URL : Parameters

❓ What does it mean?

❓ What does it mean? A parameterized URL is a URL that includes query strings after a ? symbol, often used for: Tracking (?utm_source=google) Filtering (?color=red&size=large) Sorting (?sort=price_asc) Pagination (?page=2) Example: https://example.com/products?category=shoes&color=red

🚨 Why is it important for SEO?

🚨 Why is it bad for SEO (if unmanaged)? Duplicate Content Issues Different parameter combinations can show the same content. Example: /products?color=red /products?size=large Both might show the same "Shoes" category page → duplicates confuse Google. Diluted Link Equity Backlinks may point to parameterized versions, splitting PageRank across many variations. Crawl Budget Waste Search engines may crawl endless parameter combinations (?color=red&sort=price&size=large), wasting resources. Index Bloat Too many parameterized pages in Google’s index can reduce visibility of your key pages.

✅ How to Fix It

✅ How to Fix It Use Canonical Tags Point parameterized URLs to the main version. <link rel="canonical" href="https://example.com/products/shoes" /> Parameter Handling in Google Search Console Configure how Google should treat URL parameters (ignore vs. crawl). Prefer Clean URLs Instead of: /products?category=shoes&color=red Use: /products/shoes/red Robots.txt (carefully) Block crawling of unnecessary parameters (e.g., session IDs, tracking). Disallow: /*?sessionid= Disallow: /*?utm_source= Internal Linking Best Practices Always link to the clean, canonical version, not parameterized URLs.

❌ Bad Example

📌 Example ❌ Bad (parameter duplicates): https://example.com/products?category=shoes&sort=price_asc https://example.com/products?sort=price_asc&category=shoes (Both URLs show the same content → duplicate issue.)

✅ Good Example

✅ Good (clean + canonicalized): https://example.com/products/shoes (Tracking and sorting handled via canonical or JS, not indexable URLs.)
