Short answer
A beginner dental Google Ads campaign should be structured around specific services rather than one broad campaign, include call tracking from day one, and use a negative keyword list to filter out irrelevant searches, all of which matter more to early results than most of the advanced settings dentists often get distracted by.
Structure campaigns by service, not as one broad account
A single campaign covering every dental service you offer makes it hard to tell which specific services are producing a good return, and tends to waste budget on broad, low-intent keywords. Separate campaigns for general dentistry, cosmetic dentistry and implants, for example, allow different budgets, bids and landing pages matched to how valuable each type of patient actually is.
Set up call tracking before launching, not after
A significant share of dental enquiries still happen by phone, particularly for higher-value or more urgent services. Without a dedicated tracking number connected to your campaign, you're reporting on clicks rather than actual enquiries, and you have no way to tell which specific keyword or ad produced a phone call versus one that only produced a click that went nowhere.
Use negative keywords to protect your budget
Without a negative keyword list, a dental Google Ads account will often waste meaningful spend on searches for dental assistant jobs, dentistry courses, or free information the searcher was never going to pay for. Building this list early, and reviewing search terms regularly to add to it, protects budget that would otherwise go to searches with no genuine booking intent.
Common beginner mistakes worth avoiding
Sending every ad to your homepage rather than a page specific to what the ad promised is one of the most common conversion killers. Setting a budget too low to generate meaningful data, then judging the campaign as a failure, is another. And ignoring the account for weeks at a time after launch, rather than reviewing search terms and performance regularly in the first month, leaves obvious optimisation opportunities on the table.
What to expect in the first month specifically
In week one, expect to spend time on setup, conversion tracking, negative keywords, and initial ad copy, rather than seeing much in the way of results yet. By weeks two and three, enough data usually exists to start identifying which keywords and ads are performing and which are wasting spend, allowing for a first round of genuine optimisation rather than guesswork. By the end of the first month, a well-set-up campaign should have a reasonably clear, evidence-based picture of cost per enquiry for your main services, which becomes the baseline for deciding whether and how to scale the budget going forward.
Why watching your competitors' ads can teach you something useful
Searching for your own core keywords periodically and looking at which competitors are advertising, and how they have written their ad copy, gives a genuinely useful, low-cost source of insight into what messaging and offers are common in your specific market. This is not about copying a competitor directly, but about understanding the competitive landscape you are entering and identifying a genuine point of difference for your own ads rather than guessing blind at what might work.
