Why paid search foundations still matter in an AI-focused world

At this time, artificial intelligence products such as Google and Microsoft PMax (And now AI Max) have woven themselves firmly into the toolkit of search marketers around the world. But as many search marketers rush to not only test new products but also scale their paid search activity, there is a growing tendency to neglect the core elements that make a successful paid search account: audience, structure, and intent.

In this article, I will aim to bring the foundations of paid research back into the spotlight, focusing on why the core concepts remain important and highlighting the fact that AI products do not necessarily replace organizations but only enhance them.

How we got here

It is of course important to emphasize that the shift towards the spread of artificial intelligence has been gradual. Since the early days of mania Match types and Manual CPC (Cost per click) to Smart bidding Play a bigger role in finding customers across different points of the user journey – we’ve come a long way to get here. With products like B Max With the claim of “doing everything for you”, we can see that the “hands-on” approach of last year is becoming less proactive.

With every step we take toward the current climate, we hand over more control to the machine. While this has allowed us to scale campaigns on a much larger scale, when you compare the role of a PPC Manager now to what it was 10 years ago, the day-to-day tasks look dramatically different.

But as automation has increased, so has the reliance of machines on clean, stable foundations. AI features can only improve based on what we feed it. If the structure, cues, or audiences are not clear, the machine will have no concept of what “good” looks like. For this reason, AI has not eliminated the need for basics; It made them more important.

Structure is still integral to success

Automated systems and products like PMax encourage greater levels of inclusion by feeding algorithms insights and allowing them to determine what works best for us. However, in practice, architecture remains one of the biggest drivers of whether or not AI drives success.

PMax is not psychological. It doesn’t have a complete understanding of the specific product margins your company may have, product development pipelines, or the full business realities of your company (yet!). The only way to do this is to clarify these distinctions. This is where structure comes in! A well-organized account provides limits for the device to work with. Helps by:

  • Providing clean educational environments: Grouping products and services in a logical way helps ensure that products like PMax aren’t trying to learn everything at once. With clear separation, you increase the likelihood of getting more accurate results.
  • Maintain budget control: If everything is rolled out in one campaign, it will make it more difficult to avoid underperforming products by cannibalizing the budget.
  • Reducing conflicting intentions: When campaigns mix different intents (for example, providing different and contradictory conversion actions from a user journey perspective), the device receives much greater amounts of hype. Through clear separation and definition within a well-organized account, advertisers can reduce skewed data and improve performance.

The audience’s vision remains the AI’s compass

When it comes to understanding people, human marketers will always have a competitive advantage. Knowing why people convert, what motivates them, and ultimately, understanding human nature will always mean that human marketers have intrinsic intuition that search features like PMax will never have. Recognizing this, it is important that humans feed high-quality customer insights into these platforms to ensure that machines can gain a better understanding of what makes us tick.

For example, a family car buyer and a luxury SUV buyer may be searching for (SUVs), but their motivations and expectations differ greatly. AI can easily collect this behavior, but it takes human vision to translate this behavior into effective positioning.

With that in mind, a fundamental understanding of a) what makes a strong audience group and b) how to implement said audience is again where foundational understanding comes into play. The strongest performing PMax campaigns are those filled with the richest ideas. CRM, loyalty information, and high-intent user signals often significantly improve PMax’s ability to improve performance. AI products can only feed back the information they provide, and these signals must be rooted in a true understanding of the audience.

When you deeply understand your audience, AI has a stronger foundation for optimizing it. When you don’t, you have to leave the device guessing.

Intent (and keywords) still drive everything

It could be argued that automation has accelerated the death of keywords, but what it has not done is make intent less important. Search has always been (and continues to be!) an intent-driven channel. PMax may automate placements and assets, but it still requires queries and signals to understand what someone wants.

We may be seeing fewer search queries now (much to my annoyance!), but the system is still learning from billions of intent signals. With this in mind, having a basic and foundational understanding of intentions enables you to:

Identify and prevent wasteful spending. Always my ace card. Negative elements and keyword exclusions remain crucial in helping guide AI products. Advertisers who optimize intent signals almost always outperform those who automatically assume that “leave it to the machine” is the best approach.

Match creativity with motivation. Understanding customer intent will help ensure you avoid generic ad copy and verbatim content that customers actually interact with.

Align landing pages with behavior. AI can send traffic to your pages, but if the content doesn’t match the user’s intent, the efficiency of the calculation will suffer.

A whole new world

To quote the 1992 Disney classic “Aladdin,” it really is a whole new world (they sure had PMax in mind when writing that song…). However, while the further acceleration of AI products may have changed the mechanics of search advertising, what it has not done is make the basics less important.

Audience vision still guides strategy. Intent still matters as much as content. Structure still constitutes precision. These are not only basics that have stood the test of time but will also provide a clear advantage to advertisers who can recognize their benefit.

The future of paid search isn’t really about fighting the machine; It’s about ensuring we influence the algorithms by providing richer context and insight, thus leveraging their ability to scale to deliver more results.
