# Google Ads Account Audit with Elbert van der Waal

> Pre-Call Review (Optional): If you share your 10-digit Customer ID below, I will send a Read-Only link request before our call to review your setup in advance. Read-only access lets me view campaign data only. It gives zero editing permissions, and your billing info remains completely hidden. I will unlink my account within 24 hours after the call, or you can revoke access at any time. If you prefer not to share it, no problem at all. We will simply review your account live via screen share.

- Required fields: `name` (Your name), `email` (Email address), `What-is-your-company-website-URL` (What is your company website URL?)
- Optional fields: `customer_id` (Add your CID so I can run a free diagnostic before our call. I will only request Read-Only access (no edit rights, no billing visibility). If your company policy doesn’t allow this, leave blank and we’ll screen-share live.)
- `name` and `email` go in `attendee` and `guests` is a list of emails; every other field goes in `bookingFieldsResponses` under its name.
