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.

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.
