Generative Engine Optimization (GEO) or “LLM seeding” is the practice of publishing content in the formats and places LLMs are most likely to scrape, summarize, and cite. LLM seeding includes:

  • What to publish so LLMs actually cite you
  • Where to seed your content for maximum pickup
  • And how to track whether your brand is showing up

LLM vs. SE

According to a Semrush study AI search traffic will surpass traditional search by the end of 2027.

AspectLLMs (ChatGPT, Claude, etc.)Search Engines (Google, Bing, etc.)
How they answer questionsGenerate direct answers by synthesizing knowledge from training dataReturn ranked links to web pages based on keywords and relevance
Source of informationTrained on snapshots of web content (and sometimes licensed datasets)Crawl the live web continuously
CitationsMay include sources (e.g. ChatGPT with web access), but often without deep linkingProvide direct links to source websites
Up-to-datenessMay be outdated (depends on last training or retrieval capability)Near real-time indexing (updated frequently)
InteractivityConversational, can refine or continue context-aware discussionsOne-shot queries with static results
Bias toward content typesPrefers well-written, generalizable, structured content seen during trainingRanks content based on SEO, backlinks, page authority
Visibility requirementsNeeds content to be public, high-quality, and referenced before trainingIndexes any crawlable page, regardless of popularity
PersonalizationPersonalized in some tools (e.g. ChatGPT memory), not by search history yetHighly personalized by user history, location, preferences
Interaction granularityCan summarize, rephrase, explain, and code – beyond just pointing to dataMostly lists URLs/snippets with minimal interpretation
Use casesLearning, summarizing, code writing, brainstorming, complex reasoningFinding exact websites, news, shopping, fast fact-checking
Content lifespan in modelMay persist for months or years in training snapshotsCan update rankings/content visibility within hours to days
User intent targetingUnderstands semantic intent, not just keywordsPrimarily matches keywords and metadata

LLM Preferences & Tools

  • LLMS finds results based on meaning rather than exact keywords
  • LLMs give weight to content mentioned or linked by well-established sources.
  • LLMs are more likely to find and understand content when it’s structured.
  • LLMs learn from publicly accessible question-answer pairs and guides.
  • LLMs can also pull from video transcripts and descriptions.

Fun fact: According to a Semrush study, almost 90% of ChatGPT citations come from search engine positions 21+.

Tools that can be used to train or impact LLMs:

ToolWhat It IsUsed ByWhat It DoesDoes It Affect LLM Training?
LLMS.txtA proposed standard file (like robots.txt)AI crawlers (e.g. OpenAI, Anthropic, etc.)Tells AI bots which pages can be used for training or retrievalYes, if respected by the crawler
robots.txtStandard web control fileSearch engines & AI botsAllows/disallows crawling of pages✅ Affects both SEO and LLM access
Knowledge Graph (KG) (similar to schema.org in MkDocs)Structured metadata embedded in web pagesGoogle, Bing, sometimes LLMsHelps machines understand context (e.g. that a page is about a software tool)⚠️ Not always used directly in LLM training, but useful for context and SEO
Open Graph / Twitter CardsSocial metadata for sharing previewsFacebook, Twitter/X, some AI scrapersHelps format link previews❌ No direct impact on LLM training
SitemapsList of all URLs on your siteCrawlers, search enginesHelps bots find your pages✅ Indirectly useful to LLMs if they crawl
API docs with OpenAPI / SwaggerStructured API definitionsDev tools, LLM code generatorsHelps with tool integrations & understanding your API✅ Can be used in some LLMs (e.g. tool use, code generation)

TODOs

Optimize for citations instead of clicks:

  • Make sure your website and documentation are crawlable (check robots.txt and meta tags).
  • Include AI-friendly content like:
    • detailed technical guides and tutorials
    • FAQs (refer to common pre-sales tickets)
    • comparison posts (compare products to competitors, for our own products use “best of” lists like “best for Alteryx users”, “best all-in-one solution”, etc.)
    • real use cases
    •  come up with unique takes on something in your industry.
  • Use AI-friendly formatting like:
    • bullet points
    • clear headings
    • short paragraphs (chunks)
    • short, declarative lines
    • summary boxes
  • Use blog posts or pages with headlines like:
    • “How to use [Your Product] for [X Problem]”
    • “[Your Product] vs. [Competitor]”
    • “10 Tips for Getting the Most from [Your Product]”
  • Get referenced by other reputable sources, e.g.:
    • ask partners to link to our website
    • ask users or tech bloggers to review our tool or write tutorials referencing it.
    • Submit guest posts to relevant publications and social media with backlinks to the docs or site
    • appear on websites like Product Hunt, AlternativeTo
  • Use schema.org metadata (e.g., SoftwareApplication for your product, Article for blog posts).
  • In YouTube videos, use sections and descriptions that include:
    • who you are and why you’re qualified to cover the topic
    • state what the video covers early on
    • link to related posts or supporting content
  • Make sure visuals like images include:
    • alt text
    • full-sentence captions that explain what’s pictured and why it matters
    • reference images in the text (“As illustrated in the following screenshot…”)
    • use descriptive file names (“xtract-universal-designer-main-menu.jpg”)
  • Publish content in places LLMs look for information like:
    • Medium
    • LinkedIn articles
    • industry sources (magazines)
    • roundups (“best of,” “top tools,” and “expert tips” formats)
    • user-generated content hubs like Quora, gitHub discussions and niche / specialized forums (LLMs cite Reddit more than any other source, according to Semrush)

Example

Content:

  • Item name
  • Quick summary
  • Key features or standout capabilities
  • Pros and cons
  • Pricing

How to Test Results

Run manual prompts across different tools like ChatGPT, Claude, Perplexity, and Gemini. Use a private or incognito browser to avoid skewed results from past queries or personalization. Search the way your audience would with clear search intent.

A sign that your LLM presence increases is an increase in impressions and direct traffic while clicks decrease.
