title: How to optimize SEO for SPA using React-Helmet?
body: <p>My project is a single page application using react js. I have heard that Google can crawl javascript pages including react js single page applications, without the need of server side rendering (even though it's generally better for SEO). </p>
  
  <p>However, when I used webmaster tool: fetch and render as google, both what google bots are seeing and what visitors to my page are seeing are blank.
  Even though I can add specific urls to google indexing, google only uses the title and description tag that I have put in my static index.html file, it doesn't get the nested react helmet component's title and description. Does anyone have experience in this? Appreciate it much!</p>
