PROBLEMS WE SOLVE

Why is your site still slow after all that optimization?

You've done the optimization work. But the pages are still slow. These problems probably look familiar.

01

Optimized everything, still slow

Images compressed. Bundles split. Lazy-loading everywhere. The rendering layer underneath, the foundation, hasn't been touched.

02

Caching that breaks itself

Stale when it should be fresh. Fresh when it should be cached. Your CDN, ISR, and data layers work against each other.

03

Fast frontend, slow experience

Your frontend is clean. But APIs take five seconds to respond. Your rendering strategy exposes every one of them.

04

Pages that don't rank

Client-side rendering delays indexing. For sites with thousands of pages, Google prefers server-rendered content. Your pages exist. They just don't rank.

OUR SOLUTION

From endless tweaks to lasting change

From chasing symptoms to fixing root cause. From optimization cycles that repeat to architectural change that lasts. Guessing becomes knowing.

What's actually slowing you down

We diagnose with field data, define the right rendering strategy for each page type, and implement caching that works together. No guesswork. No wasted optimization cycles.

How we approach it

We start with field data, not lab scores. Map your rendering strategy page by page. Fix what's broken.

WHAT YOU GET

Real outcomes delivered

icon wrench

Foundation fixed

Surface optimizations finally work because the layer underneath is right. You stop repeating the same fixes every quarter.

Consistent speed, every region

Same fast experience whether users are in New York or Singapore. Regional performance gaps stop hurting rankings.
icon shield check

Backend shielded

Caching absorbs traffic spikes so your slow APIs don't become slow pages. Users never see your backend latency.

Pages that rank

Server-rendered content that crawlers see immediately. No more indexing delays from client-side rendering.

Confidence to release

Deploy during peak traffic without holding your breath. Your caching and rendering architecture holds.

Cache that works together

CDN, ISR, and data layers aligned. Your caching works the way you expect.
OUR APPROACH

How we fix the architectural foundation that makes every other optimization work

The problem changes from project to project. The process doesn't. Expand each step to see what it looks like in practice.

01. Rendering Audit

open tab

We map your current rendering approach page-by-page: PPR, SSR, SSG, ISR, CSR. We identify where it's costing you performance. Most enterprises have never audited this layer. The gaps compound over time.

02. Rendering Strategy

open tab

Right strategy for each page type. Static where possible, ISR for dynamic content that tolerates staleness, PPR for selectively fresh regions and SSR only where freshness can't wait. Enterprises often default to SSR everywhere. Server costs spike.

03. Cache Alignment

open tab

CDN, ISR, and data layer caches aligned to work together. One misconfigured cache header is often the difference between a 3-second page and a 300ms page.

04. Backend Shielding

open tab

Caching configured to absorb traffic spikes so your slow APIs don't become slow pages. 80% of your traffic should hit cache. When it doesn't, the 20% hitting your backend defines your conversion rate.

05. Field Data

open tab

We measure with real-user data, not Lighthouse. Lab scores look 30-50% better than what real users experience. That gap is where rankings and conversions decay.

06. Cache Invalidation

open tab

Tag-based and time-based invalidation so content stays fresh without sacrificing cache hit rates. Updates publish when they should. Cached content serves when it should.

FAQ on our Rendering & Caching Optimization services

How do I improve Core Web Vitals on a Next.js site?

Fix the rendering and caching foundation, not the symptoms. We diagnose with field data, then pick the right rendering strategy per route – SSR, ISR, or PPR – and align your cache layers so content is served fast and fresh. LCP and INP are usually rendering and JavaScript problems, so that's where we start.

Our Next.js app keeps failing Core Web Vitals – what now?

Repeated failures usually mean the rendering strategy or caching layer is wrong, not that you need another quick patch. We trace each failing metric to its cause with field data and fix it at the foundation – the same approach that took clients to 70% faster LCP.

Google flagged our Core Web Vitals as poor – how do we pass?

Passing CWV means fixing what real users experience. We measure field data – the data Google actually uses – find why LCP, INP, or CLS are failing, and fix the rendering, caching, and script issues behind them. Then we confirm the pass in the same field metrics.

My site has poor SEO because it's slow and renders client–side – how do I fix it?

Client-side rendering hurts both speed and crawlability – content that depends on JavaScript can be less reliably discovered by some crawlers, so we render critical content in the initial HTML – fast to load and easy to index. That fixes the speed and the SEO at once.

We're paying too much for hosting and infrastructure – how do we cut costs?

A large share of infra cost is wasted compute – re-rendering pages that could be cached and shipping payloads that could be smaller. We align your caching strategy (ISR, cache-control, CDN) so you serve more from cache and compute less.
