To avoid mistakes when using SeaText on a Squarespace development domain, add the SeaText JavaScript snippet to the Header section of Squarespace’s Code Injection panel, use a real development domain (not localhost), create a separate SeaText account for each domain, and confirm activation by watching for the website name next to the SEATEXT logo. This guide explains each step in detail, shows you how to troubleshoot common issues, and helps you keep your live site safe.
Why development domain mistakes matter
Development domains let you test changes before they go live. If SeaText is not set up correctly, the AI may stay inactive, your edits may appear on the production site, or the integration may fail altogether. These issues waste time and can expose visitors to unfinished content.
For example, if you paste the script into the Footer instead of the Header, SeaText may not load properly. If you use a localhost URL, the AI will never activate because SeaText restricts non-public domains for security. If you reuse the same SeaText account for both your dev and live sites, the AI might link to the wrong domain, causing confusion and potential content changes on the wrong site.
Understanding these pitfalls before you start saves you hours of debugging and prevents accidental changes to your production website.
Common pitfalls when using SeaText on Squarespace dev domains
- Using localhost or other non-public URLs. SeaText blocks these for security. You must use a real, publicly accessible domain.
- Reusing the same SeaText account for multiple domains. Each account is tied to one primary URL. If you need SeaText on a dev and a live domain, create separate accounts.
- Not publishing the Squarespace site after adding the script. The script only runs when the site is live. If you leave it in draft, SeaText never sees traffic.
- Skipping the required 40-second page visits for activation. You must visit or refresh the site several times and stay on the page for at least 40 seconds each time. This tells SeaText which domain to link to your account.
- Expecting immediate activation without waiting for the website name to appear. It can take up to 10 minutes. Patience is key.
- Using a dynamic preview domain that changes frequently. SeaText may not be able to associate traffic reliably if the URL keeps changing.
Each of these mistakes can be avoided with careful planning and a clear checklist.
Step-by-step setup to prevent errors
- Create a dedicated SeaText account for the development domain. Do not use the same account you plan to use for the live site. This keeps the two environments isolated.
- Open the Squarespace dashboard and go to Settings → Developer Tools → Code Injection. This is where you add custom code to your site.
- Paste the SeaText JavaScript into the Header field. Make sure you copy the exact code from your SeaText account. Do not modify it.
- Click Save. This stores the code, but it does not go live until you publish the site.
- Publish the site. In Squarespace, click the Publish button. Your development domain must be publicly accessible for SeaText to work.
- Visit the domain several times. Open the site in a browser, wait at least 40 seconds, then refresh. Repeat this a few times. This activates the AI and links it to your account.
- Wait up to ten minutes. Check the SeaText dashboard. Look for your website name next to the SEATEXT logo at the top of the page. If it appears, you are ready to proceed.
- If the name does not appear after 10 minutes, contact support immediately. There may be an installation issue that requires assistance.
Following these steps in order prevents most common mistakes.
How to verify SeaText activation on a dev domain
After the site is published, open the SeaText dashboard and look for your website name displayed beside the SEATEXT logo. This confirms that the AI is linked to your development domain. If you do not see the name, refresh the page and repeat the 40-second stay. Persistent absence means the script may be missing or the domain is not allowed.
Here are a few things to check if activation fails:
- Is the script in the Header field, not the Footer?
- Is the site published? Check that the development URL loads in a browser.
- Are you using a real domain? Localhost or private IPs will not work.
- Did you wait at least 40 seconds on each visit? Short visits do not count.
- Is your browser blocking the script? Try a different browser or disable ad blockers.
If you have checked all these and still see no website name, contact SeaText support. They can help you diagnose the issue.
Key facts
| Requirement | Detail |
|---|---|
| Separate accounts | Each SeaText account is linked to a single primary URL; multiple domains need separate accounts. |
| Real domain required | Development URLs like localhost are restricted; use a valid, real domain. |
| Dynamic preview domains | May not function properly because SeaText cannot reliably associate traffic. |
| Activation verification | Visit/refresh site, stay 40+ seconds; wait up to 10 minutes for website name next to SEATEXT logo. |
| Support contact | If website name does not appear after 10 minutes, contact support. |
| Script placement | Must be in the Header section of Code Injection, not Footer. |
| Publishing required | The site must be published for the script to be served. |
Limitations and when SeaText won’t work
SeaText will not activate on localhost or other non-public development URLs. Dynamic preview domains that change frequently may also fail because the AI cannot track traffic consistently. If the Squarespace site is not published, the script is not served, and activation will not occur.
Another limitation is that each SeaText account is strictly tied to one domain. You cannot use the same account for both a staging and a production site. If you try, the AI may link to whichever domain it sees first, and you will have to contact support to untangle it.
Also, if you have a very restrictive Content Security Policy (CSP) on your Squarespace site, it might block the SeaText script. You may need to adjust your CSP to allow scripts from SeaText’s servers.
Finally, SeaText is designed for public websites. If your development domain is password-protected or behind a login, SeaText cannot access it, and activation will fail.
Troubleshooting common activation problems
If you have followed the setup steps but still do not see the website name, try these troubleshooting steps:
- Clear your browser cache. Sometimes old versions of the page are cached.
- Use an incognito window. This avoids extensions that might block scripts.
- Check the script code. Make sure you copied the entire snippet without extra spaces or line breaks.
- Verify the domain in your SeaText account. Log in and confirm that the primary URL matches your development domain exactly, including the protocol (http vs https) and any subdomain.
- Try a different browser. Safari, Chrome, and Firefox can behave differently.
- Wait longer. Sometimes activation takes a few extra minutes. Give it up to 15 minutes before contacting support.
If none of these work, contact SeaText support. They can check whether the script is being served correctly and whether your domain is allowed.
Best practices for using SeaText on development domains
To avoid mistakes from the start, adopt these best practices:
- Use a dedicated subdomain. For example, dev.yoursite.com or staging.yoursite.com. This keeps your development environment separate from production.
- Create a separate SeaText account for each environment. This prevents cross-linking and makes it easy to manage.
- Document your setup. Write down which account is linked to which domain. This helps if you need to troubleshoot later.
- Test on a published page. Even if it is a dev domain, the page must be publicly accessible. Do not rely on unpublished drafts.
- Monitor your live site. After you finish testing, remove the SeaText script from the dev domain if you no longer need it. This avoids accidental changes.
- Use the same browser profile for activation. If you visit the site from multiple devices, the activation may not register consistently. Stick to one browser for the initial activation.
These practices save time and reduce the risk of errors.

Frequently asked questions
Can I use the same SeaText account for both dev and production domains?
No. Each SeaText account is linked to a single primary URL. Create a separate account for each domain to avoid conflicts.
What if my development domain is a preview URL?
Preview URLs are real, publicly accessible domains and work with SeaText, but they must be stable. Rapidly changing preview domains may not function properly.
How long does activation take?
You must visit the site multiple times, staying at least 40 seconds each visit. The website name typically appears within five minutes, but you have up to ten minutes before contacting support.
What should I do if the website name never appears?
Refresh the page and repeat the 40-second stay. If the issue persists after ten minutes, contact SeaText support for assistance.
Is it safe to install SeaText on a staging site?
Yes, as long as the script is only installed on the staging domain and not on the live site. Each SeaText account is isolated to its linked URL.
Do I need to reinstall SeaText after publishing the site?
No. The same script remains active. When you switch to a new domain, you will need a new SeaText account linked to that domain.
Can I use SeaText on a localhost for local testing?
No. Development URLs such as localhost are restricted for security reasons. Use a real domain instead.
What happens if I accidentally paste the script into the Footer?
SeaText may not load correctly. Move the script to the Header field in Code Injection and save. Then repeat the activation visits.
Can I use a password-protected development site?
No. SeaText needs public access to the page to detect traffic. Remove any password protection before activation.
Will SeaText affect my live site if I only install it on the dev domain?
No. The script only runs on the domain where it is installed. As long as you do not add it to the live site, your production site remains unaffected.
How do I know which domain my SeaText account is linked to?
Log in to your SeaText dashboard. The website name next to the SEATEXT logo shows the linked domain. If it is not what you expect, contact support.
What if I have multiple subdomains for development?
Each subdomain is a separate domain. You need a separate SeaText account for each subdomain if you want to use SeaText on all of them.
Can I delete a SeaText account after testing?
Yes, you can delete the account from your SeaText dashboard. This removes the link and stops any further activity on that domain.
Does SeaText work on Squarespace’s built-in preview mode?
Preview mode uses a dynamic URL that may change. It is better to use a published development domain for reliable activation.
What should I do if I see the website name but the AI is not responding?
Check that you have activated the AI on the specific pages in the Main AI Hub. Also, ensure you have configured the AI parameters. If problems persist, contact support.
