7 Mistakes to Avoid When Adding SeaText to Multiple Squarespace Pages

Why the Installation Location Matters More Than You Think

When you add SeaText to multiple Squarespace pages, the biggest mistake is placing the JavaScript snippet in the wrong spot. Squarespace has two different code injection areas: one for the entire site and one for individual pages. If you paste the code into a single page's settings, it only runs on that page. If you want it on every page, you need to use the site-wide Header area.

Another common error is forgetting to publish after saving. The code sits in your dashboard but never goes live until you hit the Publish button. This is especially easy to miss when you're working on several pages at once.

Mistake #1: Using Page-Specific Code Injection Instead of Site-Wide

Squarespace lets you inject code into individual pages through the Page Settings > Advanced > Page Header Code Injection area. This is useful for one-off scripts, but it's a trap when you want SeaText on multiple pages. You'll end up copying and pasting the same snippet over and over, and you'll have to update every page whenever the code changes.

The fix: Go to Settings > Developer Tools > Code Injection and paste the SeaText JavaScript into the Header field. This applies the code to every page on your site automatically. You only need to do this once.

Mistake #2: Forgetting to Create a Separate Account for Each Domain

SeaText links each account to a single primary URL. If you try to use one account on multiple domains—say, a development domain and a production domain—the AI won't associate traffic correctly. The official integration guide is explicit: "Each SEATEXT AI account is linked to a single primary URL."

The fix: Create a separate SeaText account for each website or domain you want to use. This is non-negotiable if you're running a staging site alongside your live site.

Mistake #3: Skipping the Activation Visit

After you paste the code, you need to visit or refresh your website several times and stay on the page for at least 40 seconds. This activates the AI and links it to your account. Many people paste the code, save, and move on—then wonder why nothing happens.

The fix: After saving, open your site in a new tab, wait at least 40 seconds, then refresh a couple of times. Then wait five minutes and check the SeaText dashboard. Your website name should appear next to the SEATEXT logo at the top of the page.

Mistake #4: Not Waiting Long Enough for the Connection to Confirm

Even after the activation visit, the connection isn't instant. The integration guide says to wait at least five minutes before expecting to see your website name in the dashboard. If you don't see it after 10 minutes, you should contact support.

The fix: Build a 10-minute buffer into your workflow. Don't assume the installation failed just because it's not showing up immediately. But do reach out if it's been more than 10 minutes—that could indicate a real problem.

Mistake #5: Using Development or Localhost URLs

SeaText restricts development URLs like localhost for security reasons. Dynamic development domains may not function properly because the AI can't reliably associate traffic with your account. If you're testing on a local environment, the script might load but never connect.

The fix: Use a valid, real domain for testing. If you need a staging environment, use a subdomain of your production domain and create a separate SeaText account for it.

Mistake #6: Not Testing Each Page After Installation

Even with site-wide code injection, some pages might not behave as expected. Template-specific scripts, custom code blocks, or page-level settings can interfere. If you only test your homepage, you might miss issues on product pages, blog posts, or landing pages.

The fix: After installation, visit at least one page from each template type on your site. Check that the SeaText widget loads, that it doesn't break your layout, and that it responds to visitor interactions.

Mistake #7: Ignoring the Activation Step in the Main AI Hub

Installing the code is only half the job. After the connection is confirmed, you still need to go to the Main AI Hub and activate the AI on your preferred pages. The integration guide says: "Proceed to the Main AI Hub to activate the necessary AI on your preferred pages." If you skip this, the code is installed but the AI remains inert.

The fix: After the connection shows up, log into the Main AI Hub, click on Configuration to adjust the AI parameters, and activate the agents you want on each page.

Key Facts at a Glance

What Happens If You Ignore These Mistakes?

If you skip the site-wide injection and use page-specific code, you'll have a maintenance nightmare. Every time SeaText updates its script, you'll need to manually update every page. That's error-prone and time-consuming.

If you use one account for multiple domains, the AI might associate traffic with the wrong site, leading to incorrect analytics and poor optimization. You could also hit security restrictions that prevent the script from working at all.

If you skip the activation visit, the AI stays inert. The code is there, but it's not doing anything. You'll see no changes in conversion rate, no translation, no SEO improvements—just a silent failure.

When Does This Advice Not Apply?

If you only want SeaText on a single page—like a specific landing page for a campaign—then page-specific code injection is actually the right choice. The advice above is specifically for multi-page or site-wide deployment.

If you're using a Squarespace version that doesn't have Code Injection (some older or limited plans), you'll need to use a different method, like adding the code to a Code Block on each page. In that case, the site-wide advice doesn't apply, and you'll need to be extra careful about consistency.

Frequently Asked Questions

Can I use one SeaText account for my staging site and my live site?

No. Each SeaText account is linked to a single primary URL. You need a separate account for each domain, including staging and production.

How long does it take for SeaText to connect after I paste the code?

After the activation visit, wait at least five minutes. If you don't see your website name in the dashboard after 10 minutes, contact support.

What should I do if the code is installed but nothing happens?

First, check that you've completed the activation visit (stay on the page for 40+ seconds). Then check the Main AI Hub to make sure you've activated the AI on your preferred pages. If both are done, contact support.

Do I need to add the code to every page individually?

No. Use the site-wide Code Injection Header area. That applies the code to all pages automatically.

Can I use localhost for testing?

No. Development URLs like localhost are restricted for security reasons. Use a real domain instead.

What if I have multiple websites on different domains?

Create one SeaText account for each website. The integration guide is clear: "To use SEATEXT AI on several websites, create one account for each website."

Do I need to publish my Squarespace site after adding the code?

Yes. The code won't go live until you publish. This is a common oversight when working on multiple pages.
