ChatGPT Sites for Business: Collaboration, Private Sharing, Data, Analytics and Custom Domains

What is ChatGPT Sites?

ChatGPT Sites combines creation, refinement, versioning, hosting and sharing in one ChatGPT workflow. Start by describing the audience, purpose, required behavior and information the Site should use, then review the preview and request focused changes in natural language.

Unlike a one-off code response, a Site is a persistent hosted output that can be reopened, refined, configured and shared. It is useful when a team wants to validate a working experience before investing in a separate deployment pipeline.

Every Sites deployment URL is a production deployment. For a review step, save a version without deploying it and verify the content, links, forms, data behavior and audience before launch.

Five major updates announced by ChatGPT

The official ChatGPT post says users created more than five million Sites in the first three months. The important business signal is not the raw number alone: conversational site building is moving from isolated demos toward repeatable team workflows.

• Build together — invite teammates to edit, save and publish a shared Site.
• Share privately — invite named people to a private Site without making it public.
• Launch faster — the official post says prompt-to-deployment is now about twice as fast.
• Explore your data — ask ChatGPT to inspect a Site database; authorized editors can inspect it too.
• Add a custom domain — connect an apex domain or subdomain you control where the feature is available.

A practical prompt-to-production workflow

• Open Sites and include the word website in your prompt or mention @Sites explicitly.
• Describe the audience, primary outcome, user journey, required content and the main action on each screen.
• State which data must persist, which state is temporary, and whether visitors can upload files.
• Review desktop and mobile behavior, then refine one outcome at a time—clarity, completion rate, navigation or accessibility.
• Save a reviewable version before deployment and record which version received approval.
• Configure the audience, sign-in, domain and environment values before sharing the production URL.

Collaboration roles: owner, editor and viewer

Site collaboration requires a workspace. When available, the owner can invite an active workspace member and promote that person from viewer to editor. Editors can open the Site, make changes, save versions and publish updates after the owner performs the first publish.

Editors can read live database data, so access should be limited to trusted teammates. They cannot change the Site audience, invite or remove people, manage settings or analytics, restore versions, transfer ownership or perform the first publish.

• Owner — controls audience, settings, analytics, ownership and the first publish.
• Editor — edits the Site, saves versions and publishes later updates.
• Viewer — can open and use the Site within the configured audience but cannot edit or publish it.

Private sharing for client reviews and internal tools

Where external invitations are available, set access to Only those invited and add the viewer's email address. The recipient signs in with the invited account. A viewer does not become a workspace member or Site editor.

This is useful for client prototypes, internal dashboards, partner portals, training materials and pre-launch review. Removing one invitation does not override access the same person may still have through a public, workspace or group audience, so review the complete audience configuration.

Durable data, file storage and Sign in with ChatGPT

Sites can use D1 for durable structured records such as requests, progress, scores or user-owned records, and R2 for images, documents, audio, video and other uploads. When files need searchable metadata, use D1 for metadata and R2 for the files.

A public Site can add Sign in with ChatGPT for personalized or user-owned experiences. Sites forwards the authenticated email and may forward a full name to the server. Authorization decisions belong in server-side code, and the optional name should never be treated as an identity boundary.

• Do not add durable storage for disposable interface state such as a dismissed banner.
• Use D1 when visitors reasonably expect their records to persist.
• Use R2 for file workflows and define who can read or modify each asset.
• Explain what identity data the Site receives and how it is used.

Analytics and custom domains

Sites records traffic automatically and reports unique visitors, page views and trends over configurable date ranges and granularities. This is useful for adoption monitoring, but it is not a substitute for ad conversion tracking, CRM attribution or revenue reporting.

A custom domain can connect an apex domain or subdomain you control through DNS records supplied by Sites. Changing the ChatGPT-hosted URL does not alter a custom domain. The current official documentation says custom domains are not available to Enterprise workspaces at launch.

• Sites analytics — understand visits and page views at a high level.
• Pixel, server-side events and CRM — connect campaigns to leads and revenue.
• Custom domain — maintain brand continuity and a trusted destination.
• DNS, SSL and tracking QA — verify the final domain before buying traffic.

Business use cases

Sites can accelerate the experience layer. Workflows that run on a schedule, synchronize multiple systems, route leads, send alerts or require multi-stage approvals still need a clearly designed automation layer.

• Campaign landing page — validate a message, offer and lead form before a larger build.
• Sales calculator — help prospects compare packages or estimate a business outcome.
• Internal request portal — collect briefs, assign ownership, update status and filter work.
• Executive dashboard — consolidate the KPIs leaders need without opening multiple spreadsheets.
• Training microsite — organize lessons, checklists and progress for a team.
• Event registration prototype — validate the flow before integrating a production CRM.
• Interactive content — build a quiz, assessment, planner or product selector.

Turn a fast landing page into a measurable AI ads system

A landing page creates business value only when the team can measure Impression → Click → Lead → Qualified lead → Sale. Built-in traffic analytics does not replace event design, pixels, server-side conversion events, UTM governance, CRM feedback or a decision dashboard.

OG Solution's AI Ads & Conversion System connects campaign structure, landing pages, Pixel and Events API, CRM feedback, reporting and controlled AI analysis so optimization follows customer quality and revenue—not page views alone.

Connect the Site to operational AI automation

The Site can be the intake or dashboard layer while an automation workflow sends leads to a CRM, updates Google Sheets, creates documents, alerts a LINE channel, prioritizes requests and schedules reports. Reliable automation requires explicit triggers, data mapping, approvals, permissions and error handling.

OG Solution builds controlled AI automation for repetitive business operations, from scheduled reporting to multi-tool agents, with logging and human review before material actions.

Pre-publish checklist

• Review all generated copy, images, links, forms and interactions on desktop and mobile.
• Confirm that no secrets, credentials, client records or unlicensed third-party assets are exposed.
• Test audience and sign-in behavior from a viewer account, not only the owner account.
• Keep authorization in server-side code and treat names as optional display data.
• Provide a privacy notice and appropriate consent for collected personal data.
• Save a version before deployment and document the approved release.
• Avoid unsupported uses including payment-card processing, financial transactions and protected health information.
• If the Site will receive paid traffic, install and test conversion tracking before launch.
