Adding URL to Google

Google is constantly adding new sites to its index and invites you to submit your own website to Google. Google does not add all sites to its index and they cannot predict or guarantee if and when they will appear.

Enter your complete web address (URL), including the https:// prefix. Example: https://www.google.nl/. You may also enter a description of your site. This is used for our information only, and has no effect on how your site appears in the index.

Only the index page of a website or domain is required. You don't have to fill out every page again. The crawler, Googlebot, will find the rest by itself. Important: Google refreshes its index on a regular basis, so reporting a 'dead link' (disappeared or moved site) is not necessary. Dead links will automatically be removed from the index during the next crawl when we refresh our entire index.
