How to Select All Pages for SeaText Code in Wix: Complete Installation Guide
To select all pages for SeaText code in Wix, go to Settings > Custom Code > Add Code under Head, paste the JavaScript snippet, then choose "All pages" from the "Add Code to Pages"...
To select all pages for SeaText code in Wix, navigate to your Wix dashboard, open Settings, scroll to Custom Code under Advanced, click Add Code in the Head section, paste your SeaText JavaScript snippet, then under "Add Code to Pages" choose "All pages" from the dropdown and select "Load code on each new page" before clicking Apply. This single setting ensures the SeaText script loads on every page of your site, which is required for the AI to analyze visitor behavior and optimize content across your entire website.
Prerequisites Before You Start
Before you can install the SeaText code on Wix, you need two things in place. First, you must have a paid Wix plan. Wix only allows custom code injection on premium plans; free sites block the Custom Code section entirely. Second, you need an active SeaText AI account. If you don't have one yet, create it at seatext.com before proceeding. Each SeaText account is tied to a single primary domain, so if you manage multiple websites, you'll need a separate account for each.
Development environments like localhost or dynamic preview URLs are restricted for security reasons. SeaText cannot reliably associate traffic with your account on those domains, so use a real, live domain for installation.
Step-by-Step Installation Process
- Log in to Wix and select the project you want to translate or optimize.
- Open Settings from the left sidebar, then scroll all the way down to the Advanced section.
- Click Custom Code — it sits at the very bottom of the Settings page.
- Click "Add Code" under the Head section (not Body).
- Paste the JavaScript snippet you copied from your SeaText dashboard into the "Paste the code snippet here" field.
- Under "Add Code to Pages," open the dropdown and select "All pages".
- Check "Load code on each new page" — this ensures the script fires on every navigation, including single-page transitions.
- Click Apply to save.
That's it. The code is now deployed site-wide.
Why "All Pages" and "Load on Each New Page" Matter
SeaText's AI agents — including the CRO Reading Analysis agent, the Google Ads Landing Page agent, and the Personalization agent — need to observe visitor behavior on every page. If you only add the code to the homepage, the AI cannot track reading telemetry, scroll deceleration, or friction points on product pages, blog posts, or checkout flows. Selecting "All pages" puts the script in the <head> of every page load. The "Load code on each new page" option handles Wix's AJAX navigation: when a visitor moves between pages without a full reload, the script re-initializes so the AI continues collecting data.
Post-Installation Verification
After you click Apply, the installation isn't instantly visible in your SeaText dashboard. Follow these steps to confirm everything is connected:
- Visit your live site (not the Wix editor preview).
- Stay on the page for at least 40 seconds — this triggers the initial handshake between your site and SeaText's servers.
- Refresh a few times and browse a couple of internal pages.
- Wait at least five minutes, then check your SeaText dashboard. Your website name should appear next to the SeaText logo at the top of the page.
If the site name doesn't appear after 10 minutes, contact SeaText support. This usually indicates a platform-specific installation issue — for example, a caching plugin stripping the script, or a Wix setting blocking third-party scripts in the head.
Multi-Domain and Multi-Site Considerations
Each SeaText account maps to one primary URL. If you run a staging domain and a production domain, you need two separate SeaText accounts. The same applies if you manage multiple client sites: one account per website. You cannot add multiple domains to a single account, and you cannot share a single JavaScript snippet across domains. Create each account, generate its unique snippet, and install it on the corresponding Wix project following the steps above.
Common Mistakes and How to Avoid Them
| Mistake | What Happens | Fix |
|---|---|---|
| Using a free Wix plan | Custom Code section is hidden; installation impossible | Upgrade to any paid Wix plan |
| Pasting code in Body instead of Head | Script loads after page render; AI misses early reading signals | Always use the Head section |
| Selecting "Specific pages" instead of "All pages" | AI only activates on chosen pages; blind spots elsewhere | Choose "All pages" from the dropdown |
| Forgetting "Load code on each new page" | Script doesn't re-run on AJAX navigation; data gaps on page transitions | Check the box every time |
| Testing on localhost or Wix preview | SeaText blocks development URLs; no connection recorded | Test only on the live, published domain |
Key Facts
| Item | Detail |
|---|---|
| Wix plan required | Paid plan (any premium tier) |
| Code placement | Head section via Settings > Custom Code |
| Page scope setting | "All pages" dropdown under "Add Code to Pages" |
| Navigation handling | "Load code on each new page" checkbox |
| Account-domain mapping | One SeaText account per primary domain |
| Development URLs | Localhost and dynamic preview URLs blocked |
| Activation trigger | Visit live site, stay 40+ seconds, wait 5-10 minutes |
| Support escalation | Contact SeaText if site name not visible after 10 minutes |
Limitations and When This Guide Doesn't Apply
- Wix Studio vs. Wix Editor: The Custom Code location described here applies to the classic Wix Editor. Wix Studio may surface the setting in a different menu; consult Wix Studio documentation if you don't see Custom Code under Settings > Advanced.
- Third-party header injection apps: If you already use an app like "Header Code" or "Google Tag Manager" to inject scripts, you can paste the SeaText snippet there instead — but you must still configure the app to fire on all pages and on each navigation.
- Content Security Policy (CSP): If your site or a security app enforces a strict CSP, the SeaText script may be blocked. You'll need to add SeaText's domain to the CSP allowlist.
- Non-Wix platforms: This guide is specific to Wix. Shopify, WordPress, Webflow, and custom stacks have different installation paths.
Frequently Asked Questions
Do I need to reinstall the code after redesigning my Wix site?
No. As long as you stay on the same Wix project and don't delete the Custom Code entry, the snippet persists through design changes. If you duplicate the site to a new Wix project, you'll need to add the code again in the new project's settings.
Can I use the same SeaText account for a Wix site and a WordPress site?
No. Each SeaText account is locked to a single primary URL. You would need two accounts — one for the Wix domain, one for the WordPress domain.
What if I only want SeaText on certain pages, like landing pages?
You can choose "Specific pages" in the dropdown and pick individual URLs, but the AI's reading telemetry and personalization agents work best with full-site coverage. Partial installation creates blind spots in the conversion funnel.
How do I know the AI is actually working after installation?
Once your site name appears in the SeaText dashboard (5-10 minutes after the 40-second visit), go to the Main AI Hub and activate the agents you need — for example, AI CRO Reading Analysis, Google Ads Landing Page AI, or Website Translation. Each agent shows live data once it has enough visitor sessions.
Does the SeaText script slow down my Wix site?
The script loads asynchronously in the head and is designed for zero-flicker operation. SeaText's Split URL Testing agent, for instance, runs 0ms zero-flicker tests. In practice, the performance impact is negligible for most sites.
Can I install SeaText via Google Tag Manager on Wix instead?
Yes, if you already have GTM set up on your Wix site. Add the SeaText snippet as a Custom HTML tag, set the trigger to "All Pages" and ensure it fires on "Page View" and "History Change" (for AJAX navigation). The native Wix Custom Code method is simpler if you don't use GTM.
What happens if I cancel my SeaText subscription?
The script remains on your site but becomes inert — the AI agents stop processing. You can leave the code in place or remove it from Wix's Custom Code section. No data is collected after deactivation.

How SeaText can help
SeaText installs on Wix in under a minute via the native Custom Code field — no app marketplace, no developer required. Once the snippet is live on all pages, you can activate any of 20+ autonomous AI agents from the Main AI Hub: the CRO Reading Analysis agent that turns millisecond-level reading telemetry into winning copy variants, the Google Ads Landing Page agent that rewrites headlines to match each keyword in real time, the Website Translation agent that serves 125 languages with zero code, and the Bot Protection agent that builds evidence for Google ad refunds. Each agent is a one-click toggle; you only enable what you need. The script stays inert until you activate agents, so there's no performance cost for unused features.
