Two things changed on Oct 1. Broad match was switched on for “Coffee – Generic”, and the daily budget went up 40%. Since then, two search terms that never convert ate €680.
I'd add them as negatives and move part of that spend to “buy whole bean coffee”, which converts at €13.
| Term | Cost | Conv. |
|---|---|---|
free coffee samples Add as negative | €412 | 0 |
coffee machine repair Add as negative | €268 | 0 |
buy whole bean coffee Raise bid 15% | €190 | 14 |
espresso subscription Keep | €156 | 11 |

Questions, answered.
Anything else? We read every email.
Will it change my campaigns on its own?+
No. Ads Harness reads your accounts freely, but every change (budgets, bids, keywords, new ads) is listed for you first and only goes live after you approve it.
Do I need to be technical?+
No. You talk to it in plain words, the same way you'd brief a colleague. A built-in setup guide walks you through connecting your accounts.
Which AI does it use?+
Claude, by Anthropic. You can use the Claude subscription you already have, or an Anthropic API key. Image generation uses OpenAI's GPT Image, if you add a key.
Is my data safe?+
Ads Harness runs on your Mac. Your credentials are encrypted in the macOS keychain and never handed to the AI; your account data goes only to Google and to the AI provider you choose.
Can I manage client accounts?+
Yes. Connect a manager (MCC) account and every client under it shows up, each with its own chats, history and business notes.
What about Meta, TikTok or LinkedIn ads?+
Google Ads comes first. Tell us which platform you want next.
Stop babysitting dashboards. Start growing.
