title: Magento 2 Category SEO friendly URLS
body: <p>I have a Magento 2 website and require some direction with setting up sub-category urls to be SEO friendly. The Navigation menu work just fine i.e </p>
  
  <p>Grooming Kit</p>
  
  <p>www.mywebsite.com/product-grooming-kit.html the issue i'm having is with sub-categories in the left sidebar filters which when a specific category is clicked on it displays as following url with a number id</p>
  
  <p>www.mywebsite.com/product-grooming-kit.html?grooming-kit=32</p>
  
  <p>I want it to look like </p>
  
  <p>www.mywebsite.com/product-grooming-kit/grooming-kit-mens/</p>
  
  <p>I have added this to custom urls manually, cleared cache and still no changes?</p>
  
  <p>In Magento 1.9 i would do a reindexer using ssh and would update urls. Not sure how to do this in Magento 2 without installing a third party extension.</p>
  
  <p>Any help would be much appreciated.</p>
  
  <p>Many Thanks
  Vinnie</p>
