title: jekyll-seo-tag doesn't work within Github Pages
body: <p>So I faced a problem while trying to add some SEO optimization for my simple static website served via <strong>Github Pages</strong>.</p>
  
  <p>As the documentation says: <a href="https://help.github.com/articles/search-engine-optimization-for-github-pages/" rel="nofollow noreferrer">https://help.github.com/articles/search-engine-optimization-for-github-pages/</a></p>
  
  <p>I created the <strong>_config.yml</strong> file which includes next lines of code:</p>
  
  <pre><code>plugins:
    - jekyll-seo-tag
  </code></pre>
  
  <p>and pushed this file along with my website files, so the structure looks like <a href="https://i.stack.imgur.com/l0wtX.png" rel="nofollow noreferrer">this</a></p>
  
  <p>The problem is that after linking to my website I see the
  <a href="https://i.stack.imgur.com/xiiJe.png" rel="nofollow noreferrer">output</a></p>
  
  <p>And the head tag includes following <a href="https://i.stack.imgur.com/69jUv.png" rel="nofollow noreferrer">content</a></p>
  
  <p>I need help in understanding why the SEO plugin doesn't work. Thanks for all your replies and have a nice day!</p>
