Jul 06, 2026 05:05 PM - 1 week ago 11304

Google’s John Mueller answered a mobility related to thing a Redditor was utilizing that’s called an llms-author.txt.

The personification who posted the mobility is having a difficult clip being recovered for their sanction because it is the aforesaid arsenic 2 different much celebrated entities, making it much difficult for group to find them and observe their services.

The mobility asked:

“For years this meant a chunk of my “who is this person” awesome was diluted aliases outright incorrect whenever a exemplary aliases a hunt characteristic tried to summarize me.

FIRST STEP

First, an definitive llms-author.txt record abstracted from the main llms.txt, stating occupation title, agency, location and area of believe successful plain sentences alternatively than relying connected schema unsocial to transportation that weight.

SECOND STEP

Second, adding the caller Content-Signal header (ai-train=no, search=yes, ai-input=yes) to robots.txt, mostly retired of curiosity astir whether declaring intent astatine the header level changes thing measurable.”

What they wanted to cognize was if anyone has tally immoderate controlled tests connected Content-Signal headers to spot if they work.

LLMs-author.txt

Apparently the LLMs-author.txt whitethorn not beryllium a existent thing, arsenic successful location is nary charismatic connection for it, overmuch little an existent modular for it.

Content-Signal Header

This is somewhat much confusing. Cloudflare had projected a Content-Signal directive for robots.txt. Cloudflare later utilized the aforesaid Content-Signal syntax arsenic an HTTP consequence header automatically generated successful Markdown for Agents. Markdown for Agents is simply a Cloudflare characteristic that automatically serves a Markdown type of a web page whenever a web customer requests it.

So of the 2 things the Redditor is using, neither of them look to beryllium a portion of an existent proposal.

Google’s Take On LLMs-Author.txt

Google’s John Mueller correctly referred to Cloudflare’s Content-Signal arsenic a robots directive, which is what the connection formally is.

He responded:

“I conjecture a fewer things …

* Google doesn’t usage llms.txt aliases llms-author.txt. I don’t cognize of immoderate different crawler / llm confirming they’re utilizing these (other than SEO tools).

* AFAIK nary of the crawlers / llms usage the “content-signal” robots.txt directives. It was made up by a CDN, afaik it has nary effects whatsoever for immoderate crawler aliases llm. Using it conscionable adds bloat & early attraction to your robots.txt file.

You tin besides adhd different arbitrary things to your robots.txt file, crawlers conscionable usage the directives that they support and disregard the rest.”

The Redditor’s Solution May Not Be Technical SEO

The Redditor is pursuing a method SEO solution to lick a problem that is measurement extracurricular of method SEO. LLMs, chatbots, and hunt engines trust connected signals from the web, including system data. But for this situation, because the web says these different entities beryllium pinch the aforesaid name, the Redditor’s rumor is really pinch the web and not a method SEO rumor to solve. They whitethorn find a satisfactory solution to their problem by becoming amended known connected the web, possibly by being interviewed connected videos, podcasts, and successful web pages. Perhaps they should do much noteworthy things to grow their integer footprint connected the Internet.
