Indexing is the process of adding a record to a list. It is also an ordered list of references or citations used to give additional information about the items it refers to.

A physical index typically consists of a page or pages of alphabetic letters that point to other pages where the corresponding entries can be found. On the side, margins appear links to related terms, people, places, things and so forth.

SEO indexing is a process that involves adding a web page to the major search engines or directories.

To get high Google rankings, it is necessary in the first place to know how search engines work. Google uses the link structure of a site to determine which pages are important, and thus deserve a high ranking.

The Google indexing process consists of a few steps:

First, after indexing the page, Google will crawl the page, and decipher what can be considered essential information to rank the page. Usually, there is enough content to get a high ranking on these pages.

After understanding the content, Google will analyze the page for links to other pages. The Google ranking algorithm takes into account the number of links, their quality (links from authoritative and highly ranked pages), and freshness (newer links have more weight).

Finally, Google will analyze the page and give it a rank. Each time a page is crawled, it receives a new rank after accounting for new links and current content, so the pages are not significantly changed.
