Kissimmee and Dr. Phillips should not share a budget or a bid strategy
Different submarkets carry different plan mixes, different competitive pressure and different case values, so blending them hides all three.
Split the account by geography first and by procedure second. Most dental PPC advice reverses that order, which works in a compact market and breaks in one that spreads across two counties along an interstate.
Separate campaigns give you separate levers: budget, bid, ad copy, landing page and hours. If inquiries from one area book at a materially lower rate, you can cut it without also cutting the area that is working. Inside one campaign, you cannot.
Watch what the automation does with a blended budget. Smart bidding will chase whatever produces the cheapest recorded conversion, and that is usually the densest, most price-shopped part of the map, not the part where the case value sits.
Pacing follows the same logic. Benefit years reset in January and unused annual maximums expire, so the closing weeks of the year behave differently from the spring. Set that pacing per campaign rather than pushing one metro-wide budget curve.
