Understanding what search engine indexing is is essential for any business investing in SEO. You can have the best website and content, but if search engines cannot index your pages, your site will not appear in search results.
Search engine indexing is the process by which search engines store and organise web pages after discovering them. Only indexed pages are eligible to rank.
This article explains how indexing works, why it matters, and how businesses can ensure their websites are indexed correctly.
What Is Search Engine Indexing?
Search engine indexing is the step that occurs after crawling. Once a search engine discovers a page, it analyses its content and stores it in a massive database called an index.
If a page is not indexed:
-
It will not rank
-
It will not appear in search results
-
Organic traffic will be impossible
