The next field you need to insert a link that is formed during the search. An example: /color-blue-and-gray/. 
The button adds the SEO rule to the list
SEO rules include fields:
URL: This is the main field if it matches the search URL - SEO rule applies. An example: search/color-red/ - and when filtering by red, the rule will be applied. You can get this string if you do test filtering and copy part of the search URL. You can insert a variable {any} into this field. This means any text (part) in the URL. For example, you want to apply SEO rules for any filter with the color search/color-{any}/ OR for any filters search/{any}/
