I can run that audit. To find real waste I need four things first:
- Search terms report for the last 30 days (CSV export) with campaign, ad group, match type, cost, clicks and conversions, plus conversion value if you track it.
- Campaigns report for the same period with each campaign's daily budget, whether it's "limited by budget," its bid strategy, whether Search Partners and Display expansion are on, and the location option (presence or presence or interest). I need this to spot budget leaks and settings problems.
- Your target CPA or ROAS, per campaign if they differ. I won't guess this, because every "is this waste" call depends on it.
- A short business description: what you sell, to whom, where, and what you don't offer.
Optional: the Keywords report for the same period, so I can recommend keyword pauses or bid changes, and how many clicks a keyword needs before we judge it (default 30).
Can you send those over? I'll only draft changes; nothing gets applied to your account without your approval.
