Step‑by‑step: how to embed chat

1) Pick your chat

Choose a solution that fits your budget, support goals, and setup time. If you want AI answers, lead capture, and low maintenance, pick Asyntai.

For sales‑led teams: Use proactive greetings on pricing and product pages.
For support‑heavy sites: Add links to help articles and order lookups.
For small teams: Let AI answer FAQs and hand off complex chats.

2) Get your embed code

Most tools provide a JavaScript snippet (1–2 lines). Save it in a doc or password manager so your team can reuse it. If there’s a plugin (e.g., WordPress), you may not need the code at all.

Have a staging site? Test there first so you don’t disturb live visitors.
Note any Content Security Policy (CSP) rules you might need to update.

3) Decide where it goes

Common placements: site‑wide in the footer, or only on key pages like pricing, product, and contact. Start where conversations impact revenue the most.

High intent: Pricing, checkout, demo booking.
Research: Blog, docs, resource pages.
Existing users: Dashboard, account, order tracking.

4) Paste the code

Add it before the closing </body> tag, or follow your CMS/plugin instructions. For single‑page apps, ensure it initializes after the app mounts.

5) Configure and test

Set colors, position, greetings, and triggers. Test on desktop and mobile, dark/light mode, and slow networks. When everything looks good, go live.

Check that the widget doesn’t cover cookie banners or key buttons.
Verify keyboard navigation and screen‑reader labels.
Send a few real test chats and confirm email/CRM notifications.

Platform tips

WordPress

Use a plugin or add code in your theme/footer. Most sites add it via Appearance → Theme File Editor → footer.php or a header/footer injector plugin.

// functions.php
function add_chat_widget() {
    echo '<script>/* Chat embed code */</script>';
}
add_action('wp_footer', 'add_chat_widget');
        

Tip: If you use caching, purge cache after adding the script.

HTML/static site

Paste the script before </body>. Keep it in a shared layout file so it loads site‑wide.

<!-- Before closing </body> -->
<script>
  (function() {
    var s = document.createElement('script');
    s.src = 'https://widget.chatplatform.com/widget.js';
    s.async = true;
    document.head.appendChild(s);
  })();
</script>
        

Shopify

Install an app or add the snippet in Online Store → Themes → Edit code → theme.liquid just before </body>. Test on product and cart pages.

Step‑by‑step:

Go to Online Store → Themes, click Customize for your live theme, then Edit code.
Open layout/theme.liquid and find the closing </body> tag.
Paste your chat snippet right above it. If your provider supports async, add async to the script tag.
Save, then preview your store and test on product, cart, and checkout (Shopify restricts checkout for some scripts—use app blocks if needed).

Theme app blocks: If the chat tool offers a Shopify app, you can add it as an app block to specific templates (e.g., product page only). This gives you more control without editing code.

Common patterns: Many stores show a proactive message on the cart page like “Questions about shipping or returns?” and a discount‑qualifying prompt on product pages after 15–20 seconds of dwell time.

Performance tip: Don’t include the widget in theme.js bundles. Load it separately and asynchronously so it doesn’t block product image galleries or variant scripts.

Analytics: Track chat‑started events in GA4 by pushing a dataLayer event when the widget opens or a message is sent.

Wix/Squarespace

Use their HTML/embed blocks or code injection settings. For Squarespace: Settings → Advanced → Code Injection → Footer.

Wix: Use Add → Embed → Embed a widget, then paste the code. Alternatively, use Settings → Advanced → Custom code and add it to all pages in the Body - end position.

Squarespace: Go to Settings → Advanced → Code Injection → Footer and paste the snippet. For selective placement, add a Code block on chosen pages.

Design considerations: These builders often have cookie banners and announcement bars. Offset the chat from the bottom by 16–24px so nothing overlaps. Ensure z‑index is above sticky navs.

Example: On a photography portfolio, trigger the chat only on the pricing page to answer questions about packages and deposits. On the homepage, leave it passive to avoid distracting from the hero visuals.

React/Angular

Load the script after the app mounts, or use a chat component. Reinitialize on route changes if your router doesn’t do a full page reload.

React example:

// App.tsx
useEffect(() => {
  const s = document.createElement('script');
  s.src = 'https://widget.chatplatform.com/widget.js';
  s.async = true;
  document.head.appendChild(s);
}, []);

// Reinit on route changes (if needed)
const location = useLocation();
useEffect(() => {
  window.ChatWidget && window.ChatWidget.reinitialize?.();
}, [location.pathname]);
        

Angular example: In ngAfterViewInit of a root component, append the script. If using the Angular router, subscribe to Router.events and reinitialize on NavigationEnd.

SSR/Next.js: Use next/script with strategy="afterInteractive". For dynamic rendering, guard against window being undefined.

State and theming: Expose a small configuration object on window before loading the script to pass theme color, language, or user info (if allowed).

Customize the look and behavior

Match your brand: colors, fonts, size, corner position, and open/close behavior. Set triggers (e.g., time on page, exit intent), business hours, and welcome messages. Make sure it’s responsive so it feels great on phones.

Visual: Use your brand colors and a friendly avatar; keep contrast high. If you use dark mode, ensure the widget switches themes or maintains readable contrast.
Positioning: Bottom‑right is standard; offset if you have a cookie banner. On mobile, consider a slightly larger bottom spacing (24–28px) to avoid OS UI elements.
Behavior: Don’t overdo popups. One proactive message per session is plenty. Use soft triggers like time on page or scroll depth, not on load for every visit.
Copy: “Need help deciding?” or “Got questions about shipping?” convert better than generic lines. Match the greeting to the page intent.
Hours: Set expectations. If you’re offline, show reply time estimates or offer to email the answer automatically.
Lead capture: Ask for email only after value is offered (e.g., after answering a question), not before.
Security: Never ask for passwords or sensitive data. Provide safe links for account actions.

Examples:

SaaS pricing page: “Want help picking a plan? Tell me your team size.”
E‑commerce product page: “Not sure about sizing? I can help you choose.”
Local services: “Need a quote today? Tell me your location.”

Best practices

Performance: Load asynchronously; defer heavy assets; avoid duplicate loaders. Lazy‑load emojis and images inside the chat if the platform allows.
Privacy: Use HTTPS, display your policy, and configure consent where needed. Limit PII collection and set retention periods.
Compatibility: Test Chrome, Safari, Firefox, Edge, iOS, Android, dark mode. Check right‑to‑left layouts for languages like Arabic/Hebrew.
Accessibility: Ensure keyboard focus, ARIA labels, and readable text. Verify focus doesn’t trap users in the widget.
CSP/CDN: If you use CSP, add the chat domain; serve assets via a fast CDN. Pin versions if your CSP is strict.

Troubleshooting

Chat doesn’t show

Place the code before </body>, check the console for errors, and disable ad‑blockers while testing. Verify your CSP allows the script source.

Confirm the script actually loads (Network tab → 200 OK).
Check that window.ChatWidget (or similar) exists after load.
Ensure no JavaScript errors earlier on the page prevent execution.

Layout looks off

Adjust the position or z‑index. Check for conflicting CSS and ensure the widget isn’t covered by banners.

Try z-index: 2147483000 on the widget container if layering conflicts.
Add bottom/side offsets to clear cookie banners or sticky navs.

Site feels slow

Load the script async/defer. Use a trusted, fast chat provider and monitor Core Web Vitals.

Record a Lighthouse report before/after embedding and compare.
Defer non‑critical features (emoji packs, rich previews) to idle time.

SPA route changes

If chat disappears on navigation, reinitialize on route changes or enable SPA mode in settings.

For React Router, reinitialize on location.pathname change.
For Angular, reinitialize on NavigationEnd events.

Advanced options

Dynamic content: Show page‑specific greetings (e.g., pricing vs. blog). Use UTM parameters to tailor messages for campaigns.
Auth: Personalize for logged‑in users (names, plan, recent orders). Hide sensitive data and follow least‑privilege principles.
Analytics: Track chats, leads, and conversions in GA/GA4. Create funnels to see where chat assists conversions.
Localization: Serve multiple languages and detect browser locale. Provide a language switcher if auto‑detection fails.
Integrations: Send leads to your CRM, Slack, or help desk via webhooks. Use tags (e.g., "pricing","shipping") for routing and reporting.

How to know it’s working

Speed: Track page load before/after embedding (aim for minimal impact). Watch Largest Contentful Paint (LCP) and Total Blocking Time (TBT).
Open rate: % of visitors who open the widget (5–15% is common). Improve with clearer, page‑specific greetings.
Engagement: % who send a message after opening (20–40% typical). Reduce friction; keep the first reply instant with AI.
Outcome: Leads captured, bookings, or sales from chat flows. Attribute with UTMs and event tracking.
Reliability: Uptime and error rate over time. Set alerts if errors spike.
