Choosing the wrong bid strategy for a campaign's maturity level is one of the most common causes of a campaign going dark — spending nothing despite having an active budget. The core rule: Maximize Conversions requires historical conversion data to function. Without it, Google's algorithm has nothing to learn from and bids so conservatively the campaign effectively stops serving.
This pattern was directly observed in Bluepoint's "Reverse ATM" search campaign, which had a $28/day budget and received only 2 impressions over its entire run — caused entirely by launching with Maximize Conversions on a brand-new campaign with zero conversion history.
How Maximize Conversions works: Google's algorithm predicts which clicks are most likely to convert and bids accordingly. This prediction relies on historical conversion data from the campaign. With no prior conversions, the algorithm has no signal — it bids extremely conservatively or not at all.
Symptoms of this failure mode:
- Campaign is enabled and has an active budget
- Impressions are near zero (2, 5, 10 — not thousands)
- Spend is zero or negligible
- No error messages; the campaign appears healthy at a glance
Diagnostic approach: Export campaign performance as a CSV and ask an AI assistant "why is [campaign name] getting no impressions?" — this will typically surface the bid strategy mismatch as the likely culprit within seconds.
Maximize Clicks does not require conversion history. It simply tries to drive as many clicks as possible within budget, which generates the traffic needed to accumulate conversion data.
This is a temporary state, not a permanent strategy. Maximize Clicks optimizes for volume, not quality — it will drive traffic regardless of conversion likelihood.
When switching to Maximize Clicks, a modest budget increase is often necessary. A campaign that was starved under Maximize Conversions may still underperform at its original budget because the algorithm needs room to explore. Raising by 25–50% is a reasonable starting point.
| Situation | Recommended Strategy |
|---|---|
| New campaign, no conversion history | Maximize Clicks |
| Campaign has 15–30+ conversions | Maximize Conversions |
| Campaign has 30+ conversions and stable CPA | Target CPA (most precise) |
| Need impressions/brand awareness, not conversions | Maximize Clicks or Target Impression Share |
A campaign with a meaningful daily budget and near-zero impressions is a red flag that should be caught during routine optimization reviews — not discovered weeks later. Key things to check:
When flagged, the account manager should be notified immediately so they aren't caught off guard in client calls.
