Use AI to summarize this article
Your developers built a great product on React. Then someone said, "Let's just build the marketing site in Next.js too, since the team already knows it." It made sense at the time. Now your marketing team is filing Jira tickets to change a headline.
This is the Next.js marketing site trap. And it is costing B2B SaaS companies far more than they realise.
If your marketing team cannot update a CTA, launch a landing page, or publish a blog post without pulling an engineer off the product roadmap, you already know the problem. What you might not know yet is how straightforward a Next.js to Webflow migration can be when done right.
In this guide, we walk through why B2B companies end up here, what it costs them, and how to run a clean, SEO-safe migration from Next.js to Webflow that gives your marketing team full ownership of the site.

Why B2B Companies Built Their Marketing Sites on Next.js
It was a completely reasonable call in the early days.
Your engineering team was already deep in React. The CTO wanted consistency across the stack. Your first "website" was more of a product launch page than a real marketing site. Speed to ship mattered more than anything else.
Next.js gave the team full control: custom components, server-side rendering, fast load times when optimised well, and deep flexibility for anyone who could write code.
For a small founding team where an engineer would update the site occasionally, this worked fine.
The problem is that this setup does not scale with the marketing function.
What changes as the company grows:
As you move from seed to Series A to Series B, the marketing team grows. You hire a Head of Marketing, a content writer, a demand gen lead. They need to launch campaigns. They need to test landing pages. They need to publish case studies, update pricing, and iterate on the homepage based on positioning changes.
None of them can touch the Next.js site without an engineer.
This is not a Next.js problem exactly. It is a wrong tool for the job problem. Next.js is built for web applications. Your marketing site is a conversion tool. These are very different things.

The Real Cost of Running a Marketing Site on Next.js
Let's be honest about what this actually costs you.
Developer dependency for every single change
Every content update, whether it is a headline, a case study, a new pricing tier, or a button colour, requires a developer to write code, push to a branch, get it reviewed, and deploy. On a good day, this takes a few hours. On a busy sprint, it takes a week or more.
Your marketing team does not have a week. Campaign windows close. Competitor moves happen fast. Messaging needs to shift after a single sales call.
The opportunity cost here is enormous. Every hour an engineer spends updating the marketing site is an hour not spent on the product.
Headless CMS bolt-ons adding complexity and cost
Most Next.js marketing sites end up bolting on a headless CMS like Contentful, Sanity, or Strapi to give non-technical team members some editing ability. Now you are managing two systems, paying for two platforms, and still needing a developer every time you want to add a new field or change a layout.
This is a workaround, not a solution.
No visual editing for marketers
Marketing teams work visually. They think in layouts, sections, and page flow. When you are editing a Contentful field and hoping the frontend renders it correctly, you are not really in control of the website. You are filling in forms and trusting that a developer's template does the rest.
Webflow's visual editor is built for exactly this. What you see is what gets published.
Slow time to market for campaigns
A landing page that should take a day to build takes a sprint cycle. By the time the page is live, the campaign window has passed or the messaging has already shifted. This is one of the most common frustrations we hear from marketing leaders who come to us from Next.js setups.
Maintenance burden on engineering
Next.js sites require ongoing care: dependency updates, security patches, Node.js version upgrades, and Vercel or Netlify configuration changes. None of this is exciting work. All of it pulls engineering focus from the product.
At Flowtrix, we see this constantly with Series A and Series B companies. The engineering team built the site, got pulled back to the product, and now the site is running on an outdated version of Next.js that nobody wants to touch.
Next.js vs Webflow for B2B Marketing Websites
This comparison is specifically about marketing websites, not web applications. Next.js is a strong choice for building complex product interfaces and apps. But for a marketing site, the calculus is very different.

The headline difference is control. Webflow gives your marketing team full ownership of the site. Next.js does not.
This is not about which technology is better in a technical sense. It is about which platform is right for the job your marketing site needs to do.

When to Migrate to Webflow, and When to Keep Next.js
We will be honest here. Not every Next.js site should be migrated.
Strong signals that a Webflow migration makes sense:
- Your marketing team submits Jira tickets to change page content
- You bolted on Contentful, Sanity, or Strapi and it is adding cost and complexity
- Engineering spends 10 or more hours per week on marketing site updates
- You cannot launch a landing page without a sprint cycle
- Your site is running on outdated Next.js dependencies nobody wants to update
- You have hired marketing team members who cannot touch the site
When to keep Next.js:
- Your marketing site has custom user authentication baked in
- Pages pull real-time data directly from your product API
- You have interactive tools like ROI calculators that require backend logic
- Your frontend team is actively and regularly iterating on the site as a product
- Your marketing and engineering functions are deeply intertwined by design
For the vast majority of B2B SaaS marketing sites, including homepage, product pages, pricing, case studies, blog, and contact, Webflow is the stronger platform. These are content-driven, conversion-focused pages. They do not need a React framework.
Step-by-Step: How to Run a Next.js to Webflow Migration
A clean Webflow migration takes planning. Here is how we approach it at Flowtrix, based on 120+ global projects.
Step 1: Audit and discovery
Before touching anything, we audit the existing site. We document every page, every CMS field, every third-party integration, and every URL. We also audit current SEO performance: which pages are ranking, which have backlinks, and what the crawl structure looks like.
This takes a week but prevents problems that would take weeks to fix later.
Step 2: Content and component inventory
We list every page type and every reusable component on the site. For Next.js sites, this means mapping React components to their Webflow equivalents. We also flag any functionality that does not exist natively in Webflow so we can plan custom code solutions early.
Step 3: URL mapping and redirect planning
This is one of the most critical steps for SEO preservation. Every URL on the old site gets mapped to its new equivalent. We build the full redirect file before a single line of Webflow code is written.
Missing this step is the most common reason migrations hurt SEO.
Step 4: Design rebuild in Webflow
We build the site in Webflow from the design up. If a full redesign is in scope, this is where the new UX is built. If it is a like-for-like migration, we rebuild components faithfully while improving performance and Webflow CMS compatibility.
We use a component-driven approach so the marketing team can build new pages independently after launch.
Step 5: CMS architecture setup
For blogs, case studies, resource libraries, and testimonials, we set up Webflow CMS collections. Content editors can add a new case study in minutes. No developer required.
We also migrate existing content from any headless CMS like Contentful or Sanity.
Step 6: Integration migration
HubSpot forms, Google Analytics, Intercom, LinkedIn Insight Tag, and your consent tool all need reconnecting and testing. We use a QA checklist to verify every integration fires correctly before launch.
Step 7: SEO preservation
Meta titles, descriptions, canonical tags, schema markup, robots.txt, and sitemap all need transferring and verifying. We cover this in detail in the next section.
Step 8: QA and launch
We run a full QA pass across every page, form, redirect, and integration. Then we do a staged launch with DNS cutover monitoring.
Step 9: Post-launch monitoring
We monitor rankings, crawl errors, and Core Web Vitals for the first 30 days after launch. If anything drops, we catch it fast.

How to Preserve SEO During a Next.js Migration
SEO preservation is the number one concern we hear from marketing leaders before a CMS migration. It should be. A poorly executed migration can wipe out years of ranking progress.
Here is what a proper SEO-safe migration looks like.
301 redirects for every changed URL
If a URL changes at all during the migration, it needs a 301 redirect pointing to the new URL. No exceptions. Even URLs that seem unimportant may have backlinks or PageRank flowing through them.
We build the redirect map in advance and load it into Webflow's redirect manager or a custom code solution for larger redirect sets.
Meta tag transfer
Every page needs its meta title and description transferred. Not copied and pasted lazily. Reviewed and, where needed, improved.
Schema markup
Schema markup is often missing or broken on Next.js sites because it requires custom development work to implement correctly. Webflow makes it easier to implement and maintain. We set up structured data for organisation, service, FAQ, and breadcrumb schemas as part of every migration.

JavaScript rendering and indexability
One underappreciated benefit of migrating from a Next.js site to Webflow is that many Next.js pages are client-side rendered and may not have been consistently indexed by Google. Webflow pages are server-rendered HTML, which Google can crawl and index efficiently and reliably.
This means a migration done well can actively improve your SEO baseline, not just maintain it.
Sitemap submission
After launch, submit the new Webflow sitemap to Google Search Console. Monitor the index coverage report closely for the first two weeks. Resolve any crawl errors before they compound.
Common Mistakes to Avoid in a Next.js to Webflow Migration
We have seen every variation of this migration go wrong. Here are the mistakes we see most often.
Skipping the pre-migration SEO audit. If you do not know which pages are ranking and why before you start, you cannot protect them during the migration. Always audit first.
Moving too fast on URL structure changes. Changing URL slugs during a migration without a complete redirect map is a guaranteed way to lose rankings. Plan every redirect before you launch.
Not testing integrations before launch. HubSpot forms, analytics scripts, and tracking pixels need to be verified on the new site in a staging environment. Never test integrations live.
Leaving the headless CMS running after migration. Some teams migrate to Webflow but keep Contentful or Sanity running for the blog. Now you have two CMS platforms, double the cost, and twice the confusion. Consolidate fully.
Not training the marketing team on Webflow after launch. The entire point of this migration is to give your marketing team ownership of the site. If they are not trained on Webflow's editor, the site will still be developer-dependent.
Migrating without a design review. A Next.js to Webflow migration is the perfect time to clean up outdated design, improve page structure, and fix conversion issues. Teams that do a like-for-like migration without any design input often end up with the same conversion problems on a new platform.
How to Choose the Right Webflow Agency for a Next.js Migration
A Webflow agency that only does template builds is not the right fit for a Next.js migration. This is a technical project with SEO, design, and CMS complexity involved. You need a partner who has done this before.
What to look for:
- Certified Webflow Enterprise Partner status, not just a Webflow Certified Expert
- Demonstrated experience migrating JavaScript framework sites, not just WordPress or HubSpot
- B2B SaaS specialisation. They need to understand your buyer journey, content types, and conversion goals
- Clear understanding of the difference between a marketing site and a web application
- SEO preservation methodology, not just "we do SEO"
- Post-launch training so your marketing team can actually own the site
- CRO and conversion strategy built into the migration, not just a development-only scope
Ask to see examples of Next.js migrations they have completed. Ask specifically how they handle SEO preservation. Ask what happens to your team's Webflow training after launch.
