How Google Search works
Every time you search, there are thousands, sometimes millions, of web pages or other content that might be a match. Google uses its robust systems to present the most helpful information in response to your query.
The world's largest library
Our Search index is like a library, except it contains more information than all the world's libraries put together. We're constantly adding to it and updating it with data about web pages, images, books, videos, facts and much more.
Instantly matching your search
In a fraction of a second, Google’s Search automated systems sort through hundreds of billions of web pages and other information in our Search index to find the most relevant, useful results for what you’re looking for.
Always improving your experience
We know that Search can always be better. That’s why we conducted hundreds of thousands of experiments every year, resulting in thousands of improvements, all of which are rigorously tested.
Keeping you safe on Search
Just like with email, phishing scams and other bad actors sometimes try to pose as highly relevant content. Search works to automatically detect these threats and keep them out of our top results.
