Hello everyone, I'm new to programmatic advertising and would like to consult with you all on a business question. We are a manufacturer of educational tablets, designing and producing these devices ourselves and selling them directly to end-users. Therefore, we're able to pre-install various educational apps on our devices. These apps display a certain amount of advertisements, allowing users to access educational content for free; at the same time, if they dislike the ad experience, they have the option to pay a fee to remove ads. Currently, for the ad display part, we use advertising systems from ad aggregators similar to AdMob, but they often don't offer very good ad prices and come with many other limitations. As our product sales increase, we are considering the possibility of directly connecting with advertising demand, primarily to achieve better ad revenue. Through learning about ad networks, I understand that we are currently publishers within the ad network. I would like to seek advice on what methods we could try to achieve better ad revenues based on our current business model. Our company has its own team in the software development field with strong development capabilities. If it can effectively boost ad revenue, we are willing to invest in software-related development.
