SkillDev tools

og-url-match is a skill for auditing Open Graph tags on pages that have both canonical-url and og:url set. It checks how these two tags relate to each other and helps investigate why social share counts appear low. It applies to any page carrying both tags.

What your AI can do with it

  • Audit Open Graph tags on a page
  • Check pages that set both canonical-url and og:url
  • Investigate why social share counts appear low

Getting started

  1. Have a page that includes both a canonical-url tag and an og:url tag.
  2. Add the og-url-match skill to the agent's available skills.
  3. Ask the agent to audit the page's Open Graph tags or look into low social share counts.

What this skill tells your AI

When og:url doesn't match the canonical URL, social platforms track share counts separately for each URL variant—published share counts get split across multiple URLs and appear lower than they actually are.

Quick Reference

  • og:url must exactly match the URL
  • Use absolute HTTPS URLs for both og:url and canonical-url
  • Mismatched URLs cause social platforms to aggregate share counts on the wrong URL
  • og:url should be the clean canonical URL without tracking parameters

Check

Compare the og:url meta tag value with the href value. Both must be identical absolute HTTPS URLs. Flag any page where they differ, either in protocol, domain, path, or query string.

Fix

Set og:url to exactly the same absolute HTTPS URL as the canonical tag. Remove any UTM parameters, session IDs, or tracking tokens from og:url. If no canonical tag exists, add one and set og:url to match it.

Explain

Social platforms use og:url as the canonical identifier for aggregating share counts and comments. If og:url differs from the canonical tag, shares on the page URL and shares of the og:url accumulate separately, making your content appear less popular than it is and creating attribution confusion.

Code Review

Compare the value of with the value of . They must be identical character-for-character. Check for: different protocols (http vs https), www vs non-www mismatch, query string differences, trailing slash inconsistencies. Flag any page where the two values differ.
