Engineer-grade technical SEO services on Next.js, headless WordPress, Shopify Hydrogen, and Astro — covering Core Web Vitals, crawlability, indexation, structured data, JS-render, hreflang, and safe platform migrations. Every fix shipped to staging, verified in GSC, and regression-monitored so rankings never break on deploy.
What is technical SEO?
Technical SEO is the engineering layer that controls how search engines crawl, render, and index your site. It covers crawlability, indexation, rendering, Core Web Vitals, structured data, and hreflang — the foundation that determines whether Google and AI search engines can actually see, parse, and trust your content. Our technical SEO services align every fix against Google’s official crawling and indexing guidance (developers.google.com/search/docs/crawling-indexing) and the Core Web Vitals thresholds published on web.dev/vitals. Content cannot rank what Google cannot crawl, render cheaply, or index correctly — everything in content strategy, link building, and AEO/GEO sits on top of this foundation.
Neogen Media is an engineering-first shop — we build production sites on Next.js, Astro, headless WordPress, and Shopify Hydrogen every week. That matters because technical SEO in 2026 is a codebase problem, not a checklist. We know exactly where render-blocking JavaScript hides in App Router, why Hydrogen shipping bloated hydration kills LCP on Indian 4G, and how to make a Sanity-backed site return fully-rendered HTML to Googlebot without breaking ISR.
What this unlocks for your team
Core Web Vitals discipline
LCP, INP, and CLS tracked on mobile at the 75th percentile — measured in real-user CrUX, not synthetic lab runs.
Full indexation
Every revenue page crawled, rendered, and indexed — zero soft-404s, zero render budget waste, zero orphan URLs.
Schema-rich SERP
FAQ, HowTo, Product, Article, Organization, and LocalBusiness JSON-LD valid in Rich Results Test — feeds AEO/GEO too.
Safe migrations
Platform moves rehearsed on staging, full 301 map diff tested, and monitored post-launch so regressions are caught early.
How does technical SEO execution actually work?
We run technical SEO as a four-stage engineering pipeline: audit, fix, validate, monitor. Every finding is tied to a business outcome (indexation, CWV, click-through, revenue), every fix ships through staging with a rollback plan, and regression monitoring is wired in so breakage is surfaced early — not after a quarter of lost rankings.
Crawl + render audit
Full-site crawl via Screaming Frog with JavaScript rendering enabled. We diff raw HTML vs rendered DOM, log every indexation blocker, and pipe 1M+ line server logs through Claude, GPT-4o, and Gemini to surface Googlebot waste.
CWV + performance budget
Real-user CrUX + Lighthouse + WebPageTest on Indian 4G profiles. We set a per-template performance budget (JS KB, image KB, LCP target) and wire it into CI so a bad PR can never ship.
Schema + semantic markup
JSON-LD for Organization, Product, Article, FAQ, HowTo, BreadcrumbList, LocalBusiness, Service, Person — validated in Google Rich Results Test in CI. Schema doubles as AEO/GEO fuel for ChatGPT, Perplexity, and Gemini.
Migration / canonical / hreflang
Platform moves, URL restructures, and international rollouts are rehearsed on staging. Full 301 map, canonical + hreflang test matrix, and GSC change-of-address done to the Google playbook — not guesswork.
Monitoring + regression
GSC API + CrUX + log-file alerts piped into our in-house AI reporting workflow. We catch indexation drops, CWV regressions, and schema errors within hours, not quarters — so a bad deploy never silently tanks your revenue.
Where teams deploy this
Next.js + headless-CMS fixes
App Router rendering strategy, ISR tuning, streaming + Suspense boundaries, and Sanity/Contentful fetch patterns that return indexable HTML to Googlebot.
Large e-commerce (>50K SKUs)
Faceted navigation, parameter handling, PLP/PDP canonicals, crawl budget reshaping, and XML sitemap partitioning for catalogs at Shopify Plus / Magento scale.
Platform migrations
Shopify ↔ Hydrogen, WordPress ↔ headless, Webflow ↔ Next.js — full 301 maps, rehearsed on staging, monitored post-launch.
JS-heavy SPAs
React/Vue/Angular apps that render blank HTML to Googlebot — we diagnose hydration, pre-render, and SSR/SSG strategy to unblock indexation.
International hreflang
Multi-region rollouts across en-IN, en-US, en-GB, ar-AE — bidirectional hreflang, x-default, canonical alignment, and sitemap structure that actually works.
Indexation bloat cleanup
Soft-404s, parameter noise, tag-page sprawl, and thin-content indexation trimmed to free crawl budget for pages that earn revenue.
Built on best-in-class tools
Technical SEO on the Neogen Engineering Stack
We treat technical SEO as a codebase discipline, not a PDF audit. Every finding ships through the same engineering stack we use to build client sites — staging, CI validation, and real-user monitoring — so fixes are durable and regressions are caught before they cost rankings.
- Headless-aware crawling with rendered DOM snapshots so JS-rendered content is audited, not guessed
- Real-user CWV monitoring surfaced through Neogen reporting agents — 75th percentile LCP/INP/CLS on Indian 4G
- Schema.org validation with Google Rich Results Test baked into CI on every PR
- Hreflang + canonical strategy designed with a test matrix before a single tag goes live
- AI-augmented log-file analysis (Claude, GPT-4o, Gemini) on >1M-line server logs to surface crawl waste
- Migration rehearsals on staging with 301 map diff tooling — zero-downtime moves, verified pre-launch
