Bidding decisions should always come from data, not guessing. If a keyword is bringing in clicks but very few conversions, that means people are clicking your ad but not taking the action you want, like buying or signing up. In that case, lowering the bid makes sense so you spend less on it. But if a keyword is converting well and the cost per conversion is within your budget, raising the bid can get you more of those results. What signals do you usually look at before touching the bids in your campaigns?
