Every migration story starts the same way. Which is yours?

Mid-project

"We're in the middle of a redesign.
Someone just told us we need SEO migration support."

You're already deep into the project. The dev team is building, the content team is writing, and someone finally asked: "Wait, what happens to our organic traffic?" Late, but smart. Your GA4 tags, GTM, conversion pixels, and tracking codes are all set up on the old site. If nobody moves them, you'll go live and fly blind. And if you're running paid campaigns, any ad pointing to a URL that no longer exists can get your entire ad account suspended. But yes, we can still get ahead of all of it.

Proactive

"We're planning a migration.
We want to do it right the first time."

You have time to crawl the existing site, map every URL, and build a redirect plan before anything goes live. The thing most teams miss at this stage is backlinks. You've spent years earning links from G2, Capterra, guest posts, and directories. If those URLs change without proper redirects, all that authority starts leaking. We audit every backlink, flag what's in your control, and make sure nothing gets missed. Migrations done right don't just preserve traffic, they can outperform what you had before.

highest urgency
Post-disaster

"We migrated our site.
Traffic dropped and hasn't recovered."

You changed URLs, moved CMS platforms, or redesigned the whole site - and nobody handled the SEO side. Now Google's confused, links are throwing 404s, and your keyword rankings have effectively reset to zero. Google doesn't know those pages are "the same page" anymore, so you're starting the ranking process over from scratch. The good news: most of this is recoverable. The bad news: every week you wait makes it harder.

What we do

Before, during, & after launch:
We manage the SEO side of the entire move.

Before the new site goes live

We work directly with your dev team, not just the POC. We review redirect implementations, verify analytics tags fire correctly on staging, and check every active ad URL against the new structure so nothing sends paid traffic to a 404.


The earlier we're in, the more we can get ahead of, before any URL goes live.

Before the migration: anchor text, URL and link state mapping

While the migration is happening

We work directly with your dev team, not just the POC. We review redirect implementations, verify analytics tags fire correctly on staging, and check every active ad URL against the new structure so nothing sends paid traffic to a 404.


Every old link gets watched until it points somewhere we expect, with the right status code.

During the migration: old link to new link state monitoring

After the new site goes live

We re-crawl, run a full technical audit, and do the drop analysis: pre-migration vs. post-migration data from GSC and GA, page by page, keyword by keyword. From there, we build a recovery roadmap; exactly which pages need attention, which keywords to prioritize, and what changes will get your traffic back to baseline and beyond.


If something dropped, we know exactly which page, which query, and what to do next.

After the migration: pre-migration vs post-migration metrics

Want to talk through what this would look like for you?

We took an open-source SaaS through a
full migration. Here's what happened.

SuperTokens, a Y Combinator-backed authentication platform, came to us for SEO support that included a full website migration.

We never really had to worry about things going wrong during our migration. Spear Growth had a step-by-step plan. They clearly communicated where we were in the process and what we could expect. When it came to guidance, they never hesitated to go above and beyond, even on things that were outside the project's scope.

Within 2 weeks post-migration:


  • 88% of pre-migration daily impressions recovered
  • 90% of pre-migration daily clicks recovered
  • 80% of pages reindexed

Within 20 weeks:


  • Daily average traffic up 174%
  • Sign-ups increased 117%
  • Domain authority higher than pre-migration levels
  • Content pieces from our strategy ranking in top 5; one at #1

SEO migration support for every type of move.

Domain migration

The highest-risk scenario because domain authority effectively resets. We manage the redirect mapping and backlink recovery to minimize the damage window.

URL restructuring

Reorganizing your site architecture (adding category layers, changing slug formats, restructuring blog paths): every changed URL needs a redirect, every internal link needs updating, we map it all.

Content & design overhaul

Same URLs, new content and layout. Google needs to re-learn what each page is about. We make sure primary keywords, H1s, canonicals, and on-page SEO elements carry over correctly.

CMS migration

Moving from WordPress to Webflow, Webflow to WordPress, or any other platform switch. Same rules apply: URLs, redirects, analytics, DNS; everything needs to transfer cleanly.

Or any combination of the above. The more things change at once, the more there is to manage. That's exactly why you want an SEO team involved before the switch gets flipped.

Frequently Asked Questions

Do you actually build the new website?
Plus icon

No. We're the SEO team, not the dev team. Your developers build the site, your content team writes the copy, and we make sure that when it goes live, you don't lose what you built. We sit alongside both teams throughout the process; reviewing redirect implementations, verifying tracking, and making sure nothing critical falls through the cracks.

How long does the whole process take?
Plus icon

Typical migration projects run 2–3 months from first crawl to post-migration recovery roadmap. Smaller sites with clean structures can be faster. Larger sites (10,000+ pages) or migrations involving multiple types of changes simultaneously can take a full quarter. A lot of the variance comes down to design and stakeholder decisions that need to happen before launch.

When's the best time to migrate?
Plus icon

During your slowest business quarter. You will see a traffic dip, it's expected and unavoidable. The goal is to time it so that dip happens when the business impact is lowest. Don't migrate in your peak revenue quarter.

We've already migrated and traffic dropped. Can you still help?
Plus icon

Yes. Most of what gets broken in a bad migration is recoverable. We pull historical data from GSC and GA, run a full drop analysis to identify exactly what's bleeding, and build a recovery roadmap. The catch: we can't crawl your old site if it no longer exists, so the earlier you bring us in post-migration, the more we have to work with. Every week you wait makes recovery harder.

Does this work for any CMS or platform?
Plus icon

Yes. The SEO principles are the same whether you're moving from WordPress to Webflow, Webflow to a custom build, or staying on the same CMS but redesigning everything. Our work happens at the strategy and oversight layer, so the underlying tech stack doesn't change what we do.

Will we need to involve our dev team?
Plus icon

Yes, heavily. The redirects, tag implementations, and technical fixes all have to be executed by whoever owns your codebase. We work directly with them, not just your project manager, to make sure things are done correctly the first time. If you don't have a dev team, you'll need one (or an external dev agency) to implement what we recommend.
