How much budget should I start with?

A common mistake is launching campaigns with budgets that are too small to collect meaningful data. Instead, estimate: Monthly search volume × Expected CTR × Estimated CPC If your keywords cost around $8 per click and you want at least 300 clicks per month, you'll need roughly: 300 × $8 = $2,400 monthly budget. For lead generation campaigns, many advertisers start with enough budget to generate at least 20–30 expected conversions per month, giving Google's Smart Bidding enough data to optimize effectively.
