React with the SEO and performance defaults handled
Next.js development for sites and applications that need both interactivity and strong SEO performance.
Next.js is a React framework that adds server-side rendering, static generation, routing, and API routes on top of React, so a site gets both React interactivity and the SEO and load-time performance of a traditionally rendered page.
What is Next.js Development?
Next.js is a React framework that adds server-side rendering, static generation, routing, and API routes on top of React, so a site gets both real interactivity and the SEO and load-time performance of a traditionally rendered page.
Skipping this layer usually means shipping a pure client-side React app - content only renders after JavaScript loads in the browser, which leaves crawlers and impatient visitors both looking at a blank page for longer than they should, and organic visibility suffers as a result.
It's different from a plain client-side React build, which trades that SEO and load-time cost for simplicity, and from a static-only site generator, which can't easily support a logged-in application layer alongside a public marketing site the way Next.js does.
Common problems we solve
Blank page for crawlers
A pure client-side React app renders after JavaScript loads, so crawlers and slow connections often see an empty shell.
Weak Core Web Vitals
Unoptimised images and render-blocking JavaScript drag load times down, and rankings with them.
One rendering strategy for every page
Every route forced into the same SSR or static choice, regardless of what that page actually needs.
Marketing and app on separate stacks
A public site and a logged-in application built and maintained as two disconnected codebases.
SEO handled inconsistently
Metadata and structured data added page by page with no consistent system behind them.
No dedicated data-fetching layer
Server-side data access and auth handled inconsistently across pages instead of through a proper API layer.
Everything covered in this service
Rendering Strategy
SSR, SSG, or incremental regeneration - chosen per route based on what that page actually needs.
SEO-Optimised Architecture
Server-rendered content, metadata, and structured data handled as a build requirement, not an afterthought.
API Routes
Backend-for-frontend endpoints for server-side data fetching, auth, and middleware.
Image & Asset Optimisation
Automatic image resizing, formats, and lazy loading built into the framework.
Deployment & Hosting
Vercel or self-hosted deployment configuration, with the build pipeline set up and documented.
Our optimization framework
Plan Rendering
Not every page needs the same rendering strategy - we decide SSR versus SSG versus static per route, not as a blanket choice.
Build
Pages, components, and API routes get built against that plan.
Verify SEO
Structured data, metadata, and server-rendered content get verified for the pages that need to be discoverable.
Review Performance
Core Web Vitals and image optimisation get checked before launch, not left to be discovered in production.
Configure Deployment
Build pipeline and hosting - Vercel or self-hosted - get set up and documented.
What actually changes
| Before | After |
|---|---|
| Blank shell in the initial HTML response | Meaningful content present in the initial server response |
| One rendering strategy applied to every page | SSR, SSG, or ISR chosen per route |
| Images served at full size and manually optimised | Images automatically resized, formatted, and lazy-loaded |
| Data fetching scattered across client components | API routes handling server-side data access and auth |
| Deployment configured ad hoc per environment | Documented build pipeline and hosting configuration |
What we report on
Core Web Vitals
Tracked before and after launch against the same benchmarks crawlers and users judge the page on.
Crawlability
Verified through server-rendered content and structured data checks, not assumed.
Page load performance
Measured on the routes that carry the most traffic, not a single homepage test.
Build and deploy reliability
Tracked through the documented pipeline so releases stay predictable.
Tools & platforms
Industries we optimize for
Built for teams like yours
Why choose EASI7
We fix tracking before we touch results
Every engagement starts with the same audit we'd run on our own accounts, so the numbers you're optimizing against are actually true.
One accountable team, not siloed vendors
The same team that does this also owns the rest of your stack - no handoff, no blame-shifting between vendors.
Built for how AI search actually works
Everything we build is structured to be extractable by AI answer engines, not just ranked in a list of blue links.
Reporting tied to your own dashboard
Every number we report ties back to GA4/GTM events you can see directly - not a screenshot from a tool you can't independently verify.
We treat SEO and Core Web Vitals as build requirements, checked before launch, not items to revisit after a ranking drop.

How to engage us for this
Project-based
A defined outcome with a start and end date - an audit, a migration, a campaign build, a tracking overhaul. Fixed scope, fixed price, agreed upfront.
Ongoing retainer
Continuous management and optimization once the initial build is live - campaigns, SEO, reporting, and iteration run every month under one accountable team.
Advisory
Strategy and oversight without full delivery - we review what's already running, unblock decisions, and point an in-house or existing team in the right direction.
Common questions
It's React with rendering, routing, and API handling built in, which removes the need to assemble those pieces separately. The tradeoff is a more opinionated framework - which is usually a net gain, not a cost.
No. Pages that don't change often are usually better served with static generation, which is faster and cheaper to run. SSR is for pages where the content genuinely needs to be current on every request.
Yes, and it's a common request when the underlying issue is SEO or initial load performance on a client-side-only React build. The scope depends on how tightly the current app's routing and data fetching are coupled to its existing setup.
It removes several of the common causes - unoptimised images, render-blocking JavaScript, slow initial content - but Core Web Vitals also depend on third-party scripts, hosting, and page-specific content, which a framework alone can't fix.
No - rankings depend on far more than rendering strategy, including content quality, backlinks, and competition, none of which Next.js touches directly. What it does reliably fix is the technical barrier of content not being visible to crawlers, which is a real and common problem on client-side-only React sites.
No. Vercel is built by the Next.js team and is the easiest path, but Next.js apps can be self-hosted or deployed on most major cloud providers - the right choice depends on your existing infrastructure.

Next.js Development, in detail
Scope, area by area
| Area | What we deliver |
|---|---|
| Rendering setup | SSR, SSG, or a mix, chosen per route based on what that page actually needs |
| SEO foundation | Metadata, structured data, and server-rendered content where crawlers need it |
| API layer | API routes for backend-for-frontend logic and server-side data access |
| Performance tuning | Image optimisation and Core Web Vitals review before launch |
How this compares
| Next.js | Client-Side-Only React |
|---|---|
| Content available in the initial server response | Content renders after JavaScript loads in the browser |
| Stronger default SEO characteristics | Requires extra work to be crawler-friendly |
| Built-in routing and API routes | Requires a separate router and backend setup |
