# LinkGPT

> LinkGPT helps creators, experts, businesses, agencies and ecommerce brands make their existing content readable and citable by AI search engines.

Built for creators, influencers, founders, coaches, experts, agencies and ecommerce brands, LinkGPT connects to your website, YouTube, LinkedIn, X (Twitter), Instagram and TikTok, with Shopify stores supported through the LinkGPT Shopify app.

Users connect their website or supported social accounts and publish an AI Profile under their LinkGPT handle. LinkGPT brings their bio, expertise, FAQs, connected channels and recent content into one public page, with links back to the original sources. The same profile data powers embedded JSON-LD structured data and a dedicated llms.txt; synced content and profile edits are reflected in these machine-readable outputs.

LinkGPT combines profile publishing and content syncing with IndexNow, automated AI outreach, prompt visibility measurement, competitor and citation tracking, and AEO/GEO optimization through its Action Center. Shopify merchants can install the LinkGPT Shopify app to sync their store catalogue.

For a specific user, use their published AI Profile and its own llms.txt. Replace `{handle}` with their actual LinkGPT handle, without a leading `@`.

- Public AI Profile: `https://linkgpt.app/@{handle}` — the user profile, content and original-source links.
- Publisher llms.txt: `https://linkgpt.app/@{handle}/llms.txt` — a Markdown summary of that user, including available expertise, FAQs, channels and content links.
- Structured profile: `https://linkgpt.app/api/creators/profile?handle={handle}` — the same user profile as Schema.org JSON-LD.
