The New Signal Game

Jul 16, 2025

Authenticity vs. Algorithm in the Age of AI

Let’s not sugarcoat it; the way content gets seen online is changing fast, and not always in ways that make sense. If you’ve been clinging to keyword density or backlink volume like they’re still the holy grail, this week’s news might feel like a cold splash of reality. Because the question is no longer just how your content performs, it’s whether it even counts as a signal anymore.

LinkedIn: A Case Study in Human-Led Growth

Take LinkedIn, for example. HubSpot just published a breakdown of how one CEO pulled in 3 million impressions in four months. No ad spend, no automation, no “you won’t believe what happened next” clickbait. Just five things: a strong point of view, clear content pillars, earned credibility (think podcasts or panels), a consistent three-posts-a-week rhythm, and constant tweaking based on what actually worked. That’s it. No gimmicks, no growth hacks. Just a human being talking to other humans, regularly and with purpose.

And here’s the kicker; it didn’t just generate likes. It brought in demo requests, sales calls, real pipeline. The takeaway? Executive presence, when done right, isn’t a vanity metric. It’s a growth lever.

Google’s AI Overviews: A Feedback Loop of Sameness

Now, contrast that with what’s happening over on Google.

Ahrefs ran the numbers on Google’s new AI Overviews and found that nearly 88% of the sources cited were AI-generated. Not AI-assisted; fully AI-written. Only 8.6% came from purely human-written content. To be fair, this isn’t necessarily Google playing favorites. It’s more like a mirror held up to the current state of the web, where three-quarters of new content has some AI in its DNA.

But here’s where it gets messy. When AI starts citing other AI, you get a kind of feedback loop, a closed circuit of recycled phrasing and secondhand ideas, all dressed up as authority. And for marketers who’ve spent years playing the SEO game—optimize, rank, get cited—it’s a gut punch. Because what good is a citation if it’s buried in a sea of synthetic sameness?

Two Signal Models: Human vs. Machine

So now we’ve got two very different models of signal.

One is human-led: deliberate, consistent, rooted in credibility and craft. The other is machine-fed: fast, derivative, and increasingly self-referential. And while both might technically “work,” only one builds trust. Only one leads to actual business outcomes.

The Hard Choices Ahead

Which brings us to the hard part. If you’re leading a marketing team right now, you’re not just competing for attention; you’re competing for meaning. And that means making choices about how you show up. Do you chase the algorithm, or do you build something people actually want to read? Do you publish more, or publish better?

You know what? It’s not even about volume anymore. It’s about voice. And voice can’t be faked. Not for long, anyway.

Resources Worth Your Time

So what’s worth your time this week? A few extras, if you’ve got the tabs to spare:

The Bottom Line

The platforms are shifting. The signals are mutating. But people still want to hear from people. And that’s something no algorithm can replicate. Not yet, anyway.

That’s it for today, folks.

Catch you in the next post.

Until then, keep building.
