Hero summary
A technical SEO product proof, not only a website page
I built a practical SEO engineering tool suite that checks common technical issues businesses and developers face: schema, metadata, sitemap, robots.txt, canonical tags, Open Graph tags, and basic technical SEO signals.
Work
Technical SEO tool, validation UI, audit workflow
Focus
Crawlability, Metadata, Schema, Indexability, Share previews
Status
Live tool suite / ongoing expansion
The problem
Technical SEO issues are often invisible to business owners
Business owners often do not know whether their website is technically ready for Google, AI search systems, social sharing, or clean indexing. The goal was to create a free tool suite that exposes common technical SEO problems in a simple, readable format.
Missing metadata
Broken or missing schema
Weak canonical logic
Blocked crawl paths
Sitemap problems
Poor Open Graph previews
Unclear robots directives
Weak search-readiness signals
The solution
A URL audit workflow with structured results
I built a free technical SEO tool suite that lets users test a URL and review common website signals in one place. The system turns raw page data into clear validation results, warnings, and improvement suggestions.
URL input
Fetch/analyze workflow
Structured audit results
Pass, warning, and error states
Schema validation
Metadata extraction
Canonical check
Robots.txt check
Sitemap check
Open Graph preview check
Actionable recommendations
Tool modules
Core checkers in the technical SEO suite
The suite is organized around the technical signals that commonly affect crawlability, indexability, metadata quality, structured data, and share previews.
Free Technical SEO Audit Tool
Runs a high-level audit of a URL and summarizes common technical SEO issues.
Schema Generator and Validator
Checks JSON-LD structure and helps users identify schema markup issues.
Sitemap Checker
Checks whether a sitemap exists, is accessible, and contains crawlable URLs.
Robots.txt Checker
Reviews robots.txt availability and basic crawl directives.
Meta Tag Checker
Extracts title, description, viewport, robots meta, canonical, and social metadata.
Canonical Checker
Checks whether the page has a canonical tag and whether it points to the expected URL.
Open Graph Checker
Shows how the page may appear when shared and checks Open Graph title, description, image, and URL.
Technical implementation
Frontend audit UI backed by server-side URL analysis
The implementation combines a public form and results interface with server-side fetching, HTML parsing, metadata extraction, JSON-LD parsing, sitemap checks, robots.txt checks, canonical analysis, and Open Graph review.
Audit workflow
- Frontend form and structured results UI
- Server API route for fetching target pages
- HTML parsing and metadata extraction
- JSON-LD parsing and recommended-field checks
- Sitemap and robots.txt fetching
- URL normalization and canonical comparison
- Pass, warning, and error severity system
- Timeout and clear error handling
- Responsive UI for desktop and mobile use
- Reusable checker logic for audit sections
Fetch safety
- Only HTTP and HTTPS URLs are allowed
- Submitted URLs are validated and normalized
- Fetches use timeouts
- HTML and sitemap response sizes are limited
- Redirects are manually followed and capped
- Localhost, private IPs, and internal hostnames are blocked
- Failed fetches return clear user-facing errors
- Private crawl data is not stored by the audit workflow

Outcome
A practical audit entry point backed by technical SEO workflow design
The tool suite gives users a practical way to check their website before requesting a deeper audit. It also demonstrates the technical SEO systems behind effective website reviews: metadata checks, schema validation, sitemap logic, crawl signals, canonical structure, URL analysis, and clear frontend result design.
