Website not showing up on Google: work through this in order
Your site is live, you search for it, and it is not there. Everything you read tells you to wait, or to buy something.
Confirm it is an indexing problem, not a ranking one
Search for your exact domain with the site: prefix. If pages come back, you are indexed and this is a ranking problem, which is entirely different. If nothing comes back, continue.
The four cheap causes, in the order they occur
A noindex tag left on from staging. A robots.txt disallow. A canonical pointing somewhere else. Content rendered only by JavaScript, so the crawler receives an empty page. Each takes minutes to check and any one of them will keep a perfect site invisible indefinitely.
Then ask, explicitly
Verify the property in Search Console and Bing Webmaster Tools, submit a sitemap, and request indexing for your most important URLs. Asking is not a formality. On this site an entire engine returned nothing for 31 days and came back the day it was asked to recrawl, not before.
Search your exact domain first
Type your domain into Google. If it comes back, you are indexed and the problem is ranking, which is a completely different problem with completely different fixes. If nothing comes back, the problem is access: a noindex tag, a robots.txt rule, a login wall, or a site that renders only after JavaScript runs. Do this before you read any further advice.
Indexed is not the same as findable
Most sites that believe they are not indexed are indexed and ranking at position 40 for terms nobody searches. That feels identical from the outside and is fixed by completely different work. Search Console's Performance report will tell you in a minute: if there are impressions, Google has you, and you now have a ranking problem you can measure.
Measured, not asserted
A 31-day blackout on one search engine, 17 May to 16 June, ended after a single reindex request in that engine's console. No content changed. The outage was as long as it took to try the cheapest available action.

Where this goes deeper
Every number on this page comes from one complete dataset: one product taken from zero to 100K+ users on search alone, with nothing spent on advertising. The full argument is Chapter 22 of the book. Five chapters are free to read.
