Customizing Interview Slugs

Your interview slug is the last part of the URL that participants see when they click your link. Customizing it makes the link more memorable, more professional, and more trustworthy. Instead of a random identifier, your link can read /i/acme-product-feedback or /i/2024-ux-study.

What Is an Interview Slug?

Every Koji interview has a URL in this format:

https://yourdomain.com/i/your-slug-here

The slug is the your-slug-here portion. When you create a new project, Koji generates a default slug based on your project name. You can change it at any time.

How to Change Your Slug

Slug editing requires the customizable slug entitlement, which is available on paid plans. If your plan includes this entitlement:

1. Open your project from the dashboard.
2. Find your interview link displayed near the top of the project page.
3. Click the edit (pencil) icon next to the slug.
4. Type your new slug.
5. Click Save.

Koji validates the new slug immediately. If the slug is already taken, you will see a 409 Conflict error and need to choose a different one.

Slug Format Rules

Slugs must follow these rules:

• Lowercase letters only — uppercase letters are automatically converted to lowercase
• Numbers are fine — 2024-study works perfectly
• Hyphens for separators — use hyphens instead of spaces or underscores
• No special characters — only a-z, 0-9, and - are permitted (regex: /^[a-z0-9-]+$/)
• Length: Between 3 and 50 characters

Examples of valid slugs:

acme-feedback
product-research-q1
ux-study-2024
customer-interviews

Examples of invalid slugs:

Acme_Feedback      (uppercase and underscores)
my study           (spaces)
research@acme      (special characters)
ab                 (too short — minimum 3 characters)

Best Practices for Memorable Slugs

Keep It Short and Descriptive

The best slugs are short enough to remember but descriptive enough to convey purpose. Aim for two to four words separated by hyphens.

Good: acme-feedback, product-research, onboarding-study Too long: acme-corporation-quarterly-product-feedback-survey-2024 Too vague: study, interview, research

Include Your Brand

If you are sharing the link externally, including your brand name or a recognizable shorthand helps participants feel confident they are clicking a legitimate link.

acme-feedback
myapp-ux-research
widgets-customer-voice

Add Context

If you run multiple studies, add a distinguishing element like the topic, quarter, or audience:

acme-onboarding-q1
acme-pricing-feedback
acme-enterprise-interviews

Think About Sharing

When your link is shared on social media or in a message, the slug is visible to everyone. A clean, professional slug reflects well on your study and your brand.

Links that look like /i/acme-product-feedback inspire more confidence than /i/x7f92k3.

When to Change Your Slug

You can change your slug at any time, but keep these considerations in mind:

• Before sharing: Ideally, set your final slug before you distribute the link. This avoids the need to resend links or update references.
• Active links break: If participants have already received the old link, changing the slug means those links will no longer work. There is no automatic redirect from old slugs to new ones.
• Imported participants: If you have already imported participants via CSV, their unique tracking links include the slug. Changing the slug will break those links.

The safest approach is to finalize your slug before publishing your study and distributing links.

Slug Availability

Slugs are unique globally across all Koji accounts. Two projects anywhere on the platform cannot share the same slug, even if they belong to different users. If you try to use a slug that is already in use by any project, Koji will return a 409 Conflict error and ask you to choose a different one.

If you delete or archive a project, its slug becomes available for reuse.

How the Slug Affects SEO and Open Graph

When someone shares your interview link on social media, the Open Graph preview uses your branding settings — headline, description, and OG image. The slug itself appears in the URL preview, so a descriptive slug like /i/acme-product-feedback looks more clickable than a random string.

Search engines generally do not index interview pages (they require interaction to be useful), so SEO is not a primary concern here. The slug's value is purely in human readability and trust.

Troubleshooting

"Slug is already taken"

Another project on the platform is using this slug. Since slugs are globally unique, this could be a project belonging to any account. Choose a different slug — adding your brand name or a specific qualifier usually resolves conflicts.

"Invalid slug format"

Your slug contains characters that are not allowed or does not meet the length requirements. Use only lowercase letters, numbers, and hyphens, and make sure the slug is between 3 and 50 characters long.

Links stopped working after changing the slug

The old slug is no longer active, and there is no automatic redirect. Update any shared links or email templates to use the new slug. For participants who already received the old link, you will need to resend the updated URL.
