AdSense and the content monetization boom: is it all good news?

A video of everyday life can earn income. An article about personal experience can carry advertising. Content monetization is no longer reserved for broadcasters and publishers. The possibility of starting with a phone and an internet connection encourages people to imagine a place for themselves in the market. Yet an easier start is not the same as a dependable income.

YouTube’s advertising revenue illustrates the scale of expansion across the pandemic years. Alphabet’s filings show it rising from about $15.1 billion in 2019 to $40.4 billion in 2025. Google advertising generated about $294.7 billion in 2025, roughly 73% of parent company Alphabet’s revenue. Those figures cannot attribute growth solely to the pandemic or to more users, but they show the large advertising market sustained by people’s attention.

As individuals became organizers of that attention, creators and influencers became recognizable occupations. In South Korea’s Ministry of Education survey for 2024, creator ranked third among elementary school pupils’ desired careers. The question is whose income the expectation of opportunity produces. Alongside people trying to earn from content is another market: earning by teaching them how.

Success on screen, costs for the viewer

Income statements and displays of wealth can be persuasive. If someone who seems little different from the viewer has succeeded, following their method can look plausible. When the story leads to a paid course, the success narrative is both a shared experience and a sales argument.

There is nothing inherently wrong with charging to teach experience. Problems arise when one person’s outcome is presented as reproducible for others, or when the time, costs and failed attempts behind it disappear from the explanation. The audience also needs to distinguish revenue from profit, and advertising income from course sales. Evidence of wealth is not evidence that a course works.

The Korea Consumer Agency has documented actual complaints. It analyzed 59 requests for redress concerning expensive online side-income courses from 2021 through 2025. Twenty-four concerned teaching or coaching quality, and 17 concerned failures to fulfill a contract, including promised earnings not materializing or essential practice sessions and materials not being supplied. These are reported complaints, not a failure rate for all students or a measure of every course.

What deserves scrutiny is the conversion of anxiety into demand. The belief that doing it alone is difficult can combine with the fear that everyone else is already earning. A buyer may then pay more for reassurance than for the knowledge they need. A venture intended to earn money becomes a struggle to recover course fees before it has properly begun.

What the “AdSense exam” label obscures

Approval for Google AdSense, which lets publishers display ads on their websites, is entangled with this anxiety. In Korean online discussions, the process is sometimes nicknamed the “AdSense exam.” Article counts, lengths and publishing intervals circulate as if they were passing formulas. For an applicant who does not fully understand a rejection, someone else’s conditions at approval can look like an answer key.

A nickname is not evidence of the likelihood of approval. Google’s eligibility guidance calls for original, high-quality content and policy compliance, among other requirements. It does not prescribe a universal passing formula based on a minimum number of articles or words. Personal advice must be distinguished from the platform’s published criteria.

The conditions present when a site was approved are not necessarily the reasons it was approved. Domains differ in their existing content, operating history and site structure. Isolating an article count can make an experience look reproducible when it is not. When uncertain rules of thumb are sold as reliable secrets, applicants can end up chasing numbers instead of improving their content.

From receiving advice to carrying out the work

AI agents offer another possibility at this point. Beyond drafting text or generating an image, they can help create files and code, put them into a website and inspect the result. OpenAI introduced GPT-6 Astra on September 3, 2026. The significance of tool-using AI of this kind is its participation in practical work, beyond giving recommendations.

The change is not that an AI knows more approval tricks. It is that building a site, organizing existing material and correcting errors can become less burdensome. A user supplies goals and source material, works with an agent on a draft and revises it after seeing the result. Ideas become something that can be tested.

Agents can still produce wrong explanations and faulty code. They cost money and require review. They cannot replace Google’s decision or guarantee advertising income. Even so, the premise that a beginner can do nothing alone becomes weaker. There is an opportunity to make a small working result before buying someone else’s secret.

A new Lab, 21 articles and a first application

UPMI Lab is one example of that approach. Its operator already had material from actual work: HomeKit integration, editable PowerPoint presentations, classroom tools and NAS administration. Working with an AI agent using Astra, the operator organized a website and turned the context and results into articles, images and implementation records. The starting point was work already done, rather than topics invented for approval.

The new Lab contained 21 public articles, without counting Korean and English versions twice. Six main case studies were included in that total. The first application was submitted on September 16 and approved on September 29, without a second application. Approval came before a plan to build substantial traffic from the blog had been put fully into effect.

The conditions matter. The application used the existing company domain, upmi.re.kr; the Lab was a new subdomain beneath it. The company site already contained projects and reports. The 21 articles therefore describe the new Lab, not all content on the domain under review. Google did not disclose its approval reasoning. This case cannot legitimately become a new formula promising approval in 13 days with 21 articles.

The noteworthy change is the working method, not the discovery of a formula. The operator supplied material and direction; the agent helped with structure, editing and web pages; and the operator reviewed the result. This does not prove that the approval barrier has disappeared. It does show one way to move beyond not knowing where to begin.

Build grounds for judgment instead of buying reassurance

After approval, attention has to return to readers. Who is the article for? What can it offer that is difficult to find elsewhere? Why would someone come back? Permission to show ads and meaningful advertising income are separate stages. This article, too, appears in an advertising-supported publication. Criticism of monetization should turn on the value offered to readers and the honesty of the process, not the mere presence of advertising.

Good education reduces avoidable mistakes and helps learners judge for themselves. If teaching instead keeps people anxious and makes another payment a prerequisite for the next answer, it is worth asking whether it develops capability or dependence. AI makes that question clearer: even when choosing to pay for instruction, a person can use practical experience to decide what help they actually need.

Building something small, publishing it, observing the response and improving it leaves more than a website behind. It develops a sense of what one can do and where assistance is useful. A person can move from waiting on someone else’s income claims to making the next decision on evidence from their own work.

There is no need to abandon the ambition of earning from content. Nor is there a need to entrust the ability to pursue it entirely to someone else’s promises. The practical prospect offered by AI agents is not that everyone will become wealthy. It is the confidence to build, verify and revise something of one’s own. What matters next is a first working result, not a more persuasive promise of success.
