A Michigan gutter company tripled its real leads

The company was spending on Google Ads, but most of the "leads" were people tapping for map directions or brushing a call button, not people asking for a quote.

A new website, rebuilt campaigns, and tracking limited to real phone calls and form submissions changed what the account reported.
