About NodSEO

What This Website Is

NodSEO is a growing collection of browser-based SEO and webmaster utilities. The Meta Tag Generator, UTM Builder, Bulk UTM Generator, and Robots.txt Generator process data entirely in your browser — your data never leaves your device. The Redirect Checker and Canonical Tag Checker each use a Cloudflare Worker for server-side HTTP analysis, but no URL data is stored or logged. There are no accounts to create and no usage limits. Every tool is free, practical, and built around real technical SEO workflows.

Available Tools

NodSEO currently offers the following tools:

  • UTM Builder — Generate single campaign URLs with all standard UTM parameters. Preview, validate, copy to clipboard, download as TXT or CSV, and generate QR codes as PNG or SVG.
  • Bulk UTM Generator — Import CSV, TSV, JSON, or TXT files. Generate hundreds of UTM-tagged URLs at once with template presets. Export as CSV, TSV, or JSON.
  • Redirect Checker — Trace HTTP redirect chains, view per-hop status codes, headers, and response times. Check single URLs or bulk lists. Export results as CSV, JSON, TXT, or Markdown.
  • Robots.txt Generator — Generate, preview, and download valid robots.txt files. Multiple user-agent groups, preset configurations, and live validation.
  • Canonical Tag Checker — Analyze canonical tags on any URL. Detect missing, multiple, relative, and cross-domain canonicals with SEO health scoring and recommendations.
  • Meta Tag Generator — Generate HTML meta tags for your web pages from a single form. Configure title, description, Open Graph, Twitter Cards, robots directives, mobile tags, and favicon links with live search and social previews.

Design Principles

  • Privacy-first. Most processing happens client-side. UTM and robots.txt data never leaves your device. Redirect Checker sends URLs to a Cloudflare Worker for tracing only, with no storage or logging.
  • Free and open. Every tool is free to use with no subscriptions, premium tiers, or hidden limits.
  • No friction. No account registration, no signup forms, no email required.
  • Practical. Tools are designed for real workflows — enter data, configure options, and export results.
  • Accessible. Built with semantic HTML, keyboard navigation, and screen reader support.
