Install on your platform

What every platform needs

Whatever builds your pages, three pieces go in three places:

The tag must be on every page. A page without it has no consent state, and its vendor scripts follow their own rules. After you publish, check a page from each template your site uses, such as the home page, a blog post and a product page.

WordPress

Add the tag to your child theme's header.php, right before </head>. Edits to a parent theme are lost when it updates. A block theme without header.php can print the tag from the child theme's functions.php:

add_action('wp_head', function () {
  echo '<script src="https://your-project.inth.app/c15t.js" defer></script>';
}, 1);

Priority 1 prints the tag before other plugins' head output. Replace the backend URL with your Inth project's URL.

Plugins that add analytics or pixels for you, such as a site stats plugin or a marketing integration, print active tags you cannot change to text/plain. Turn off that plugin's tracking output and paste the vendor's snippet as a gated tag instead, or keep the plugin and hold its requests with a network blocker rule.

Add the privacy settings link as a custom link in your footer menu, with the URL #c15t-preferences.

Webflow

Paste the tag in Site settings, Custom code, Head code. Paste gated vendor snippets there too, or in an Embed element for one page. Put the #c15t-preferences link in your footer component. Publish the site after each change; custom code does not run in the Designer.

Shopify

Edit your theme's code and paste the tag in layout/theme.liquid, before </head>. Put the privacy settings link in the footer menu with the URL #c15t-preferences. Checkout pages do not render theme.liquid, so the tag does not run there.

Apps that install tracking tags add them outside your theme. Check the page source for each vendor after you install c15t, and turn off an app's own tracking where it offers a setting.

Squarespace

Paste the tag in the Code Injection page's Header field. Code injection is not available on every plan. Add a footer link with the URL #c15t-preferences.

Wix

Add the tag as custom code in your site settings, placed in the head and loaded on all pages. Custom code needs a site plan with a connected domain. Add a footer link to #c15t-preferences.

Framer

Paste the tag in your site settings' custom code, in the section for the start or end of <head>. Add a link with the URL #c15t-preferences in your footer. Publish to see it on the live site.

Ghost

Paste the tag in Settings, Code injection, Site header. Add a navigation item with the URL #c15t-preferences to the secondary navigation, which most themes render in the footer.

Hugo

Add the tag to the template that renders <head>, usually layouts/_default/baseof.html or a head partial. Copy a theme's file into your own layouts/ directory before editing it, so a theme update does not overwrite your change.

Eleventy

Add the tag to the base layout in your _includes directory that every page extends.

Jekyll

Add the tag to _includes/head.html or _layouts/default.html. Copy a theme's file into your site before editing it.

Plain HTML and server includes

Add the tag to each page's <head>, or to the shared header include your server uses.

Tag managers

Do not load the c15t tag from Google Tag Manager or another tag manager. The tag manager runs its own tags before c15t could decide anything, and it is a vendor that needs consent itself. Load c15t directly in <head>, then gate the tag manager's snippet like any other vendor. Scripts covers Google Consent Mode.

Caching and optimization plugins

Plugins and CDN features that combine, defer or delay scripts can rewrite a gated tag's type, move it, or delay the c15t tag until the first click. Any of these breaks gating. Exclude the c15t tag, c15t.js, and every tag with data-c15t-category from script optimization. Then check the page source of the published site. Each gated tag still has type="text/plain" before a choice.

A full-page cache is safe. The tag reads the visitor's choice in the browser, so every visitor can get the same cached HTML.

Check it works

On the published site, open a page from each template in a private window with the Network tab open.

1. The banner appears, and filtering for each vendor's domain shows no request before a choice.
2. Click Reject All and open another page. The banner stays closed.
3. Click the footer's privacy settings link. The preference dialog opens.
4. View the page source. There is one c15t tag, and every vendor snippet is type="text/plain".
