A twenty five mile radius here buys you a lot of open water
Geography in this metro punishes circle targeting harder than it punishes almost anywhere else.
Draw a radius from a yard in Metairie or Mid-City and a large share of it lands on Lake Pontchartrain, the river and marsh. You pay for the impressions that fall on land, but the circle also reaches into places your crews will not go on a Tuesday.
Build the targeting from parishes and cities instead. Orleans as one group with its submarkets named. Jefferson with Metairie, Kenner and the West Bank. St. Tammany with Mandeville, Covington and Slidell held separately, because a job across the lake is a different day for a crew and should carry a different bid.
Set location targeting to people in your area rather than people showing interest in it. The French Quarter is full of visitors, and interest based targeting will happily sell you clicks from someone standing in a hotel lobby researching a contractor in another state.
Then look at the geographic report every month, not every quarter. Spend drifting toward places you do not serve is the most common leak in a local account and it is invisible from the campaign level.
