To get Google quickly index a new website, we can use a Google tool:

Fill out the form to send the web to Google within the Google Search Console tool. It is an old Google form that we can fill out and tell you what our new website is:
https://www.google.com/webmasters/tools/submit-url?hl=en

In order to have access to this valuable form, we must create a Google Search Console account (formerly called Google Webmaster Tools). This tool is essential to have your page indexed since it allows us to be in contact with Google and improve our natural positioning in said search engine.
