Video: how Google Search works, in five minutes

This is a short, official video from Google, about five minutes long, that explains how the search engine works on the inside: how Google discovers pages on the web, how it stores them in its huge index, and how, in a fraction of a second, it chooses and orders the results it shows each searcher. Its value is that it comes from the company itself, so it corrects many widespread misconceptions about “secrets” of appearing in search results, and lays the right foundation for anyone who wants to learn search engine optimisation.

What you will find in the video

• Crawling: how Google’s programs move between links to discover new and updated pages.
• Indexing: how Google understands a page’s content and stores it in the index.
• Ranking: how Google tries to understand what the searcher means, then chooses the pages most useful to them.
• A glimpse of Google’s work against spam pages and attempts to manipulate the results.

Who it suits

It suits everyone starting out in digital marketing or SEO, from secondary-school students interested in the field to university students, graduates, and owners of websites and small businesses. It needs no technical background, its English is simple, and YouTube captions can be turned on. It is also useful for decision-makers in companies who want to understand what the marketing team does without the technical details.

Understanding these stages helps any site owner work out for themselves why some of their pages do not appear in the results, before paying for outside services that promise quick results.

How to use it, step by step

1. Watch the whole video once without pausing, to get the overall picture.
2. Watch it a second time and write the three stages in your own words, with an example for each.
3. Then read “How does Google Search work?” on the academy’s blog, which explains the same stages in Arabic in more detail, with a checklist for your site.
4. Put it into practice: search Google for a site you know, preceded by site:, to see an estimate of how many of its pages are indexed.
5. Discuss with your classmates: what can stop a good page from appearing in the results?
