Seatext AI Not Working on Product Pages? Here's the Fix

If Seatext AI doesn't work on your product pages, the problem is usually in the setup, not the tool. Check three things first: the JavaScript snippet is installed on the exact page template, the product description is wrapped in the required element with a data- attribute, and the account you are logged into is linked to the same primary URL as your product-page domain. Work through those checks, then inspect the live page with your browser's developer tools. If everything passes and you still see no changes, contact Seatext support with your account URL and a screenshot of the HTML.

This article is a diagnostic guide. It moves from symptoms to likely causes to fixes. It also covers the common mistake that makes Seatext AI look broken on product pages even when the rest of the site works.

Check the basics first

Before you change any code, answer these questions:

• Do you have a Seatext AI account? The script is copied from your account area. Without an account, there is no script to install.
• Is the script installed on the same domain as your product pages? Each Seatext account is linked to a single primary URL. A script from one account will not run reliably on another domain.
• Is the domain a real, stable domain? Development URLs such as localhost are restricted, and dynamic development domains may not work.
• Have you activated at least one agent after installing the script? Seatext AI stays inert until you activate it.

Use this diagnostic sequence

Follow this order. It rules out cheap fixes first.

1. Open one product page in a regular browser window.
2. Use View Page Source or developer tools to confirm the Seatext script appears in the HTML.
3. Look for the data- attribute on the product description element.
4. Check the domain in your address bar against the primary URL for your Seatext account.
5. Log into Seatext and confirm the agents you need are active.
6. Save any template changes, clear your page cache if you have one, and reload the product page.
7. If nothing changes after step 6, contact support.

On Shopify, check theme.liquid and the product template

Shopify has a specific install path. The Seatext integration guide uses these steps:

1. In your Shopify admin, go to Online Store > Themes.
2. Next to your active theme, click the three dots icon and choose Edit code.
3. Open the Layout folder and find the file named theme.liquid.
4. Paste the Seatext JavaScript snippet and save the file.

Saving theme.liquid loads Seatext on your Shopify pages. But product descriptions need one more step. The product description is usually rendered in a file named product.liquid or product-template.liquid. Find the line that outputs the product description and wrap it with the required element that includes the data- attribute Seatext looks for. Save the file, then preview a product page.

To confirm it worked, open the same product page in your browser's developer tools and inspect the HTML source. The product description element should include the data- attribute. If it is missing, the template edit did not save, or you edited the wrong template.

The most common mistake: wrong domain or wrong account

The most common reason Seatext AI doesn't work on product pages is that the page is being viewed on a domain that does not match the Seatext account. Each Seatext account is linked to a single primary URL. When you paste the script on a second domain or on a staging URL, the account may not associate that traffic with your site. The result looks like a product-page bug, but it is an account mismatch.

This mistake happens often in product-page testing because you can have a development copy of your store at a URL like staging.example.com while the live store is at www.example.com. Seatext treats those as different domains. Create a separate account for each domain, and only test on a real domain. Localhost is blocked. Dynamic development domains may also fail because Seatext cannot reliably associate traffic with your account.

Why the agent may be active but nothing changes

Installing the script is not the same as turning on the feature. Seatext says the AI remains inert until activated. After you add the script, go to your Seatext dashboard and activate the agents you want on product pages. If the script is installed but no agent is active, the page will load normally and no copy changes will appear.

On product pages, the relevant agents are usually the ecommerce product copy agent, the translation agent, or the personalization agent. Which agents you need depends on your goal. The key point is that activation is a separate step from installation. Check that step before you dig into template code.

Symptom table: likely causes and fixes

When this advice does not apply

This guide is based on the official Seatext integration instructions, which currently give the most detail for Shopify. If your product pages run on a custom CMS or a different ecommerce platform, the generic script steps still apply: copy the JavaScript snippet from Seatext, paste it into your site's shared layout file, and make sure the product description markup includes the required data- attribute. The exact file names will be different.

This advice will not fix server errors, database issues, checkout failures, or problems caused by another app that rewrites your theme files. If a browser extension blocks third-party scripts, that can also look like a Seatext failure. Test in a normal browser window or an incognito window before assuming the installation is wrong.

Key facts at a glance

Terminology you may see in the docs

• Primary URL: the single domain linked to your Seatext account.
• theme.liquid: Shopify layout file that loads scripts across the theme.
• Product template: the Shopify file that renders product details, often product.liquid or product-template.liquid.
• Data- attribute: a custom HTML attribute that starts with data- and helps Seatext identify product description content.
• Activation: turning on an agent in the Seatext dashboard after installing the script.

FAQ

Why does Seatext AI work on my homepage but not on product pages?

Homepage and product pages often use different template files. The script may be in theme.liquid, but the product description still needs the required data- attribute wrapper in product.liquid or product-template.liquid. If it is missing, Seatext does not know which content to optimize.

Can I test Seatext on localhost?

No. Development URLs such as localhost are restricted for security reasons. Use a real, stable domain for testing.

Do I need a separate Seatext account for my staging site and my live site?

Yes. Each account is linked to a single primary URL. If you use a development domain and a production domain, create separate accounts for each.

I installed the script. Why is nothing changing on my product page?

Check that you activated an agent after installation. Seatext AI stays inert until activated. Then verify the product description markup has the data- attribute.

How do I verify the installation myself?

Open the product page in your browser, use developer tools to view the HTML source, and look for the Seatext script. Then find the product description element and confirm it contains the data- attribute.

What should I tell Seatext support if I still need help?

Send the primary URL of your Seatext account, the exact product-page URL, and a screenshot of the HTML source showing whether the script and data- attribute are present. That lets support compare your account against the page quickly.
