To get AdSense for your blogspot website, you need to follow these steps:
Sign up for a Google AdSense account: If you don't have a Google account, you will need to create one.
Add AdSense to your Blogspot site: Log in to your Blogger account and go to the "Earnings" section. From there, you can link your AdSense account to your Blogger account.
Create ad units: Decide where you want to display ads on your site and create ad units. AdSense provides a variety of ad formats, including display ads, link units, and more.
Add the ad code to your site: Copy the ad code provided by AdSense and paste it into the HTML of your blogspot site.
Get reviewed: After you've added the code to your site, AdSense will review your application and check that your site complies with their policies. This process can take up to a few days.
Start earning: Once your site is approved, your ads will start appearing and you'll start earning money. You can monitor your earnings and performance in the AdSense dashboard.
Note: Google AdSense has strict policies and guidelines, so be sure to read and follow them carefully.
