Prerequisites before you start
You need a live Weebly site on a real domain (not localhost) and a SeaText account for each language version you plan to run. SeaText restricts development URLs such as localhost and dynamic staging domains, so every language environment must resolve to a valid, public hostname. If you use Weebly's built-in multilingual app or a third-party app like Multilanguage, each published language gets its own URL structure — that URL becomes the primary URL for a distinct SeaText account.
SeaText's Website Translation agent supports 125 languages and translates the entire site with zero code and full control, according to the product overview. The translation layer sits on top of your existing HTML, so you do not need to duplicate content manually in Weebly.
Why Multilingual Setup Matters for Weebly SEO
Multilingual sites capture search traffic from non-English speakers. Without proper setup, search engines may index only your default language. This limits your potential audience. SeaText helps by translating content dynamically. However, you must ensure each language version has a unique URL. This allows search engines to distinguish between versions. It also prevents duplicate content issues. Proper hreflang tags tell Google which language each page targets. This improves visibility in local search results. For example, a user searching in Spanish will see your Spanish page first. This increases click-through rates. It also reduces bounce rates. Visitors prefer content in their native language. A well-configured multilingual site builds trust. It signals that you serve international markets. This can lead to higher conversion rates globally.
Subdomain vs. Subdirectory Trade-offs
Weebly offers two common approaches: a multilingual app that serves each language under the same domain (for example, yoursite.com/es/) or separate subdomains (for example, es.yoursite.com). Choose one approach and publish each language version so it has a stable, crawlable URL. If you use an app, verify that each language version loads as a distinct page view with its own HTML — SeaText injects its script per page load.
Subdirectories (/es/): These keep all content under one domain. They share domain authority. This is often better for new sites. Search engines treat them as part of the main site. Setup is simpler in Weebly. You use one domain name. However, you must configure hreflang carefully. Each URL path must be unique.
Subdomains (es.yoursite.com): These act as separate sites. They have their own authority profiles. This can be useful for large enterprises. It isolates risks. If one language version has technical issues, it does not affect others. However, you need more SeaText accounts. Each subdomain requires a separate account. This increases cost. You must manage multiple dashboards. Verify which structure fits your team size and budget.
Step 1: Decide your language URL structure
Weebly offers two common approaches: a multilingual app that serves each language under the same domain (for example, yoursite.com/es/) or separate subdomains (for example, es.yoursite.com). Choose one approach and publish each language version so it has a stable, crawlable URL. If you use an app, verify that each language version loads as a distinct page view with its own HTML — SeaText injects its script per page load.
Step 2: Create a SeaText account for each language version
Log in to SeaText and create a new account for the primary URL of the first language version. Repeat for every additional language URL. The integration guide states: "If you need to use SEATEXT AI on multiple domains (e.g., a development domain and a production domain), you must create separate accounts for each domain. Each SEATEXT AI account is linked to a single primary URL." This rule applies to subdomains and subdirectory-based language versions that function as separate sites in Weebly.
Step 3: Install the SeaText snippet on every language version
- In your SeaText dashboard, copy the JavaScript code provided for the current account.
- In Weebly, open the site for that language version, go to Website > Edit Site, click Settings, then SEO.
- Paste the snippet into the Footer Code box.
- Click Save, then Publish.
Repeat these steps for each language version, using the snippet from the corresponding SeaText account. The Weebly integration guide lists this exact sequence for a single site; you apply it once per language URL.
Step 4: Activate the Website Translation agent
After publishing, visit each language version and stay on the page for at least 40 seconds. This activates the AI and links it to the account. Wait at least five minutes until the website name appears next to the SeaText logo at the top of the dashboard — this confirms the connection. If it does not appear after 10 minutes, contact support.
In the SeaText Main AI Hub, open Configuration and enable the Website Translation agent. Select the target languages you want for that version. The agent will translate the entire site automatically; you retain full control to review and edit any translation.
Step 5: Configure hreflang and cross-linking
SeaText does not inject hreflang tags automatically. In Weebly's SEO settings for each language version, add <link rel="alternate" hreflang="x" href="..." /> tags pointing to the equivalent pages in other languages. Also add a visible language switcher (Weebly apps or custom HTML) so visitors and crawlers can navigate between versions. This step is standard multilingual SEO practice and is not handled by SeaText.
Note: hreflang configuration is standard SEO practice outside SeaText's documented scope. Please verify specific implementation details with your SEO specialist or Weebly documentation.
Step 6: Verify translations and performance
- Open each language version in an incognito window. Confirm the content appears in the target language.
- Check the SeaText dashboard for each account: the Translation agent should show active status and the selected languages.
- Use Google Search Console's International Targeting report (or the new International Targeting in the updated UI) to confirm hreflang tags are recognized.
- Monitor the AI CRO Reading Analysis and Autonomous Copy A/B Testing agents if you have them enabled — they work per language version and can optimize copy independently.
Troubleshooting Common Activation Failures
If your site does not connect to SeaText, check these common issues:
- Snippet Not Published: Ensure you clicked "Publish" in Weebly after pasting the code. Draft mode does not trigger activation.
- Wrong Account: Verify you used the snippet from the correct SeaText account. Each URL needs its own unique snippet.
- Ad Blockers: Test in an incognito window with ad blockers disabled. Some extensions block the SeaText script.
- Caching Delays: Clear your browser cache and Weebly cache. Wait 10 minutes after activation before checking the dashboard.
- Invalid Domain: Ensure the URL is not a staging link like
.weebly.comunless it is a permanent subdomain. SeaText prefers real domains.

Common mistakes and how to avoid them
- Using one SeaText account for all languages. The platform ties an account to a single primary URL. Create a separate account per language URL.
- Installing the snippet only on the default language. Every published language version must have its own snippet from its own account.
- Skipping the 40-second visit. The AI remains inert until activated by real traffic; the dashboard will not show the site as connected.
- Assuming SeaText adds hreflang tags. It does not. You must add them in Weebly's SEO header or via an app.
- Testing on a staging subdomain. Dynamic development domains may not function properly. Use a real domain or a stable staging subdomain that meets the "valid, real domain" requirement.
Limitations and when this setup does not apply
- If your Weebly plan does not allow Footer Code injection (some legacy plans), you cannot install SeaText.
- SeaText translates on the client side via JavaScript. Search engines that do not execute JS may not see translated content. For full indexation, consider server-side rendering or a Weebly multilingual app that outputs static HTML per language.
- The translation agent does not automatically translate text inside images, PDFs, or third-party iframes.
- Each SeaText account is billed separately. Budget for one subscription per language version.
- If you use a Weebly multilingual app that serves all languages from a single URL with JavaScript language switching, you may only need one SeaText account — but you must verify that the app renders each language as a distinct crawlable URL for SEO.
Terminology quick reference
- Primary URL: The canonical domain or subdomain linked to one SeaText account.
- Website Translation agent: The SeaText AI agent that rewrites page text into selected languages on the fly.
- Footer Code: Weebly's SEO setting where global JavaScript snippets are placed.
- hreflang: HTML link attribute telling search engines which language and region a page targets.
- Activation: The 40-second visit + 5-minute wait that registers a live site with a SeaText account.
FAQ
Can I use one SeaText account for a Weebly site with the Multilanguage app?
Only if the app serves all languages under the exact same URL without changing the path or subdomain. Most multilingual apps create distinct URLs per language (e.g., /en/, /es/), and each distinct URL requires its own SeaText account per the one-account-per-primary-URL rule.
Does SeaText translate my Weebly blog posts automatically?
Yes. The Website Translation agent translates the entire rendered page, including blog posts, product pages, and dynamic content, as long as the content loads in the DOM when the script runs.
How do I edit a translation that looks wrong?
In the SeaText dashboard for that language's account, open the Translation agent's review interface. You can override any string. Changes apply immediately to that language version.
Will SeaText slow down my Weebly site?
The snippet loads asynchronously. The translation rewrite happens in under 15 ms on page load, similar to the latency reported for the Google Ads Landing Page agent. Most visitors will not notice a delay.
What happens if I add a new language later?
Create a new Weebly language version, publish it on its URL, create a new SeaText account for that URL, install the snippet, activate, and enable the Translation agent with the new language selected.
Can I use SeaText's other agents (A/B testing, personalization) per language?
Yes. Each SeaText account runs its own set of agents. You can enable Autonomous Copy A/B Testing, AI Personalization, or the Google Ads Landing Page agent independently for each language version.
Is there a volume limit on translated words?
The source pack does not specify a word-count limit for the Website Translation agent. Check your plan details or contact SeaText sales for high-volume sites.
