What’s driving paid search performance now

During my thirteen year career, the keyword drove paid search. Today, it is one of many symbols. Strategy is what determines performance.
The keywords are what you researched for weeks, then built your strategy closely based on your findings or assumptions. Manage everything from bids to search terms matched to negatives and target audiences. Your work is graded and graded on how well you rank for the keyword.
Paid media has always been very strategic, with Google driving the majority of searches. You had a process for placement, audience, bids, headlines, extensions, and keyword-rich URLs.
This model worked. It gave doctors the control they needed to get results.
You can see which search queries generated the ads and how much they cost. If there was a value, it was doubled or doubled. You can segment multiple ad groups by theme or build campaigns around keyword audiences, then set modifiers and match types to drive 1200% ROAS.
What has changed on all platforms
Marketing has come together through one structural change: AI, or more precisely, automation built into platforms. These systems now handle targeting, bidding, and creative integration that professionals used to manage manually.
The keyword has not disappeared. It was moved from a primary optimization measurer to one signal among many used by platforms to deliver ads based on user behavior and auctions.
For Google, AI Max Search is a clear example. It is not a new type of campaign. An optimization layer, such as Smart Bidding, that changes the way keywords work within a search campaign. Google’s AI uses your existing keywords, copy, and landing pages, including H1s and H2s, as signals rather than instructions to find and run ads.
Google reports that advertisers using AI Max see 14% more conversions at the same CPA or ROAS, with campaigns using exact match and phrase matching seeing up to a 27% lift. Pair it with Performance Max across Search, Shopping, YouTube, Display, Discover, Gmail, and Maps, or Demand Gen for top-funnel awareness, and the program expands further.

When I say strategy is the new keyword, I’m not talking about acronyms. I’m saying there’s direct input now that determines where your ads appear, who sees them, and whether they convert. This input has replaced the keyword list in paid media as the top control.
The difference is important. Strategy refers to the work required to achieve your purpose and vision. Tricks to kill. What has changed is that the platforms are now in control of the tactics, and our job is to define the strategy that guides them.
The quality of conversion data, including server-side tracking, has become the most important input for any account. Google’s smart bid and other platform optimization systems rely on conversion or event signals to learn and improve.
You can prioritize from all to one, which is the most important conversion, whether it’s a lead from a high-value market vs. a newsletter signup, or a new vs. returning customer. These splits used to be handled by keyword splits and bid modifiers. Now, to a lesser extent, they are handled through strategic discussion, where value is assigned or determined at that time.
First-party data, customer lists, CRM data, website behavior, and online outsourcing have become synonymous with keyword research. The richer and cleaner the data you feed these systems, the better. It’s less about search volume and more about understanding your customer data, making sure it’s well organized, and connected to the platforms you’re advertising on.
Creative is an animal. It goes from a product deliverable to a strategic signal.
In Demand Gen, Display, and Meta, your creativity is, practically speaking, your purpose. Platforms read your photos, video, and copy to determine who sees your ads. Google AI Max generates title and description variations based on your landing page content, your H1s, H2s, and so on.
Strategic questions, which themes are relevant to which segments, which visual methods drive action in different funnel stages, and which messaging frameworks allow AI to generate diversity, now carry the weight of the keyword used.
Landing page and website quality has become a paid media input, not just a UX or CRO thing. AI Max reads your page to determine which questions will be relevant and which headlines to create. The final URL extension in AI Max and Performance Max sends users to the page that AI deems most appropriate. A poor post-click experience, poor content, and slow load times can correlate with a low conversion rate.
All of this limits AI’s ability to serve your ads.

What it means for employees
Our roles have changed.
The most important task is no longer managing a list of keywords or adjusting manual bids. I have strong opinions about that, but I’ll ask you, what else could you be doing with your time, instead of adjusting bids for thousands of keywords?
It is a strategic framework that AI systems work within: ensuring data quality, defining creative strategy, building scalability into your teams, and knowing when the LLM is wrong and you, as an SME, need to make course corrections.
The job of the subject specialist is to guide the machines. That guidance takes the form of architectural changes, audience signal quality, creative frameworks, and product branding tools, rather than keyword lists and bid sheets.
This means investing time in understanding how:
- These plans are working.
- Learning platforms.
- LLMs are preferred.
It is the good and the bad that we choose to emphasize — the signs that we prioritize. It means building solid data for the first company, developing frameworks across audience, creative, and UX, and feeding that into AI for optimization. It means accepting that the keyword era offers something very different.
Employees who treat strategy as their core, investing their energy in architecture and design instead of pulling a lever, will be in the best position as this transition continues.
The list of keywords did not go away. There is no longer a work center. The strategy is that.
