SEO Tools
Tools for the parts of a page that search engines and analytics read but visitors rarely see: the title and description shown in search results, structured data, campaign tags on links and the rules in robots.txt.
Each tool checks your input against the published rules, such as Google's documentation for snippets and structured data and RFC 9309 for robots.txt, and says what to change.
Tools in this category
Meta Title & Description Checker
See how your title and meta description show in Google results on desktop and mobile, measured in pixels, with where they get cut and what to fix.
Schema Markup Generator
Create JSON-LD for articles, organizations, FAQs and breadcrumbs, checked against Google's documentation, with valid URLs and dates and script-safe text.
UTM Builder
Add UTM parameters to any link with consistent lowercase naming, keep its query and # part, and check a campaign URL for mistakes that break GA4 tracking.
Robots.txt Validator
Check robots.txt line by line against RFC 9309 and Google's rules, and test any URL for Googlebot, GPTBot, ClaudeBot or your own user agent.
