Request : How to no-index specific parameters in E-Commerce ? |

Hello,

Thank you for your query and we are so sorry about the trouble this must have caused.

Those types of pages are dynamic ones so Rank Math can’t set the robots meta settings for them in the backend. However, we can do a workaround by applying a filter code. Please refer to the code below:

add_filter('rank_math/frontend/robots', function ($robots) {
	$excluded_params = [
		'add_to_wishlist',
		'add-to-cart',
		'product_brands',
		'product-tags',
		'filter_ml',
		'new',
		'top-seller',
		'rating_filter',
		'on_sale',
		'our-selection',
		'min_price',
		'filter_labels',
	];

	$url = home_url($_SERVER['REQUEST_URI']);
	foreach ($excluded_params as $param) {
		if (strpos($url, '?' . $param . '=') !== false || strpos($url, '&' . $param . '=') !== false) {
			$robots['index'] = 'noindex';
			$robots['follow'] = 'nofollow';
			break;
		}
	}

	return $robots;
});

You may refer to this guide on how to add filters to your website: https://rankmath.com/kb/wordpress-hooks-actions-filters/

As for your inquiry about the robots.txt, yes, you can remove the disallow rules for these parameters from robots.txt temporarily. This lets Google crawl the URLs and respect the noindex directive in the meta. Once de-indexed, you can block them again if desired.

Hope that helps.
