title: Best way to link to categories from static blocks
body: <p>What is the best way to link to categories and products from static blocks.</p>
  
  <p>I ask because sometimes we will update URL-keys for categories, etc, which will break links in static blocks to given categories and products.</p>
  
  <p>Is there a better way to link using ids etc so the links will be active regardless of seo-friendly urls?</p>
  
  <p>Currently, I use links such as:
  <code>&lt;a href="store.com/generators/generators.html?"generator_package=6&gt;link&lt;/a&gt;</code></p>
  
  <p>When the urls for the categories change the above link would be broken.</p>
