Google Search is a fully-automated search engine that uses software known as web crawlers that explore the web regularly to find pages to add to our index.

Search engines work by crawling hundreds of billions of pages using their own web crawlers. These web crawlers are commonly referred to as search engine bots or spiders. A search engine navigates the web by downloading web pages and following links on these pages to discover new pages that have been made available.

Search engine indexing is the collecting, parsing, and storing of data to facilitate fast and accurate information retrieval. Index design incorporates interdisciplinary concepts from linguistics, cognitive psychology, mathematics, informatics, and computer science.

You can explore Google Trends data using the free Trends Explore tool. The data is grouped into topics to give you the fullest picture of what people are searching for. You can also query individual search terms. As you type your query, a drop-down list will appear.
