title: Robots.txt Disallow file - should this be left empty?
body: <p>Need help on this robots.txt question. My default file looks something like this</p>
  <pre><code>User-agent: *
  Disallow:
  
  Sitemap: https://mywebsite.com/sitemap_index.xml
  </code></pre>
  <p>Problem is that with this configuration, Google deindexed almost all (at the time of this writing) of my URLs.</p>
  <p>Is it correct to leave the disallow field blank?</p>
