Why AI Is Changing How We Search and What It Means for Your Marketing Strategy

In 2025, the search landscape is experiencing its most significant disruption in two decades. For years, Google has been the undisputed gateway to information. But a quiet revolution is underway. Millions of users are now bypassing Google and turning to AI-driven platforms like ChatGPT, Perplexity AI, and Gemini for faster, more contextual answers. While Google still dominates global search share, the cracks are visible and widening.

This isn’t just a tech trend. It’s a fundamental shift in behavior with big implications for marketers. If your entire strategy hinges on SEO and Google rankings, it’s time to re-evaluate.

The Rise of AI-Powered Search

Let’s start with the numbers.

  • Google’s global search share dropped below 90% for the first time in nearly a decade (StatCounter, March 2025).
  • On desktops in Europe, Google’s market share has fallen to 77.78%, down from 87.08% in 2023.
  • ChatGPT now sees 400 million weekly users and handles over 1 billion messages per day (OpenAI, 2025).
  • Perplexity AI has over 155 million visits per month and a 204% YoY growth rate (Similarweb, March 2025).

Why the shift? Users want:

  • Faster, clearer answers.
  • Conversational, context-aware interactions.
  • Relief from ad-heavy, SEO-stuffed content.

AI platforms are delivering on all three. Instead of links, users get summaries, comparisons, and synthesized insights and even advice. This is a search that feels like talking to someone who already did the research for you.

User Expectations Have Evolved

Traditional search was about finding links. AI search is about getting answers.The average prompt on ChatGPT is 23 words long, compared to just 4.2 words for traditional search queries (OpenAI Internal Research, 2025). That’s a huge leap in complexity and expectation. Users are engaging in nuanced conversations, not just typing keywords.

Voice and visual search are also on the rise. Google Lens processes over 10 billion searches per month (Google I/O, 2025). Meanwhile, TikTok and Instagram are quickly becoming default platforms for Gen Z product discovery. This shift is not just generational,it’s behavioral. People now choose platforms based on intent:

  • Google for broad queries.
  • Amazon for product search.
  • AI tools for academic research and decision-making.
  • TikTok/Instagram for discovery and inspiration.

Your content strategy needs to reflect that complexity.

Generational Changes in Search Behavior

A breakdown of AI search adoption by generation shows just how stratified this shift is:

What This Means for Marketers

For marketing leaders, this means your targeting and content must align not just with the platform, but with demographic behavior. A “one-strategy-fits-all” approach no longer works.

Let’s get tactical. Here’s what this evolution means for your digital marketing strategy:

1. Optimize for AI Summaries

Google’s new Search Generative Experience (SGE) and AI Overviews appear in 86.8% of all queries (BrightEdge, 2025). These summaries push traditional organic results far below the fold, reducing click-through rates by as much as 70%.

How? Structure your content so it gets picked up in these summaries:

  •  Use clear headings.
  • Provide concise, factual answers.
  • Avoid keyword stuffing, aim for clarity over cleverness.

2. Make Content AI-Readable

ChatGPT and Perplexity are now driving traffic to over 30,000 domains (OpenAI Partner Report, 2025). But they favor content that’s:

  • Plain-language.
  • Well-cited.
  • Context-rich.
  • Think less in terms of SEO and more in terms of information design.

3. Diversify Discovery Channels

AI search is just one part of the new discovery ecosystem. Users are stitching together knowledge from:

  • Social media (especially TikTok and Instagram).
  • Voice search.
  • Visual platforms like Pinterest and Google Lens.
  • Your brand needs visibility across all relevant surfaces. 

That might mean:

  • Repurposing blog posts into carousels or Reels.
  • Optimizing YouTube Shorts with Q&A content.
  • Turning stats into infographics readable by AI.

4. Track New Metrics

If you’re only monitoring Google Analytics, you’re missing half the picture. Start monitoring:

  • Referrals from AI platforms.
  • Voice and visual search stats.
  • Engagement from TikTok search or ChatGPT mentions (when supported).
  • Tools like Perplexity’s Publisher Analytics or OpenAI API logs can help fill in the gaps.

New Rules for Content Creation

In this AI-first search environment, authenticity and structure win. Old rules:

  • Write for keywords.
  • Optimize for clicks.
  • Focus on backlinks.

New rules:

  • Write for questions.
  • Optimize for clarity.
  • Focus on source credibility.

Even Google’s ranking systems are changing. As of May 2025, Google favors “information gain” and “experience-based content” over regurgitated copy (Google Search Central Blog). Preparing for a Multi-Platform Discovery Model, the reality is this: we are no longer in a Google-only world. Search now happens:

  • In AI chatboxes.
  • On social timelines.
  • Through voice assistants.
  • Via discovery feeds.

Marketers who treat AI search as a niche experiment will fall behind. Those who rethink their approach to discoverability beyond SEO will thrive.

This includes:

  • Revisiting buyer journeys to identify where search now happens.
  • Training teams to create content suited for AI responses.
  • Testing how your brand appears when queried on ChatGPT or Gemini.

Final Thoughts: From Keywords to Conversations

We’re at the beginning of a major transition. The same way mobile changed search in the 2010s, AI is changing it now. If you’re a marketing lead, comms strategist, or CMO, this shift isn’t optional. It’s already here. The question is no longer: “How do we rank on Google?” It’s: “How do we stay discoverable across an ecosystem of AI-powered platforms?”

Don’t wait for traffic to drop. Rethink your strategy now.
