How is AI shaping Paid Search?
Green Line Digital POV on Google’s AI Max for search.
Artificial intelligence continues to transform digital marketing, and Google’s latest roll out, AI Max for Search, is one of the clearest signals yet of where paid search is heading. Rolled out globally in May 2025, AI Max layers new AI-powered capabilities onto existing Search campaigns.
At Green Line Digital, we see AI Max as more than just another optional feature. It’s a preview of how Google intends to evolve Search campaigns in the years ahead.
What is AI Max for search?
AI Max is not a brand-new campaign type. Instead, it’s a suite of AI-driven enhancements that can be switched on within existing Search campaigns. With AI Max, Google takes a larger role in shaping results: targeting can expand beyond keywords, ads can be customized on the fly, and final URLs can be swapped dynamically to better match user intent.
The result? Campaigns that can reach further and adapt faster—but also campaigns that require more oversight to ensure they’re driving toward the right outcomes.
Our POV: Evolution, not just “Features”
Google describes AI Max as “added features,” but our view is different: this is the direction of paid search. Just as Performance Max evolved from optional to essential, we expect AI Max to gradually become the default way campaigns are managed.
That doesn’t mean keywords no longer matter. Traditional search campaigns still take priority when a query matches one of your existing keywords. For now, AI Max works alongside your search efforts, complementing, not replacing them.
The real value is in the flexibility and the insights it provides. By letting AI into your search campaigns, you can get custom search ads for each search- many of which you wouldn't even have thought of! Between keywordless targeting, location-based interest targeting, and dynamic creative pulled directly from client websites. AI Max also gives us visibility into which headlines resonate, which landing pages convert, and how Google interprets a brand’s digital footprint. Those insights can shape not just campaign performance but broader marketing strategy.
How to approach AI Max.
Our recommendation is to test deliberately. Start by layering AI Max onto existing campaigns that have a smart bid strategy in place (Max conversions or Max conversion value). Double-check that your landing pages make sense, exclude irrelevant URLs, and maintain strong negative keyword strategies to protect your budget.
Monitoring is critical, especially since Google’s AI can (and will) expand reach beyond your existing keyword set to find new potential customers. By staying close to the data, you’ll know when AI is adding value and when it’s not.
If you’re hesitant, consider running AI Max within an experiment campaign first. Google has also begun offering more transparency into reporting, making it easier to see what pages are being used, what creative was generated, and what keywords were matched. Those levers give advertisers more confidence as they test.
The takeaway.
AI Max for Search represents a shift toward AI enhanced paid search, and we believe it’s only the beginning. While traditional search campaigns remain important today, the brands that start experimenting now will be best positioned when AI-driven targeting inevitably becomes the norm.
At Green Line Digital, our approach is the same as it was with Performance Max: test early, learn quickly, and apply insights before the market catches up.
The future of paid search is AI-powered. The time to prepare is now.
