Beltway drive time, not a mileage radius, should draw your targeting map
A circle on a map ignores the river, the bridges and an hour of morning traffic.
Draw a twenty mile radius from a shop in Tysons and it swallows half the District, which your truck may or may not reach by eight in the morning depending on the day. Draw the same circle from Capitol Hill and it collects parts of Prince George's County you may not want.
Build targeting from explicit place lists instead. Name the cities, counties and ZIP codes you actually serve and exclude the rest. It takes longer to set up and it stops the single largest source of waste in a remodeling account here.
Check the location option that decides whether you reach people present in an area or merely interested in it. The default catches researchers who are nowhere near the house, which matters in a metro full of people planning moves from elsewhere.
Once you have close rate by area, adjust bids toward the places where jobs actually sign. Click volume from a dense area is not the same as revenue from it.
