It is the Tuesday after the October extension deadline. The managing partner of a six-person CPA firm finally has a quiet hour. A proposal is open on her screen from an agency that promises to "dominate local search for accountants," at a monthly retainer. Beside it is a note from her office manager saying that most of this year's new clients came from two referral sources and one chamber of commerce lunch. She has to reply by Friday. The question underneath is not whether to market. It is whether she knows where her good clients came from, because that decides whether the retainer is a smart bet or an expensive guess.
Most small firms face the same moment, usually right after a busy season, when memory of what worked is fresh and the budget conversation is open. This page walks through how to use that moment: what to look at first, what search can realistically do for a CPA firm, how to test one channel without betting the practice, and where paying an outside team is a reasonable choice.
Start with the clients you already like
Pull your last year of new engagements and sort them by how happy you are to have them, not just by fee. For each one, write down how they found you: a referral from a lawyer or banker, a current client, a Google search, a networking event, or "I don't know." Ask the client if the file doesn't say. A short call works better than guessing.
This list is your real marketing report. It shows which source brings in the work you want, whether that is business owners who need ongoing advisory, landlords, or people with messy multi-state returns. It also shows how many entries say "I don't know," which tells you how much of your marketing you can currently see.
Choose a client you want more of
"Marketing for CPA firms" is too broad to act on, because a firm that does payroll for restaurants and a firm that handles estate returns have different buyers. Write one sentence naming who you serve and what problem they have when they call you. A dental practice owner who is behind on bookkeeping and worried about an audit is a specific person. "Small businesses and individuals" is not.
That sentence shapes everything after it: the page on your website that a referral source will look at, the topics you choose for email, and the search terms worth paying for, if you pay for any.
How much search is out there for this
Be realistic about the size of this pool. The whole cluster of searches around marketing for CPA firms, 28 distinct phrasings merged together, adds up to about 150 searches a month. Interest is seasonal. It peaked at 90 a month in March and dropped to 30 a month in January. Those searches are mostly made by people in your own profession looking for ideas, not by the business owners you hope to win.
What a paid click can cost
If you want to test paid search, the highest top-of-page bid advertisers pay for this topic is $8.43 per click. That is a ceiling for the most competitive terms, not what you will pay on average, and it varies by search phrase and location. The point is that a handful of clicks isn't expensive to buy, but clicks are not clients. What matters is how many calls come from them, how many become engagements, and what an engagement is worth over several years.
| Channel | What it is good at | What to watch |
|---|---|---|
| Referral partners (attorneys, bankers, planners) | Warm introductions to clients who already trust you | Whether you ask for introductions, not just wait for them |
| Your own client list by email | Reminders, deadlines, and added services to people who already pay you | Replies and booked calls, not opens |
| Google Business Profile and reviews | Showing up when someone nearby looks for an accountant | Review count and whether the phone rings |
| Paid search | Fast tests aimed at a narrow service | Cost per booked consultation, not cost per click |
| Local networking and events | Relationships in one industry or town | Follow-up within a week of each event |
Run one test and keep score
Pick one channel and one service. For example, run a small paid search campaign for one service in your own metro area for a few weeks, or send a short email series to current clients about a service they don't use yet. Decide beforehand what counts as a result: a booked consultation, a signed engagement letter, a referral from a new source.
Then make sure you can trace the result. Calls, form fills, and booked meetings should be tagged to their source, and your intake sheet should have a "how did you hear about us" field that someone actually fills in. Without that, you will end the test with the same uncertainty you started with.
Judge the test before the next busy season
Because demand rises toward spring, there is a built-in calendar. Use the quiet months to set things up, and use the busy ones to collect results. When the test period ends, compare what you spent, including your own hours, to what signed work came out of it. If you can't connect the two, fix the tracking before you spend more.

Where outside help fits, and where it doesn't
You don't need an agency to ask clients how they found you, or to write down your best-fit client. Those are your jobs. Outside help makes sense when you have decided to run paid search and want the account built and managed correctly, when conversion tracking is broken or missing and you can't tell which calls came from ads, or when you want a second opinion on an existing campaign before renewing it.
A good partner will ask for your client list and your numbers first, will tell you if search is too small a pool for your market, and will give you access to the account in your own name. If a proposal skips those steps and goes straight to a retainer, treat that as an answer to your Friday question.
