Best Website Migration Agencies (2026): 8 That Protect SEO

Key takeaways

• A migration is judged on one thing: whether your rankings, traffic and leads survive the move. The new design matters once that's true.

• Five checks separate a safe migration from a risky one: a URL inventory, a redirect map you sign off, metadata and schema carried over, analytics and CRM rewired, and a defined monitoring window.

• Only two agencies here publish the length of their monitoring: Broworks (30 to 90 days) and Goodspeed (30 days).

• Pick by destination: Webflow (Flow Ninja, Broworks, Finsweet), Framer (Goodspeed, Design Monks), SEO cover while someone else builds (SeoProfy), large eCommerce (OuterBox), traditional CMS (Marcel Digital).

• Marketing-site migrations start at about $5,000 to $10,000. Large CMS and eCommerce moves run well into five figures.

What is a website migration?

A website migration is any change to a site's platform, URLs, structure or domain that search engines have to learn again. Moving from WordPress to Framer counts, and so does merging two domains. Done badly, it can wipe out years of rankings in weeks. Done well, traffic holds and your team gets a faster site it can update itself.

The most common versions we see are moves off Storyblok, Wix, Webflow, Squarespace, Bubble and WordPress, plus sites stitched together from years of freelance handoffs.

Why do website migrations lose rankings?

Rankings drop when URLs change without one-to-one redirects, when titles, meta descriptions and schema don't come across, when internal links still point at the old site, and when nobody watches Search Console after launch. Almost all of it can be avoided. It just tends to be found too late, after traffic has already gone.

The line I keep coming back to: migrations rarely fail on launch day. They fail quietly in week three. Launch day looks fine. Then the redirects nobody tested start returning 404s, Google re-crawls, and the graph slides while everyone is busy with the next thing. Somebody should still be looking.

What separates a safe website migration from a risky one?

Five checks. A full URL inventory weighted by traffic, a redirect map you sign off before anything moves, metadata and schema carried across, analytics and CRM rewired and tested, and a monitoring window measured in days with a named owner. If an agency can't show you all five on a past project, you're taking the risk.

1. A URL inventory, with traffic attached. Every page, and which ones actually earn visits and backlinks. You can't protect what you haven't counted.

2. A redirect map you sign off. Every old URL with traffic or backlinks points one to one at its new home. If you never see the map, you're trusting a spreadsheet you've never read.

3. Metadata, schema and internal links carried across. Titles, meta descriptions, headings, alt text and structured data come over intact.

4. Analytics, tag manager, CRM and forms rewired and tested. The quietest disaster is a site that ranks fine but sends no leads to HubSpot for a fortnight.

5. A monitoring window, in days, with a named owner. Rankings, crawl errors and redirect health, checked after go-live by someone whose job it is.

And one rule of thumb: a fixed price without an audit is a guess. We've never quoted a migration blind, and I'd be wary of anyone who does.

Moving this quarter?

Send me your URL. We'll audit it and show you the redirect map before you commit, and the audit fee comes off the build.

How does Goodspeed run a migration?

In four steps: design system first, then the CMS and SEO, then the pages one by one, then an SEO and AEO pass followed by 30 days of watching rankings, crawl errors and redirects. The order matters. Your existing content and metadata are safe in the new site before anyone starts redesigning a single page.

1. Design system first. Components, text styles and three breakpoints, so every page we move lands on the same foundation. Most sites we audit carry six or more breakpoints, which means six places to edit every time anything changes.

2. CMS and SEO next. Existing meta descriptions and all of your content come into Framer before we design anything new. Then we reshape the collections around the people who'll update them every week, and train your team before handover.

3. Page by page. Each page is rebuilt, staged, checked against the signed-off redirect map and only then made live. Think of refitting a restaurant kitchen: you don't close for a month. You do it one station at a time between services, and you check every plate that goes out.

4. SEO and AEO pass, then 30 days of watching. Proper headings, lists and section tags keep you findable on Google and readable by ChatGPT and Claude. After go-live we monitor rankings, crawl errors and redirect health for 30 days.

In football terms: score the goals first, then do the skills. Get the rankings and redirects safe. The redesign flourishes come once the traffic is protected.

Sometimes the audit says the move isn't worth it yet. When that happens we say so, and you keep the URL inventory and the redirect plan either way.

One migration, and what it let the team do next

Zen Educate (legacy site to Framer). A Series B edtech running across the UK and US, whose site was slow to update and was blocking growth experiments. Zero downtime and SEO protection were written into the brief.

• Migrated page by page with zero downtime, zero SEO regression and zero launch delays

• CMS remodelled into four content hubs, with UK and US variants

• Google Tag Manager, Zoho CRM, Trustpilot, Heap and Hotjar kept working through the move

• The marketing team now runs 10x more growth experiments without engineering

"Goodspeed were a brilliant partner throughout the migration. They were fast, responsive, and incredibly easy to work with." Group Product Manager, Zen Educate

Zen Educate did not move for a nicer platform. It moved so marketing could run the site without waiting on anyone, and it kept its rankings while doing it.

Not sure what your current site is quietly earning? The audit starts with a URL inventory weighted by traffic, so you see which pages carry your business before you decide anything.

How did we choose these agencies?

We searched "best website migration agencies" and "website migration companies" in the US and shortlisted agencies that sell migration as a named service. Every agency, Goodspeed included, went through the same four tests, using only what each agency publishes and its Clutch profile, checked on 2 October 2026.

1. Published SEO process: a URL inventory, a redirect map and metadata and schema carried across, described on their own site.

2. Post-launch monitoring: whether they monitor after go-live, and whether they state for how long.

3. Transparency: a published price or minimum project size, and named clients.

4. Independent reviews: a Clutch rating with a review count you can check. Where a rating comes only from the agency's own site, the table says so.

Disclosure: Goodspeed is on this list and I run it. We held ourselves to the same four tests, and each entry, ours included, says where that agency is the wrong pick.

Website migration agencies compared

The 8 best website migration agencies

1. Goodspeed: best for moving to Framer and running the site yourself afterwards

What it is: an audit-first migration service for funded teams moving to Framer. We're a Framer Enterprise partner, with a 5.0 rating from 46 reviews on Clutch.

How it works: we audit before we quote. You sign off the redirect map before anything moves. We migrate page by page with zero downtime, then watch rankings, crawl errors and redirects for 30 days.

Pricing: from $10,000, and most migrations take about five weeks including the audit. The audit fee comes off the build. After the 30 days, you can move onto our Embedded Team from $2,000 a month, rolling monthly with no minimum term.

Proof: Zen Educate (zero downtime, zero SEO regression, 10x more growth experiments).

Best suited to: a marketing lead at a funded company who wants to keep the rankings and stop filing tickets for every change.

Where we're the wrong pick: we only migrate to Framer. If you've chosen Webflow, look at Flow Ninja or Broworks. If you run a large eCommerce catalogue, OuterBox is built for that scale.

2. Flow Ninja: best for large moves to Webflow with ongoing support

What it is: a Webflow agency since 2015, claiming 100+ migrations from WordPress, Squarespace, Wix, Drupal and Framer.

SEO process: full URL export, slug map, metadata and canonical transfer, bulk 301s, sitemap resubmission and Search Console monitoring after launch.

Pricing: Clutch lists a $10,000+ minimum and $50 to $99 an hour.

Proof: 21Shares, Trustly and Upwork.

Best suited to: teams moving to Webflow who want a long-term web partner.

The trade-off: ongoing monitoring runs through a retainer, so budget for it beyond the project.

3. Broworks: best for a fast, fixed Webflow migration sprint

What it is: a Webflow agency selling a three-week (15 business day) migration sprint.

SEO process: content audit, full 301 map, schema mapping and 30 to 90 days of post-launch monitoring, including AI-search visibility.

Pricing: "mid four-figure to high five-figure", according to its site.

Proof: Visa Franchise and Epiq Solutions.

Best suited to: B2B teams on WordPress or HubSpot CMS moving to Webflow quickly.

The trade-off: Webflow only. Complex CMS builds run six to eight weeks or more.

4. Finsweet: best for complex Webflow builds

What it is: the team behind Webflow's Client-First framework and Attributes, migrating WordPress and headless sites to Webflow.

SEO process: redirects, metadata carry-over and post-launch monitoring.

Pricing: not published.

Best suited to: migrations with heavy custom functionality inside Webflow.

The trade-off: Webflow only, and we couldn't verify pricing or the length of the monitoring window.

5. Design Monks: best for a WordPress to Framer move on a budget

What it is: a UI/UX agency with a WordPress to Framer migration service delivered in 30 days.

SEO process: 301 redirects and broken-link testing.

Pricing: Clutch lists a $5,000+ minimum.

Best suited to: cost-conscious teams wanting a redesign and a migration in one.

The trade-off: a design agency first, with migration as one of its services, and no stated post-launch monitoring.

6. SeoProfy: best when someone else is building the new site

What it is: an SEO agency that runs the search side of any migration without building the site: audit, staging checks, pre-launch crawl comparison, fixes and production monitoring.

Pricing: custom.

Proof: Preply and Jooble.

Best suited to: teams that have already chosen a build partner and want an independent SEO check on top.

The trade-off: you're managing two suppliers, and every handoff between them is a place for a redirect to slip.

7. OuterBox: best for large eCommerce replatforms

What it is: a large US agency that treats migration as a revenue-risk event.

SEO process: crawls at launch, 24 hours and 7 days, plus a 90-day roadmap.

Pricing: custom.

Proof: a Wine Enthusiast replatform the agency reports grew organic revenue 60%.

Best suited to: big catalogue and eCommerce sites.

The trade-off: built for scale, so it's heavy for a 30-page marketing site.

8. Marcel Digital: best for traditional CMS migrations

What it is: a US agency migrating WordPress, Drupal, Joomla and Umbraco sites. It's an Umbraco Platinum Partner.

Pricing: custom.

Proof: Absolute Software and PerkSpot.

Best suited to: mid-market companies staying on a traditional CMS.

The trade-off: no Framer or Webflow specialism.

Which platform should you migrate to?

Pick the platform your marketing team will be happy editing every week, then pick the agency that specialises in it. The tool matters less than who runs the site afterwards. If one or two people in marketing will own it, choose a visual CMS like Framer or Webflow over a build that needs an engineer for every change.

If you're still deciding, we've written up each move:

• Framer vs Webflow: who can edit it, CMS limits and what a Webflow to Framer move involves

• Framer vs WordPress: maintenance, security and blogging at scale

• Framer vs Squarespace and Wix vs Framer: when a growing brand outgrows a site builder

• Migrating from Bubble to code: for the product itself, as opposed to the marketing site

Doing some of it in-house? Our Framer migration guides walk through each move step by step, including moving from Drupal to Framer step by step.

What should you ask a migration agency before you sign?

Six questions: will you audit before quoting, can I sign off the redirect map, how do metadata and schema come across, which integrations will you rewire and test, how many days will you monitor and who watches, and which client migrated with you and kept their traffic. Vague answers to the redirect map or monitoring questions tell you enough.

1. Will you audit the current site before quoting? A fixed price without an audit is a guess.

2. Can I see and sign off the redirect map? It should list every URL with traffic or backlinks.

3. How do metadata, schema and internal links come across? Ask to see how they checked it on a past project.

4. Which integrations will you rewire, and how will you test them? Analytics, tag manager, CRM and every form.

5. How long do you monitor after launch, and what happens if rankings drop? Get the number of days in writing, and the name of the person watching.

6. Who's a client that migrated with you and kept their traffic? Ask for the name, then ask that client.

How much does a website migration cost?

Goodspeed migrations start from $10,000, with a fixed price agreed before anything moves. That covers about five weeks including the audit, and the audit fee comes off the build. Across this list, specialist migrations for a marketing site start at about $5,000 to $10,000, and large CMS or eCommerce replatforms are usually quoted custom.

What $10,000 buys you at Goodspeed:

• an audit and a URL inventory weighted by traffic, so you know which pages carry the business;

• a redirect map you sign off before anything moves;

• your existing content and meta descriptions carried into Framer before any redesign starts;

• a page by page migration with zero downtime;

• an SEO and AEO pass on headings, lists and section tags;

• 30 days of watching rankings, crawl errors and redirect health after launch.

Bigger sites cost more, and the list below says why. But you'll know the number before you commit, because we've never quoted a migration blind. Every price we charge is public, and you should expect the same from whoever moves your site.

From the agencies on this list:

• $5,000+: Design Monks (WordPress to Framer, with redesign)

• $10,000+: Flow Ninja (Webflow) and Goodspeed (Framer, audit fee comes off the build)

• Mid four to high five figures: Broworks (Webflow sprint)

• Custom: SeoProfy, OuterBox, Marcel Digital and Finsweet

What moves the price: the number of pages and templates, how many CMS collections need remodelling, the integrations to rewire (CRM, analytics, careers, forms), extra locales or regional variants, and how much you redesign against how much you move as it is. You pay 50% on signature and 50% at launch, and you own everything.
