Squid ID runs from a single script tag. It loads the SDK by your SDK key and starts identifying visitors on the next page view. Install it once, site-wide, in the ``. ## The snippet Replace `YOUR_SDK_KEY` with the SDK key for your website, shown when you create a website and under Settings → Website. ```html theme={null} ``` The script is async and loads from app.asksquid.ai. It does not block page rendering. One snippet covers your whole site when it's placed in a shared header or template. ## Pick your platform Each guide covers exactly where the snippet goes on that platform. If yours is not listed, use the [Plain HTML](/getting-started/install/plain-html) steps, since the snippet works anywhere you can edit the page head. ## More platforms Any platform with a custom head or code-injection setting works the same way: paste the snippet into the head and it covers every page. Common places to find it: | Platform | Where to add it | | ------------------------ | ----------------------------------------------- | | Duda | Settings, then Head HTML | | Drupal | Theme head template, or a code-injection module | | Joomla | Template head, or a head-scripts plugin | | Unbounce | Page Javascripts, placement Head | | Instapage | Page settings, HTML/CSS, Head | | Carrd | Settings, Code, Head | | Bubble | Settings, SEO/metatags, script in the header | | Gatsby, Astro, Vue, Nuxt | Add the script to the document head | ## After you install Once the snippet is live and your site gets a page view, the dashboard connection status flips to Live and pinging. Go to [Verify your install](/getting-started/verify).
