Indexing

Indexing means that a search engine like Google adds a web page to its search index. For this to happen, the page must first be discoverable and processable. Whether it is actually indexed is determined by the search engine. Technically accessible pages may be excluded, for example, due to duplicate content or the “noindex” directive. The “noindex” directive is a tag in the page’s code that tells search engines: Do not include this page. Furthermore, an indexed page is not automatically ranked highly. Its position in the search results is determined by its ranking.
