Forget traditional funnels. Today’s customer journeys are nonlinear, AI-influenced, and constantly shifting. That’s why signal-based marketing is your smartest advantage.
Today’s customer journeys no longer follow a straight line. They’re scattered across channels, shaped by real-time behaviors and constantly evolving.
Boston Consulting Group notes that digital transformation has fractured traditional paths into unpredictable, nonlinear patterns — and AI is only accelerating the shift.
The real opportunity?
Not in trying to control the journey — but in showing up, consistently and authentically, wherever your customers already are.
Customers don’t move in sequence — they move in every direction.
The traditional marketing funnel thinks customers follow a neat path—from awareness, to consideration, to purchase. It makes things look clean in presentations and makes tracking easier. But in real life? It’s not that simple.
According to MarTech, 73% of retail shoppers use multiple channels during their buying journey. And they don’t go one by one—they do it all at once.
People might be scrolling TikTok while walking into a competitor’s store, checking reviews on G2 while your sales rep is talking, or asking ChatGPT for advice while your website loads.
This is called “cognitive offloading.” When decisions get complicated, people spread their research across different places to make it easier. Your customers aren’t being tricky—they’re just human.
What does this mean for the marketing funnel? It means there are more and more ways people discover and research your product, making the old funnel idea less accurate than ever.
Social Media Is the New Search Engine
The lines between marketing channels are getting blurrier. Social media, once mainly a place for building brand awareness, is now playing a key role in how people search.
In fact, 46% of Gen Z and 35% of Millennials prefer searching on social media instead of traditional search engines. This is a big shift because social search works differently—it’s push-based.
Instead of actively looking for something, algorithms show users content they might like before they even realize they want it. It’s like walking into a store and finding a surprising new book, rather than going to the library with one title in mind.
This ties into a psychological idea called “peripheral route processing.” When we’re casually browsing platforms like TikTok, we’re influenced more by things like social proof, visuals, and emotions than by detailed facts.
Plus, social channels like LinkedIn and YouTube don’t just influence users—they also impact how AI ranks and shows brands in search results.
Put it all together, and you see why a quick 15-second TikTok video can inspire more purchases than a long, in-depth research report. It’s clear we need to rethink the traditional marketing funnel and stop treating channels like isolated silos.
Every Interaction Either Builds or Breaks Trust
These days, the average customer might come across your brand in all kinds of places — a Reddit comment, a TikTok video, an AI chatbot answer, and a retargeted ad, all in the same day.
MarTech calls modern marketing channels “layered” instead of linear, which means the traditional marketing funnel no longer reflects how customers actually engage. Each layer is a chance to connect deeper — but also a risk of losing that connection.
The difference between winning and losing? Ruthless consistency.
And this isn’t just about having the same logo everywhere (though that helps). It’s about making sure your core message, values, and facts stay the same whether someone finds you through ChatGPT or an X thread.
Consistency builds trust — and trust is the real currency when you don’t control every conversation.
Take Apple as an example. Across thousands of touchpoints — in their stores, in YouTube reviews, or when you ask Siri — their message stays clear: simplicity, premium quality, and seamless integration.
They don’t control every single conversation about their products, but by keeping their story consistent, it’s nearly impossible to misrepresent what they stand for.
5 Key Signals That Reveal What Customers Really Do
While everyone else is trying to patch their broken marketing funnel back together, the smartest brands are abandoning it entirely.
They’re moving away from outdated, linear thinking and embracing something radically different: a unified signal system that treats every customer interaction as valuable intelligence—not just another touchpoint to optimize.
This new framework is surprisingly simple. Instead of forcing teams to think in rigid funnel stages, you organize around five core signals that truly reflect how customers behave in 2025:
- Search signals reveal what customers want before they even know your brand exists. This goes beyond traditional SEO data to include AI search queries, voice assistant requests, and those late-night questions people ask on platforms like Google, Perplexity, or TikTok.
- Traffic signals show how people actually move through digital spaces. Forget last-click attribution; this is about understanding the full customer journey—including the 70% of touches happening on platforms you don’t control. A single Reddit thread can deliver as much qualified traffic as a paid search campaign.
- Behavior signals track what people do, not just what they say. Cart abandonment, spending 12 minutes on your pricing page before switching to a competitor—these are behaviors traditional analytics often miss because they only focus on your domain.
- Social signals capture conversations you’re not directly part of. Every subtweet, LinkedIn comment, and Discord discussion about your category is data. As Google’s Prabhakar Raghavan noted, “40% of young people, when looking for lunch, don’t go to Google Maps or Search.” Yet many brands still treat social listening as a vanity exercise.
- Brand signals measure perception velocity—how quickly sentiment shifts, spreads, and sticks. This includes branded search volume and the tone of AI-generated summaries. When ChatGPT calls your competitor “innovative” but describes you as “established,” that’s a brand signal that shapes future market share.
Together, these signals offer a powerful alternative to the traditional marketing funnel—one that aligns with today’s complex customer journeys and delivers actionable insights in real time.
Why This Change Is Important
Funnel-based thinking creates organizational blindness within the marketing funnel:
- Your SEO team optimizes for search without knowing what your social team is seeing.
- Your brand team launches campaigns without understanding real customer behavior.
- Everyone focuses on their own piece, while the overall impact of the marketing funnel shrinks.
Signal-based organizations see the full picture.
When search signals show growing interest in a competitor’s feature, traffic data confirms that users are actively exploring alternatives.
Behavior signals reveal they’re comparing prices, while social signals expose growing frustration with your product and brand signals show sentiment declining — you don’t need six meetings to realize there’s a problem. The signals come together to tell a unified story that demands immediate action.
Turning Chaos Into Clarity: Your Step-by-Step Action Plan
Ready to take control of your marketing funnel? Here’s what to do:
- Check your AI footprint: Look up your brand on ChatGPT, Perplexity, and other AI tools. What do you find? Who’s mentioning you? Spend some time this week getting to know how AI sees your brand.
- Tailor content for each platform: Don’t just copy and paste the same thing everywhere. TikTok is different from Instagram, and each has its own way of showing content and what people expect. Make sure your content feels right for each place.
- Create one trusted content hub: Put together a clear, easy-to-find hub with everything about your products, FAQs, and brand messages. This helps your customers, your team, and even AI tools get the right info.
- Track all your channels together: The old way of tracking marketing doesn’t work anymore. Use tools that can connect the dots between search, website visits, social media, and more so you see the whole picture.
- Close the gaps between teams: Your social media, SEO, and content teams need to share info and work as one. Everyone should understand how AI and all the channels fit into your marketing funnel. Breaking down silos makes you stronger.
Why this matters:
- Everyone is looking at the same signals, so there’s no confusion.
- You get clear actions because the signals tell a real story.
- You make faster decisions without waiting for long reports.
- You spot problems early, before sales start to drop.

The Future Is Signal-Driven — And It’s Already Here
The marketing funnel assumes people move step by step. But in reality, customers move in all directions—at the same time.
The brands that will win aren’t just good at social media or ranking high on Google. They make every touchpoint count.
What matters now is showing up wherever your customers are, in a way that feels right for the platform they’re on—with messages that actually speak to them.
