How to Search a Single Domain
Here’s how to limit your searches to one website or TLD:
How to Search Multiple Websites at the Same Time
Similar to searching through a single website, Google lets you duplicate the command to search through multiple domains at once. Essentially, it’s as if you’re running a typical search across the entire web, but instead of sifting through the plethora of websites out there, you’re limiting the results to the few that you really want to pay attention to. Here are some examples:
site:edu schoolsite:gov “George Washington"site:lifewire.com OLEDsite:co.uk techsite:amazon.com “prime day"site:nasa.gov filetype:pdf marssite:media.defense.gov inurl:2017 report
For example, here’s a search you could perform to find everything that Lifewire and NASA has on electric vehicles: The trick to get this to work is to employ OR. This gives Google permission to list either source. If you don’t add this to the search, you’ll get zero results. Just like we did above with the single site search, you can tack on several other search parameters. Here’s a longer example that further constricts the results:
More Google Search Tips
Using the site: command in a Google search is one way to narrow down the results to help you find what you’re looking for, but there are plenty of other search commands, too. For example, filetype is used to search Google for files that have a specific file extension, inurl shows only results with that term in the URL, and quotes used around phrases group terms together. As you can see in some of those examples above, you can combine other search commands with site: for even more relevant results.
