Optometry Marketing: Count Exams and Optical Sales Apart

An optometry practice sells twice in one visit: the exam, then the glasses or contacts. You can judge your marketing once you see, for each source of patients, how many exams were kept and how many of those patients bought in your optical.

Quick answer

Pick last month and list every kept exam with the source that booked it: Google ad, Google Maps, vision plan directory, recall reminder, referral, walk-in. Next to each, mark whether that patient bought glasses or contacts, and the amount. Per source, divide spend by kept exams, then divide patients who bought by kept exams. Two numbers per source, read monthly: cost per kept exam and optical capture rate (the share of exam patients who buy from you).

What are you really paying for with one new patient?

One exam booking can lead to three streams of money: the exam itself (billed to a vision plan, medical insurance or the patient), the glasses or contacts, and the reorders or yearly return that follow. A report that counts bookings stops at the first and calls it a lead.

The cheap-to-get patient is not always the valuable one. A source that books many exams from people who take the prescription elsewhere looks good on a booking count and thin on the optical shelf. A smaller source with a higher capture rate can be worth more per exam.

If the booking tool and point-of-sale system do not share a patient number, ask the vendor how to match a purchase to an exam. A spreadsheet with a patient ID in both columns is a fair start.

Which searches bring exam patients, and what makes them book?

The figures are Google Ads Keyword Planner estimates for the US, October 2026. CPC is the cost per click. Both price columns are national, so treat them as context for your town, not a quote.

Two of those searches, "eye exam near me" and "contact lens exam", name the appointment itself. Send those ads to a page where a time can be picked, not to the home page.

The searcher then has two questions: do you take my vision plan, and can I book tonight. Answer both on the first screen of the page the ad opens. Patient scheduling software covers what an online booking tool should do, including keeping the ad source of each booking.

How should an insurance page be written?

Vision plans and medical insurance are not the same thing. A vision plan is a separate benefit usually built around routine eye care and eyewear, while medical insurance deals with eye disease and other medical problems. Which visit your office bills to which, and what each plan covers, is for your biller to state, not for the website to guess.

Write the page from your own billing list. Name each plan you accept, one per line, with the date you last checked it. Tell the patient what to bring: the plan card and photo ID, the old glasses or contact lens box, and a list of medicines. Say plainly which kinds of visits you bill to medical insurance, and what you will do if a plan is not on the list.

If a plan lapses from your list, take it off the page the same day. Otherwise a patient books under that plan, fills a chair, and cannot be billed the way either of you expected.

What does the prescription rule change about the optical sale?

Two US federal rules from the FTC decide what happens at the end of the exam; neither applies in Canada. Under the Contact Lens Rule, the prescriber must give the patient a copy of the prescription at the end of the fitting, even if not asked, and a prescriber who sells lenses or has a financial interest in their sale must ask the patient to sign a statement confirming receipt (FTC contact lens guidance, checked 2026-10-15). It also says a prescriber cannot require a purchase, a fee or a waiver in exchange for the prescription.

The Eyeglass Rule works the same way for glasses: give a copy right after a refractive exam, before offering to sell glasses, with no extra fee and no purchase required. If you sell glasses, you ask for a signed confirmation of receipt, or send the prescription digitally after the patient agrees in writing to that method (FTC Eyeglass Rule guidance, checked 2026-10-15). The amended rule took effect September 24, 2024 (Federal Register, checked 2026-10-15), and both rules have you keep confirmations for at least three years. This is not legal advice and I am not a lawyer.

The patient leaves with the prescription and can buy anywhere. Your capture rate is earned by the frame selection, the price talk and the follow-up, and it is worth measuring on its own line.

How do recalls and reorders add revenue without ad spend?

A recall is a reminder that a patient is due: the annual exam, or a contact lens refill. These patients already know you, so the cost to reach them is a message, not an ad click. Count them separately as "recall exams kept" so they do not hide inside the new-patient numbers.

Settle consent before the first text. The FCC says an autodialed text to a mobile phone needs the owner's prior consent, written for commercial texts and possibly oral for informational ones (FCC, checked 2026-10-15). In Canada, CASL covers texts and emails: a commercial message generally needs express or implied consent, and it must name the sender and carry an unsubscribe mechanism (CASL, section 6, checked 2026-10-15). Timing and what to count per reminder are in patient appointment reminders.

What does a month look like with the numbers filled in?

Illustrative: every number below is made up for an imaginary two-chair optometry practice, and none comes from a client. Say an exam is billed at $120 on average, and the optical sells what the table says.

Now the formulas, per source.

• Google Ads: $2,400 / 30 kept = $80 per kept exam. 21 / 30 = 70% capture. $6,300 / 21 = $300 average sale. Value per kept exam: (30 x $120 + $6,300) / 30 = $330.
• Vision plan directory: 11 / 22 = 50% capture. $2,750 / 11 = $250 average sale. Value per kept exam: (22 x $120 + $2,750) / 22 = $245.
• Recall reminders: 14 / 18 = 78% capture (rounded). $4,200 / 14 = $300. Value per kept exam: (18 x $120 + $4,200) / 18 = $353 (rounded).

The directory keeps 88% of its bookings (22 of 25) at no ad cost, but half of its patients leave without buying, so its kept exam is worth $245. The ads cost $80 per kept exam and bring a patient worth $330.

How do I send exams and optical sales back to Google Ads?

An ad account can only learn from what it is told. Tell it two things as separate conversion actions: "Exam kept" with the amount you collect for the exam, and "Optical sale" with the actual sale amount. That gives bidding a reason to favor clicks that turn into patients who also buy.

The sale amount comes from your point-of-sale system, so it arrives days after the click. Matching it back needs the click identifier (GCLID) that Google adds to the ad link, saved with the booking. The reasoning on what number to attach is in what value to send with offline conversions, and how primary actions add up explains why two primary actions for one patient land in one combined Conversions total.

Send nothing that identifies the patient to the ad platform. The upload needs the click identifier, the conversion name, the time and the value, not a patient name or a diagnosis. I do patient conversion tracking for an NYC medical practice in a HIPAA-conscious way; for optometry I have no clients, so this is how I would set it up, not what a practice achieved.

What should you ask a marketing agency?

• Which conversion actions feed the account, and is a booked exam counted the same as a kept one?
• Can you show cost per kept exam by source, not cost per lead?
• Who matches optical sales to the exam, and from which system?
• How do you keep patient details out of the ad platform?
• Which advertising rules apply to my offers? In Ontario, the College of Optometrists of Ontario's advertising guidelines (effective December 13, 2024, checked 2026-10-15) count a practice website as advertising and bar testimonials and superlative or comparative claims; in the US, each state board sets its own rules.
