Warren Shea’s Notes for SEO (Search Engine Optimization)

v20221211

• 301 Redirect = permanent redirect
• 302 Redirect = temporary redirect
• aria-labels don’t affect SEO
• Canonical URLs should exactly match their intended URL - don’t use canonical urls that 301/302 redirect
• A SEO Friendly show-for-sr class:

  <span class="show-for-sr-seo" sronly="dagger"></span>
  

  show-for-sr-seo:before {
  content: attr(sronly);
  display:inline;
  position: absolute;
  left: -9999px
  width: 1px
  height: 1px
  }
