How to Install SeaText on Squarespace Using Code Injection

Yes, Code Injection Works for SeaText on Squarespace

SeaText provides a JavaScript snippet that you can paste directly into Squarespace's Code Injection area. This is the official method documented in SeaText's Squarespace integration guide. The process takes about one minute and requires no custom code development.

Code injection is a built-in Squarespace feature. It lets you add custom code to your site without editing template files. This is ideal for tools like SeaText that need to run on every page. The script loads in the header, so it executes early and works across your entire site.

Why use code injection instead of other methods? It is simple, reversible, and does not require a developer. You can remove the code anytime by deleting it from the injection area. This makes it a low-risk way to add SeaText.

What You Need Before You Start

• A SeaText AI account. If you don't have one, create it first.
• Your SeaText JavaScript code snippet, which appears in your SeaText dashboard after account creation.
• A Squarespace site on version 7.0 or 7.1. Code Injection is available on both, but per-page code injection requires an upgrade to 7.1.
• Access to your Squarespace admin dashboard with permission to edit site settings.

Make sure you have the correct snippet. The code is unique to your account. Do not share it or use another site's code. If you lose it, you can regenerate it from your SeaText dashboard.

Check your Squarespace plan. Some lower-tier plans may restrict access to Developer Tools. If you cannot find the Code Injection option, verify your plan's features. You may need to upgrade.

Step-by-Step Installation

1. Log in to your Squarespace dashboard. Navigate to the website panel for the site you want to modify.
2. Open Settings. Click the three dots icon (⋯) next to your site name and select Settings.
3. Go to Developer Tools. Scroll to the bottom of the Settings page and click Developer Tools.
4. Click Code Injection. This opens the area where you can insert custom code snippets.
5. Paste the SeaText JavaScript code. Place the snippet into the HEADER field. Do not put it in the FOOTER field unless SeaText's instructions specifically say so.
6. Click Save. This preserves your changes.
7. Publish your site. Changes only apply after you publish. If you're working on a draft, publish it to make the script live.

The header field is the correct location. SeaText's integration guide explicitly says to paste the code into the HEADER area. The footer may work, but it is not recommended. The header ensures the script loads before the rest of the page, which is important for SeaText's real-time features.

After pasting, double-check that you copied the entire snippet. A missing character can break the script. If you are unsure, paste it into a text editor first to verify.

Activate and Verify the Connection

After saving and publishing, SeaText needs to link the script to your account. Follow these steps:

1. Visit or refresh your website several times.
2. Stay on your page for at least 40 seconds. This activates the AI and links it to your account.
3. Wait at least five minutes. Then check the top of the SeaText dashboard for your website name next to the SeaText logo.
4. If you see your website name, the connection is successful. If you don't see it after 10 minutes, contact SeaText support immediately.

Why does this take time? SeaText needs to receive traffic from your site to associate it with your account. The 40-second visit ensures the script runs and sends a signal. The five-minute wait allows SeaText to process that signal.

If you do not see your site name, do not panic. Check that your site is published and that you visited it after saving. Also confirm that you used the correct domain. If you have multiple domains, each needs its own SeaText account.

Common Mistakes to Avoid

• Pasting into the wrong field. Use the HEADER field, not FOOTER, unless instructed otherwise.
• Forgetting to publish. Saving alone doesn't apply the code. You must publish your site.
• Using a development domain. SeaText restricts development URLs like localhost for security reasons. Use a valid, real domain.
• Using one account for multiple domains. Each SeaText account is linked to a single primary URL. Create a separate account for each domain.
• Not waiting long enough. The activation process takes at least five minutes. Don't assume it failed before that time.

Another common mistake is pasting the code into the wrong page. Code Injection is site-wide, so you do not need to add it per page. If you are on Squarespace 7.1, you can also use per-page code injection, but for SeaText you want the global header.

Also, avoid using a staging site. If you test on a staging domain, SeaText may not recognize it. Use your production domain for the final installation.

What Happens After Installation

Once the script is active, SeaText's AI remains inert until you activate it. This means your website content stays intact until you choose to enable specific AI agents. After activation, you can configure which agents run on which pages.

SeaText offers multiple agents including a conversion agent, translation agent, bot refund agent, AI SEO agent, and Google Ads landing page agent. You activate the ones you need from the Main AI Hub.

You can also adjust AI parameters. SeaText provides an initial round of automatic translations and variants for testing. You can edit these before going live. This gives you control over what visitors see.

The installation is secure. SeaText does not alter your content until you activate an agent. Even then, you can review changes. This makes it safe to test on a live site.

Limitations and Restrictions

• One domain per account. If you need SeaText on multiple websites, create one account for each website.
• No localhost or dynamic development domains. SeaText may not reliably associate traffic with your account on these domains.
• Code Injection availability. Squarespace 5 does not support per-page code injection. If you're on an older version, you may need to upgrade to Squarespace 7.
• Plan restrictions. Some Squarespace plans may limit Code Injection access. Check your plan's features if you can't find the Developer Tools section.

These restrictions exist for security and reliability. SeaText needs to track traffic accurately. Development domains can cause false signals. Using a real domain ensures proper activation.

If you have a business with multiple sites, plan ahead. Create a separate SeaText account for each domain. This also lets you customize agents per site.

Key Facts at a Glance

Frequently Asked Questions

Do I need a paid SeaText plan to use code injection?

You need a SeaText AI account. The installation process itself doesn't require a paid plan, but activating agents may. Check SeaText's pricing page for details.

Can I use the same SeaText account on my staging and production sites?

No. Each SeaText account is linked to a single primary URL. Create separate accounts for each domain.

What if I don't see my website name in the SeaText dashboard?

Wait at least 10 minutes. If it still doesn't appear, contact SeaText support. This could indicate an installation issue.

Will SeaText change my website content immediately?

No. The AI remains inert until you activate it. Your content stays intact until you choose to enable specific agents.

Can I install SeaText on Squarespace 5?

Code Injection exists in Squarespace 5, but per-page code injection requires Squarespace 7. For SeaText's global script, you can likely use the site-wide Code Injection area.

What happens if I paste the code in the FOOTER instead of the HEADER?

SeaText's instructions specify the HEADER area. Using the FOOTER may prevent the script from loading correctly. Always follow the integration guide.

How do I remove SeaText if I no longer need it?

Go back to Settings > Developer Tools > Code Injection and delete the SeaText snippet. Save and publish your site. The script will stop running.

Can I use code injection on a Squarespace trial site?

Yes, but SeaText may not activate on a trial domain. Use a real domain for testing. Trial sites often have restrictions on custom code.

Does SeaText work with Squarespace's new editing interface?

Yes. Code Injection is available in both the classic and new editor. The steps are the same.

What if my site uses a custom domain?

That is fine. SeaText works with any real domain. Just make sure the domain is active and published.
