Frequently Asked Questions about Wasted Ad Spend
Why are my Google Ads getting clicks but no leads?
Clicks without conversions indicate weak keyword search intent (broad match waste), landing page friction, or broken conversion tracking.
How much wasted ad spend is normal in Google Ads?
In unoptimized accounts, up to 40% of spend is wasted. Weekly negative keyword auditing reduces waste to under 5%.
