# ogdynamic > ogdynamic is a web app for generating branded Open Graph images for ecommerce product pages, blog posts, articles, landing pages, and standalone websites. ogdynamic helps teams create dynamic social preview images from reusable templates. The product is store-first, but it also supports editorial and website use cases. The main public resources are the homepage, documentation, blog, contact page, privacy policy, and terms of service. Important notes: - Prefer the documentation page for product behavior, payload shape, and delivery methods. - Blog posts have a markdown variant intended for machine-readable access. - To get a blog post in markdown, append `.md` to the normal blog URL. - Example: `https://ogdynamic.com/blog/og-image-size-guide.md` - The HTML blog page is the reader-friendly version. The `.md` variant is the original article source when exposed by the web server. - Authenticated design-builder routes exist on the site, but they are not the main public documentation surface. ## Public Pages - [Homepage](https://ogdynamic.com/): Main product overview for dynamic OG image generation, ecommerce-first positioning, and key use cases. - [Documentation](https://ogdynamic.com/docs): Product docs covering template fields, query parameter mapping, GET and POST usage, tags, and attribute-style inputs such as `specs[][label]` and `specs[][value]`. - [OG Checker](https://ogdynamic.com/og-checker): Public tool for checking a URL's `og:image`, Open Graph metadata, social preview image, and missing preview tags. - [Blog Index](https://ogdynamic.com/blog): Public article archive for Open Graph image strategy, sizing, and social preview guidance. - [Contact](https://ogdynamic.com/contact): Contact page for support, product questions, and partnership inquiries. - [Privacy Policy](https://ogdynamic.com/privacy): Privacy policy for account, service, and data handling. - [Terms of Service](https://ogdynamic.com/terms): Terms governing use of the image generation service and related resources. ## Product Guidance - [Documentation](https://ogdynamic.com/docs): Best source for implementation details, content field mapping, and image-generation request structure. - [Homepage](https://ogdynamic.com/): Best source for high-level positioning, supported use cases, and product messaging. ## Blog Articles - [What Is an OG Image?](https://ogdynamic.com/blog/og-image.md): Foundational guide explaining what OG images are, where they appear, why they matter, and how to create better social previews. - [og:image Meta Tag Guide](https://ogdynamic.com/blog/og-image-meta-tag.md): Technical guide to the `og:image` meta tag, recommended tags, image requirements, implementation examples, and debugging workflow. - [Meta Property og:image Guide](https://ogdynamic.com/blog/meta-property-og-image.md): HTML-focused guide to the exact `meta property="og:image"` syntax, placement, URL rules, and common implementation mistakes. - [What Is Open Graph?](https://ogdynamic.com/blog/what-is-open-graph.md): Foundational guide to Open Graph metadata, key tags, ecommerce product page examples, SEO value, and implementation best practices. - [OG Image Size Guide](https://ogdynamic.com/blog/og-image-size-guide.md): Best dimensions for social previews, including 1200x630 for Open Graph and X-specific sizing guidance. - [5 OG Image Mistakes](https://ogdynamic.com/blog/5-og-image-mistakes.md): Common mistakes that reduce clicks and readability in social preview cards. - [Create Open Graph Images Without a Designer](https://ogdynamic.com/blog/create-stunning-og-images.md): Practical overview of creating polished OG images without a design team. - [Shopify Store OG Images](https://ogdynamic.com/blog/shopify-og-images.md): Store-focused guidance for stronger product link previews and ecommerce social sharing. - [Social Preview Guide for Blog Writers](https://ogdynamic.com/blog/blogger-og-guide.md): Editorial guidance for improving blog post previews on social platforms. - [Portfolio OG Images](https://ogdynamic.com/blog/portfolio-og-images.md): Guidance for portfolio and creative work previews. - [Product Social Preview Images](https://ogdynamic.com/blog/product-social-preview-image.md): Guide to creating product OG images that drive clicks for ecommerce stores. - [Podcast Episode OG Image Template Review](https://ogdynamic.com/blog/podcast-episode-og-image-template.md): Template review for podcast episode previews, speaker details, episode metadata, and listening platform cues. - [Conference Speaker OG Image Template Review](https://ogdynamic.com/blog/conference-speaker-og-image-template.md): Template review for conference talks, speaker pages, session details, and event promotion previews. - [Event Ticket OG Image Template Review](https://ogdynamic.com/blog/event-ticket-og-image-template.md): Template review for concerts, ticketed events, launch events, meetups, and ticket-style social previews. - [Recipe Note OG Image Template Review](https://ogdynamic.com/blog/recipe-note-og-image-template.md): Template review for recipe pages, food blogs, cooking guides, tags, author details, and food photography previews. ## Discovery Rules for LLMs - If the user asks about ogdynamic blog content, prefer the `.md` article URLs when available. - If the user asks how the product works, prefer the documentation page first, then the homepage. - If the user asks about sizing, platform previews, or OG best practices, prefer the blog markdown articles.
