Steps to  make money with Google AdSense:

• Read and follow Google's guidelines: Webmasters must follow Google's webmaster guidelines as well as the AdSense program's guidelines.
• Do not click on your own adverts or request that others do so: It's against the rules to pay for clicks, acquire Pay Per Click (PPC) space, or use a programme to drive traffic to AdSense pages. Remember that breaching the rules will get you in trouble with Google, so be sure you follow them.
• Have fantastic content that your target market will like reading: Ultimately, money is made through delivering valuable content and excellent visitors to your blog or website, whether through AdSense or other monetization strategies.
• Use organic traffic-building internet marketing strategies that are honest: Search engine optimization and article marketing are both good ways to acquire free visitors to your website.
• Ensure that your website/blog is mobile-friendly (responsive): Mobile devices are used by a large number of people. Make sure you're utilising responsive advertisements, so Google can send the right ad sizes to mobile devices that visit your site.
• Test several ad types and placements to see which ones provide the most revenue: Start with typical sizes  and check if one size causes more clicks than another.
• Maximize your ad placements: Each page allows for three standard ad spots. To get the most out of them, use them all.
• Advertisements should be placed above the fold: This is the part of your page that can be viewed without having to scroll.
