# Ahrefs Analytics

The c15t ahrefsAnalytics helper loads Ahrefs Web Analytics only after visitors allow measurement in Inth. You add one project key, and c15t removes the script when consent is withdrawn.

## Key facts

- **Tool:** Ahrefs Analytics
- **Category:** Analytics

Load Ahrefs Web Analytics only after visitors allow measurement. Add your project key in one line and keep the choice with the visitor.

Inth keeps the consent record of each choice, with the visitor’s country and the policy that applied.

## Before you start

You need an Inth project that connects to your app, c15t in that app and the project key from your Ahrefs installation snippet.

## How consent works with Ahrefs

Ahrefs says that its analytics sets no cookies. c15t still does not load analytics.js before the visitor allows measurement.

The c15t ahrefsAnalytics helper sends no consent signal to Ahrefs. It adds the script with your key as data-key only while measurement has permission.

If the visitor withdraws consent, c15t removes the script element and reloads the page by default.

## Installation

Ahrefs has one load mode in c15t. The helper waits for measurement permission.

### Wait for permission

No request goes to Ahrefs until the visitor accepts measurement.

```ts
ahrefsAnalytics({ key })
```

An opt-out policy or no policy gives optional categories permission before a choice. Then Ahrefs loads on the first page. This guide uses an opt-in policy.

## Setup steps

#### Install the integration package

Add the helpers next to c15t. An import alone does not start the Ahrefs script.

```
pnpm add @c15t/integrations
```

#### Add your project key

Copy the key from the Ahrefs installation snippet. The helper sends it to analytics.js as data-key.

```
import { ahrefsAnalytics } from '@c15t/integrations/ahrefs-analytics';

export const scripts = [ahrefsAnalytics({ key: 'YOUR_PROJECT_KEY' })];
```

An empty key logs an error, and the script does not load.

### Register it with your existing setup

#### Next.js

Add scripts to c15t.config.ts, next to next.config.ts. Keep the rest of your config, such as mode, in the same call. App Router, Pages Router and static export read the same file.

```
import { defineConsentConfig } from 'c15t/next';
import { scripts } from './src/consent-scripts';

export default defineConsentConfig({ scripts });
```

#### TanStack Start

Pass scripts to the ConsentRoot in your root route. Import helpers in the route module, not in a server function: script configurations carry callbacks.

```
import { scripts } from '../consent-scripts';

<ConsentRoot state={consent} scripts={scripts}>
```

#### React

Add scripts to the options of your ConsentProvider, next to mode. Keep the banner, dialog and preferences link inside the provider.

```
import { scripts } from './consent-scripts';

<ConsentProvider options={{ mode, scripts }}>
```

#### Nuxt

Register scripts under the c15t key in app.config.ts. Keep them out of nuxt.config.ts, which reaches the browser as JSON and drops the helper callbacks.

```
import { scripts } from '../src/consent-scripts';

export default defineAppConfig({
  c15t: { scripts },
});
```

#### Vue

Pass scripts to the c15tVue plugin call you have now. The plugin starts one script loader when the app mounts.

```
import { c15tVue, manifest } from 'c15t/vue/vue-plugin';
import { scripts } from './consent-scripts';

app.use(c15tVue, {
  mode: manifest(),
  scripts,
});
```

#### Astro

Add scripts to the client entrypoint, which the integration finds on its own. Keep helpers out of astro.config.mjs: its options are serialized into the page.

```
import type { C15tClientOptionsExtension } from 'c15t/astro';
import { scripts } from './consent-scripts';

export default { scripts } satisfies C15tClientOptionsExtension;
```

#### Svelte

Pass scripts as a prop to the ConsentProvider you have now. The provider owns the loader and disposes it on unmount.

```
<script lang="ts">
  import { ConsentProvider, manifest } from 'c15t/svelte';
  import { scripts } from './consent-scripts';
</script>

<ConsentProvider mode={manifest()} {scripts}>
  <!-- Your app and consent UI -->
</ConsentProvider>
```

#### SvelteKit

Add scripts to the ConsentRoot in the root layout. Import helpers in the layout component, not in +layout.server.ts: a server load cannot send functions to the browser.

```
<script lang="ts">
  import { ConsentRoot } from 'c15t/svelte';
  import { scripts } from '../consent-scripts';

  let { children, data } = $props();
</script>

<ConsentRoot state={data.consent} {scripts}>
  {@render children()}
</ConsentRoot>
```

#### HTML: Paste the vendor’s snippet behind consent

The helpers need a bundler. On a page with the c15t script tag, paste the vendor’s own snippet instead and keep it inert until visitors allow its category. Helper options, such as loadMode, do not apply.

```
<script type="text/plain" data-c15t-category="measurement">
  // The vendor's snippet, unchanged
</script>
```

#### JavaScript

Pass scripts to init() from @c15t/browser, next to your mode. With createConsentRuntime, pass scripts to it instead.

```
import { init, manifest } from '@c15t/browser';
import { scripts } from './consent-scripts';

const consent = init({
  mode: manifest(),
  scripts,
});
```

Remove the old Ahrefs snippet, so the script loads only through c15t. If you already have a scripts array, add the helper to it.

## Verify your setup

Use a private window with an opt-in policy. Open DevTools Network and filter by ahrefs. Then test the three states.

- **Before a choice**: No request goes to analytics.ahrefs.com. Click Reject and reload. There is still no request.

- **After you allow measurement**: analytics.js loads without a page reload. Its script element has your data-key.

- **After you withdraw measurement**: Save your choice. c15t reloads the page. The new page sends no request to Ahrefs.

If your code calls window.AhrefsAnalytics?.sendEvent, check measurement permission before each call.
