Fix the Foundation That Blocks Your Rankings
Technical SEO audit and implementation for websites with crawlability, indexing, or performance issues. I fix robots.txt, canonicals, Core Web Vitals, schema markup, and JavaScript rendering problems — Philippines-based engineer, remote-friendly.
Good Content Is Ranking Below Its Potential Because of Fixable Technical Problems
A well-written page that loads in 7 seconds on mobile loses most of its users before they read a word — and Google measures that. Canonical tags pointing in the wrong direction split link equity between two versions of the same page. An XML sitemap with 404 URLs wastes crawl budget on dead ends. These are not edge cases — they are the norm on sites that have never had a technical audit.
Technical SEO is a checklist of concrete issues with concrete fixes. The problem is that most business owners and marketers don't know what's wrong — and most SEO audits deliver a 200-row spreadsheet without telling you which 10 items actually matter.
A Prioritized Technical Fix Plan — and the Implementation to Go With It
I use Screaming Frog, Google Search Console, and Lighthouse to run a structured technical audit, then prioritize findings by estimated ranking impact. You get a clear list of what to fix, in what order, with the reasoning behind each priority — plus direct implementation in your CMS or codebase for the items that need a developer.
- Crawl analysis identifying every indexation, redirect, and canonical issue
- Core Web Vitals diagnosis with LCP, CLS, and INP root cause analysis
- Schema markup audit and implementation for rich snippet eligibility
- XML sitemap and robots.txt corrections
- Search Console error resolution with before and after documentation
Technical SEO deliverables by area
Site Audit
Full crawl analysis covering indexation status, redirect chains, broken links, duplicate content, canonical conflicts, hreflang errors, and crawl efficiency. Prioritized by impact, not alphabetically.
Core Web Vitals
LCP, CLS, and INP root cause diagnosis from real field data (CrUX) and lab data (Lighthouse). Fixes implemented for images, font loading, layout shift sources, and interaction latency.
Schema Markup
JSON-LD structured data for FAQ, Article, Product, BreadcrumbList, LocalBusiness, and HowTo schemas. Tested in Google's Rich Results Test before and after deployment.
Crawlability
Robots.txt review, crawl budget analysis, internal link equity distribution, and Googlebot access verification. Ensures every important page is discoverable and no crawl budget is wasted on low-value URLs.
Site Architecture
URL structure review, silo architecture assessment, pagination handling, and breadcrumb implementation. A logical hierarchy helps both users and search engines understand content relationships.
International SEO
Hreflang implementation and audit for multilingual and multi-regional sites. Ensures each language or region variant is indexed correctly and search engines serve the right version to the right audience.

Technical SEO Engagement — Step by Step
Access and Setup
Read-only access to Google Search Console, GA4, and your CMS. Screaming Frog crawl configured for your site's specific architecture and size.
Crawl and Data Pull
Full crawl run, Search Console error export, Core Web Vitals field data pulled from CrUX. All data cross-referenced to identify patterns rather than one-off issues.
Prioritized Audit Report
Issues grouped by type and ranked by estimated ranking impact. You see the top fixes that will move the needle most — not a spreadsheet with 300 items weighted equally.
Implementation
Fixes applied directly in WordPress, Webflow, or your codebase — or delivered as exact code diffs for your developer. Not recommendations only.
Verify and Document
Each fix verified in Search Console or a follow-up crawl. Before and after screenshots document every change. You have a clear record of what was done and why.
Technical SEO That actually gets implemented
Root Cause, Not Symptoms
I diagnose why pages aren't ranking — not just what the current rankings are. A 404 report tells you what's broken. An audit tells you why and what to prioritize fixing first.
Developer-Level Implementation
Schema markup is written in valid JSON-LD. Redirect chains are fixed at the server or .htaccess level. Core Web Vitals fixes go into the actual code — not just plugin toggles.
Core Web Vitals From Real Data
Lighthouse lab scores don't always match the Core Web Vitals field data Google uses for ranking. I audit both and prioritize fixes that improve the field metrics, not just the lab score.
Schema Validated Before Deployment
Every structured data implementation is tested in Google's Rich Results Test and the Schema.org validator before it goes live. Broken schema does nothing — and I don't ship broken schema.
Search Console as Source of Truth
Third-party ranking tools estimate traffic. Google Search Console shows actual impressions, clicks, and position data directly from Google. All reporting is grounded in real Search Console data.

Technical Fixes That Moved Rankings
"We had 140 canonical tag conflicts across our blog — half the posts were canonicalizing to paginated URLs instead of the original post. Johnbert identified them all in the crawl, fixed every canonical in WordPress, and we saw organic impressions increase 38% within 5 weeks."
"My site had 200+ redirect chains and a sitemap with 60 dead URLs. Johnbert cleaned the sitemap, fixed the redirect chains, and added BreadcrumbList schema across 80 pages. Three of my target pages moved from position 12 to position 4 in 6 weeks."
"Our product pages had CLS scores averaging 0.35. Johnbert found that our product image carousels were causing layout shift on load. After fixing the image dimensions and lazy loading, CLS dropped to 0.04 across all product templates. Mobile conversion rate improved alongside it."
