site: search operator
  
    
      A site: query is a search operator that allows you to request search results from
      the particular domain, URL, or URL prefix specified in the operator. For example:
    
| site:examples | |
|---|---|
| site:example.com | Show results only from the example.comdomain (www.example.comandrecipes.example.com). | 
| site:https://www.example.com/ramentsukemen | Shows results for pages that contain URLs that start with https://www.example.com/ramenand are relevant to the term tsukemen. | 
The site: search operator is available on all Google Search properties.
Uses for site owners
A site: query can help in a few ways with debugging a site. A few examples:
| site:examples | |
|---|---|
| site:example.com | Returns a list of indexed and serving URLs. | 
| site:https://example.com/recipes/tsukemen.html | May help you understand whether a specific URL is indexed and served. | 
| site:example.com viagra casino | Helps with identifying and monitoring spam problems on your site. | 
| site:https://example.com/lemon | Shows which URLs on the site can show up for the term "lemon". | 
| site:https://example.com/recipes/tsukemen.htmllemon | Shows whether the specific URL is indexed for the term "lemon". | 
Limitations
      The site: operator was designed primarily for search users and so it has some
      restrictions that site owners might find limiting. Specifically:
    
- 
        The site:operator doesn't necessarily return all the URLs that are indexed under the prefix specified in the query. Keep this in mind if you want to use thesite:operator for tasks like identifying how many URLs are indexed and serving under a prefix.
- 
        A site:operator without a query (for examplesite:example.com) doesn't rank the results. It will generally show the shortest URL for the prefix at the top, but otherwise the results are relatively random.
