Install CampaignProof in Chrome

1. Get the extension

Unzip it somewhere you will keep it, for example your Documents folder.

2. Load it in Chrome

1. Open chrome://extensions in the address bar.
2. Turn on Developer mode (top right).
3. Click Load unpacked and choose the unzipped folder (the one that contains manifest.json).
4. Click the puzzle icon in the toolbar and pin CampaignProof AI.

3. Try it on a demo page

1. Open a demo landing page. Scenario A has every tag working; B is missing its Google Ads conversion; C fires Meta Lead twice; D sends GA4 in a format the browser does not expose; E has personal data in the URL.
2. Click the CampaignProof icon, then Import a workflow instead and paste the demo workflow.json, or type the events yourself.
3. Click Allow access for the site, then Start verification.
4. Fill in and submit the form, tick I completed the journey, and click Stop and verify.
5. Click View report.

The demo pages use fake tracking IDs, so no real account records anything. Their form is not sent anywhere.

Permissions, in plain words

• Read requests to Google Analytics, Google Ads and Meta. Only while you are recording, only in the recorded tab. Chrome describes this as reading data on those sites.
• Access to the site you test. Asked for one site at a time when you click Allow access; remove it any time from the extension's details page.
• Storage. Reports are kept in your browser (the latest 25).
