Don't see your website builder in the list? Your Sales Assistant snippet works on almost any platform. The only thing that changes is where you paste it. Before you start, [launch your Sales Assistant and copy your install snippet](/docs/solutions/sales-assistant/deploying/overview). Keep it on your clipboard, you'll paste it in below. ## The general rule Almost every website platform has a place to add custom HTML or scripts. Look for an option named something like: * **Custom code** * **Header / Footer scripts** * **Code injection** * **Embed code** * **Add script to `` or before ``** Paste your EasyMate snippet there, and set it to apply to **all pages** if asked. Whenever you get to choose a location, **before the closing `` tag** (sometimes labeled "Body - end" or "Footer") is the most reliable. Using Google Tag Manager? Follow the [Google Tag Manager](/docs/solutions/sales-assistant/deploying/google-tag-manager) guide instead, it deploys the widget as a tag. This covers popular one-page and simple site builders too, such as Carrd, Typedream, Instapage, and Cargo. Look for their custom-code or embed option (often on a paid plan) and paste the snippet there. If your builder has no custom-code option at all, it can't run the chat widget. ## Plain HTML websites If you manage your own HTML files, paste the snippet right before the closing `` tag in each page where you want the chat. If your site uses a shared footer or template include, add it there once so it applies everywhere. ```html theme={null} ``` (Use the real snippet from your Launch screen, not this shortened illustration.) ## Verify it's working 1. Open your live site in a new browser tab (or an incognito window). 2. Look for the chat button, usually in a bottom corner, and send a test message. If it doesn't appear, see [Troubleshooting](/docs/solutions/sales-assistant/deploying/troubleshooting).
