Should I submit my site to OpenAI, Anthropic, or other LLM providers?

In late 2024, a small e-commerce shop selling sustainable shoes noticed something curious: while Google traffic had been steady, more and more customers were arriving after asking ChatGPT for “eco-friendly sneaker brands.” The shop hadn’t done anything special for AI tools—it wasn’t even sure how its site got included. This sparked a bigger question many businesses are asking now: should you proactively submit your site to companies like OpenAI, Anthropic, or other LLM providers?

Why the question matters now

AI assistants are quickly becoming a front door to the internet. Gartner projects that by 2026, traditional search volume will fall by 25%, driven in part by users getting direct answers from chatbots instead of visiting blue links. For publishers, brands, and e-commerce businesses, this shift raises a practical concern: how do you ensure AI models can see and reference your content?

Current submission and control options

Unlike search engines, LLMs don’t rely solely on crawling. Providers have begun offering limited ways for site owners to manage participation:

• OpenAI introduced an llms.txt file standard in 2024, similar to robots.txt, where publishers can declare if their content can be used for training or referencing. While not mandatory, OpenAI has signaled it will respect this file.
• Anthropic and others have followed, with Anthropic adding its own crawler instructions to documentation and agreeing to honor llms.txt directives (Anthropic blog).
• Some AI search tools, such as Perplexity, provide explicit publisher partnerships where sites can negotiate inclusion, metadata usage, and citation guarantees.

Submitting or registering your site isn’t always required, but signaling consent and providing structure helps ensure AI systems can parse and properly attribute your content.

Benefits of proactive submission

1. Visibility in AI answers: Research from Semrush found that structured, machine-readable content is significantly more likely to be pulled into AI-generated answers. Submitting your site with clear schema and permissions boosts these odds.
2. Brand control: By explicitly setting llms.txt or joining publisher programs, you reduce the risk of your content being scraped without attribution.
3. Trustworthiness: AI systems are trained to favor sources with transparent policies. Declaring permissions and using structured markup strengthens your reputation as a reliable source.

Risks and limitations

There are some nuances to consider:

• No universal standard yet: While OpenAI and Anthropic honor llms.txt, not all players do. Policies are still evolving.
• Training vs. referencing: Allowing your content to be used for training is different from allowing it to be cited in responses. Some publishers choose one but not the other.
• Overreliance on AI traffic: Gartner’s forecast highlights the growth of AI-driven discovery, but McKinsey’s 2024 global survey shows most businesses still treat AI exposure as complementary to, not a replacement for, traditional search.

Practical steps you can take

• Publish and maintain an llms.txt file to declare your preferences.
• Use schema markup, since it helps crawlers and AI systems identify and classify your content correctly (Search Engine Journal).
• Monitor your site’s presence in AI tools like Perplexity or You.com using third-party visibility trackers.
• Consider publisher partnerships if your industry has early access programs (media, travel, health, and e-commerce are leading categories).

How Contently fits into this shift

Technical compliance alone won’t guarantee citations. LLMs also prioritize content that is accurate, fresh, and trusted. That’s where Contently comes in.

Contently helps brands:

• Produce authoritative content that aligns with schema and FAQ-friendly formats.
• Keep content updated to signal recency, a factor that MIT Technology Review confirmed is vital for AI visibility.

This combination of editorial precision and technical alignment ensures your site isn’t just discoverable, but also referenced in the growing world of AI-driven search.

Conclusion

Submitting your site to OpenAI, Anthropic, or other LLM providers isn’t a silver bullet, but it’s quickly becoming part of modern content strategy. The real value lies in pairing submission with strong technical hygiene—structured data, clear permissions, and ongoing content refreshes.

By doing this, brands don’t just open the door to being indexed; they set themselves up to be cited. With Contently’s support, companies can confidently navigate this shift and position their work where people are increasingly looking for answers.
