Your competitors and your potential customers can ask ChatGPT the same question about your industry and get different answers. Neither may be wrong, because LLMs tailor answers to the person more than the question.

Here's what each of the 4 major LLMs read before it responds:
- ChatGPT personalizes on your general location, and on Memory if you have it turned on.
- Gemini can pull from Personal Intelligence, which spans Gmail, Photos, Search history, YouTube, and your past chats.
- Perplexity retrieves a memory store of your interests and past conversations, along with an AI Profile that can include your occupation and how you like answers formatted.
- Claude carries memory across conversations, scoped by project, and leaves incognito chats out.

Different LLMs continually learn different aspects about the same person, which most AI visibility checks overlook. For example, you open ChatGPT, type your company name, screenshot what comes back, and file it as data about your market, but in reality, it’s data about your personal account more than your brand.

The version of AI visibility tracking that holds up looks at specific prompts, captures changes daily, and runs across every model your buyers use. That's what Xponent21 built CARL Intelligence to do, across ChatGPT, Claude, Gemini, and Perplexity.

Rockstar by nature, guitarist by hobby – that's Chuck McCarthy! If aliens ever abducted Chuck and only let him bring a few things from home along to space with him, here's his shortlist:

🎸 Guitars, books, a record player
🥩 Ribeye
🍺 Veil IPAs
⚽ Soccer matches, streaming into the galazy

Feed him a steak, hand him a guitar, and Chuck's set for any dimension. Same guy who keeps our team and technical services rocking along back on Earth.

Wishing you a great birthday, Chuck!

Happy birthday to the member of our crew most likely to be found golfing in a whole new galaxy.

We asked the X21 crew what they'd bring back from one dimension to another if aliens ever grabbed them.

Garry's list:
🥟 Gyoza Dumplings
☕ Coffee
🎲 Dungeons and Dragons
🎮 Video games

Basically: feed him, caffeinate him, hand him a controller or a d20, and he's good in any universe.

Wishing a very happy birthday to the one and only, Garry Callis Jr.!

Aliens have abducted an X21 team member… and the spacecraft has never been more organized.

They report this human arrived with strong opinions about pickles, a very specific snack collection, and what appears to be an entire miniature world she built herself.

Here's what we know about our mystery crewmate:
👽 Brings creativity and structure in equal measure
👽 Has an eye for design that makes everything look intentional
👽 Lighthearted energy that somehow makes hard deadlines feel manageable
👽 Probably already has a system for whatever you're currently stressing about

To bring her back to Earth for her birthday, we've sent:
🥒 A jar of pickles (non-negotiable)
🍕 A tube of Pizza Pringles
🚲 Her e-bike (gravity confirmed on this planet)
🏙️ The Chicago flag, flown with full hometown pride
🎨 Tiny art supplies — because the miniatures aren't going to make themselves

Aliens report: "Subject has already reorganized the cargo hold. It looks great."

🚀 Happy Birthday to our Creative Director, Nikki!

When people search for signage requirements, Google's AI Overview names Solar Tint as a source.

It started with a pattern. Solar Tint's customers kept asking the same signage questions before they ever mentioned window film. We built content that answered those questions completely, structured the way language models need to trust and cite a source.

Now the AI Overview points to Solar Tint, and the company answering the user's question is also the company selling the product.

That's the mechanic behind generative engine optimization (GEO): give a language model a clear, complete answer, and it cites you.

Aliens have abducted an X21 team member…and shortly after, multiple systems reported: “something feels off. Possibly hacked.

They claim this human has a rare ability to identify problems before anyone else notices them… and fix them just as fast!

Here’s what we know about our mystery crewmate:
- Lives in the world of problem-solving and precision
- Calm under pressure, even when things break (especially when things break)
- Quietly keeps everything running behind the scenes
- Responds fast, fixes faster
- Has likely already solved the issue before you finish explaining it

To bring him back to Earth for his birthday, we’ve sent:
A perfectly cooked ribeye
Bubble water and Poppi sodas
Football energy (Go Pack Go) 🧀
A reminder of Pennsylvania roots

Aliens report:
“Subject resolved three unknown issues aboard the spacecraft within minutes.”
Yeah… we need him back.

Happy Birthday to the one who keeps our sites running strong. Welcome back to Earth, Drew!

Something's been building behind the scenes at Xponent21.

Chuck McCarthy has been in the studio recording new videos, and our new podcast – To The Power of X. We're focused on what's actually happening in AI SEO, GEO, and marketing strategy. No filler, no selling, just the conversations worth having as we enter the future of marketing.

Filming is underway. Episodes will drop soon. All you need to do is comment "PODCAST" and we'll remind you when we go live.

Aliens have abducted a key figure from X21. Someone they described as “a strategic mind capable of shaping systems, influence, and momentum at scale.”

They’re studying how one person can see what’s coming before it happens and then build the roadmap anyway.

Here’s what we know about our mystery human:
👽 Big visionary
👽 Builds things... FAST!
👽 Balances big ideas with ex*****on
👽 Has a habit of turning conversations into movements

To negotiate his return for his birthday, we’ve sent items we believe can ground him back on Earth:
🕶️ Funky sunglasses
🍺 Falcon Head IPA
🎶 Airpods
👟 Fresh kicks
.

🚀 Happy Birthday to the visionary behind it all, Will Melton! Come on back to earth soon!

We gave The Chemical Company's website some serious chemistry with AI — and the decision-makers who rely on finding answers about products, fast.

Through technical content restructuring and GEO strategy, their product and distribution content now surfaces in AI overviews as the premier source for industrial and engineering buyers looking for answers.

The right content, with the right structure, at the right moment – that's what makes all the difference in any business.
