What is Open Graph for AI?
Open Graph for AI recognises that the Open Graph meta tags originally designed for social media link previews have become a secondary structured data layer that AI engines also consume. When AI retrieval systems fetch a page, they parse Open Graph tags (og:title, og:description, og:type, og:image, og:url) alongside the page's visible content and Schema Markup to build a complete understanding of what the page is about.
This matters for AEO because Open Graph tags often contain the most concise, editorially curated description of a page's content. When a brand writes an og:description, they are crafting a summary specifically designed to represent the page accurately in a compact format — exactly the kind of signal AI engines value when deciding how to describe or cite a source.
The practical implications extend beyond basic metadata. For AI engines that retrieve and process web pages in real time (Perplexity, ChatGPT with browsing, AI Overviews), Open Graph tags serve as a quick-reference layer. If the og:title clearly describes the page topic and the og:description provides a concise summary, the AI retrieval system can more quickly determine relevance and extract the right framing for its response.
Open Graph for AI also includes the og:type property, which helps AI systems categorise content. An og:type of "article" signals editorial content; "product" signals commercial content; "website" signals a general landing page. These type signals complement Schema.org markup in helping AI engines understand the content's role and context.
The og:image tag, while primarily visual, can influence AI processing in engines that use multimodal models. As AI engines increasingly process both text and images, having a relevant, descriptive og:image can contribute to the AI system's understanding of the page topic.
Brands should audit their Open Graph tags with AEO in mind. Common issues include: generic og:descriptions that don't capture the page's unique value, missing og:type declarations, og:titles that differ significantly from the page's H1 (creating conflicting signals), and placeholder images that provide no meaningful context. Each Open Graph tag should be crafted as if it were the brand's elevator pitch for that specific page — because in the AI retrieval context, it often functions as exactly that.
Why it matters
Open Graph tags provide AI retrieval systems with a curated, concise summary of each page. When these tags are well-crafted, they help AI engines quickly understand page relevance and accurately summarise your content. Poorly written or missing Open Graph tags represent a missed opportunity to influence how AI engines frame your content in their responses.
Real-world examples
- 1
Rewriting generic og:descriptions across 50 product pages to include specific product claims and differentiators, improving how Perplexity summarises each page when citing it
- 2
Adding og:type="article" to blog posts and og:type="product" to product pages, helping AI engines correctly categorise content type during retrieval
- 3
Aligning og:title with the page H1 and og:description with the first answer-first paragraph, creating consistent signals for AI extraction

Structured Data for AI
technicalStructured Data for AI refers to the use of schema markup (JSON-LD, microdata) and AI-specific files (llms.txt, llm-profile.json) to provide machine-readable context about your content, products, and brand to both search engines and AI engines.
Schema Markup
technicalSchema Markup is a structured data vocabulary from Schema.org that provides machine-readable annotations about web content. In the AEO context, it helps AI engines understand the type, meaning, and relationships of your content, increasing the likelihood of accurate extraction and citation.
Content Extraction
technicalContent Extraction is the process by which AI engines identify, isolate, and capture the most relevant and citable information from a web page. It determines which specific claims, facts, and statements from your content end up in AI-generated responses.
Machine Parsability
technicalMachine Parsability is the degree to which a web page's content can be accurately read, structured, and understood by automated systems including AI crawlers and language models. High machine parsability means AI engines can reliably extract meaning, context, and citable claims from your content.
Technical AEO
technicalTechnical AEO encompasses the infrastructure and technical configurations that help AI engines discover, crawl, parse, and cite your content. It includes AI-specific crawl policies, structured data implementation, llms.txt files, site architecture optimisation, and content formatting for AI consumption.
