An account with thousands of keywords gets reviewed at the top and ignored underneath. That is where the money leaks.
Ppc management companies give you people, and people cannot read ten thousand search terms a month. The best bid management software gives you rules, and rules with nobody watching are how accounts drift.
Ppc automation is only useful with both: the reading done at scale, the judgment kept with a person.
No bid change without enough clicks behind it, no change more often than the interval you set, and no budget or ad text touched.
The industry has settled on read freely, draft, approve, and this holds that line rather than promising autonomy.
Automated bidding moves bids. Budgets are a business decision.
Google Ads, Microsoft Ads, Meta, and Windsor.ai for cross platform data.
Only where you allow it. Negative keywords are the single automatic action.
Untouched.
Every proposal and change is logged with its reason.
