Search results don’t look the way they did even a year ago, and that shift is hitting ad performance directly. Paid click-through rates on queries with an AI Overview present fell from 19.70% to 6.34% between June 2024 and September 2025, according to Seer Interactive’s research. These AI search trends are forcing advertisers to rethink campaign structure from the ground up. This blog breaks down exactly what’s changing, why it matters, and how smart advertisers are adapting right now.
AI-generated answers now sit above traditional results on a growing share of queries. This pushes standard PPC ad campaigns further down the page. And that placement shift changes everything about how clicks get earned.
Google keeps expanding AI Overviews into commercial and navigational searches, not just informational ones anymore. Ads now appear inside roughly 25.56% of AI Overview results, up sharply from under six per cent in early 2025. These AI search trends mean advertisers are competing for far less visible screen space than they used to have, and that competition keeps intensifying every quarter.
More searchers are getting answers directly inside the AI summary and never scrolling further down the page. Zero-click search behavior has climbed past sixty per cent on many query types recently, and it keeps rising steadily. That trend directly reduces the pool of users who would have clicked a paid ad before, shrinking the addressable audience for most campaigns.
The fewer clicks there are, the less actual data will be available to inform bidding strategy in the long run. Campaigns that rely on click history exclusively may fail to perform well because of the changing click patterns constantly. New signals must be used by advertisers in addition to click history data that is old and outdated and causes ineffective budget management.
Metrics that show volume become less important once part of that volume goes into answering searches via AI. Advertisers are focusing on keywords with high purchasing intent rather than informational search terms. It allows the campaign to work effectively despite low clicks in general.
Account managers aren’t just watching this shift happen from the sidelines, they’re actively restructuring campaigns around it. AI in PPC campaign management now touches everything from keyword strategy to creative testing and landing page design.
A few structural shifts show up across most active accounts right now:
Teams weaving AI search trends into their planning process are adjusting faster than those still relying on last year’s playbook entirely.
None of this means paid search stops working. It just means the old structure needs rebuilding soon. Businesses that adapt their PPC ad campaigns early tend to protect performance while competitors scramble later to catch up.
A handful of things to do this year include:
Being ready to implement AI in PPC campaigns right now is much more important than waiting for dust to settle. Companies that will update their campaigns will maintain relatively low cost per acquisition numbers, while others will see those increase steadily month by month.
AI search trends are becoming more prominent, and their influence on paid results is only growing. Businesses which will adapt their campaigns accordingly right now will have a competitive edge over those who are just catching up.
