Emergency, elective and new patient exam are three accounts wearing one login
Those three searches come from different people, close on different timelines and are worth different amounts, so they should never share a budget.
Urgent searches convert within the hour or not at all. Someone with a cracked molar on a Tuesday morning calls the first practice that answers, and the value of that click is whatever a same day visit is worth to you.
Elective work behaves nothing like that. Implants, orthodontics and cosmetic cases involve research, price comparison and often a spouse. Clicks cost more, the consideration window is weeks, and judging that campaign on a seven day window will get it shut off before it can prove anything.
Routine exams and hygiene sit in the middle: cheaper clicks, higher volume, and a ceiling set by how many hygiene slots you actually have open. Buying more of them than you can seat is spending to create a waitlist.
Split them into separate campaigns with separate daily budgets that never borrow from each other, separate ad copy and separate landing pages. One blended campaign will spend all of it on whichever type is cheapest, which is rarely the one you need.
