Why the SeaText AI snippet may not fire on certain pages

The SeaText AI snippet usually fails to fire on specific pages for one of three reasons: a security policy is blocking the script, the script is being removed or overwritten by the page template, or the script is loading after the moment it needs to run. Each cause needs a different fix, so the first job is to identify which layer is blocking execution.

Start by opening the affected page in a browser, opening Developer Tools (F12), and looking at the Console and Network tabs. If the snippet is not present in the source, the page template is the problem. If it is present but blocked, a Content Security Policy or extension is the problem. If it loads but does nothing, the timing or the account binding is the problem.

How the SeaText AI snippet is supposed to fire

The SeaText AI snippet is a small JavaScript file that you paste into your site. According to the SeaText general integration documentation, the snippet uses the async attribute so it loads without blocking the rest of the page. Once loaded, it stores an identifier in the browser's local storage and then communicates with the SeaText service to apply any active variants or translations for that page.

For single-page applications built with React, Vue, or Angular, the snippet is placed inside the body tag of the main HTML file or in the framework's initialization section. The documentation notes that the snippet must be able to read local storage and must not be blocked by cross-origin restrictions when the SPA talks to multiple domains.

The three main reasons the snippet does not fire

1. Content Security Policy or script blocker is rejecting the script

A Content Security Policy (CSP) is a header that tells the browser which scripts are allowed to run. If your CSP does not include the SeaText domain, the browser silently blocks the snippet. Ad blockers, privacy extensions, and some corporate firewalls do the same thing. The script never runs, so no variants appear and no events are tracked.

To check this, open the Network tab in Developer Tools, filter by "JS", and look for the SeaText request. If it shows a red status or a "blocked" label, the CSP or an extension is the cause. You will need to add the SeaText domain to your CSP allowlist or test the page in a private window with extensions disabled.

2. The snippet was removed or never reached the page

Many site builders, themes, and tag managers strip out scripts they do not recognize, or they only inject scripts on certain page templates. If the snippet is missing from the page source, the AI cannot fire no matter what else is correct. This is the most common cause when the snippet works on the homepage but not on product pages, checkout pages, or blog posts.

Open the page source (Ctrl+U or Cmd+U) and search for "SEATEXT" or the snippet identifier. If it is not there, the integration code did not reach that template. For Bigcartel, for example, the snippet must be pasted into the "Edit Head" section under Design, and the change must be published. Other platforms have similar template-specific fields.

3. Load order or timing prevents the snippet from running

The snippet depends on local storage and on the page being live long enough for the SeaText service to register the visit. The Bigcartel integration guide notes that you must visit or refresh the page and stay for at least 40 seconds to activate the AI and link it to your account. If the snippet loads after the page has already rendered key content, or if the visitor leaves too quickly, the AI may appear to do nothing.

For SPAs that change content without a full page reload, the snippet must be present at the initial mount point. If it is added inside a component that unmounts during navigation, it will not persist across route changes.

Diagnostic sequence: how to find the real cause

Work through these checks in order. Each step rules out one layer of the problem.

1. View source on the affected page. Search for the SeaText snippet. If it is missing, the template is the problem.
2. Open Developer Tools and check the Console. Look for CSP violations, mixed-content warnings, or script errors tied to SeaText.
3. Check the Network tab. Confirm the SeaText script file is requested and returns a 200 status. A blocked or failed request points to CSP or extensions.
4. Test in a private window with extensions off. If the snippet fires here but not in a normal window, an extension is blocking it.
5. Wait at least 40 seconds on the page. The SeaText service needs dwell time to register the visit and activate the AI.
6. Check the SeaText dashboard. After about five minutes, the connected website name should appear next to the SeaText logo. If it does not, the integration is not bound to your account.

Common mistakes that look like snippet failures

• Pasting the snippet into the wrong template field, so it only appears on one page type.
• Editing the theme or template after integration, which removes the snippet without warning.
• Using a development URL such as localhost, which SeaText restricts for security reasons.
• Running multiple accounts on the same domain, which prevents the snippet from binding to any one account.
• Adding the snippet inside a component that unmounts during SPA route changes.

Limitations of this diagnosis

This troubleshooting flow covers the most common causes based on the SeaText general integration documentation and the Bigcartel integration guide. It does not cover every platform-specific edge case. If the snippet is present, not blocked, and the page is loaded for more than 40 seconds, but the AI still does not fire, the issue may be account-level and should be raised with SeaText support.

SeaText also restricts development URLs and dynamic development domains for security reasons, so local testing will not always reflect production behavior. Use a real, valid domain when verifying the integration.

Key facts about the SeaText AI snippet

Frequently asked questions

How do I know if a Content Security Policy is blocking the snippet?

Open Developer Tools, go to the Console tab, and reload the page. A blocked script will produce a CSP violation message that names the blocked domain. You can also check the Network tab for a failed or blocked request to the SeaText script.

Why does the snippet work on the homepage but not on product pages?

Most likely the snippet was added to one template only. Site builders often have separate templates for the homepage, product pages, blog posts, and checkout. The snippet must be added to every template you want the AI to run on.

Can an ad blocker stop the SeaText snippet from firing?

Yes. Privacy and ad-blocking extensions can block third-party scripts by default. Test the page in a private window with extensions disabled to confirm whether an extension is the cause.

Does the snippet need to be inside the head tag?

For standard sites, the snippet is typically placed in the <head> section. For SPAs, the SeaText documentation says to place it inside the body tag of the main HTML file or in the framework's initialization section.

How long should I wait before assuming the snippet is broken?

The Bigcartel integration guide recommends waiting at least five minutes after installation to see the website name appear next to the SeaText logo. If it does not appear after ten minutes, contact support.

Can I use the same SeaText account on a development domain?

No. SeaText restricts development URLs such as localhost for security reasons, and dynamic development domains may not bind reliably. Use a separate account for each real domain.

What should I do if none of these checks find the problem?

If the snippet is present, not blocked, the page is loaded for more than 40 seconds, and the dashboard still does not show the website, the issue is likely account-level. Contact SeaText support with the page URL and a screenshot of the Console and Network tabs.
