Key takeaways

• To optimize for large language models (LLMs), make your content easy to crawl, answer specific questions clearly, demonstrate first-hand expertise, and support key claims with reliable sources.
• LLM SEO aims to increase the chances that platforms such as ChatGPT, Gemini, and Google’s AI Overviews mention or cite your brand in their answers.
• Traditional SEO is still important. A technically sound, fast, and crawlable website gives search engines and AI-powered platforms better access to your content.
• Clear, comprehensive content helps AI systems connect your pages with the questions people ask. Cover the topic in a way that addresses the user’s intent, related questions, and relevant context.
• Schema markup can clarify specific page details, while consistent brand information helps search systems connect mentions of your business across different sources. An llms.txt file may provide additional context, but major AI platforms have not confirmed that it improves visibility.
• Original research, first-hand experience, and clearly attributed expertise make your content more useful as a source for AI-generated answers.
• AI search gives ecommerce and D2C brands another way to reach customers as they research products, compare options, and decide what to buy.

Ask ChatGPT for the best brand for a particular need, and it may recommend only a few names. In a 2026 survey of active AI users, 54% had used AI to compare products and 47% had used it to help make a purchase decision. Appearing in these answers can shape which products customers consider.

That shift in product discovery is why LLM SEO exists.

Traditional SEO helps pages rank in search results and earn clicks. LLM SEO extends that work to brand mentions and citations within AI-generated answers.

Performing well in traditional search can help, but it doesn’t guarantee that your brand will appear. This guide explains how LLM SEO works and what ecommerce and D2C brands can do to improve their visibility. It also covers the tools and first steps needed to track progress.

What is LLM SEO?

Also called large language model optimization (LLMO), LLM SEO is the practice of improving content so platforms such as ChatGPT, Gemini, Perplexity, and Google’s AI Overviews can find, understand, and potentially reference it in their answers.

Traditional SEO generally measures visibility through rankings, impressions, clicks, and organic traffic. LLM SEO adds another set of outcomes: citations, brand mentions, and inclusion in AI-generated answers. Because these answers may highlight only a few sources or brands, appearing in them can influence what customers consider.

LLM SEO doesn’t replace traditional search engine optimization. It builds on many of the same fundamentals, including crawlability, clear structure, useful content, first-hand experience, and credible sourcing. The difference is that content must also work as a reliable source for a direct answer, not simply as a page designed to rank for a keyword.

How LLM SEO differs from traditional SEO

The main difference is where visibility appears. Traditional SEO aims to earn prominent positions in search results, while LLM SEO also aims to earn mentions and citations within AI-generated answers.

Some AI search systems explore multiple related searches before generating a response. This process called query fan-out breaks a question into related subtopics and runs several searches to gather supporting information. Google says AI Overviews and AI Mode may use query fan-out to develop more comprehensive answers.

Here’s how the traditional SEO and LLM SEO compare:

The two approaches share the same foundation. Google says its existing SEO best practices remain relevant to AI Overviews and AI Mode, with no additional technical requirements or special schema needed. Pages still need to be accessible, indexable, and useful to readers.

How to improve your visibility in AI answers

There's no single ranking factor that determines which sources appear in AI-generated answers. The strongest approach combines established SEO practices with content that is original, accessible, and easy to use as supporting evidence.

Cover the subject thoroughly

Build a useful collection of related pages instead of forcing every question into one article. Connect those pages with descriptive internal links so readers and search systems can find the relevant information.

Use structured data where appropriate

Add schema that accurately reflects the visible content on the page. Structured data can help search engines understand page details and qualify content for certain search features, although Google does not require special schema for its generative AI results.

Publish original information

Share first-hand experience, proprietary research, customer insights, case studies, or expert analysis that adds something unavailable elsewhere. Unique findings and perspectives give AI platforms a reason to reference your content.

Organize content for easy navigation

Use descriptive headings to separate ideas and help readers and search systems identify the section most relevant to a question. Keep paragraphs focused, and use lists when presenting steps or comparisons.

Keep business and product information accurate

Use consistent names, descriptions, specifications, and other details across your website and official profiles. For ecommerce brands, keep product feeds and Merchant Center information current so search systems receive accurate product data.

Make your content accessible

Ensure important information appears as crawlable text and that relevant search and AI crawlers aren’t blocked unintentionally. A page cannot be selected as a source if the system cannot access or index it.

Back up factual claims

Link important statistics and factual claims to reliable sources. Identify authors and contributors, explain how original research was conducted, and display publication or update dates so readers can evaluate the information.

These practices align with Google’s E-E-A-T framework—experience, expertise, authoritativeness, and trustworthiness—and make it easier for readers and AI systems to evaluate the credibility of your content.

Update content when the information changes

Review time-sensitive facts, product details, links, and recommendations as needed. Simply changing the publication date or making minor edits is unlikely to improve visibility if the information itself is not meaningfully updated.

These steps build on the same technical and content foundations as traditional SEO. Our guide to what an SEO agency does explains the work that supports visibility across traditional and AI-powered search.

Does an llms.txt file improve AI visibility?

An llms.txt file is intended to direct AI systems to a website’s important content. However, major AI platforms have not confirmed using it as a visibility signal, and Google says its search systems ignore the file.

LLM SEO tools worth tracking

Google Analytics can identify visits referred by some AI platforms, but it cannot show every instance in which an AI answer mentions or cites your brand. LLM SEO tools help fill that gap by monitoring selected prompts across platforms and tracking metrics such as brand mentions, citations, visibility, sentiment, and competitor share of voice.

Here are several options for different needs and budgets:

*Prices checked in September 2026. Annual billing may reduce the monthly equivalent.

Most teams can start with one platform and a short list of prompts based on questions customers ask while researching and comparing products. Track the same prompts over time to see how often the brand appears, which sources are cited, and how visibility compares with competitors.

Because AI responses can change between searches, consistent tracking provides a clearer picture of your brand’s visibility over time.

What AI search means for ecommerce and D2C brands

Shoppers are using AI tools to research products, compare options, and create shortlists. When an AI-generated answer mentions only a few brands, inclusion can influence which products a customer considers next.

Improving your chances of being included requires visibility beyond your own website. Pursue relevant media coverage, keep third-party profiles accurate, and make it easy for customers to leave detailed reviews or share user-generated content. These sources can give AI search systems additional context about your brand and products.

That doesn’t mean trying to appear for every possible prompt. Prioritize the recommendation, comparison, and product-related questions most relevant to what you sell. These are the searches where an AI mention is most likely to influence which brands customers consider.

How to start optimizing for LLM SEO this quarter

Begin by establishing where your brand appears today, then use that baseline to guide your work:

1. Choose 10-15 buyer questions: Focus on questions customers ask while researching products, comparing options, and deciding what to buy.
2. Record your current visibility: Check how ChatGPT, Gemini, and Google’s AI features answer those questions. Note brand mentions, cited sources, competitors, and gaps.
3. Review your technical foundation: Confirm that important pages are crawlable, indexable, mobile-friendly, and supported by accurate structured data where appropriate.
4. Evaluate your existing content: Look for incomplete answers, unsupported claims, outdated information, and opportunities to add first-hand experience or original data.
5. Set up ongoing tracking: Use one of the tools above to monitor the same prompts and compare visibility over time.
6. Create content that adds something new: Base new pages on customer insights, original research, case studies, or expert experience, not information already repeated across competing sites.

Together, these steps establish your starting point and show where to focus your efforts. Our SEO services incorporate AI visibility into reporting for traditional rankings, organic traffic, and conversions. This keeps the work connected to your broader search strategy and business goals.
