1.10 – Linking A Domain To Public GPTs Lesson

Lesson Overview

When you share a GPT publicly using a link, ChatGPT defaults to showing your first and last name from your billing profile. For entrepreneurs and businesses, this is not ideal—especially when the goal is to maintain a consistent brand presence and keep personal information private.

This lesson walks through linking your public GPTs to a domain name you own. This means anyone clicking on your GPT’s public link will see your domain as verification and, if desired, be directed to your website. You do not need to have an active website for this to work—ownership of a domain is enough. However, using an active business website maximizes credibility and offers an immediate destination for interested users.

This is especially useful for anyone wanting their GPTs to serve as outreach or sales tools. For example, a consulting firm could share custom GPTs to help prospects and clients, but keep the branded website front and center. The skill is relevant whether you’re just launching your first GPT, distributing tools for lead generation, or controlling how your information is represented when GPTs are shared to wider audiences.

Who This Is For

This content is designed for anyone looking to publicly share custom GPTs while keeping a professional presence.

• Entrepreneurs building business or marketing tools with GPTs
• Small business owners wanting GPTs to reflect their brand
• Consultants or agencies sharing custom AI solutions
• Content creators interested in driving web traffic
• Anyone concerned about displaying personal data when sharing GPT links
• Professionals managing multiple brands who need clarity on domain limitations

Where This Fits in a Workflow

You’ll use these steps once you’ve already created your custom GPT and are preparing to make it public or share it widely. Linking a domain is critical when you want your GPT to serve as a branded digital asset. For instance, after designing a custom sales assistant GPT, linking your business’s website means all shared links reinforce your brand and let visitors discover more about your services. Consultants rolling out AI tools to prospective clients can also direct all traffic to a lead capture or info page. It’s an essential step for anyone moving from private experimentation to public or client-facing AI deployment.

Technical & Workflow Benefits

Sharing GPTs without a domain exposes your personal name from billing info, which can appear unprofessional and raise privacy concerns. By linking a domain, you create a controlled, branded experience—anyone accessing your GPT sees your company or brand, not your personal details. The traditional way required sharing links tied to private information or using clunky workarounds. With domain linking, updates are handled in your DNS provider’s dashboard with a simple TXT record, often completing in seconds. This saves you time and eliminates the need to explain links or worry about unintended exposure. In real-world use, business owners routinely see higher engagement and more leads by directing GPT traffic to their own site, and customers are more likely to trust tools connected to a domain versus those showing an unknown name.

Practice Exercise

Practice connecting a custom GPT to a domain you control:

1. Log into your domain provider account (like GoDaddy) and find the DNS management area for a domain you own.
2. Follow along with the video to obtain the verification TXT record from ChatGPT and add it as instructed to your domain’s DNS records.
3. After saving, return to ChatGPT and check if your domain is verified. Test how your public GPT now appears with your domain information.

Reflection: Compare how the public details and sharing experience look before and after linking your domain. How does this change your confidence in sharing your GPT for business or branding purposes?
