Smart Filter Noindex

Getting started

↑ Back to top

Smart Filter Noindex helps control how WooCommerce filter URLs are indexed by search engines.

Filtered archive URLs generated by layered navigation, sorting, price filters, ratings, and pagination can create large numbers of low-value URLs. This plugin allows you to automatically apply noindex directives to matching URLs while keeping important archives indexable.

Default Plugin Behavior

The Filter Whitelist allows selected filter keys to remain indexable even when filtering rules are enabled.

This is useful for high-value filter landing pages such as:

• Brand archives
• Color collections
• Seasonal merchandising pages

Adding Whitelisted Filters

1. In the Filter Whitelist section
2. Enter one filter key per line
3. Save settings
