If you have idle domains on hand and are unsure what to do with them, most people might consider putting them in proxy storage, such as binding them with AdSense domain ads. The income generated from such methods is negligible, which is why you often see dramatic domain fire sales on various domain trading forums. Keeping something that doesn't generate profit is wasteful, not to mention that domain names require an annual fee of a few dollars.
In my opinion, the best solution for idle domains is DevHub, which I am going to recommend to you today. It specializes in generating content farms. As long as you set the keywords on DevHub, it can generate websites related to these topics. You don’t need to set up the program yourself, design the web pages, or even personally manage content updates. Of course, if you insist on adding articles yourself, that’s also possible. Moreover, the most critical point is that DevHub will automatically match ads based on the content, and you can set your own ads as well. As we all know, English ads generally have higher prices than Chinese ones.
