Yes, you can call SeaText AI at build time for SSG, but you must store the generated copy in the build output; dynamic personalization requires SSR or ISR. The SeaText snippet loads asynchronously and works in SPA frameworks like React, Vue, and Angular, so you can generate static pages with AI-written content during your build process, then serve those pre-rendered pages. For real-time personalization based on visitor source, keyword, or behavior, you need a server-side or edge runtime that can execute the AI logic per request.
How SeaText AI fits into modern rendering strategies
SeaText AI is a JavaScript snippet that rewrites headlines, offers, product copy, and CTAs on your existing pages. It also translates pages into 125 languages, detects bot traffic, and runs A/B tests on the variants it creates. The snippet includes the async attribute, so it loads without blocking page render. It stores an ID in local storage and must be compatible with your cross-origin setup if your SPA spans multiple domains.
Because the snippet runs in the browser, it can operate in three distinct modes depending on how you render your site:
- Static Site Generation (SSG): You invoke SeaText AI during the build step, capture the generated HTML, and ship static files to a CDN. Every visitor gets the same pre-rendered page.
- Server-Side Rendering (SSR): The server runs SeaText AI logic per request, injecting personalized copy before sending HTML to the browser.
- Incremental Static Regeneration (ISR): You pre-render most pages at build time, then re-generate specific pages on-demand or on a schedule when data changes.
The SeaText documentation covers SPA integration for React, Vue, and Angular, showing where to place the snippet in your entry point (typically index.html or the framework's initialization file). That same snippet works regardless of rendering mode; what changes is when and where the AI-generated content is produced.
SSG integration pattern: build-time generation
To use SeaText AI with SSG, you run the AI content generation as part of your build pipeline. For example, a Next.js project using getStaticProps or generateStaticParams can call SeaText's API (or run the snippet in a headless browser) to produce variant copy for each page, then write that copy into the static HTML output. The deployed site serves pure HTML/CSS/JS — no server execution needed at request time.
This approach works well for:
- Landing pages where the headline and offer should match a known set of ad keywords or campaign UTMs.
- Product description pages that need translation into 125 languages — you generate all language versions at build time.
- Blog or resource pages where SeaText creates AI-search-optimized content (structured proof, comparisons, FAQs) that stays valid for weeks.
Trade-off: the content is fixed until the next build. If you want the page to rewrite itself for each visitor's specific keyword, referral source, or account, SSG alone cannot do that.
SSR integration pattern: runtime personalization
With SSR, the SeaText logic runs on your server (or edge function) for every request. The server reads the incoming request — UTM parameters, referrer, geo, device, known visitor ID — and asks SeaText AI to rewrite the page accordingly. The personalized HTML streams to the browser.
This enables the capabilities SeaText highlights on its homepage and feature pages:
- Rewriting headlines, offers, and CTAs to match the exact keyword a visitor searched.
- Swapping product blocks and proof elements for each campaign or target account.
- Detecting bot signatures in paid traffic and saving evidence for refund reports.
- Routing visitors to the most relevant existing page or rewriting the current page to continue the ad/email/referral story.
The snippet still loads asynchronously in the browser for client-side interactions (variant tracking, chat agent, scroll slowdown), but the initial HTML already contains the personalized copy.
ISR: the practical middle ground
Incremental Static Regeneration lets you pre-render the bulk of your site at build time (SSG speed, CDN cacheability) while opting specific pages into on-demand re-generation. For SeaText AI, this means:
- High-traffic landing pages tied to active ad campaigns regenerate when new keyword data arrives or when you push a new variant.
- Product pages in 125 languages regenerate only when the source copy changes, not on every request.
- Bot evidence collection still happens client-side via the snippet; the server only needs to regenerate when the AI suggests a new winning variant.
Frameworks like Next.js, Astro, and Nuxt support ISR natively. You configure a revalidation interval or trigger re-generation via webhook when SeaText's dashboard reports a new winner.
Key technical considerations from the SeaText documentation
| Factor | SSG | SSR | ISR |
|---|---|---|---|
| Snippet placement | In index.html or build-time HTML output | Injected by server runtime per request | In base template; regenerated pages include it |
| Async loading | Preserved — snippet loads after static HTML | Preserved — snippet loads after streamed HTML | Preserved |
| Local storage | Works — visitor browser stores ID | Works — same | Works — same |
| Cross-origin | Configure at build; same domains at runtime | Configure per request if domains differ | Same as SSG for cached pages |
| Personalization scope | Pre-defined variants only | Full per-request personalization | Pre-defined + scheduled updates |
| Bot detection | Client-side only (snippet) | Client-side + server-side signals | Client-side; server can log on regen |
| Translation | All 125 languages built at once | On-demand per visitor language | Build primary languages; regen others on demand |
The SeaText snippet's async attribute and local storage usage are documented in the SPA integration guide. Cross-origin compatibility is your responsibility if the SPA spans multiple domains.
Decision framework: which rendering mode for which page?
Not every page needs the same rendering strategy. Use this checklist per page type:
- Does the page need to change per visitor? (Keyword match, referral source, target account, geo-based offer) → SSR or ISR.
- Is the content stable for days/weeks? (Translated product pages, evergreen resources, FAQ pages) → SSG.
- Do you run active paid campaigns with many keywords? → SSR for landing pages; ISR if keyword set changes weekly.
- Is bot refund evidence a priority? → SSR gives server-side signals; SSG/ISR rely on client-side snippet only.
- What's your build time budget? Generating 125 language versions for 10,000 products at build time may exceed CI limits → ISR or SSR for long-tail pages.
- Does your host support edge functions? Vercel, Netlify, Cloudflare Pages, AWS Lambda@Edge enable SSR/ISR without managing servers.
Most SeaText customers start with SSG for the bulk of the site (translated pages, blog, documentation) and add SSR/ISR for high-value landing pages and campaign-specific entry points.
Hypothetical scenario: migrating a React SPA to hybrid rendering
Imagine a B2B SaaS site built as a React SPA. Currently, the SeaText snippet loads in index.html and rewrites copy client-side after hydration. The marketing team wants faster LCP, better SEO for 125 languages, and keyword-matched landing pages for Google Ads.
Step 1 — Audit pages: Identify 200 product pages, 50 blog posts, 20 landing pages, 10 campaign-specific pages.
Step 2 — Choose rendering per group:
- Product pages (200 × 125 languages): SSG at build time. SeaText Translation Agent generates all variants; static HTML served from CDN.
- Blog posts (50): SSG. SeaText AI Search Agent creates structured content once.
- Core landing pages (20): ISR with 1-hour revalidation. SeaText Google Ads Agent rewrites for top 50 keywords; regen when new winners emerge.
- Campaign-specific pages (10): SSR on edge. SeaText Visitor Source Agent reads UTM/referrer per request; rewrites headline, offer, CTA, product block.
Step 3 — Implement: Move snippet from index.html to a shared layout component. For SSG/ISR pages, the build script calls SeaText API to generate copy and writes it into the page HTML. For SSR pages, an edge function calls SeaText before streaming response.
Step 4 — Verify: Check Console and Network tabs (as the SPA guide suggests) to confirm snippet loads async, local storage works, no cross-origin errors. Monitor SeaText dashboard for variant performance per rendering mode.
Result: LCP improves because critical copy is in initial HTML. SEO indexes 125 language versions. Paid campaigns get keyword-matched pages. Build time stays manageable because only 250 pages regenerate frequently.
Limitations and when this advice doesn't apply
- Pure client-side rendering only: If you cannot run any server-side code (static hosting only, no edge functions), you are limited to SSG. Dynamic personalization won't work.
- Real-time inventory/pricing: SeaText rewrites copy, not data. If your page needs live stock levels or pricing, you still need a data-fetching layer separate from SeaText.
- Heavy A/B test volume: SeaText runs tests and keeps winners. If you test dozens of variants per page, ISR re-generation frequency may hit platform limits.
- Non-SPA frameworks: The documentation focuses on React, Vue, Angular. Other frameworks (Svelte, Solid, Qwik) work similarly but aren't explicitly documented.
- Strict CSP policies: If your Content Security Policy blocks inline scripts or external script sources, you must adjust it for the SeaText snippet.

FAQ
Can I use SeaText AI with Next.js output: 'export' (pure static export)?
Yes. Run SeaText content generation during next build, write the AI-generated copy into each page's HTML, and export. You get static files with personalized copy baked in. Dynamic personalization (per-visitor keyword, referral) won't work — every visitor sees the same pre-rendered version.
Does the SeaText snippet work on Astro, Remix, or Qwik?
The documentation covers React, Vue, Angular. The snippet is framework-agnostic JavaScript; it loads async and uses local storage. You place it in your HTML shell or entry point. Test Console/Network tabs as the SPA guide recommends.
How do I generate 125 language versions at build time without timing out?
Parallelize. SeaText's Translation Agent can batch-generate. Split your build into language chunks, run on multiple CI runners, or use ISR to generate low-traffic languages on first request. The dashboard tracks performance by language and market.
Can I A/B test variants on statically generated pages?
Yes. SeaText generates variants, you pick winners (or let the AI auto-select), then rebuild the static pages with the winning copy. For continuous testing without rebuilds, you need SSR/ISR so the snippet can serve different variants to different visitors.
What happens to bot detection on static pages?
The snippet runs in the visitor's browser and sends suspicious session data to SeaText. You get refund-ready reports. Server-side signals (headers, IP reputation) aren't available unless you add SSR/edge middleware.
Is there a performance penalty for the async snippet on static pages?
Minimal. The snippet loads after HTML parse, doesn't block LCP. The AI-generated copy is already in the static HTML, so the snippet mainly handles variant tracking, chat, scroll slowdown, and bot evidence collection.
Can I mix SSG and SSR in the same SeaText project?
Yes. That's the hybrid approach described above. Configure per route/page in your framework. SeaText's dashboard shows results aggregated across all rendering modes.
