Beyond looking at keywords, our systems also analyse if content is relevant to a query in other ways. We also use aggregated and anonymised interaction data to assess whether Search results are relevant to queries. We transform that data into signals that help our machine-learned systems better estimate relevance.

To give you the most useful information, Search algorithms look at many factors and signals, including the words of your query, relevance and usability of pages, expertise of sources, and your location and settings. The weight applied to each factor varies depending on the nature of your query.

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.

What is search engine ranking? The search engine ranking of a website, or URL, refers to its spot on the search engine results page. Web pages that rank well will appear at the top as one of the first few results on the first page.
