Next.js for business websites in Romania: the complete guide
A complete guide to Next.js for business websites in Romania: performance, SEO and AI search, cost, maintenance, migration and how to choose a partner. When it is the right choice and when it is not.
In short: Next.js is an excellent choice for business websites where speed, SEO and AI-search presence matter for sales — but not for everything. This guide covers everything you need before you decide: performance, SEO/AEO, cost, maintenance, migrating off old stacks, and how to choose a partner that actually delivers.
What Next.js is and why it matters for business
Next.js is a framework on top of React that renders pages on the server (or at build), not just in the browser. The practical difference for a business: the site delivers ready-rendered HTML, fast and indexable, instead of letting the browser build everything from JavaScript. For a customer searching on mobile, that means a site that loads instantly — and a site that loads instantly converts better.
It's not "trendy for the sake of it". It's a technical choice with direct business consequences: good Core Web Vitals (a Google ranking factor since 2021), full control over technical SEO, low long-term maintenance cost.
When Next.js is the right choice
- A business site where speed and conversion matter — presentation, lead generation, premium e-commerce.
- Custom platforms and web apps with unique flows that plugins can't solve.
- Headless e-commerce that needs premium UX and performance.
- Migrating off an old stack (legacy PHP, heavy WordPress) that has become a drag.
- When you want full technical control over SEO/AEO and AI-search readiness from the start.
When it is NOT the right choice
Let's be honest — Next.js isn't the universal answer:
- A blog edited daily by a non-technical team — often better on WordPress, where anyone adds a page without code.
- Very small starting budget and a simple site — a WordPress template costs less upfront.
- A niche feature that already exists as a mature plugin — don't rewrite what exists.
I detailed the comparison in Next.js vs WordPress for business websites — including the scenarios where WordPress wins.
Performance and Core Web Vitals
This is the strongest argument for Next.js. A business site loses customers before they see the offer if it loads slowly. Core Web Vitals — LCP, INP, CLS — are both a ranking factor and a conversion factor.
Next.js starts with an advantage: pre-rendered HTML, minimal JavaScript, optimized images. But the advantage isn't automatic — it must be built correctly. The most common performance killer isn't the code, it's the images. I wrote a complete image optimization checklist and two concrete case studies: from 74 to 97 on mobile and LCP from 56 seconds to under 2. Plus a 75 to 99 Lighthouse guide with the classic measurement pitfalls.
The rule: measure on real mobile, don't guess. A business site should have LCP under 2.5s and CLS under 0.1 on real users.
SEO and AI search (AEO)
SEO is no longer just about classic Google. More and more people search through ChatGPT, Perplexity and AI Overviews — and get the answer without clicking. If your brand isn't in that answer, you don't exist for that user.
Next.js gives you full technical control over both:
- Classic SEO: canonical, hreflang, sitemap, Core Web Vitals — directly in code, not limited by plugins.
- AI search (AEO): clean structured data, citable FAQs, and
llms.txt. I explained exactly what llms.txt is and how to write one, and how to implement structured data correctly in Next.js App Router without the duplicates that break rich results.
A modern business site should be built AEO-ready from the start — far cheaper than bolting it on later.
Why Next.js over the alternatives
I argued at length why Next.js and Node.js for modern websites. In short: real performance, SEO and AI search under control, reduced maintenance cost through fewer components that break, and a development experience that allows fast iteration.
It doesn't mean the alternatives are bad. It means that for a clear segment — business sites where performance and presentation matter — Next.js delivers more than its extra complexity costs.
Migrating off an old stack
Many businesses have a functional but outdated site — on Yii, CakePHP, or a WordPress overloaded with plugins. The question isn't "is the stack bad", it's "is it holding me back?".
When the answer is yes, a Next.js rebuild can turn a slow site into one on par with the brand. See the case study from Yii to Next.js for the premium Kulttur showroom — LCP 1.9s and CLS 0 on real users, catalog restructured around search intent, bilingual with native hreflang.
The key: don't migrate 1:1 (you copy the limitations too), rebuild the information the way the real customer searches.
Cost and maintenance
The upfront cost of a Next.js site is often higher than a WordPress template. But the total 3-year cost (TCO) tells a different story: cheap hosting (often free on the base tier), zero plugin licenses, far fewer points of failure, less security maintenance.
Rule of thumb: the longer you keep the site and the more important it is to the business, the more Next.js wins financially. And maintenance doesn't disappear — an abandoned site degrades. A maintenance subscription with Core Web Vitals monitoring keeps the site fast and secure long-term.
How to choose a partner
A good Next.js site depends on who builds it. Not every agency that says "we do Next.js" actually delivers. I wrote a separate guide on how to choose a Next.js agency in Romania: test the portfolio in PageSpeed, ask for transparent pricing, confirm you talk directly to the developer, check the SEO on their own site.
How to start
- Clarify the need: what type of site (presentation, shop, platform), who edits the content, how important it is to revenue.
- Choose the right stack: bare Next.js, Next.js + headless CMS, or WordPress if that's the answer.
- Build performant and AEO-ready from the start: optimized images, structured data, llms.txt.
- Plan maintenance: who keeps the site after launch.
