Technical SEO as an engineering discipline
Crawling, indexability, Core Web Vitals and architecture — the three layers that make a modern web system rank. We gather the most useful articles per layer here, plus the engineering reasoning behind them.
We read every page with the crawler's eyes first
Before we optimise UX, we verify indexability. A beautiful page Google can't parse is marketing theatre.
We measure performance against real users
Lighthouse is a diagnostic, not a proof. CrUX, RUM and server logs show what actually rendered.
Architecture decides SEO scalability
Route structure, internal linking and data models determine whether a topic cluster compounds — or cannibalises itself.
Make sure search engines can read your site
If Google can't crawl or index a page, nothing else matters. This layer covers crawl budgets, indexability rules, JavaScript rendering, sitemap discipline, and what different crawler types actually request.
Crawl Budget and How to Optimize It
Crawl budget describes the practical limit of how many URLs a search crawler can fetch from your site. On large sites, crawl budget is often the hidden constraint behind slow indexing and inconsistent visibility.
How Search Crawlers Work and What Types Exist
Search engines rely on automated crawlers to discover, analyze, and index web content. Understanding how these crawlers operate is foundational for modern SEO, especially in an era where traditional search and AI-driven systems increasingly overlap.
Indexation, Content Structure, and Semantics
Clear content structure significantly improves how crawlers interpret a page. Search engines rely on semantic HTML and structured data to understand hierarchy, context, and relative importance of information.
Site Architecture and Crawl Efficiency
Site architecture forms the foundation of how efficiently crawlers discover and interpret your content. A well-designed structure reduces crawl friction and helps search engines correctly assess page importance.
Site Types and What Crawlers Need From Each
SEO architecture is not one-size-fits-all. A blog, a SaaS site, an e-commerce shop, and a marketplace generate different URL patterns, update dynamics, and internal link graphs — which means crawlers behave differently.
Programmatic Pages Without Cannibalization: Internal Linking, Templates, and Search Intent Control
Programmatic SEO scales only when intent is separated and internal linking reinforces hierarchy. Without that, pages compete and rankings destabilize.
SSR vs CSR in Next.js: What Google Actually Indexes - and What It Doesn't
Google can execute JavaScript, but rendering is not equal. For SEO-critical pages, SSR remains the most reliable foundation.
Low Text-to-HTML Ratio in Semrush: Should You Fix It on Modern Next.js Websites?
The warning looks scary, but it is usually a byproduct of modern component-based HTML. What matters is intent, rendering, and content depth - not a ratio.
Performance is a ranking factor — and a UX one
LCP, INP, CLS, bundle size, build time, runtime cost. We treat performance as a system property — not a checklist of audit fixes — measured against real user data, not synthetic Lighthouse runs.
What Slows Next.js Builds in Real Projects (and How to Fix It Without Breaking SEO)
A technical breakdown of why large Next.js builds become slow, why full pre-rendering hurts team velocity, and how to keep SEO while cutting build times.
Is Vercel Burning Your Budget? How to Actually Reduce Costs in React & Next.js — Without Falling Into Optimization Fanaticism
Vercel costs often spike due to architectural decisions, not the platform. Learn how to reduce Next.js costs without breaking your architecture.
Consent Mode + GA4 in the EU: How to Measure Performance Without Breaking GDPR or SEO
Consent Mode is not just compliance. It shapes data quality, SEO decisions, and performance optimization in the EU.
Why Unused CSS Happens in Tailwind & Next.js - and How to Remove It Safely
Unused CSS is normal in modern Tailwind + Next.js projects. The goal is control, not elimination.
How We Run a Core Web Vitals Audit: From Lighthouse Scores to Real-User Data
A real CWV audit starts with users, not tools. We combine field data, lab analysis, and architecture review to prioritize impact.
JS/CSS Too Large: How Bundle Size Impacts Core Web Vitals - and SEO Indirectly
Semrush flags JS/CSS size as a performance signal. It is not a text issue, but it can hurt Core Web Vitals, UX, and SEO outcomes when left unchecked.
How information architecture shapes ranking
Programmatic pages, internal-link topology, route structure, semantic content models. The decisions you make at the framework level determine how easily a topic cluster can be built — and how cleanly it can grow.
How We Design System Architecture Before Writing Code
A practical architecture preparation process for production systems: domains, data ownership, API contracts, system boundaries, and infrastructure assumptions.
Monolith vs Microservices for Seed-Stage Products
A practical reference for choosing between modular monoliths and microservices in seed-stage products based on operational complexity, team structure, and system evolution.
Product Analytics Architecture for SaaS
A practical reference for product analytics architecture in SaaS: event tracking, schema design, ingestion, transformation, visualization, and privacy constraints.
