Zero Click Search: How AI Overviews Affect SEO
For years, the SEO playbook was simple: rank high, get clicks, grow traffic. But in 2025, that model is breaking.
Between AI Overviews in Google, Bing Copilot responses, and a flood of featured snippets, search engines are answering user questions directly on the results page. That means fewer clicks, even when you rank well.
The numbers tell the story:
- According to Semrush, only 41.5% of searches now lead to a click on an organic result.
- A March 2025 study found 27.2% of U.S. searches end with no click at all, up from 24.4% a year earlier.
- Bain reports 80% of consumers now rely on zero-click results for at least 40% of their searches, which has cut organic traffic by 15–25% for many businesses.
SEO isn’t dead. But it’s not the same game anymore. The real challenge is learning how to stay visible and capture demand in a zero click search world.
What Zero Click Search Means for Startups
For early-stage SaaS companies, the rise of zero-click search is both a numbers problem and a visibility crisis.
Your site might rank, but that no longer guarantees clicks, traffic, or pipeline.
Here’s what that looks like in practice:
- Ranking ≠ traffic. You can own the #1 spot, but if Google’s AI Overview summarizes your post, users may never leave the SERP.
- Organic traffic is slipping fast. SimilarWeb reports some publishers saw referrals fall from 2.3B to under 1.7B visits after AI Overviews rolled out. Startups feel this as fewer site visits and fewer leads.
And the risks don’t stop there.
Search behavior itself is shifting:
- Trust is moving upstream. Users get answers directly from Google or Bing and never even see your brand.
- Funnels are shorter. With fewer clicks, you lose the chance to nurture readers through multiple blog posts before they convert.
The takeaway? Your website can’t be the only battleground anymore. To win in a zero click search world, you need two things:
- Content designed to be seen inside AI summaries and snippets.
- Owned channels (newsletters, communities) that capture attention outside of Google’s walls.
Enter GEO & AEO: The New Visibility Game
If zero-click search is the problem, then Generative Engine Optimization (GEO) and Answer Engine Optimization (AEO) are the emerging playbooks for visibility.
- GEO is about making your content legible to generative engines like Google’s AI Overviews, Bing Copilot, or even ChatGPT when it cites sources. Instead of just optimizing for keywords, you’re optimizing for citability. That means clean structure, clear answers, and trustworthy signals.
- AEO focuses on structuring content to appear in SERP features; snippets, knowledge panels, FAQs. It’s about formatting your content the way search engines (and now AI overviews) prefer to display answers.
The mindset shift here is crucial:
You’re no longer writing just for humans who click through to your site. You’re also writing for AI intermediaries that decide which brands to surface in their summaries.
That means founders need to ask:
- Does this content give a direct, scannable answer that an AI could lift into a summary?
- Is it backed by credibility markers (author bylines, citations, updated dates) that signal trust?
- Would a reader (even if they don’t click) walk away with my brand name attached to authority?
GEO and AEO aren’t about replacing traditional SEO, but expanding it. In the age of AI overviews, visibility is no longer just about clicks, it’s about being included at all.
Tactical Adaptations for Early-Stage SaaS
So what do you actually do with all this? For founders, the shift to zero-click doesn’t mean you should abandon SEO. No no, if anything, it means adapting your playbook to fit the new search reality.
The first adjustment is structuring answers up front. If AI overviews and snippets tend to pull the first clear definition or numbered list they see, make sure your articles lead with a concise, scannable summary before diving into detail.
Formatting matters too. Short paragraphs, occasional lists, and clean headings make it easier for both humans and AI engines to parse your content. This increases the chance your material gets pulled into a summary.
You’ll also need to double down on trust signals. Search engines are more likely to cite content that looks authoritative: bylined authors, recent updates, links to credible sources, and a professional site structure all help.
Finally, startups can’t afford to bet everything on Google. Even if you’re ranking, a big slice of your audience may never click through. That makes owned channels like newsletters, Slack communities, or LinkedIn posts critical. In other words, your SEO strategy now has to include “escape hatches” or ways for people who discover you in a zero-click context to still connect directly with your brand.
The companies that adapt early will survive zero-click search while building durable visibility across both AI-driven engines and their own owned platforms.
SEO Isn’t Dead — But It’s Different
Zero-click search and AI overviews are rewriting the rules. Ranking on page one no longer guarantees traffic. For early-stage SaaS teams, that means:
- Stop measuring success by clicks alone.
- Start formatting content for visibility in snippets and AI summaries.
- Invest in owned channels like newsletters and communities so you can capture attention outside of Google’s walls.
The companies that adapt won’t just protect their pipeline, they’ll stand out as credible voices when competitors are still chasing traffic that never arrives.
