Limit unnecessary URL 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.
