Performance Architecture for Enterprise Next.js 15 Projects
Server components, layered caching and image discipline: the architectural recipe behind consistent…
Read articleEvery agency claims their sites are "SEO-friendly". Here is what that should actually mean — 12 controllable, measurable requirements.
Crawlability & indexability
1. Server-side rendering or static generation
Critical content must arrive in the HTML, not only after JavaScript runs.
2. A dynamic sitemap.xml
Hand-maintained sitemaps die of neglect. It should update itself as content changes, with real lastmod values.
3. Disciplined robots.txt & noindex
Admin panels, search results and thank-you pages should not be indexed — but one wrong rule can deindex your whole site. Few rules, correct ones.
4. Canonical URLs
If the same content answers on multiple URLs, declare one canonical address per page.
Speed: Core Web Vitals
5. LCP under 2.5s
Optimize hero images (AVIF/WebP), inline critical CSS, keep server response under 200ms.
6. CLS under 0.1
Set image dimensions, load fonts with font-display: swap, reserve embed space.
7. INP under 200ms
Split heavy JavaScript; keep the main thread free. More in our performance architecture article.
Meaning: structured data & metadata
8. JSON-LD structured data
Organization, BreadcrumbList, Article, FAQPage, Product — structured data unlocks rich results.
9. Unique titles & descriptions
Every page needs its own title (≤60 chars) and description (~155 chars). These drive click-through rate.
10. Open Graph & social cards
og:image, og:title and twitter:card decide how shared links look — the invisible traffic hero.
Structure
11. Semantic HTML & heading hierarchy
One H1 per page, a logical h2/h3 tree, meaningful link texts, alt attributes everywhere.
12. Internal linking strategy
Service page → case study → related article → contact: this mesh deepens both users and crawlers.
