+Indexing of domain names by search engines
+------------------------------------------
+
+Search engines, such as Google and Bing, rely on web crawlers (:dfn:`robots that explore and analyze
+the web`) to index all websites and their related domain names. These crawlers discover new URLs
+thanks to links on known web pages. As a result, search engines should index domain names
+automatically after a while, as long as their URLs are mentioned elsewhere on the Internet.
+
+Improving the appearance and positioning of web pages on search engines is a practice named "Search
+Engine Optimization" (SEO).
+
+.. tip::
+   Adding relevant content, optimizing metadata, and building high-quality backlinks can all help
+   improve a website's search engine visibility.
+
+Some search engines provide tools for web admins, such as
+`Google Search Console <https://search.google.com/search-console>`_ and
+`Bing Webmaster Tools <https://www.bing.com/webmasters>`_, to help you analyze and improve your
+page ranking. To use these services, you must prove that you are the owner of your domain name. One
+way to verify the ownership of your domain name is by adding a DNS record. You can do this for
+:ref:`domain names registered with Odoo <domain-name/odoo-manage>` and for domain names managed by
+other providers.
