Most optometry practices feel January before they see it in a report. The phones are busier, the schedule fills faster, and the front desk is fielding questions about benefits that just renewed. Google's search data shows the same thing, and it shows it in advance: the searches that book eye exams nearly double in the first month of the year.
That rush is where a Google Ads account either earns its year or leaks it. An account that goes into January with December's budget runs out of money by midday, and the afternoon's searchers go to whoever is still showing. This chapter covers how we set bids in Isolation, how to read impression share and auction insights, and how to have the account ready before the rush instead of scrambling during it.
The Eye Exam Calendar Has One Big Month
Google's Keyword Planner shows the pattern clearly. Across the US, from September 2025 to August 2026, "eye exam near me" drew about 246,000 searches a month through fall and spring, dipped to about 135,000 in June and July, and jumped to about 450,000 in January.
The spike is specific to exam searches. "Eye doctor near me," a broader search, stayed flat between roughly 450,000 and 673,000 all year. In our example market, Chicago, "eye exam near me" followed the national curve: about 12,100 in January against 6,600 to 8,100 in most months. Your market's numbers will differ, but the shape almost certainly won't.
There are smaller waves too. Searches for a pediatric eye doctor peak in September and October with the school year, and "eye doctor for pink eye" peaks in October. Each is worth a look when you plan the year, but none moves like January.
Why January: Many Vision Plans Count Exams by Calendar Year
Google doesn't tell advertisers why people search when they do, so treat any explanation as a reading of the evidence, not a fact. The evidence here is strong, though. Vision plans commonly allow one exam per calendar year, and their own documents say so:
- A Davis Vision plan summary lists the eye examination as covered "Once Every Calendar Year."
- One employer's VSP plan summary lists its exam as covered "Every calendar year."
- Anthem's individual vision plans advertise "Eye exams every 12 months or calendar year."
On January 1, every patient on a calendar-year plan gets a fresh allowance at once. Add New Year habits and it's easy to see why exam searches jump. Not every plan works this way: Visionworks, the optical chain, reminds customers that some plans reset at the end of an employer's fiscal year rather than the calendar year. So a practice with many patients from one large local employer may see a second, smaller bump in another month. Your own booking history will show it.
Isolation Runs on Bids You Set
Isolation, our name at BrandRocket for the exact-match campaign that protects the searches we know convert, uses manual bidding. With manual CPC, Google lets you name a ceiling for each click and never charges above it.
We set those bids at the ad group level, so every keyword in "routine eye exam" shares one bid and every keyword in "contact lens exam" shares another. The starting point is Keyword Planner's top-of-page range from Chapter 5, checked against what a patient is worth from Chapter 3. Then real auctions take over. After a week or two, the account's own numbers tell you which ad groups are getting top-of-page placement and which are priced out.
Make changes in small steps and give each one time to show up. Our habit is to adjust an ad group's bid once a week at most, by a modest amount, and to judge it on bookings rather than clicks. A bid that doubles your clicks on "eye exam near me" but adds no exams isn't a better bid. In January, when volume jumps, the same weekly rhythm holds; what changes is the budget, which comes next.
Impression Share Shows How Much of the Rush You Catch
Impression share measures the slice of eligible searches where your ad actually appeared. Google describes it as a way to see whether your ads could reach more people with a higher bid or a bigger budget. For an exam campaign, two more specific versions matter most. Search top impression share counts how often you landed in the group of ads above the results; search absolute top impression share counts how often you took the first slot outright.
On the searches that matter most, we aim for 75% to 90% search top impression share. Below that, you're missing patients who were ready to book. Much above it, you're usually paying for the last few percent at a steep price.
Google Ads breaks the missing share into two causes, and each one needs the opposite response:
- Rank means you were outscored in the auction, whether by bid, ad quality or landing page. Chapter 4 covers the quality side.
- Budget means your ad qualified but the day's money was gone. Raising bids here backfires: each click costs more, so the money disappears even earlier.
In January, the budget column is the one to watch.
Auction Insights Names the Chains Beside You in January
Auction insights shows who else is in your auctions. Google describes it as a way to compare your performance with the other advertisers taking part in the same auctions, using six statistics, including how often each one shows, how often your ads appear together, and how often each ranks higher.
For an optometry practice, the list is often dominated by retail chains. In our example market, every national optical brand we checked was running Google Search ads: LensCrafters, Pearle Vision, Target Optical, America's Best, Visionworks, MyEyeDr., Warby Parker and more. Many of them sell the exam as part of an eyewear business (Chapter 15 covers what that means for your offers).
The six numbers answer different questions. Impression share is how often each advertiser showed. Overlap rate is how often your ad and theirs appeared together. Position above rate is how often theirs sat above yours when both showed. Top of page rate and absolute top of page rate show how often each appears in the top ads and in the first slot. Outranking share is how often you ranked above them or showed when they didn't. Compare December with January: if a chain's impression share jumps in January, it's likely budgeting for the rush too, and you'll feel it in your own numbers.
You don't have to win every auction against them. If the cost of holding the top spot on a search climbs past what a patient from that search is worth, step back. Hold position on the searches your practice wins on, such as medical visits, children's exams and your own name, and let the chains pay for the rest.
Raise the Budget in December, Not Mid-January
The practical plan is simple, and the timing is the whole point:
- November: look back. If the account ran last January, pull impression share lost to budget for that month. That number is how much demand you left on the table.
- December: raise before the rush. Increase the daily budget on Isolation and the brand campaign before January 1, and check that the core exam ad groups can hold their target impression share at current bids.
- January: watch daily. Check impression share and budget pacing every morning for the first two to three weeks. If a campaign is limited by budget before midday, the afternoon's searchers are going elsewhere.
- February: step back down. Return budgets to normal as searches settle.
Remember that the front desk has to absorb the extra bookings too. Hold appointment slots for January, and make sure the phones are covered through lunch.
Exploration Bids Itself Toward the Target You Give It
Exploration, the broad-match campaign from Chapter 6, doesn't use manual bids. It uses target CPA. Google explains that you set the average cost per conversion you want, and it sets each bid based on how likely that search is to convert.
The target comes from Isolation's real cost per booking, not from a hope. Once it's set, hold it steady through January. Changing the target in the middle of the busiest month forces the bidding to relearn exactly when you need it stable. If Exploration needs to carry more January volume, raise its budget and leave the target alone.
Listen to the Calls Before You Raise a Bid
A higher bid that brings more calls isn't automatically a win. Before raising bids on any ad group, check what those calls actually were. Google's call reporting shows each call's length, and a front desk that notes whether an ad call booked an exam closes the loop.
In eye care, the calls to watch for are the ones that were never going to book: people asking about frame prices, whether you stock a certain contact lens, or looking for a surgeon rather than an optometrist (Chapter 4). A bid increase that buys more of those isn't growth. It's a more expensive way to answer the phone.
Next: Sell the Doctor
With bids and budgets set for the year, the next lever is the ad itself. Retail chains lead their ads with price. Independent practices have something the chains can't copy. Chapter 8 covers writing ads from what your patients already say about you, and why the doctor, not the frames, belongs in the headline.
Every chapter is on the guide's home page.
Every optometry client of our Google Ads management gets a December budget review booked months ahead. Doing it yourself? Pull last January's impression share lost to budget this week. It's the clearest number you have for next January.
