Filter URLs

Filter URLs are created when users apply various filter options like price, brand, color or rating in online shops. These filters generate dynamic URLs with URL parameters that often lead to SEO problems.

SEO Challenges with Filter URLs

1. Duplicate Content Problem

Filter URLs can lead to massive duplicate content problems as the same products are accessible through various filter combinations.

2. Bot budget Waste

Search engines waste valuable crawl budget on irrelevant filter combinations.

3. Link Equity Distribution

Link equity is distributed across too many URLs, weakening the overall strength of the category page.

Best Practices for Filter URLs

2. Implement Canonical Tags

Every filter URL should point to the main category page:

<link rel="canonical" href="https://shop.com/category/" />

3. Robots.txt Configuration
