CRS 11.x uses spring to integrate seoUrlFormatter.
Why cant it be done in ATG way by creating components out of the class com.endeca.soleng.urlformatter.seo.SeoUrlFormatter?
Hi , with spring to integrate seoUrlFormatter has some native components that you can configure specific SEO url.
You can set properties and dimensions to be part of the URL.
Suppose BrandFormatters added here and User selects any brand from guided navigation, Brand name would start coming on SEO URL.
I hope I have helped, thank you
