ChatGPT and AI: How to Ensure Your Site is Cited in 2026

The Ongoing Importance of SEO in the Face of AI

SEO, or search engine optimization, has not lost its significance despite the transformations brought about by artificial intelligence. If you've noticed a decline in organic traffic without any apparent changes in your rankings, it doesn't mean that traditional SEO is obsolete. It's crucial not to view AI as a mysterious entity to be ignored. Key elements of SEO, such as backlinks, site authority, performance optimization, and content quality, continue to play an essential role. However, AI processes them differently, which can be both an advantage and a disadvantage.

In some cases, quality content may be cited by AI tools even if your site does not have a high domain authority ranking. However, this also means that users can get answers to their questions directly through the AI platform, without visiting your site. Nevertheless, this presents an opportunity to raise awareness of your brand, even if incoming traffic does not increase directly.

The Impact of AI on Search Engines

A recent study by Semrush, covering over 50,000 websites, reveals that traffic from AI increased by 66% in 2025 compared to the previous year. However, this traffic still represents only a tiny fraction, at 0.15%, of total website visits. This highlights two trends: AI captures a significant share of search engine traffic, but this traffic is not necessarily redirected to sites via platforms like ChatGPT, Perplexity, or Google Gemini.

These AI platforms are becoming both the starting point and the final destination for many users, allowing them to obtain all the necessary information without leaving the application. For websites focused on traditional SEO, this means that AI tools do not prioritize them in the same way. Search engines once valued content-rich sites that demonstrated authority on a topic. AI, on the other hand, favors texts that answer users' questions precisely and quickly.

AI search engines require more targeted optimization than what technical SEO typically provides. In addition to standard files like robots.txt and sitemap, it is suggested to have a dedicated llms.txt file for agents and bots that crawl your site. These adjustments are essential to maintain and improve your site's visibility in AI search results.

Checking Your Visibility on AI Search Engines

To assess your visibility on AI search platforms, several methods are available to you, depending on the time and resources you are willing to invest. A simple method is to use ChatGPT, Perplexity, or Google AI Mode to ask a series of questions that your content should answer. Note which sources are cited and how often. This approach is free and quick.

Tools like the HubSpot AEO Grader offer a fast and free analysis of your presence on AI search engines. If you use Google Analytics, you can filter traffic from sites like chatgpt.com, perplexity.ai, or gemini.google.com to track the evolution of your visibility over time.

To go further, consider investing in paid AEO analytics platforms such as Semrush One or Otterly.AI, with plans starting at $29 per month.

Strategies for Gaining AI Citations

According to a study conducted by Princeton, Georgia Tech, and the Allen Institute for AI, several tactics can increase your chances of being cited by generative AI platforms based on language models. They tested nine strategies on 10,000 search queries, finding improvements of up to 40%.

Ensure that your robots.txt file does not block AI crawlers such as GPTBot, OAI-SearchBot, PerplexityBot, ClaudeBot, and Google-Extended. Many popular content management systems block these crawlers by default, which harms your ranking.

AI models extract specific passages rather than entire pages. Start each new section with a clear opening sentence before adding nuances or context. Citing figures and credible sources enhances the credibility of your content, thereby improving its ranking.

Create a llms.txt file at the root of your site, a low-cost experiment proposed by Jeremy Howard of Answer.AI, although it has not yet been validated by major AI companies. Finally, develop a brand presence beyond your website. LLMs like to extract content from various sources, including YouTube videos and Reddit posts.

Thoughts on Optimizing for AI Search

The Semrush study shows that there is a lot of misinformation regarding AI search and SEO. While sites are losing traffic to AI platforms, referral traffic from these tools does not generate as many clicks as one might think.

However, being cited by AI has its advantages, even if it does not directly lead users to your site. If you have already invested in traditional SEO, you are well-positioned to optimize for AI search using existing tools like Semrush or Ahrefs. While more specialized tools for analysis and visibility exist, they are not necessary for everyone.

It is essential to remember that the fundamental principle of creating useful and informative content remains unchanged. However, AI tools approach the search for answers to user queries differently, which can help you appear in more responses.
