What is crawling and indexing?

Google always searches for new webpages or new websites, that too using its algorithm. The name of google's algorithms is "web spider called Googlebot." 

• Crawling: According to this, the process of following the hyperlinks on the web to discover new content.
• Indexing: This a process of storing every web page in a vast database.
• Web spider: The piece of software designed to carry out the crawling process at scale.
• Googlebot: It's Google’s web spider.

If your web page or website is not yet indexed in Google, then you should follow these instructions -

1. Go to Google Search Console
2. Navigate to the URL inspection tool
3. Paste the URL you’d like Google to index into the search bar.
4. Wait for Google to check the URL
5. Click the “Request indexing” button

These process are good practice when you publish a new post or page. This way you’re effectively telling Google that you’ve added something new to your site and that they should take a look at it.  
Although, the requesting indexing is unlikely to solve underlying problems preventing Google from indexing old pages. If that’s the case, follow the checklist below to diagnose and fix the problem.

1. Remove crawl blocks in your robots.txt file
2. Remove rogue noindex tags
3. Include the page in your sitemap

5. Check that the page isn’t orphaned
6. Fix nofollow internal links
7. Add “powerful” internal links
8. Make sure the page is valuable and unique
9. Remove low-quality pages (to optimize “crawl budget”)
