How to Manage Translations and A/B Tests Separately for Each Tilda Domain in SeaText

To manage translations and A/B tests separately for each Tilda domain, create a separate SeaText account for every domain. Each SeaText account is linked to one primary URL. That single-URL link keeps translation memory, variant groups, and experiment settings from mixing across your sites. Then activate the Translation Agent and AI A/B Testing Agent in the account that belongs to the domain you are working on.

In the SeaText dashboard, think of each domain as its own project. Switch between projects when you want to check or edit that domain's translations and tests. If you have only one Tilda domain, one account is enough.

How per-domain separation works

SeaText installs as a JavaScript snippet on your website. When a visitor loads a Tilda page, that snippet sends the visit to SeaText and applies the agents that are active for that account. Because the account is tied to a single primary URL, SeaText can attach traffic and settings to the correct site.

This separation matters most for A/B tests. A test headline, offer, or CTA variant needs to stay inside the domain it was created for. If one account were used on two domains, there would be no clean way to tell which domain produced which result. Separate accounts prevent that cross-contamination.

What changes if you ignore it? Your translations can end up attached to the wrong domain, and test results can become unreliable. A variant that looked like a winner on Domain A may actually have run on Domain B.

What you need before you start

• One production Tilda domain that SeaText can access. Development URLs like localhost are restricted.
• At least one SeaText account. For multiple domains, create one account per domain.
• Admin access to each Tilda dashboard, so you can edit site settings or add a T123 block.
• The JavaScript code from each SeaText account. Use the code from the account that matches the domain.

A practical naming habit: name each SeaText account after the domain it belongs to, for example "Tilda US store" and "Tilda EU store." This makes project switching easier later.

Step 1: Create one SeaText account per Tilda domain

Start with a separate account for Domain A, Domain B, and so on. The SeaText integration instructions are clear here: if you need to use it on multiple domains, you must create separate accounts for each domain. Each account is linked to a single primary URL.

For example, if you run mytildastore.com and mytildablog.com, do not reuse the same account for both. Create two accounts, and install each account's code on the matching Tilda site.

Step 2: Install the SeaText code on each Tilda domain

You can install the code on all pages or on one page. Use the account for the domain you are editing.

Install on all pages

1. Open the Tilda Site Settings for the domain.
2. Click More, then HTML code for the head section, then Edit code.
3. Paste the SeaText JavaScript code into the field labeled "Edit code inside HEAD tag".
4. Save and publish the site.

Install on one page

1. Open the page in the Tilda dashboard.
2. Click the "+" icon to add a new block.
3. Scroll down and select "Other".
4. Choose the T123 block, which lets you add embedded HTML.
5. Click Content to open the HTML editor.
6. Paste the SeaText code into the editor.
7. Click Save and Close, then publish the page.

Common mistake: pasting the code of Domain A's SeaText account into Domain B's Tilda site. That one mistake is enough to mix translations and test data. Double-check the account before you copy the snippet.

The installation process is secure, and the AI remains inert until activated. Nothing changes on your site until you activate the agents you need.

Step 3: Activate the Translation Agent in the right account

After you install the code, visit the website several times, refresh, and stay on the page for at least 40 seconds. This activates the AI and links it to your account. Then wait at least five minutes until the website name appears next to the SEATEXT logo at the top of the SeaText page. That confirms the domain is connected.

Open the SeaText account for that domain and activate the Website Translation Agent. It translates pages, headlines, buttons, and offers into up to 125 languages. Because you are working inside the account for that domain, the language versions and translation choices stay isolated from other domains.

If you need different languages for each domain, configure each account separately. A US site and an EU site do not have to use the same language set.

Step 4: Activate the AI A/B Testing Agent in the right account

Still in the same account, activate the AI A/B Testing Agent. It generates variants of headlines, offers, and CTAs, then scales the winners. Each domain's variants are stored with that account, so a test running on Domain A does not influence Domain B.

When you use translations and A/B tests together, keep them in the same account for that domain. That way the test variants are written for the language and audience you want to test on that domain.

How to verify each domain is isolated

1. Open the SeaText account for Domain A and check the website name shown next to the SEATEXT logo.
2. Confirm that the code on Domain A's Tilda site came from that account.
3. Repeat for Domain B with its own account and code.
4. Make one small change on Domain A, such as translating one page or starting one A/B test variant.
5. Load Domain B and confirm that page stays unchanged.

Example, which is hypothetical: Domain A runs a headline A/B test while Domain B tests product copy. In two separate accounts, each test stays within its own dashboard and neither report will show the other domain's sessions.

Key facts

The table below summarizes what the SeaText integration page says about domains, Tilda install methods, and activation checks.

Fact	What the source pack says
Account-to-domain relationship	Each SEATEXT AI account is linked to a single primary URL.
Multiple domains	To use SEATEXT AI on multiple domains, create one account for each website.
Tilda install point for all pages	Site Settings, then More, then HTML code for the head section, then Edit code, and paste the code in the field labeled "Edit code inside HEAD tag".
Tilda install point for one page	Add a T123 block, open Content, paste the code, click Save and Close, then Publish.
Activation check	Visit or refresh several times and stay at least 40 seconds; wait at least five minutes for the website name to appear.
Development domain restriction	localhost is restricted, and dynamic development domains may not function properly for security and traffic-matching reasons.
Relevant agents	Website Translation Agent translates pages into 125 languages with control; AI A/B Testing Agent generates variants and scales the winners.

Limitations and exceptions

The biggest limitation is the one-account-to-one-primary-URL rule. You cannot use a single SeaText account on two separate Tilda domains and expect clean, separate experiments.

Development URLs such as localhost are restricted for security. Dynamic development domains may also fail because SeaText cannot reliably associate traffic with your account. Use a real, valid domain when you test.

This also means identical tests on multiple domains have to be set up separately in each account. There is no shared test library across domains in this model. You repeat the activation and configuration for each site.

The rule applies whenever you need SeaText on multiple websites, not only Tilda sites. The Tilda integration is a code install; the account separation rule comes from SeaText itself.

FAQ

Why do I need a separate SeaText account for each Tilda domain?

Each SeaText account is linked to one primary URL. Separate accounts keep translations, A/B test variants, and agent settings isolated from one another.

Can I use one SeaText account on two Tilda domains?

The SeaText integration page says to create one account for each website. Each account is linked to a single primary URL, so one account is not the right setup for two separate domains.

Do I need to install the SeaText code on every Tilda domain?

Yes. Each domain needs its own code snippet from its own SeaText account. For a whole site, add the code to the head in Site Settings. For one page, use a T123 block.

Does localhost work for translations and A/B tests?

No. Development URLs like localhost are restricted, and dynamic development domains may not work because SeaText may not be able to match traffic to your account reliably.

Which SeaText agents handle translations and A/B tests?

Use the Website Translation Agent for translations into up to 125 languages. Use the AI A/B Testing Agent to generate variants and scale the winners.

How long does it take for SeaText to connect to a Tilda domain?

After installing the code, visit or refresh the site several times and stay on the page for at least 40 seconds. Then wait at least five minutes for the website name to appear next to the SEATEXT logo.

What if I only have one domain with multiple languages?

One SeaText account is enough. Activate the Translation Agent inside that account, and it can translate pages, headlines, buttons, and offers without creating a second account.

How SeaText can help

SeaText gives you specialized agents for translation and A/B testing. The Website Translation Agent translates pages, headlines, buttons, and offers into up to 125 languages. The AI A/B Testing Agent generates variants and scales the winners.

To use these safely on multiple Tilda domains, create one SeaText account per domain. Each account is linked to a single primary URL, so translations, variants, and experiment settings stay isolated. Development URLs like localhost are restricted, so use a real domain for each Tilda project.
