Separating SEA and SEO? That’s a thing of the past.
Management Summary
I lead a seven-person paid search team. We run Google Ads, day in and day out. And I say: anyone who continues to think of SEA and SEO as separate will face a problem in the coming years.
SEA and SEO – What’s Changing Right Now
In 2025, Google began testing advertising in AI Overviews and AI Mode in the United States. These are the AI-generated answers that increasingly appear at the top of search results. Instead of ten blue links, users receive a synthesized answer—and embedded within it: ads.
The critical point: these answers are generated from website content. Google pulls information from websites, summarizes it, and embeds advertising into this context.
This fundamentally changes the rules of the game.
The Old World: Two Disciplines, Two Teams
Until now, the division was simple. SEO handles organic rankings. SEA buys visibility. Different teams, different KPIs, different budgets. The only intersection was the question of whether you were cannibalizing each other on brand keywords.
This separation had a certain logic as long as search worked this way: organic results here, ads there. Clearly delineated.
The New World: Content Determines Ad Context
In AI search, this separation no longer exists. Organic content and paid ads coexist in the same context—the AI-generated answer.
This has concrete consequences:
-
01
Your content influences where and how your ads appear.
When Google generates an answer and incorporates your website content, the likelihood increases that your ad will be relevant in this context. SEO feeds SEA.
-
02
Contextual relevance beats position.
In traditional search, it was about position 1, 2, or 3. In AI answers, there are no positions anymore. Either your content is included or it isn’t. Either your ad fits the context, or it won’t be served.
-
03
Users no longer distinguish.
When organic information and advertising merge in a single answer, the boundary between “organic” and “paid” dissolves. At least from the user’s perspective.
What This Means for Businesses
If you currently have an SEA team running campaigns in isolation, without insight into content strategy and website structure, you’re leaving potential on the table.
The questions SEA teams will need to answer will be different:
- Which content on our website is classified as relevant by AI systems?
- How can we optimize this content so our ads appear in the right context?
- Which search intents will be covered by AI answers in the future—and where will there be room for clicks?
These aren’t purely SEA questions. They aren’t purely SEO questions either. They’re search questions.
What This Means for Agencies
Most agencies—including ours—are historically organized in silos. The paid team here, the SEO team there. Separate reporting, separate client meetings, separate strategies. This will no longer work. Not because integrated work is a nice idea, but because the platforms are forcing it.
Agencies that establish “Integrated Search” early as a genuine discipline—not as a marketing buzzword, but as operational reality—will have an advantage. The rest will need to react when everyone else does.
Looking Ahead
Google plans to introduce advertising in Gemini in 2026. ChatGPT is experimenting with ad models. Microsoft has tested ads in Copilot. The direction is clear: AI assistants are becoming advertising platforms. And all these systems are based on content. They read websites, they synthesize information, they generate answers. Anyone who wants to be relevant in these answers—organically or paid—needs good content.
The irony: SEA will depend more heavily on content than ever before. And SEO will benefit more from paid strategies as the boundaries blur.
My Conclusion
I’m not saying that SEA specialists suddenly need to learn SEO or vice versa. Specialization still has value. But I am saying: the strategic separation of these disciplines is a relic. Those who understand search as a unified playing field will achieve better results. Those who continue to think in silos will wonder why performance is declining. Search is changing. We should change too.
