A dentist PPC agency is buying attention in one of the more expensive local categories there is, where a single implant or orthodontic case can justify a click price that would look absurd in most industries. That makes two things matter more than creative: how the auction actually prices a click, and who owns the account when the relationship ends. Both are decided before any campaign launches. This page covers what Google publishes about how ads are ranked and priced, what a management fee should buy, and the questions that separate an agency running your account from one renting it to you.
How the auction actually decides what you pay
Google describes Ad Rank as the formula deciding whether an ad shows and where it appears, and lists its inputs as your bids, the quality of your ads and website, the Ad Rank thresholds, the competitiveness of the auction, the context of the person's search, and the expected impact of assets and other ad formats. Crucially it states that even if a competitor bids higher than you, you can still win a higher position at a lower price with high-quality ads and landing pages. That is the whole economic argument for paying an agency: not that it will bid more aggressively, but that better matched ads and a better landing experience change the price of the same position. A practice competing against corporate groups with larger budgets is not automatically outbid, and an agency that talks only about budget increases has skipped its own value proposition.
What Quality Score is, and what it is not
Quality Score is often quoted at dentists as though it were the lever. Google describes it as a diagnostic tool meant to give a sense of how well ad quality compares with other advertisers, scored from one to ten at keyword level, built from expected clickthrough rate, ad relevance and landing page experience. It states explicitly that Quality Score is not an input in the ad auction, and that it should be treated as a diagnostic for identifying how ads affect the user experience rather than as a key performance indicator to optimise. The practical reading for a practice owner is that an agency reporting a rising Quality Score has not yet reported anything about your money. Ask instead for cost per booked consultation by treatment, and for the diagnostic to be used the way Google describes it: as a pointer to which keywords and landing pages need work.
Fee structures, and the one question that decides them
Agencies price dental PPC as a percentage of media spend, a flat monthly fee, a fee per campaign, or a hybrid with a performance element. Each has a bias worth naming out loud. A percentage of spend rewards spending more, which is fine when growth is the goal and awkward when efficiency is. A flat fee rewards low-touch accounts. A performance element needs a definition of a conversion that both sides trust, which for a dental practice means agreeing whether a phone call of a given length counts, and who listens to the recordings. Before any of that, settle ownership: the ads account, the conversion tracking, the call tracking numbers and the landing pages should belong to the practice, with the agency granted access. An agency that will not run the account inside your own billing has made leaving expensive by design.
Vetting the agency and its claims
Google's guidance on hiring search help transfers cleanly to paid media. Ask for examples of previous work and success stories, what results are expected and in what timeframe, how success is measured, how the agency communicates, and whether it will share every change made. Be sceptical of secrecy about methods, of unsolicited pitches, and of any claimed special relationship with Google. For a dental account, add the specifics: which treatments will be advertised and at what target cost per case, how calls are tracked and who reviews them, what happens to the campaigns during a holiday closure, and how quickly a wasted-spend query gets excluded. Ask also who writes the landing pages, since Google names landing page experience as one of the three components of its quality diagnostic and it is the part most often left to the practice by default.
Questions people ask about dentist ppc agency
Does the highest bidder always win the top ad position?
No. Google states that even if a competitor bids higher, you can still win a higher position at a lower price with high-quality ads and landing pages. Ad Rank combines bid, ad and website quality, thresholds, auction competitiveness and search context.
Should we judge an agency on Quality Score?
Not as a headline metric. Google calls it a diagnostic tool and says it is not an input in the ad auction, so use it to find weak keywords and landing pages, and judge the agency on cost per booked consultation instead.
Who should own the Google Ads account?
The practice. Keep the ads account, conversion tracking, call tracking numbers and landing pages in your own name and grant the agency access. Agencies that hold the account make leaving costly and make history impossible to audit.
How should dental PPC be reported?
By treatment: spend, calls and forms, booked consultations, and cost per booked case, with call recordings reviewed by someone at the practice. Impressions, clicks and Quality Score are diagnostics, not results.
