SEO & AI Search
Fort Wayne, Indiana
TL;DR
- Google’s Search Central guide states plainly that llms.txt files do not help or hurt your visibility in Google Search, including its AI features.
- Optimizing for AI search is not a separate discipline from SEO. Google’s own words: it’s “still SEO.”
- The guide was updated July 10, 2026, specifically to correct claims like these.
- If you want to check how you show up in AI search results, Google’s new Search Console report is where to look, though access is still limited and it only shows impressions so far.
- Nothing about how we approach SEO for clients has changed because of any of this.
01 · Where this comes from
Two Questions We Keep Getting
Two questions have come up more than once from clients lately: do I need something called an llms.txt file, and is this new AEO or GEO thing different from the SEO we’re already doing? Neither came from a sales pitch or a cold email. Both came from business owners who’d seen the terms somewhere and wanted a straight answer.
Google gave one. On July 10, 2026, its Search Central team updated the official guide to optimizing for generative AI search, adding a section written specifically to correct claims like these. It’s short, direct, and settles both questions without hedging.
02 · Myth one
Google’s Direct Answer on llms.txt
Under a bullet titled “LLMS.txt files and other ‘special’ markup,” in the guide’s section on what you don’t need to do for generative AI search, Google states:
“You don’t need to create new machine readable files, AI text files, markup, or Markdown to appear in Google Search (including its generative AI capabilities), as Google Search itself doesn’t use them.”
That covers llms.txt directly. An llms.txt file is exactly this kind of file: a plain text list, similar in idea to a robots.txt file, that some sites publish for AI systems to read.

Straight from Google’s own guide, updated July 10, 2026.
The same page adds a separate, more direct note right underneath, specifically about maintaining one anyway:
“It’s completely fine if you decide to create and maintain LLMS.txt files (or other similar files) for other services or systems that use these files. Doing so will neither harm nor help your site’s visibility or rankings in Google Search, as Google Search ignores them.”
Put together, Google is saying, about its own search engine specifically, that publishing an llms.txt file changes nothing, whether or not you keep one around for some other reason.
Watch Out
One qualification worth being precise about, since it’s easy to overstate this: the statement above is about Google Search specifically. It doesn’t say anything about how other AI systems, like a chatbot’s own web browsing feature, might treat these files. If a client already has an llms.txt file for some other reason, there’s no reason grounded in this guide to remove it. There’s also no reason grounded in this guide to spend time adding one for Google.
Brightbox Perspective
Our honest answer when a client asks: it’s not necessary, according to Google, and it doesn’t affect anything for Google Search at this point. We can build one if someone wants it, but it more than likely won’t change how the site shows up.
03 · Myth two
Is AEO or GEO a Different Discipline From SEO?
AEO, short for Answer Engine Optimization, and GEO, short for Generative Engine Optimization, get pitched as new practices built for the age of AI search, distinct from ordinary search engine optimization. On whether either one counts as its own field, the same guide answers directly, under “Is SEO still relevant for generative AI search?”:
“From Google Search’s perspective, optimizing for generative AI search is optimizing for the search experience, and thus still SEO.”
developers.google.com · ai-optimization-guide
Google’s own framing: not a new discipline, still SEO.
Not a variation of SEO. Not a companion discipline sitting next to it. The same thing, by Google’s own framing.
Brightbox Perspective
When a client asks how different AEO or GEO is from what we already do, the honest answer is the same one Google gives. It’s still SEO. We keep doing what we’ve been doing.
Worth knowing if someone approaches you with an AEO or GEO pitch: Google’s guide points readers directly to its own guidance on evaluating third-party SEO advice and services right next to this answer. It’s a useful gut check before paying for anything sold under either label.
04 · The actual advice
What We Tell Clients to Focus On
Setting the myths aside, the guidance we give clients hasn’t moved. It comes down to three things: on-page content that answers the real question a visitor showed up with, off-page signals that a business is real and established, and technical SEO that keeps a site easy to crawl and index, so there’s something for any search system, AI or otherwise, to find in the first place.
Some specific tactics are shifting as everyone learns how AI systems select and cite sources, and that part is genuinely still being worked out, including by us. But the fundamentals a site needs to have in place haven’t changed, and a business already doing SEO well is not behind.
05 · Measuring it
How to Check Whether You Show Up in AI Search
Google also gave site owners a direct way to look at this. On June 3, 2026, its Search Console team announced a dedicated Generative AI performance report, separate from standard search data, showing how often a site’s pages appear inside AI Overviews and AI Mode.
Important
Two things worth knowing before you go looking for it. First, it currently shows impressions only, meaning how often a page appeared, not clicks, click-through rate, or average position. Second, per Google’s own documentation for the report, it’s “rolling out this report to a subset of website owners, allowing for thorough testing before rolling it further.” Not every Search Console account has it yet, and a site also needs enough impressions in AI features before there’s anything to show. If it’s not there for you yet, that’s expected, not something broken.
06 · Common questions
Frequently Asked Questions
Do I need an llms.txt file to show up in Google Search?
No. Google’s guide states it neither helps nor hurts visibility, since Google Search ignores the file entirely.
Will Google penalize my site for having an llms.txt file?
No. The same guide is direct that it causes no harm either way.
Is SEO still relevant now that AI search exists?
Yes. Whether someone finds a business through a traditional search engine or a new AI search feature, Google’s own words are that optimizing for it is still SEO, not a separate practice.
What should I focus on if I’m worried about AI search visibility?
The same SEO fundamentals as always: content that answers real questions, legitimate off-page signals, and a technically sound, crawlable site. That’s what feeds both traditional results and AI features.
Where can I check whether I show up in AI Overviews?
Search Console’s new Generative AI performance report, where it’s available. It shows impressions only for now, and the rollout is still limited.
Where This Leaves You
None of this means AI search doesn’t matter. It clearly does, and how it selects and cites sources is worth watching. It just means the response to it isn’t a new file or a new discipline. It’s the same SEO work, done well.
