A lower cost-per-lead comes from tightening the whole funnel. Here are the five levers I pull first.
1. Search term hygiene
Mine the search terms report weekly and add negatives aggressively.
2. Match message to query
Tight ad groups with aligned ad copy and landing pages lift Quality Score and lower CPCs.
3. Fix conversion tracking first
Smart Bidding is only as good as the signal you feed it. Track real leads, not vanity clicks.
4. Use the right bid strategy
Scale with Maximize Conversions, then move to Target CPA once you have data.
5. Dayparting and geo-refinement
Concentrate budget where and when leads actually convert.
