Technical SEO & Core Web Vitals Engineering
Crawlability, indexability, and speed are software architecture challenges. I eliminate render-blocking scripts, fix hydration errors, optimize Largest Contentful Paint (LCP), and engineer Schema.org JSON-LD microdata directly inside your codebase.
Surgical Technical SEO Deliverables
Every technical obstacle preventing search crawlers from rendering and indexing your site is resolved in code.
Core Web Vitals (LCP, INP, CLS) Refactoring
Eliminate render-blocking JavaScript and CSS, optimize font loading with next/font, convert media to WebP/AVIF formats, and guarantee 95+ Lighthouse performance scores.
- Sub-1.2s Largest Contentful Paint (LCP)
- Zero Cumulative Layout Shift (CLS < 0.05)
- Instant Interaction to Next Paint (INP < 150ms)
- Server-side critical CSS inline injection
Next.js SSR & Edge Rendering Architecture
Fix empty SPA shells that cause Googlebot indexing failures. We configure Server-Side Rendering (SSR) and Incremental Static Regeneration (ISR) for instant crawling.
- 100% crawlable pre-rendered semantic HTML
- Dynamic edge-caching via Cloudflare / Vercel Edge
- Automated incremental cache revalidation (ISR)
- Hydration error remediation and bundle tree-shaking
Semantic Schema.org JSON-LD Microdata
Hand-engineer complex, nested Schema.org knowledge graphs to qualify your pages for rich snippets, FAQ accordions, breadcrumbs, and knowledge panels.
- Service, FAQPage, Article, Organization schemas
- Strict Google Rich Results Test validation
- OpenGraph and Twitter Card automated tags
- Entity disambiguation for high AI Overview relevance
Crawl Budget & Indexation Governance
Direct search engine crawlers to your most profitable URLs while preventing crawl budget waste on duplicate parameters, pagination loops, or staging leaks.
- Strict self-referencing canonical URL hierarchy
- Automated multi-sitemap.xml with accurate lastmod timestamps
- Defensive robots.txt directive hierarchy
- Automated 301 redirect map and 404 defect resolution
Google Search Console Defect Remediation
Resolve cryptic GSC indexing errors like 'Crawled - currently not indexed', 'Discovered - currently not indexed', and 'Page with redirect' directly in code.
- Index coverage diagnostic & automated sitemap submission
- Crawl stat analysis and server response time tuning
- Mobile usability and viewport dimension fixes
- Search Console API integration for programmatic checks
Automated Lighthouse CI & Regression Prevention
Ensure new product deployments never break your Core Web Vitals or SEO tags by embedding automated Lighthouse CI checks into your GitHub Actions workflow.
- Automated Lighthouse PR gating (blocks score drops)
- Core Web Vitals real-user monitoring (CrUX) setup
- Schema syntax regression test suites
- Competitor SERP ranking and speed alert webhooks
The 4-Phase Technical SEO Sprint
Transparent, measurable milestones delivered directly through clean Git Pull Requests.
Comprehensive Codebase & Server Audit
We clone the codebase and analyze bundle sizes, server latency (TTFB), rendering pipelines, GSC crawl logs, and third-party script bloat.
Surgical Performance Refactoring
Direct source-code modifications: asset optimization, script deferral, dynamic code-splitting, font display tuning, and server-side cache headers.
Schema & Indexation Architecture
Injecting semantic JSON-LD schemas, dynamic XML sitemaps, canonical tags, and resolving all Google Search Console indexing defects.
Verification, CI/CD Gating & Handoff
Re-crawling with Screaming Frog, running Google Rich Results validation, deploying Lighthouse CI guards, and tracking Google Search Console re-indexing.
Every Sprint Backed by Verified Lighthouse Scores
You receive before-and-after audit logs, PageSpeed field test records, and Search Console re-indexation logs.
Frequently Asked Questions — Technical SEO
Why should a software engineer handle technical SEO instead of a digital marketer?
Technical SEO happens in your source code, server headers, and deployment pipeline. Marketers can tell you that your Largest Contentful Paint is slow or that you have JavaScript rendering issues, but they cannot refactor your Next.js components, code-split client bundles, fix hydration mismatches, or configure edge-caching rules. A Solution Architect implements the exact code solutions that permanently fix these issues.
How do you guarantee a 95+ Google PageSpeed / Lighthouse score?
We address the fundamental engineering bottlenecks: preloading critical assets, converting heavy images into WebP/AVIF, eliminating render-blocking CSS/JS, utilizing system or optimized web fonts with zero layout shifts, and deploying intelligent CDN caching. We test across both Mobile and Desktop profiles.
Can technical SEO fix 'Discovered - currently not indexed' in Google Search Console?
Yes. 'Discovered - currently not indexed' almost always means Googlebot found your URLs but decided not to crawl them because of slow server response times, low internal link equity, or perceived content duplication. By optimizing server latency, establishing clear canonical tags, and improving internal linking architecture, Google rapidly queues and indexes these pages.
Do you also handle regional Kerala technical SEO audits?
Yes! In addition to global tech stacks, I operate a dedicated regional practice for businesses in Kerala, Kochi, and Trivandrum. You can learn more on my dedicated Kerala Technical SEO page.
Will you need full access to our code repository?
Yes, for direct implementation sprints. I typically work via a dedicated Git branch (e.g., feature/technical-seo) and submit clean Pull Requests with before-and-after Lighthouse logs for your engineering team to review and merge.
