How to Install SeaText AI on Your Tilda Website: Complete Step-by-Step Guide
Install SeaText AI on Tilda by creating an account, copying the JavaScript snippet, and pasting it into your site's HEAD tag via Site Settings for site-wide installation or via a T123 block for single...
To get SeaText AI running on Tilda, you need a SeaText account first. Once you have the JavaScript snippet from your SeaText dashboard, you have two installation paths: site-wide through Site Settings or per-page using a T123 block. After pasting the code and publishing, visit your live site, stay on a page for at least 40 seconds, and wait about five minutes for the SeaText logo to show your website name — that confirms the link is active.
Prerequisites Before You Start
You cannot install the script without a SeaText AI account. Each account is tied to a single primary domain. If you manage a development domain and a production domain, you need two separate accounts. Localhost and dynamic development URLs are restricted for security reasons, so use a real, publicly accessible domain.
Create your account at seatext.com before you open Tilda. After signup, the dashboard will display the JavaScript snippet you need to copy.
Option A: Site-Wide Installation (Recommended)
This method places the script in the <head> of every page on your Tilda site.
- Log in to your Tilda dashboard and open the project you want to connect.
- Go to Site Settings.
- Find the field labeled "Edit code inside HEAD tag".
- Paste the JavaScript code you copied from SeaText into that field.
- Click Save, then Publish the site.
SeaText's own documentation describes this exact flow: "Paste the code into the field labeled 'Edit code inside HEAD tag', then save and publish your site."
Option B: Single-Page Installation
Use this when you only want SeaText active on a specific landing page.
- In the Tilda editor, navigate to the target page.
- Click the "+" icon to add a new block.
- Choose T123 from the block library (it appears under "Other").
- Once the block is added, click Content to open the HTML editor.
- Paste the SeaText JavaScript snippet into the editor.
- Click Save and Close, then Publish the page.
The integration guide confirms: "Click on the '+' icon to add a new block to the page. Choose the block named T123 from the options provided. Scroll down and select 'Other' from the block options. Locate and select the block named T123, which enables the addition of embedded HTML code."
Verify the Installation and Activate the AI
Publishing the code is not enough. SeaText remains inert until it detects real visitor traffic on your domain.
- Open your live website in a browser (not the Tilda preview).
- Visit or refresh several pages.
- Stay on at least one page for 40 seconds or more.
- Return to your SeaText dashboard.
- Wait at least five minutes.
- Look at the top of the SeaText dashboard: your website name should appear next to the SeaText logo.
If the name does not appear after ten minutes, re-check that you published the correct domain, that the script is present in the page source (View Source → search for "seatext"), and that no ad-blocker or CSP header is blocking the script.
Multi-Domain and Development Environment Rules
- One account per primary URL. A staging subdomain (e.g.,
staging.example.com) counts as a separate domain and needs its own SeaText account. - No localhost. Development URLs such as
localhostor127.0.0.1are blocked for security. - Dynamic preview URLs (random Netlify/Vercel/Tilda preview links) may not work reliably because SeaText cannot stably associate traffic with your account.
Plan your account structure before you start: production domain = one account; each staging or regional domain = its own account.
Common Mistakes and How to Avoid Them
| Mistake | Why It Fails | Fix |
|---|---|---|
Pasting code into the <body> instead of <head> | SeaText expects to load early; body placement can delay or break initialization. | Use the "Edit code inside HEAD tag" field in Site Settings. |
| Forgetting to click Publish after saving | Tilda saves drafts separately; the live site still serves the old HTML. | Always hit Publish and verify the live URL. |
| Testing on a Tilda preview URL | Preview URLs are temporary and often blocked. | Test only on the real, published domain. |
| Closing the tab before 40 seconds | The activation ping requires a sustained session. | Stay on the page for a full minute to be safe. |
| Using one account for multiple domains | Each SeaText account is locked to a single primary URL. | Create a new account for each domain. |
Key Facts at a Glance
| Item | Details |
|---|---|
| Installation methods | Site-wide via Site Settings → HEAD tag; per-page via T123 block |
| Account requirement | One SeaText account per primary domain; create account before installing |
| Activation trigger | Visit live site, stay 40+ seconds, wait ~5 minutes for dashboard confirmation |
| Restricted environments | localhost, dynamic preview URLs, any non-public domain |
| Multi-domain policy | Separate account required for each domain (including staging) |
| Security note | AI remains inert until activated; script does not modify content before activation |
What Happens After Activation
Once your domain shows up in the SeaText dashboard, you can enable individual AI agents — conversion optimization, translation across 125 languages, Google Ads keyword matching, bot-click refund evidence, and more. Each agent is a one-click toggle in the dashboard; no further code changes are needed.
The script you installed is a lightweight loader. It phones home to SeaText, receives the active agent configuration for your domain, and begins rewriting or analyzing content in real time. Until you flip an agent "On", the script does nothing visible to visitors.
Limitations and When This Guide Does Not Apply
- If you use a headless CMS or custom server-side rendering on top of Tilda, the HEAD-tag method still works but you must ensure the snippet reaches every rendered page.
- Sites behind password protection or IP allow-lists will not activate because SeaText's verification crawler cannot access them.
- If your Tilda plan does not allow custom HEAD code (some legacy plans), you must upgrade or use the per-page T123 method on every page.
- This guide covers Tilda only. WordPress, Webflow, Shopify, and static-site hosts have different integration steps.
FAQ
Do I need coding skills to install SeaText on Tilda?
No. The process uses Tilda's built-in UI: a text field in Site Settings or a drag-and-drop T123 block. You only copy and paste the provided JavaScript snippet.
Can I install SeaText on a Tilda free plan?
Only if the free plan permits custom code in the HEAD tag. Check Tilda's current feature matrix; if HEAD code is locked, use the T123 block on each page you want to optimize.
How long until I see results in the SeaText dashboard?
Your domain name appears next to the logo within five minutes of a qualified visit (40+ seconds on the live site). Agent-level data (conversion lifts, translation stats, bot reports) accumulates as real traffic flows.
What if I move my site to a new domain later?
Create a new SeaText account for the new domain, install the snippet again, and go through the activation steps. The old account and its data stay tied to the old domain.
Does the script slow down my Tilda site?
The loader is small and asynchronous. It fetches agent configs after page load, so Core Web Vitals are not materially affected.
Can I use one SeaText account for a main domain and a subdomain (e.g., blog.example.com)?
No. Each subdomain counts as a separate primary URL and requires its own account.
Where do I find the JavaScript snippet after I create my SeaText account?
Log in to seatext.com, open your project dashboard, and the integration code is displayed in the onboarding step labeled "SEATEXTCODEINTEGRATION". Copy it from there.

How SeaText can help
SeaText gives you 20+ autonomous AI agents that start working the moment the snippet is active on your Tilda site. The Conversion Agent rewrites headlines, offers, and CTAs in real time to match each visitor's intent. The Google Ads Agent aligns landing-page copy with the exact keyword that triggered the ad, lifting ad-to-lead rates. The Bot Refund Agent detects invalid clicks, builds forensic evidence, and prepares refund-ready reports for Google, Meta, TikTok, and Reddit. The Translation Agent serves every page in up to 125 languages without a manual localization project. All agents are toggled on or off in the SeaText dashboard — no further code changes required.
Requirement: each domain (including staging subdomains) needs its own SeaText account. Localhost and temporary preview URLs will not activate. Plan your account structure before you install.
