FAQs

By default, Google Sites have to be mapped to a subdomain (e.g. www) and cannot be mapped to a naked domain.

A 'naked' domain is an internet domain name without the subdomain "www" (or any other subdomain). For example, computerlanguage.com is a naked domain but www.computerlanguage.com is not, because it includes the www subdomain.
See this page for instructions on how to redirect a naked domain to your custom url

Despite what your domain provider might tell you, you don't need (and can't get) the IP address of your Site to use your custom domain. Google Sites doesn't work that way.

• If you are using a personal Google account, follow these instructions:

  or for Godaddy users

• If you are using a paid for Google Workspace account, follow these instructions:

Note 1: VERIFICATION: If you have not managed to verify your Site using the Webmaster Central verification method you are currently directed to by Google Sites, the above article uses a different method using the Search Console, which is easier/better. Use this method instead.

Note2: USE THE RIGHT ACCOUNT: Make sure you are signed in to the same account when verifying ownership of your domain that is the owner account of your Google Site

Note3: IT'S NOT INSTANTANEOUS: After adding the cname record it can take several hours for the change to propagate round the internet so your website may not be available on the new URL immediately. 

Note4: CLOUDFLARE USERS: If you are using cloudflare use the 'DNS only' option, not 'proxied'

The first thing to have in mind is "Search Is Never Guaranteed".

The key to getting indexed on Google is unique and compelling content for Google Search to index for people to search for and find. Google Search only indexes text. It's not necessarily the number of words that are at issue, but fewer words mean there's less chance of your site offering something unique and compelling for Google Search to index. Google Search only indexes textual content for other people to find. If there is hardly any text, therefore, Google Search may not even bother indexing the site as there's nothing for people to search for.
This is not specifically a Google Sites issue and the best advice is to read all the resources on:

Why is my page missing from Google Search?

AND

Webmaster Guidelines

ESPECIALLY

Avoid the following techniques:

1. Creating pages with little or no original content

2. Doorway pages

Hopefully that will help you improve your Site's likelihood to get indexed.

Either:

a) You are not signed in with the owner account

or

b) You are using Google Workspace in which case the process is slightly different 

Follow these instructions if for a Google Workspace account:
