Here are some ways to get Google to index your website faster:

• Submit a sitemap
  A sitemap is an XML file that lists all the pages on your website. It helps search engine crawlers identify and index your content more efficiently.
  
• Build backlinks
  Google considers pages trustworthy if they're linked to from authority websites. Backlinks make your content more discoverable and tell Google that a page should be indexed.
  
• Build internal links
  Link updated content from high ranking pages on your website. This alerts Google to the updated material and helps it get discovered quickly.
  
• Share on social media
  Publish your most valuable content on social media in a way that encourages your followers to share it with their networks.
  
• Optimize your robots.txt file
  A Robots.txt file tells search engines which URLs they can or can't crawl on your website.
  
• Monitor your indexing status
  Keep track of your website's indexing status.
  

Other things you can do include: Removing nofollow tags from internal links, Deleting misplaced noindex tags, Checking robots, Blocking or redirecting low-quality pages, and Making sure there's no duplication of pages.
