With the vast amount of information available, finding what you need would be nearly impossible without some help sorting through it. Google’s ranking systems are designed to do just that: sort through hundreds of billions of web pages and other content in our Search index to present the most relevant, useful results in a fraction of a second.

Key factors in your results

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. For example, the freshness of the content plays a bigger role in answering queries about current news topics than it does about dictionary definitions.

Learn more below about the key factors that help determine which results are returned for your query:

• Meaning
