Google Simplified the Creation Flow to Add Google-Powered Search Engine to Your Site and Earn from Showing Relevant Ads

It’s now easier to add a Google-powered search engine to your site and earn from showing relevant ads on your search results pages. They have made the following improvements to the AdSense search engine feature:

• simplified the creation flow to make it quicker and easier to create a search engine.
• added a preview, so you can see how ads will look on your search results pages before they go live.
• You no longer need to sign up for the AdSense for search product to create a search engine. You now create search engines on the “By ad unit” tab of the Ads  Overview page in Adsense.
