Technical SEO Specialist & Lead Engineer
Joshua Gutierrez
SEO strategist and full-stack engineer who builds the audit tooling, then does the work. Technical SEO, Core Web Vitals, and content systems for SaaS and B2B.
Joshua leads SEO at Axion Deep Digital and is the creator of DeepAudit AI, a proprietary SEO audit platform that renders pages the way Google does instead of parsing static HTML. He has run SEO end to end since 2014: technical fixes, on-page work, content built around real search intent, schema, and white-hat link building.
His edge is that he writes the code and the content. The same person who diagnoses a JavaScript rendering problem or a Core Web Vitals failure can ship the Next.js fix, the structured data, and the page that ranks. No hand-offs, no translation loss between the SEO plan and the implementation.
SEO Focus
Technical SEO
Core Web Vitals, render-path tuning, JavaScript SEO, crawl and indexation cleanups, canonicals, hreflang, sitemaps, robots hygiene, and redirect mapping for migrations that keep their traffic.
Structured Data & Schema
schema.org / JSON-LD implementation across Organization, Product, Article, FAQ, and Person types, plus Open Graph and Twitter Cards, so pages earn rich results and stay legible to AI search.
Content & Topical Authority
Keyword research aligned to search intent and funnel stage, topical clustering, SERP gap analysis, and content briefs written and edited in-house rather than outsourced.
Programmatic SEO
Template-based page generation and meta title and description generation at scale, with content pipelines that hold quality across large page counts.
Local SEO
Citation building and directory cleanup (Whitespark, BrightLocal, Moz Local), Google Business Profile, and the local signals that move map-pack visibility.
Analytics & Reporting
GA4, Google Search Console, PageSpeed Insights, Ahrefs, and Semrush, with monthly reporting that attributes movement to specific pages and campaigns.
Selected Outcomes
Built DeepAudit AI, a real-browser SEO audit platform
100+ checks across 15 categories on AWS Lambda with Puppeteer and Chromium. Cut audit preparation from several hours to under 15 minutes per site and surfaces rendering issues that source-only tools miss.
Authored a 292-site technical SEO study
Quantified the most common indexing, performance, and schema failures across small-business websites. 96.9% failed mobile Core Web Vitals; the dominant failure was loading latency, not layout shift.
Delivered 98+ Lighthouse scores across client builds
Through Core Web Vitals optimization, image pipelines, and render-path tuning, with technical SEO built into the foundation of every Next.js site at launch.
