Your WordPress site is showing its age. Load times keep climbing. Core Web Vitals are in the red. Organic traffic has flatlined or started slipping. Plugin updates break the layout. The design still looks like 2018. You know something has to change, but you are afraid of losing the Google positions you fought hard to win. Go To Agency is based in France and works remotely with clients across Europe and North America. We rebuild your site on Next.js, the JAMstack framework behind Netflix, TikTok and Notion. Our methodology rests on three pillars: full SEO preservation through an exhaustive 301 redirect plan, native performance thanks to static site generation and incremental static regeneration, and a design refresh built for 2026 standards. We guide growing companies through this critical transition, entirely in writing. No traffic loss. No service interruption. A site ten times faster. A rethought user experience. And a technical foundation that will hold up for the next five years.

OUR PROCESS

Our process

A proven methodology, documented at every step

01
Step 01

Full audit (tech, SEO, UX)

We analyse your current site from every angle. A Screaming Frog crawl maps the URLs. An Ahrefs audit identifies the pages that generate traffic and the backlinks worth protecting. Core Web Vitals are measured through PageSpeed Insights. UX analysis pinpoints the friction. This diagnosis becomes the foundation of the entire migration strategy.

02
Step 02

Migration and redirect plan

We build the complete mapping from old URLs to new ones. Every page carrying SEO traffic is identified and preserved. The 301 redirect plan is documented line by line. Together, in writing, we confirm which content to keep, merge or retire. That document becomes the technical contract for the redesign.

03
Step 03

Modern design in Figma

Our design team builds the mockups in Figma, starting from your existing identity and current 2026 standards. Wireframes first, then high fidelity screens. A coherent design system with reusable components. Three responsive versions signed off: desktop, tablet and mobile. You approve every screen before development begins.

04
Step 04

Next.js development

We build your new site with Next.js 15, using the App Router and TypeScript. JAMstack architecture with static site generation for stable pages and incremental static regeneration for dynamic content. schema.org built in natively. Automatic image optimisation. Code versioned on GitHub with continuous deployment to Vercel.

05
Step 05

Migration and parallel testing

The new site is deployed to a staging environment. We migrate all your content, images and media. The 301 redirects are configured and tested. You review every page. Load testing, accessibility checks, technical SEO. Your current site stays online throughout this phase. No interruption.

06
Step 06

Cutover and post launch monitoring

A scheduled DNS switch with zero downtime. The 301 redirects go live at the same moment. The new sitemap is submitted to Google Search Console. Daily monitoring for 30 days: 404 errors, ranking fluctuations, Core Web Vitals. Continuous adjustments until organic traffic is fully stable.

ÉTUDE DE CAS : Abadie Magnan

Law firm redesign: WordPress to Next.js without losing a single ranking

[01] The challenge

Abadie Magnan was running a 2019 WordPress site that was slow, with a mobile PageSpeed score of 38 and an LCP of 4.2 seconds. Organic traffic on local queries had been flat for 18 months. Plugin updates regularly broke the layout. The admin interface had become unusable. The firm was worried about losing the Google positions it had won on highly competitive legal queries in its regional market.

[02] Notre solution

Complete rebuild on Next.js 15 with the App Router, hosted on Vercel. Exhaustive Screaming Frog audit. A 301 redirect plan covering 87 URLs. Modern Figma design compliant with legal advertising rules. schema.org LegalService and LocalBusiness markup. Full migration of the legal content library. Core Web Vitals optimisation through static site generation. Daily Google Search Console monitoring for 45 days after launch.

[03] The result

Mobile PageSpeed score up from 38 to 97. LCP cut from 4.2 to 0.9 seconds. Zero SEO ranking loss confirmed at day 30. Organic traffic up 34 percent at day 90 thanks to the performance gains. Contact conversion rate up 58 percent.

FAQ

Frequently asked questions

The cost of a redesign depends on the size of the site, the level of customisation and the scale of the SEO migration. A 10 to 15 page WordPress brochure site, a multilingual site and a large content catalogue represent completely different workloads. Every quote covers the full audit, design, development, content migration, 301 redirects, SEO testing and 30 days of post launch monitoring. Vercel hosting is included for the first year. We work on a quote only basis and send a tailored proposal in writing within 48 hours of the free audit.

Allow 2 to 4 weeks for a standard WordPress brochure site migrated to Next.js. One week for the audit and migration plan. One week for the Figma design. One to two weeks for development and content migration. A few days for testing and cutover. Larger projects (50+ pages, business system integrations) take 6 to 10 weeks. You receive a precise written schedule as soon as the quote is signed.

No, provided the methodology is rigorous. We build an exhaustive 301 redirect plan that maps every old URL to its new counterpart. Meta tags, schema.org markup and the semantic structure are all preserved. We monitor Google Search Console daily for 30 days after the cutover. Across every redesign we have delivered, no client has lost organic traffic.

WordPress carries several structural limits in 2026: mediocre performance without heavy optimisation, frequent security vulnerabilities, dependency on unstable plugins and constant maintenance. Next.js offers a modern JAMstack architecture: static site generation, incremental static regeneration, native performance, security by default and unlimited scalability. Your Core Web Vitals move from red to green. Your site becomes a technical asset rather than a liability.

The gains are dramatic. On a typical WordPress build, LCP often exceeds 3 seconds and the mobile PageSpeed score stays below 50. After migrating to Next.js on Vercel, we consistently reach an LCP under 1.5 seconds, an INP under 200 ms and a CLS close to zero. Mobile PageSpeed scores go above 90 and desktop scores approach 100. Your visitors feel the difference immediately.

We extract all of your content through the WordPress REST API or a structured export. Copy, images, videos, PDFs, documents: everything is recovered. Images are automatically converted to WebP and AVIF to cut file weight. Heavy videos are offloaded to dedicated CDNs. The editorial structure is respected. You get exactly the same content, better organised and far faster to load.

Yes, absolutely. Your domain name stays identical, and that is essential for preserving your SEO. We only change the DNS configuration to point at Vercel servers. The operation takes a few minutes and is completely transparent to your visitors. Your web address does not change, your printed materials stay valid and your advertising campaigns keep running.

We host your new site on Vercel, the official Next.js platform. Vercel provides a global edge network with more than 100 points of presence, automatic SSL certificates, native DDoS protection and 99.99 percent uptime. The first year of hosting is included in our redesigns. Beyond that, Vercel plans typically run from 0 to 20 euros per month depending on traffic, based on their published pricing at the time of writing. There is no comparison with classic shared hosting.

No. The new site is built in parallel on a private staging environment. Your current site stays online and fully functional for the whole project. The final cutover is a DNS configuration change that takes a few minutes. During DNS propagation (a few hours), visitors see either the old or the new site, never an error page. Effective downtime is zero.

We run a complete test suite: Core Web Vitals validation on 20+ pages, 301 redirect testing URL by URL, schema.org verification through the Rich Results Test, WCAG accessibility audit, responsive testing across 10+ screen sizes, cross browser validation on Chrome, Firefox, Safari and Edge, load testing, plus sitemap and robots.txt checks. You personally review every page on staging before the final cutover.

Post launch support runs for a minimum of 30 days. We check Google Search Console daily for 404 errors, coverage anomalies and ranking fluctuations. Missing redirects are added immediately. Core Web Vitals are verified every week. You have a direct email line to our team, with a written reply within 24 business hours. After that period, we offer monthly maintenance plans.

We commit in writing to three things. First, a full migration plan: URL mapping, 301 redirects, Search Console monitoring for the 30 days following the cutover, and free correction of any gaps we find. Second, work on Core Web Vitals across the main pages, measured before and after. Third, hosting chosen for its availability, with the host's SLA shared with you. Our agency puts its reputation on the line with every redesign we deliver.
