Both AdSense for search and Custom Search allow you to create a Custom Search Engine (CSE) and earn revenue from the AdSense ads on the search results page. Custom Search is also available as a separate product with more advanced features.
AdSense for search and Custom Search both offer you the following:
- choosing the content your users search: enable users to search your site, a collection of sites you choose, or the entire web. You can also prioritize and restrict search to specific sections of sites.
- monetization of search results pages with targeted ads
Using Custom Search separately, you also get the following advanced features that can be accessed after creating your search engine:
- customize the look and feel
- site exclusion
- labels and refinements
Within AdSense for search, you can create channels and view reports for all of your search engines, whether you create them through AdSense for search or Custom Search.
If you already have an existing AdSense account, we recommend that you create all your search engines in AdSense for search.
