relying on redirects forever.

Launch day deserves a checklist

A successful migration is prepared before launch.

Test the new site in a staging environment.

Verify forms.

Review important pages.

Prepare redirects.

Configure analytics and measurement.

Then the switch becomes controlled.

One especially important check is indexing.

Development environments are often intentionally blocked from search engines.

Leave that setting active after launch and your beautiful new website politely tells Google to stay away.

HTTPS, DNS, internal links and search-related files also deserve verification.

E-commerce increases the stakes because orders, accounts, stock and payments may all need to stay consistent during the move.

A good migration usually looks boring.

That is a compliment.

The work continues after launch

The new site is live.

Everything looks fine.

Keep watching.

The following days can reveal missing pages, redirect problems, indexing issues and unexpected behavior.

SEO and analytics tools provide useful signals.

Some movement can happen after a major migration.

A large, persistent drop deserves investigation.

Check business actions too.

A form that worked in staging may fail in production.

Tracking may have been missed.

An old campaign link may still point to a retired URL.

The migration is finished when the new site works properly in real life and has inherited the value the old one earned.

Frequently asked questions

How much does a website migration cost?

The budget depends heavily on site size, CMS, number of URLs and data that needs to move. Brand Architect web projects generally start around €1,500, while ongoing support can start from €100 per month with hosting and maintenance included. Complex migrations require an audit before quoting.

Can a website migration hurt SEO?

Yes. Visibility can drop when important URLs disappear, redirects are missed or search engines cannot properly crawl the new site. A well-planned migration protects existing SEO signals and minimizes avoidable disruption.

Can I change domain names without losing all my traffic?

Yes, although the change needs careful planning. Old URLs should redirect to their new equivalents, connected tools need updating and performance should be monitored after launch. The more history the old domain has, the more carefully the move should be handled.
