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.
Site Architecture for Efficient Crawling and Indexing
Connect hierarchy, internal links, sitemaps, canonicals and robots controls into a crawlable site architecture without unbounded URL traps.
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?
A low text-to-HTML ratio warning in Semrush looks alarming on React and Next.js sites, but it's almost never the real problem. Here's what the metric actually measures, why modern frameworks trigger it, and the rendering question that genuinely matters for SEO in 2026.
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.
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.
Site Architecture for Efficient Crawling and Indexing
Connect hierarchy, internal links, sitemaps, canonicals and robots controls into a crawlable site architecture without unbounded URL traps.
