There are two distinct approaches to working with keywords:
Tight ad groups = 1-3 near-identical keywords per ad group in [exact] or "phrase".
Broad+Smart = the same ad group idea but keywords without quotes or brackets (broad match) plus an automated bidding strategy like Maximize conversions or Target CPA.
What a first-timer should do- For your first $1,000: use tight ad groups only.
- Why: you control which searches you pay for, and your negatives work.
- When to expand: after one ad group gets 3-5 real conversions in 7-14 days and search terms are clean, duplicate it and test broad+Smart.
Switch checklist- You have 3-5 conversions from one ad group in the last 7-14 days.
- Cost per lead is close to target.
- Negatives list is cleaned weekly.
- Location option is Presence only.
How to test safely- Duplicate the winning tight ad group.
- Remove quotes and brackets so the keywords are broad.
- Set bidding to Maximize conversions. Keep sitelinks and callouts. Watch search terms daily for a week and add negatives fast.
