A Lakeway address costs more to serve than a Circle C address, so stop bidding the same on both
Cost to serve varies enormously across this metro, and a bid that ignores it buys you your least profitable doors.
West of the city, terrain does the damage. Slope, limestone and long private drives around Lakeway, Bee Cave, West Lake Hills and Dripping Springs make a routine vendor visit longer, and anything involving digging harder to price before someone looks at the site.
Compare that to a flat, uniform street in Circle C or a newer block in Pflugerville, where your plumber knows the floor plan before he parks. Same management fee, very different margin.
Split the campaigns geographically and set bids to match the work, not the click volume. If a Hill Country door only pays when the fee is higher, either bid less for it or send that traffic to a page that states the different fee.
Radius targeting drawn around your office is the crudest possible version of this. Draw the map from your vendor bench and your dispatch reality instead.
