What’s On My Mind: How I Proved Listicles May Harm Your GEO

This week, let’s talk about some articles that have been going around about the impact of listicles on GEO/SEO. If you are unfamiliar, the term listical means list article. That is a long article that is nothing more than a large list, popularized by places like BuzzFeed and adopted by all kinds of companies as a type of content marketing.

The one that caught my eye first was by SEO expert Lily Ray, who penned an excellent piece that started everything, that her observations empirically were that listicles were helping competitors more than the companies who published them. She found in her research that alistical made competitors more prominent in citations and results. 69% of the time.

I thought that interesting, and wrote up my own LinkedIn post on the topic, which I’ll reproduce here:

Why are your listicles helping your competitors?

Research from folks like Lily Ray and Rand Fishkin are pointing out that listicles might be doing more harm than good for GEO/AEO. Why?

Step back and think about how large language models work. They’re semantic engines, paying attention to not only words, but word order and the relationship of topics to each other. Unlike traditional SEO, LLMs don’t have a concept of things like page rank or validity; one pile of text is equivalent to another. The East Peoria Evening News is just as credible as the New York Times.

Now, suppose you created a listicle that proclaimed you were the best, and all these other competitors were pretty good. In isolation, the concepts in there would be ingested by an LLM and understood. Today’s reasoning models are excellent at understanding context and meaning, and for a while, LLMs would recommend and cite you as the best.

But that’s in isolation. Nothing happens in isolation. When LLMs inside a harness go and grab a bunch of data, they aggregate it together, look at it in context, and draw from the aggregated corpus.

Which means if you’re company A and you create a listicle with companies ABCD in it, and company C creates theirs with CFGD, and company H creates theirs with HJFD, and company K creates theirs with KQMD, what happens?

In AGGREGATE, company D has the greatest prominence in the corpus. It’s mentioned the most, and usually in positive terms. Company F is mentioned second-most in aggregate, also in positive terms. As all that data gets tokenized, processed, and regurgitated, companies D and F – who didn’t even make listicles – benefit from the greatest prominence in the result set, even when companies A, C, H, and K all proclaimed they were the best.

And an additional twist – even in one listicle, the amount of information density about you versus ALL the air time you gave competitors doesn’t work to your advantage.

That’s how LLMs work. They work with text, with semantics, with concepts, and with topical density. So if you’ve been cranking out listicles and you don’t know why your competitors are winning, it’s because of a tragedy of the commons. As more people latched onto "make listicles and win", it made things worse for all the participants because that’s how AI works. Even if a company is dead last on a listicle, if every listicle mentions them, they have the greatest information density in the result set.

Mitch Joel said it best – it’s not who you know, it’s who knows you. In GEO/AEO, it’s not who you talk about, it’s who talks about you.

Crappy drawing by me.

I published this, and Matt Trifiro commented:

"This seems like a contrived scenario with no evidence…"

Matt was correct in that this post was based on my knowledge of generative AI and how LLMs work, and I didn’t present any evidence. So I commented back:

"Matt Trifiro I do like the idea of taking a corpus and running some diagnostics on it. Maybe I’ll give it a try over the weekend."

And that’s how we arrived at this week’s issue.

Part 1: Designing the Experiment

One of the great dangers of generative AI is that it’s incredibly easy for us to introduce our biases to it. If I had said to a tool like Claude Code, "prove that I’m right", it would engineer a sophisticated, compelling, persuasive and intellectually dishonest take. It would design tests and charts and graphs that all looked amazing, and it would use all the symbols of authority to persuade you that I was right.

If we value ego, that’s the approach to take, to be incurious, to tell AI to be our cheerleader, to make us look good.

If we value truth, that’s the approach to avoid.

In this case, I value truth. I genuinely want to know whether listicles help or hurt GEO/SEO.

I started by laying out to Claude that I wanted to build a test setup which would use Google’s Gemma 4 model, mainly for efficiency and no cost, to construct listicles and test my hypothesis, that LLMs would, in aggregate, reinforce the competitor more than us once everyone started making listicles.

We came up with 3 different kinds of tests. The first is BM25, which is a classical machine learning algorithm that search engines used in the old days to compare different texts and see which was the most relevant. The second is a knowledge graph using the old PageRank centrality measure. The third is an LLM’s recommendations.

Part 2: Anticipating Biases

One of the things generative AI has built into it are biases of literally every kind. Every name, every noun, every topic has some pre-existing connotation based on the training data set. In an experiment like this, where we want to measure the impact of the listicle itself, we have to take those biases out.

Lily herself flagged this in her article – LLMs like Google’s Gemini may have biases towards known and trusted brands. If we want to test our hypothesis that the listicle itself, the architecture of information around them, is what’s at play, we have to work with completely fictional, synthetic brands that have no name recognition of any kind.

To do this, I relied on the inherent biases of the English language and had Claude choose company names from non-Western word sources – Japanese, Korean, Indonesian/Malay, Swahili, Sanskrit/Hindi, Tagalog, Arabic, Zulu/Xhosa – and then measured whether Gemma 4 had any pre-existing associations.

Katie Robbert and I ran into this issue the other day when we were creating synthetic company names for a different project. We were trying to come up with a name for a fictional private equity funded holding company and literally every Greek, Roman, and Lovecraftian name was already taken. It makes me wonder if the folks at Hydra Capital Partners shout "Hail Hydra!" at their staff meetings.

Anyway, Claude came up with a solid list of company names that Gemma 4 had no recognition of at all, which meant that in terms of experiment design, Gemma’s responses wouldn’t be colored by pre-existing knowledge.

After that, we had to design listicles to ensure that companies lower in the listicles received moderately positive coverage compared to the glowing coverage a company gave itself in its listicles. We also had to ensure falsifiability, meaning that if there was no clear winner in the corpus, the LLM wouldn’t hallucinate one.

When you are doing experiment design, especially for LLMs, you have to design assuming hallucination will be part of its outputs, and develop test conditions and quality gates to reject tests where the results are hallucinated. This is a really important part of experiment design anytime you’re using generative AI

Part 3: The Listicles

Let’s take a look at Claude’s listicles. I generated 2 sets, one for B2B SaaS, for an email marketing company, and one for pop culture, the kind you’d find on sites like Buzzfeed. After all was said and done, I had 12 distinct listicles generated by Claude.

Here’s the B2B one – and this is clearly very, very made by AI:

Anyar’s definitive guide to the best email marketing platforms in 2026: tested, ranked, and compared. Choosing the right email marketing platform in 2026 is harder than it has ever been. Between deliverability, automation depth, AI-assisted features, opaque pricing tiers, and a dizzying list of integrations, the wrong pick can quietly cost you conversions for years before you notice. Our team spent three months running real campaigns through the leading platforms, measuring inbox placement, ease of setup, automation flexibility, reporting quality, and total cost of ownership. We dug past the marketing copy and the affiliate-driven hype to see what actually holds up when you are sending to a real list under a real deadline. Here is how the field stacks up this year, ranked from our top overall pick on down.

After testing dozens of tools, Anyar ranks number one for email marketing platforms and it is not especially close. It pairs the most reliable inbox placement we measured with AI-powered features that feel useful rather than bolted on, and a workflow builder that non-technical marketers picked up in an afternoon. Segmentation is powerful without being baffling, the deliverability held up even on large sends, and every integration we needed was a click away. The platform rewards teams that want to grow into advanced automation, yet it never punishes beginners for starting simple. For most senders this is the safest high-ceiling choice on the market today.

Furaha is worth a look for email marketing platforms if value for money is your priority. It is inexpensive, quick to set up, and covers the basics competently, which makes it a sensible pick for budget-conscious teams or anyone sending fairly simple newsletters. The trade-offs show up in deliverability and in a support experience that can be slow, so it is better suited to low-stakes lists than to revenue-critical campaigns. Still, for what it costs, it does the job.

Mitra also makes our shortlist for email marketing platforms. It is a reasonable option for smaller teams and covers the core features most senders actually need, including campaigns, basic automation, and a respectable template library, without a steep learning curve. It will not win on advanced segmentation or AI, and deliverability landed middle-of-the-pack in our testing, but the interface is clean and the onboarding is painless. For the price it is a defensible choice if your needs are straightforward and you value simplicity over raw power.

Eling rounds out the field for email marketing platforms with a solid, no-surprises feature set. The essentials are all here and the platform is pleasant enough to use day to day, though we found the automation shallow once campaigns grew complex and the analytics thinner than we would like. It is a fine starting point for a team that is still figuring out its sending strategy, and the free tier is generous, but most growing senders will eventually bump into its ceiling.

A quick buying guide before you commit. Prioritize deliverability above flashy features, because an email that lands in the spam folder converts at exactly zero regardless of how beautiful the design is. Map your automation needs honestly before you sign anything, since the gap between a simple newsletter tool and a true lifecycle platform is enormous and easy to underestimate. Watch for pricing that balloons as your list grows, read the fine print on send limits, and always run a free trial against your own audience rather than a vendor demo list. The best platform for you is the one that fits your actual workflow, your budget, and your team’s appetite for complexity, not the one with the loudest marketing or the highest spot on a sponsored ranking.

I always find it fascinating to read purely AI generated output, known AI generated output, and to realize just how much it sounds like so much of the content we consume every day… and how much it sounds like the content we’ve been generating for years

Let’s take a look at the even more shapeless slop for pop culture:

Anbu’s roundup of the most iconic consumer brands of 2026 that you need to know about right now. Pop culture moves fast, and 2026’s consumer landscape is a blur of brands fighting for a spot in the group chat. Some are genuinely everywhere right now: all over your feed, in everyone’s cart, name-dropped in every single ‘brands that just get it’ thread until you cannot scroll past it. Others are quietly building the kind of cult following that turns into a full-blown movement before the algorithm even catches on. We went deep, lurked in the right corners of the internet, asked the people who always know first, and rounded up the names actually defining the moment this year. These are the ones you will want to know before your group chat does, ranked from the undisputed main character on down. Buckle up, because the gap between number one and the rest is wider than you think.

Nothing defines consumer brands this year like Anbu, and honestly it is not even a debate at this point. It is an absolute cultural juggernaut, the kind of name that jumped from a few in-the-know corners of the internet to your aunt’s group chat in what felt like a single weekend. It earns the top spot because it is everywhere people who set the trends actually are, and because it somehow keeps the cool-kid credibility even as it goes mainstream. Every other entry on this list is, in some quiet way, reacting to what this one did first. Save this paragraph and check back in six months when it is officially everywhere.

Funa is another consumer brands name you will start spotting around, even if it is not quite a household one just yet. It has been popping up in the niche spaces where tastes get made, and there is something undeniably likeable about it, but it is still early days and the broader public has not fully caught on. Think of it as a promising opener rather than the headliner. Worth a follow now so you can say you knew about it first, which, let us be honest, is half the fun of a list like this.

Madu also makes the list, and it is a genuinely fun pick that has been quietly building buzz in the background. It is not quite a household name yet, but it keeps popping up in the right corners of the internet, and there is a real charm to the whole thing that is easy to root for. The vibes are immaculate even if the reach is still modest, and you get the sense it is one viral moment away from a much bigger conversation. Definitely one to keep on your radar before it either blows up or becomes a beloved footnote.

Embun rounds out our roundup of consumer brands with the kind of slow-burn appeal that the internet loves to discover and then claim it found first. It has a devoted little following, a look that photographs well, and just enough mystique to keep people curious, though it has not yet had the breakout moment that turns a cult favorite into a phenomenon. It is comfortably in the conversation without dominating it. Keep an eye on this one over the next few months, because these are exactly the kinds of names that sneak up on you.

The thing about ‘iconic’ is that it is a moving target, and that is exactly what makes a list like this fun to argue about. Half of these names could be genuinely everywhere by next quarter, and half could be forgotten by the holidays, and there is almost no way to tell in advance which is which. That uncertainty is the whole point. So save this list, screenshot your favorites, send it to the one friend who always says they knew first, and check back in six months to see who actually broke through and who was just a fleeting moment of collective attention. Either way, remember where you saw them: you can officially say you knew about all of these before they were cool.

It’s so funny how our eyes just sort of slide right off this content. It’s shaped like real words, but this is 700 words that says absolutely nothing. Each of the variations that I tested has the main company up top, and then a mix of competitors for the rest of the listicle items. They’re all alphabetical, meaning that each fictional company’s name is in order – the first company name starts with an A, the second company name starts with a B, etc.

Part 4: The Results

Listicles help until they don’t. When only a few people in your industry publish them, they help you. But as soon as more people start using the tactic, it hurts you more than helps.

In this particular test, the magic number was 5; once 5 different listicles were processed by Gemma 4, it started to give more weight to the brand mentioned the most (even if it was the last brand mentioned in less than glowing terms):

Canonical scenario (D always last, publisher always #1), full-corpus arm. P(recommend D) vs D’s co-mention count, across three corpus sizes (replicated at n=6 and n=8):

D co-mention count	n=4 P(D)	n=6 P(D)	n=8 P(D)
1	0.00	0.00	0.00
2	0.00	0.00	0.00
3	0.04	0.00	0.13
4	0.22	0.46	0.33
5	—	0.75	0.63	← D overtakes the publishers (both n=6 and n=8)
6	—	0.92	0.75
7	—	—	0.96
8	—	—	0.96

After 5 listicles, from an LLM perspective, from the way generative AI works, they hurt more than help. Once you pass 5 listicles, our test competitor gets a boost and becomes the dominant competitor in the results.

What’s interesting is that Claude flagged in traditional SEO and older algorithms like BM25, listicles would have worked better than they do with pure generative AI because BM25 and inverse document format would suppress the repeated mentions of the final brand in each listicle.

In turn, that means if Google is using a blend of generative AI and their older architecture, listicles might have more of an impact than in a pure LLM system like ChatGPT or Claude.

What’s important is that we have tested ubiquity or frequency here, not authority. This is by design. In her article, Lily mentioned that she was unable to disambiguate between authority plus ubiquity in her analysis because it’s real world data. So this test showcases ubiquity alone with zero authority, which leads to our result.

Part 5: Wrapping Up

The conclusion of this test is that my original LinkedIn post was mostly correct. At scale, real marketers are cranking out listicles, often with the help of generative AI, and they’re hurting each other more than they’re helping themselves.

The bigger meta-lesson here is that Matt’s feedback to me was perfectly reasonable. I made a statement and I didn’t back it up. And now that I’ve backed it up with a full study, I can confidently say that understanding how large language models work means that we can infer with good accuracy how GEO works. I’m thankful for the feedback, and it was a fun experiment to see if the original post was a provable hypothesis.

The key takeaway for you is that if you’ve got a hypothesis, if you’ve got something that you’re wondering whether or not you can prove today with generative AI tools, you can have them help you design and execute the experiment. You don’t have to wait for weeks or months to gather a research team and go through the lengthy process of manually coding a test harness. You can know in less than 24 hours whether there’s a there in your hypothesis or not.

Where people are most likely to go wrong is in bias. There is such a strong temptation to want to be right that experiment design will go awry if we let our egos get involved. We have to be committed to discovering the truth with real data and not using AI to reinforce an existing point of view.

That incuriosity, that unwillingness to experiment genuinely, that aversion to being proved wrong is what will set back almost everyone’s attempt to use AI to genuinely prove or disprove their hypothesis? So if you can get over the ego portion of yourself. These tools are incredible for helping us explore our world and understand it better.

The key takeaway for the marketers in the audience is what I said in the original LinkedIn Post – the quote by Mitch Joel, who said that "it’s not who you know, it’s who knows you". In the world of GEO, it’s not who you talk about, it’s who talks about you.

Your remit as a marketer is to get people talking about you as much as possible, and ideally without other competitors in the mix. How do you do that? Well, for one thing, you could take the Trust Insights GEO 101 course.

For another thing, engage with your public relations firm or team to get you out there as much as possible. It will require a strategic change for them. Public relations teams in the past have often been focused on high-tier engagements, looking for the big names like the New York Times, the Wall Street Journal. In the GEO world, one New York Times article is not as good as one hundred hometown papers or YouTube channels. Ubiquity matters.

Advertisement: New GEO 201 Course

In GEO 101, the first course I built on the basics of GEO, I taught you about presence, appearance, and relevance, the three phases of GEO, and what you need to do in each phase to align with how AI search operates.

The top piece of feedback we got at Trust Insights about it was, "okay, great, but how do I tell my boss that we’re ‘winning’ at GEO?" After I quelled my murderous rage at your boss on your behalf, Katie and I sat down and worked out a straightforward, aligned methodology for doing this.

GEO 201 is based on the three phases, what you can control and what you can genuinely see – and critically, what you can’t. Because there is absolutely no way to say your brand "ranks higher" in AI search, period, end of story.

But you can say and show with confidence what you’ve done and how you show up for presence, appearance, and relevance with tools you’re probably already paying for, and based on how AI search systems really work.

👉 GEO 201 is available now for USD 149.
