As search evolves past traditional SERPs and increasingly relies on large language models (LLMs), a familiar pattern is re-emerging: whenever a new system becomes influential, someone will try to manipulate it. Just as SEOs discovered loopholes in Google’s algorithms, such as keyword stuffing, link farms, spun content, and doorway pages, today’s opportunists are experimenting with ways to “black hat” their way into LLM-generated answers. And just like before, the industry will eventually be tasked with cleaning up the mess.
History is Repeating Itself
It Started With Algorithm Abuse. Now it’s AI Manipulation.
In many ways, the attempted manipulation of LLMs is a case of history repeating itself. For years, SEO professionals watched Google learn, adapt, and dismantle entire ecosystems of spam. Every time a loophole was found, the search giant tightened its quality systems, rolled out new ranking signals, and updated its spam policies. Think of Panda (2011) and Penguin (2012). Panda evolved from periodic updates into a core part of Google’s algorithm by 2016, when it became a continuous quality assessment rather than a reactive one. Today, this philosophy continues through:
- Ongoing Core Updates (quality, relevance, intent)
- Spam Updates (scaled content abuse, link spam, AI misuse)
- Helpful Content system (now folded into core)
How Black Hat SEO Is Being Adapted for LLMs
People are experimenting with ways to influence LLM outputs, like:
- Flooding the web with synthetic content designed to appear authoritative
- Building networks of AI-created sites that interlink to inflate credibility
- Mimicking expert style lacking real experience or accountability
- Targeting long-tail queries at scale to influence training and retrieval systems
But as history has shown, systems evolve. Google didn’t let keyword stuffing dominate its results forever, and LLM platforms will not allow content manipulation to undermine answer quality.
And this is where the next era of SEO comes into play.
Just as SEO teams spent time undoing the negative effects of earlier black-hat tactics, future SEO and content professionals will likely face remediation challenges stemming from AI-era manipulation. The following will become essential tasks:
- Cleaning up synthetic content footprints
- Reestablishing trustworthiness
- Establishing verifiable authority
- Demonstrating real expertise
Brands that unknowingly let AI-generated “content slop” accumulate around their web presence may find themselves struggling to be recognized as credible sources by LLMs and other AI systems. This reappearance of black-hat SEO tactics emphasizes the need for ethical SEO practices.
SEO’s Role Is Expanding
From Optimization to Defense
As LLMs become central to how people find information, make decisions, and choose providers, the role of SEOs will expand, not just to optimize for AI-driven discovery, but to defend against the inevitable wave of manipulation that follows any influential system. The future of search won’t eliminate black hat tactics. It will simply create new versions of them and new opportunities for skilled teams to set things right.
As LLMs and AI-powered discovery become foundational to how people find answers, evaluate brands, and make decisions, the cost of cutting corners will only increase. Black hat tactics, whether aimed at traditional algorithms or modern language models, may create short-term noise but inevitably cause long-term damage: lost trust, suppressed visibility, and painful remediation work.
Why Ethical SEO Is No Longer Optional
At Dagmar Marketing, we’ve seen this cycle before, and we’ve built our philosophy to avoid it entirely. Our approach is rooted in honesty and transparency, in line with how search systems are actually designed to work. We don’t chase loopholes. We build authority. We don’t manufacture signals. We earn them.
Ethical SEO isn’t about moving slower; it’s about building something that lasts. It’s how brands protect themselves from penalties, algorithm shifts, and AI-era misinformation filters. It’s how sites become credible sources not just in rankings, but in AI-generated answers and recommendations.
As search keeps advancing, the winners won’t be those trying to outsmart the system. They’ll be the ones working with it, grounded in real expertise, real value, and real trust. That’s where Dagmar Marketing operates, and that’s how we help our clients grow with confidence in an increasingly complex search landscape.
The rise of black-hat tactics aimed at LLMs is not a sign that SEO is breaking—it’s proof that influence always attracts exploitation. But as history has shown, shortcuts never outlast systems built to reward quality, trust, and expertise. In an AI-driven search landscape, credibility is no longer optional or implied; it must be earned and protected. Brands that invest in ethical SEO today aren’t just optimizing for rankings—they’re future-proofing their visibility, authority, and reputation in a world where AI decides who gets cited and who gets ignored.
