What Google's new AI Search actually means for SEO and PPC

Google announced the "biggest upgrade to Search in 25 years" at I/O this week. Reading the coverage, you'd think the open web is dead, and we're all building mini apps inside search results now.

Slow down.

Google says some version of this every couple of years. AI Overviews were going to kill SEO. Before that, featured snippets. Before that, mobile-first indexing. The blue links keep dying, and somehow they're still here, just thinner each time. The announcement is still worth paying attention to. New intelligent search box that handles long conversational queries. Information agents running in the background for Pro subscribers. Generative UI that builds custom widgets and dashboards inside the results page. If you run paid or organic for clients, you need a read on what's hype and what's going to actually shift traffic and CPCs.

The SEO situation hasn't really changed

I'll keep saying this because every content marketer is selling a panicked AEO course right now.

Google's AI Mode and AI Overviews pull from the same index, with the same ranking signals, as regular Search. Google has said this directly, more than once. There is no secret AI index you can optimize for. The llms.txt files, the AI-specific content rewrites, and the chunking-your-content-for-LLMs advice. None of it is backed by anything Google has actually published.

What works is what worked five years ago. First-hand expertise. Specific details. Content a real practitioner wrote, not a content team filling in a keyword brief. AI search just makes it harder to fake, because the AI is summarizing the surface-level stuff anyway. If your blog reads like every other blog in your industry, Google can summarize it, and the user never visits you.

What is changing is the click-through math. AI Overviews already cut clicks on informational queries. Generative UI cuts them more, because Search can now answer with a custom widget instead of sending traffic to your how-to post. So if your strategy depends on top-of-funnel informational content driving traffic that you then convert downstream, you should be rethinking it.

Two query types still drive real clicks. Branded search, where someone is specifically looking for you. And commercial-intent queries where the user wants to compare, buy, or book. Both still flow through Google. Both are where your effort should sit.

PPC is more uncertain

Honestly, nobody knows yet. Sponsored placements show up inside AI Overviews and AI Mode, but the inventory and click behavior are still settling. Anyone telling you they have the new playbook is guessing.

What seems likely: CPCs go up on commercial queries because there's less inventory and the queries that remain are more bottom-of-funnel. The casual researcher gets handled by an AI Overview and never sees an ad. The buyer who's ready to act still searches and still clicks. Fewer auctions, higher intent, higher cost.

Branded campaigns get more important. If users are asking AI to recommend or compare services, your brand needs to be the one that gets named. That's partly an SEO problem, partly a reputation problem across the third-party sites the AI is reading, and partly a paid search problem when competitors bid on your name in a Search experience where there are fewer organic links to defend you.

What clients should actually do

Stop chasing AI-specific tactics nobody can prove work. If someone pitches you an AEO audit, ask them to point at the Google documentation supporting their recommendations. They can't.

Do these things instead. Tighten conversion tracking, because fewer clicks means each one matters more. Server-side, proper events, clean attribution. Diversify traffic sources beyond Google. Email, communities, partnerships, direct relationships. Write content a real practitioner would write, with specifics an AI summary can't replace. And watch your branded search volume, because that's the cleanest signal you have for whether your brand is showing up in the AI conversations you can't directly see.

The job hasn't changed. You're still trying to get attention from people who need what you sell. The mechanics are shifting and that's worth paying attention to. The fundamentals aren't.

If you're running an agency and trying to make sense of this for clients, this is part of why we built SmartMetrics. Reporting has to keep up with channels, and right now channels are moving faster than most reporting tools. Happy to talk if you're working through any of this.
