Limit unnecessary URL parameters
SkillSearchParameters is a skill for search engine optimization work on URL structure. It guides an AI agent through auditing and fixing how URLs handle filters, sorting, and tracking parameters. It is used when auditing URL structure or configuring search engine handling of filtered, sorted, or tracked URLs, such as on e-commerce sites or filtered content directories.

What your AI can do with it
- Audit URL structure on e-commerce sites and filtered content directories
- Review how URLs handle filtering and sorting parameters
- Identify tracking and session parameters appended to URLs
- Configure search engine handling of filtered, sorted, or tracked URLs
- Fix URL parameter issues found during an audit
Getting started
- Have an AI agent that can load skills.
- Add the parameters skill to the agent's available skills.
- Provide the agent with the site or URLs whose parameter handling needs auditing.
- Ask the agent to audit the URL structure and apply fixes for filters, sorting, and tracking parameters.

Uncontrolled URL parameters generate duplicate content that wastes crawl budget and splits PageRank across URL variants, reducing the ranking potential of the canonical-url page.
Quick Reference
- URL parameters can create thousands of duplicate URLs from a single page
- Use canonical tags to consolidate parametric URL variants to a single URL
- Strip tracking parameters (utm_*, fbclid, gclid) before setting the canonical-url
- For critical parameters (page, sort), include them in the canonical URL
Check
Identify URL parameters in use across the site (filter, sort, color, size, utm_*, page, etc.). For each parameter type, check whether the page has a canonical tag. Verify that tracking-only parameters (utm_source, fbclid, gclid) are excluded from canonical URLs. Identify URLs with 3+ parameters and review for potential crawl budget waste.
Fix
Add canonical tags to parameter-based URLs pointing to the parameter-free or preferred URL. Remove tracking parameters from canonical tags. For sorting/filtering parameters that change content meaningfully (page=2, sort=price), either canonicalize to the base URL or self-canonicalize consistently.
Explain
URL parameters like ?color=red&size=large&sort=price&utm_source=google can generate thousands of unique URLs for the same underlying content. Without canonical tags, Googlebot crawls all variants, treating each as a separate page. This wastes crawl budget, creates duplicate content, and dilutes PageRank.
Code Review
Enumerate all URL parameter patterns used across the site. For each parameter type, check if pages with those parameters have canonical tags. Verify tracking parameters (utm_*, fbclid, gclid) are stripped from canonical URLs. Check that filter/sort parameter URLs either self-canonicalize or canonical-url to the base URL. Report the total number of unique parameter combinations crawlable.
