Aggregate campaigns around signal thresholds.
Most B2B search accounts are over-segmented. Dozens of tightly scoped ad groups — each with too few impressions per week and too few conversions per month to give the algorithm anything to learn from. Smart bidding requires signal volume. Without it, the algorithm guesses.
We restructure the account around two thresholds:
- ≥ 3,000 impressions per week per ad group — the minimum for smart bidding eligibility, per Google's Smart Bidding team
- ≥ 30 conversions per month per campaign — the minimum for the algorithm to optimise reliably against a conversion target
Aggregating to these thresholds doesn't mean losing control. We retain strict relevance between search intent, ad copy, and landing page using dynamic ad attributes and keyword-level URL mapping. The structure compresses. The control stays.
