What is Paid Search Advertising (PPC)?

In the world of digital marketing, if you want to quickly gain search engine attention, Paid Search Advertising is definitely your preferred strategy. It’s often called PPC (Pay-Per-Click) advertising because, as the name suggests, you only pay when someone clicks on your ad.

Simply put, paid search advertising is a way to attract website traffic and potential customers by purchasing ad placements on search engine results pages (SERPs). These ads appear in prominent positions in user search results, in the form of text, shopping listings, or videos, usually with a clear “Ad” or “Sponsored” label.

In a previous article, we explored how AI Max’s keyword matching works and found that it’s independently opening up new traffic channels. But AI Max’s capabilities go far beyond that; it can also automatically generate ad copy and headlines.

So, the question is: Where do these automatically-generated creatives come from? And while they offer convenience, what risks are hidden within?

Types and Frequency of AI-Generated Creatives

AI Max primarily generates two types of creatives: titles and descriptions. In my test account, AI-generated creatives were mostly titles, making up as much as 80% of the total.

AI is becoming increasingly important in the advertising world, and AI Max for Search from Google is a perfect example. Its core concept is simple: you provide some basic information, and the AI finds the most relevant users, automating your ad campaigns. For advertisers, this sounds very convenient.

But a question quickly arises: how exactly does this powerful AI work? Its internal decision-making process is invisible to us. We know what we put in and what comes out, but everything in between is like a “black box.”

If you have already followed the previous guide and successfully placed Google AdSense ads on your website, congratulations — you’ve taken the first step toward earning! However, many new site owners find that traffic comes, but revenue is not ideal. At this point, improving AdSense revenue becomes crucial.

Understanding AdSense Revenue Mechanism

Before optimizing revenue, it’s essential to understand how AdSense makes money. Simply put, your website traffic and ad interactions determine revenue, which mainly comes from ad impressions (RPM) and ad clicks (CPC).

Have you ever thought that your website or YouTube channel could be more than just a hobby platform and actually generate a steady, ongoing income? For beginner content creators, figuring out how to monetize traffic is often the top concern.

Among many options, Google AdSense is arguably the most common and beginner-friendly tool. It allows you to earn revenue by displaying ads while you focus on creating content, without requiring complex operations.

You may have experienced this: when chatting with AI, it can help you write poems, generate code, or even explain complex concepts like a teacher — its intelligence can be astonishing. But when you ask it for your company’s latest sales data, or to book a meeting room, it suddenly seems to “forget” everything and cannot respond. Why does this happen?

The reason is that most AI models do not directly access your proprietary information; they mostly rely on general knowledge learned from training data. To enable AI to truly “get things done,” it requires two key components: Agents and Knowledge Bases. The agent serves as AI’s “action brain,” capable of understanding instructions, invoking tools, and executing tasks; the knowledge base acts as AI’s “memory repository,” storing enterprise data, documents, and rules so the AI can access and utilize up-to-date information.
