The Technology Behind Google Search
Crawling & Indexing
Before you even type a search, Google's web crawlers (like Googlebot) have already discovered and indexed billions of webpages. These automated programs follow links across the web, collecting information about each page.
The Google Index
The index is like a massive library catalog containing information about all the webpages Google knows about. It's hundreds of billions of pages and over 100,000,000 gigabytes in size.
Google refreshes its index continuously, with some popular pages being crawled multiple times per day.
AI & Machine Learning
Modern Google Search relies heavily on artificial intelligence systems like BERT and MUM to understand the nuances of human language and the context of your search.
Key AI Technologies
- RankBrain: Helps Google understand how words relate to concepts
- BERT: Processes words in relation to all other words in a sentence
- MUM: Understands information across text and images in 75 languages
Google's AI can now understand searches as complex questions rather than just keywords.
