By the time someone sees your ad, most of the hard work is done. You tracked the right conversions, found the searches that book, built tight ad groups and set bids you can afford. Then a patient types "dentist near me," and your ad appears in a short list next to three or four others. In the second or two it takes them to decide, the only thing working for you is what your ad says.
That is why ad copy matters so much. The bid gets you onto the page. The ad gets the click. And as we covered in Chapter 4, how closely your ad matches the search is the part of Quality Score you have the most control over, which makes good copy cheaper as well as more persuasive.
The good news is that you probably do not have to write it from scratch. For most practices, the best ad copy already exists. It is on your website.
Your Website Already Wrote Most of Your Ads
Every practice that has put real thought into its website has already answered the questions an ad needs to answer: who you are, what you do, why someone should choose you, and what to do next. Ad copy is mostly the job of taking those answers and fitting them into Google's space limits.
Here is a real example from our Phoenix research. The landing page for Arizona Biltmore Dentistry leads with a set of short, specific trust signals, including "Free Teeth Whitening for New Patients" and "Over 1200 5-star reviews on Google," along with "Trusted Phoenix Dental Team" and "Friendly, Comfort-Focused Care." Each of those is already most of the way to being a headline. They just need trimming to fit.
"Free Teeth Whitening for New Patients" is 37 characters, so it becomes "Free Whitening, New Patients" at 28. "Over 1200 5-star reviews on Google" becomes "1,200+ Five-Star Reviews." "Friendly, Comfort-Focused Care" is exactly 30, and fits as it is. The message stays the same. Only the length changes.
A bad website still has good ad copy hiding in it
Plenty of practices sit down to pull ad copy from their website and find nothing specific to pull, just general phrases like "quality care" and "your smile is our priority." That does not mean starting from a blank page. The raw material still exists. It just lives somewhere else.
- Your reviews. Patients describe what they value in their own words: never felt rushed, great with my kids, explained everything, got me in the same day. Those phrases are often stronger headlines than anything a practice would write about itself, because they are what the next patient is hoping to hear.
- Your front desk and your dentist. The questions patients ask on the phone, the worries they bring to a first visit, and the way the dentist explains a treatment at a consultation. If the same question comes up every week, an ad that answers it will stand out.
- Your competitors. The research in the next sections shows what everyone else in your market is saying, and more usefully, what nobody is saying yet.
Then fix the page the ad sends people to, because the ad cannot do all the work. A weak landing page drags down the landing page rating from Chapter 4 and the conversion rate from Chapter 3, so you pay more for every patient. You do not have to rebuild the whole website first. A dedicated landing page for the campaign, one that says what your ads say, is usually the fastest fix.
The Chain Down the Street Can't Say What You Can
Your ad will rarely appear alone. On most dental searches, it sits next to national chains, large dental groups and specialists with bigger budgets than yours. An ad that could belong to any of them gives the patient no reason to choose you.
It helps to look at how others in your market position themselves. On an implant search in Phoenix in September 2026, ClearChoice's ad led with "One Cost, No Surprise Fees" and implants that "Cost As Little As a Cup Of Coffee a Day," while on an aligner search, Serrano Orthodontics offered "Invisalign At No Extra Cost" from a team of board-certified orthodontists. Both are clear and specific. On implant and aligner searches, price transparency is where the competition is happening.
An independent practice usually wins on different ground: the things a chain cannot say. The dentist by name. How long you have served the neighborhood. Your reviews. How you treat nervous patients and children. Same-day appointments, if you offer them. The insurance plans you take. Put those in your ads, because no one else on the page can.
Your Competitors' Ads Are Public. Read Them Before You Write Yours.
Before you write, look at what the practices around you are already saying. Two free tools make this easy.
The Ads Transparency Center. Google keeps a searchable record of the ads advertisers have run. When you see a competitor's ad, click the three dots next to it and look for the option to see more ads from that advertiser, or go directly to adstransparency.google.com and search by name or website. You can filter by date and location. If a practice's ads do not show up, the account may be run by an agency, in which case you may see the agency's name instead.
Ad Preview and Diagnosis. The same tool from Chapter 5, under Tools, then Troubleshooting. Search as if you were in your own city and see exactly which ads appear, without clicking any of them and without piling up impressions on your own ads.
Paid tools like SpyFu and Semrush can show longer ad histories if you want to go further.
The point is not to copy anyone. It is to see what offers and claims patients in your area are already being shown, so you can find what is missing and say something better. Sometimes you will find a phrase or an offer that belongs on your website too.
Fifteen Headlines Is an Allowance. Spend All of It.
Google's search ads are now responsive search ads. Google describes the format simply: you enter multiple headlines and descriptions, and "over time, Google Ads tests different combinations and learns which combinations perform best." You can provide up to 15 headlines of 30 characters each, and up to 4 descriptions of 90 characters each.
You do not have to fill every slot, but you should. More options give Google more combinations to test, and more chances to match what each patient searched.
A good set of dental headlines covers a few different jobs:
- The search itself. For the pediatric ad group, "Pediatric Dentist Near You." For the emergency group, "Same-Day Emergency Visits." This is what tells the patient they found what they were looking for.
- The service, in more detail. What you actually do for this need, in plain words.
- Trust. Reviews, years in practice, the dentist's name, credentials.
- The offer. A new patient special, free whitening, a free consultation, financing, the insurance you accept.
- The next step. "New Patients Welcome," "Book Your Visit Online Today," "Call for a Same-Day Visit."
Descriptions have more room, so use them to say one complete thing each: what the visit is like, why patients choose you, what the offer includes, and how to book.
Most important of all, write the ads for each ad group, not once for the whole account. Because your ad groups follow the keyword families from Chapter 5, every group has its own theme. The ad in the "pediatric dentist near me" group should talk about children. The ad in the implant group should talk about implants. That match between the search and the ad is exactly what earns strong ad relevance.
Pin a Headline After It Wins, Not Before
Google lets you pin a headline to a specific position, so it always shows there. It is tempting to pin everything you like best. For a new dental account, we usually do the opposite.
At launch, leave every headline unpinned. A new account does not yet know which of its headlines patients respond to, and neither do you. Unpinned headlines give Google the most combinations to test, which is the whole point of the format. Google's own guidance agrees: pinning "isn't recommended for most advertisers and can affect ad strength," because it cuts down the combinations Google can try.
Pin a headline once you know it wins. Sometimes a practice already has a line it knows works, from years of past advertising or from its best-performing page. Other times the account proves one over the first months. Either way, that is the time to pin it, usually to the first position, and let the rest keep rotating. Google itself suggests pinning "only 1 or 2 essential headlines" and leaving the others free.
A pinned ad will often show an Ad Strength rating of "Poor." That looks alarming, but it is not what it seems. Google's own help page is clear that Ad Strength "isn't used to calculate Ad Rank, Quality Score, or auction wins." It is feedback on variety, not a penalty, so do not let it talk you out of pinning a headline you know works.
Whether to pin, and what, depends on the practice. A practice with a proven offer or a well-known name may pin from early on. A brand-new practice will usually let Google test for a while first.
AI Is a Great Editor and a Terrible Starting Point
AI writing tools are genuinely useful for ad copy, as long as they come at the end of the process rather than the beginning.
Once you have done the research above, give an AI tool your website to read, then ask it for options: "give me 50 headlines of 30 characters or fewer for a pediatric dental ad group." Because it has read your site, the ideas will draw on your real services and your real voice. You will get a lot of filler, and a few lines that are better than what you had. Keep those, rewrite the rest, and check every one against the character limit and against what your practice actually offers.
What AI cannot do is tell you what makes your practice different, or what your competitors are saying this month. That comes from the website and the research. Start there, and AI becomes a fast way to generate options instead of a machine for generic copy.
An Ad Without Assets Is Half an Ad
Assets, which Google used to call extensions, add extra information to your ad and make it take up more of the page. For a dental practice, the most useful are:
- Sitelinks, links to specific pages under your ad. Serrano Orthodontics' Phoenix ad, for example, carried sitelinks for "No Extra Cost For Invisalign" and "Financial & Insurance," among others, each answering a question a patient is likely to have.
- Callouts, short phrases like "New Patients Welcome" or "Sedation Available."
- Structured snippets, lists such as your services or the insurance plans you accept.
- Call assets, so patients on a phone can tap to call directly.
- Images, real photos of your office, your team and your dentists, not stock images.
Assets matter beyond looks. As we covered in Chapter 4, the expected impact of assets is one of the factors Google uses to decide where your ad ranks.
The Ad You Launch With Is a First Draft
Ad copy is never finished. Google will show which headlines and descriptions are working and which are not. Every so often, replace the weakest ones with new ideas: a new offer, a new trust signal, a different way of saying the same thing. Over months, the ads get steadily better, and so do the Quality Scores and the costs that come with them.
Next, the Settings That Decide Who Sees Any of This
You now have ads written for each group of searches, grounded in your website, positioned against your competitors and built to be tested. The last step before going live is the one that quietly decides where all of this runs and who sees it: the campaign settings.
That is Chapter 9, Campaign Settings Before You Launch.
If you would rather have the copy written for you, we write, test and refresh the ads on every dental account we manage. Our Google Ads management starts from your website and your market, not a template.
