Two people in the same city search Google on the same morning. One types "heel hurts." The other types "podiatrist." Both have sore feet. Only one of them has decided to see a doctor.
Advertisers price that difference into every click. In our example market, Los Angeles, Keyword Planner estimated that a top-of-page spot for "heel hurts" went for 5 to 51 cents. For "podiatrist," it went for $1.78 to $8.34. At the high end, that's about 16 times as much for one word.
A podiatry account that sets one bid for everything gets both of those wrong. This chapter covers how to bid by hand in the first campaign, which numbers tell you when to move a bid, and when it's safe to let Google take over.
A "Podiatrist" Click Costs About 16 Times What "Heel Hurts" Does in Our Example Market
The gap isn't one odd pair. We sorted the podiatry searches from our 12 Keyword Planner pulls (every search with at least 50 a month) into three groups and averaged the high end of each one's top-of-page range, weighted by volume:
- Searches that ask for a doctor ("podiatrist," "foot and ankle specialists," "podiatrist doctor near me"): about $6.81.
- Searches that pair a doctor with a foot problem ("podiatrist ingrown nail," "plantar fasciitis doctor," "podiatrist nail fungus"): about $5.78.
- Searches that only describe the foot problem ("heel hurts," "corns on feet," "fungus toe nails"): about 89 cents.
That's roughly 7.7 times between the first group and the last. Our read on why: the person asking for a doctor is close to booking, so every practice in the auction is willing to pay for them, while the person describing a sore heel may still be reading about stretches. Chapter 2 showed how few heel pain searches ask for a doctor at all.
Keyword Planner's prices are estimates from other advertisers' recent auctions, so allow about 30% either way. The shape is what matters: the searches a podiatry account wants most are the expensive ones, and a single bid can't be right for both ends.
One Bid for Every Search Overbids on Heel Pain. Each Podiatry Ad Group Needs Its Own.
In the first campaign, which we call Isolation, bids are set by hand. Google's name for it is Manual CPC. The practice decides the ceiling on each click, either as one number shared by an ad group or a separate number per keyword, and we use the ad group number. (Isolation is BrandRocket's name for the exact match campaign from Chapter 6, not a Google setting.)
That's where Chapter 4's structure pays off again. Because each ad group holds one foot problem, each one can carry a bid that fits its own searches. In our example market, the ranges looked like this:
- "Podiatrist near me" and its wordings: $1.46 to $6.25
- Ingrown toenail ("podiatrist ingrown nail," "ingrown nail removal near me"): about $1.16 to $4.98
- Fungus ("podiatrist nail fungus"): $1.40 to $6.32
- Heel pain ("plantar fasciitis doctor"): $1.58 to $6.20
- Bunions ("bunion op"): 42 cents to $4.19
Start each bid near the top of its range. A new account has no history with Google, and a new ad has no track record to lean on, so early bids have to do more of the work of reaching the top of the page. As results come in and the ads prove themselves, bring the bids down a step at a time. Google's own advice on manual bidding is to re-check bids regularly, because search traffic keeps changing.
One search deserves a lower bid than its price suggests: plain "podiatrist." It carries the highest range in our list, up to $8.34, but Chapter 6 showed it's a mixed search, part people looking for a doctor and part people looking up the word. Bid it below the "near me" group until your own numbers show it books patients.
Where the money goes first is a business choice as much as a bidding one. If your practice is built on nail care, the ingrown toenail and fungus groups get the budget before the bunion group. Chapter 3 showed how to price each service; a foot problem that's worth more to the practice can carry a higher bid.
Impression Share Shows Whether Your Ingrown Toenail Ad Reaches the Top of the Page
A manual bid is only as good as the numbers you check it against. Four columns in the keyword and ad group reports do most of the work:
- Search top impression share. The share of chances to sit above the unpaid listings that the ad actually took. On the searches that matter most, like "ingrown nail removal near me," aim for 75% to 90%.
- Search absolute top impression share. How often you held the very first ad position. It isn't always worth paying for, but on your best-converting searches it's worth watching.
- Impression share lost to rank. How often your ad missed out because its Ad Rank was too low. If this is high, either the bid or the ad and page (Chapter 4) need work.
- Quality Score, at the keyword level. The diagnostic from Chapter 4. A keyword with a low score and a high lost-to-rank number needs a better ad or page before it needs a bigger bid.
Read together, they tell you which lever to pull. High lost-to-rank with a strong Quality Score usually means the bid is too low. High lost-to-rank with a weak Quality Score means fix the ad or the page first, because raising the bid just pays more for the same problem.
In the first month, look at these columns for each foot problem at least once a week, and move bids in small steps. A small podiatry account doesn't collect many clicks in a week, and one rival raising a bid on "podiatrist near me" can swing the numbers for days. Small, steady changes let you see which one worked.
Auction Insights Names the Practices You're Paying to Outbid
For any search campaign, ad group or keyword, the auction insights report shows who else appeared in the same auctions and how you compared. The report has six columns; for a podiatrist, overlap rate and position above rate do most of the talking. It won't show anything until your impression share is at least 10%.
For a podiatry practice, this is where you meet the market. You might find a multi-location foot and ankle group, a hospital system, or a solo practice down the road that ranks above you 80% of the time on "podiatrist near me." Overlap rate tells you how often they show when you do. Position above rate tells you how often they're ahead of you.
The report also tells you when to stop. If one competitor is pushing a search past what a booked patient is worth to you, you don't have to follow. Step back from that auction, lower the bid or pause the keyword, and move the money to a foot problem where you can hold the top of the page for less. Chapter 3's numbers are the ceiling: no click is worth more than the patient it's likely to bring.
A Cost per Lead Means Nothing Until Someone Listens to the Calls
Before any of these numbers can guide a bid, the conversions under them have to be real. A podiatry phone line gets plenty of calls that last 30 seconds or more and aren't new patients: an existing patient moving an appointment, someone asking whether their orthotics are ready, a billing question, a sales call from a supplier.
If those count as conversions, your cost per lead looks better than it is, and every bid decision built on it is off. So someone at the practice, or at the agency running the account, should listen to a sample of the calls each week and check that the ones counted as leads are people looking for a new appointment. Chapter 1 set up the ladder: calls and forms are the leads, and the booked patient, sent back to Google by click ID, is the conversion that matters most. Forms need the same check. An appointment form on a podiatry site collects its share of spam, job applicants and people asking for a medical records copy. Count a form as a lead only when it's someone asking to be seen. Call review is how you keep the first rung honest.
Broad Match Gets a Target Cost per Lead Only After Isolation Shows What One Costs
Chapter 6's broad match campaign, Exploration (our name, not Google's), switches on when Isolation is bringing in about 30 real podiatry leads a month. Many practices reach that in month two or three. A practice spending more reaches it faster.
Exploration doesn't bid by hand. Its bidding runs on Maximize Conversions with a target CPA. The practice names an average price per lead, and Google adjusts the bid search by search to hit it. Since June 2026 Google labels this strategy simply "Target CPA." The settings and behavior are the same.
The target comes from Isolation's real results, not a guess. Google's help page lands in the same place. For a campaign with history, the suggested target is what a conversion cost on average across the previous 30 days, and Google says to judge results on 30 or more conversions.
Here's how the handoff might look. Say Isolation spent $1,140 last month and counted 36 conversions. Call review removes 6 that were existing patients and billing questions, leaving 30 real new-patient leads. That's $38 a lead, which happens to match the benchmark estimate from Chapter 3. In a real account the number will differ, and the real number is the one to use.
Resist the urge to set the target lower than what Isolation actually paid. A target below what Isolation really paid starves the campaign: Google says an aggressive target can mean fewer conversions, since it skips searches that might have turned into a heel or toenail appointment. Start at the real number, let Exploration learn for a month or two, and lower it gradually once it's delivering.
If you'd rather have someone set the bids, read the impression share and review the calls every week, that's what our Google Ads management team does for podiatry practices.

Bids decide where your ad shows. The words decide whether anyone clicks. Chapter 8 shows where the best podiatry headlines are already hiding: in what patients say about the doctors they've seen.
For the two campaigns these bids belong to, see Chapter 6. Every chapter is on the guide home.
