title: Made changes to robots.txt but search engines still say description not available
body: <p>Most of the questions I see are trying to hide the site from being indexed by search engines.  For myself, I'm attempting the opposite.</p>
  
  <p>For the robots.txt file, I've put the following:</p>
  
  <pre><code># robots.txt 
  User-agent: *
  Allow: /   
  # End robots.txt file
  </code></pre>
  
  <p>To me, this means that the search engines are allowed to search the directory. However, when I test it out it still displays the website as "A description for this result is not available because of this site's robots.txt"  but when I clicked on the link, it's displaying the above code.</p>
  
  <p>I'm guessing it's because it takes awhile for Google and Bing to catch up? Or am I doing something wrong?</p>
  
  <p>If it's because they haven't caught up to the changes made yet (these changes were made yesterday afternoon), then does anyone have a rough estimate to when the changes will be reflected?</p>
