Google Ads Negative Keywords Every Accounting Firm Should Be Blocking

26 September 2026·6 min read

Quick answer: Every accounting firm running Google Ads should be blocking job-seeker terms ("accounting jobs," "resume," "cadetship"), DIY/software terms ("xero login," "myob login," "free tax calculator," "spreadsheet template"), student and course terms ("accounting degree," "TAFE"), and any service or location outside what you actually offer. Add these at the account level using a shared negative keyword list, then review your search terms report weekly for the first month and monthly after that. Negative keywords stop wasted spend on searches that were never going to convert — they won't fix a weak landing page or a low Quality Score, which are separate problems entirely. ✨

If you've never looked at your Google Ads search terms report, there's a good chance a meaningful slice of your monthly budget has gone to people looking for a job, a free calculator, or their Xero login page — not an accountant. It's one of the fastest wins available in paid search, and also one of the most commonly skipped, because it's not glamorous work 💖. Nobody gets excited presenting "we blocked 40 irrelevant search terms" to the partners, but it's often the single highest-leverage hour you'll spend on a campaign all quarter.

What most accounting firms get wrong

Setting the campaign up once with a handful of obvious negatives, then never opening the search terms report again.
Using broad match keywords with no negative list at all, which is close to handing Google a blank cheque against your daily budget.
Applying the same aggressive negative list to branded campaigns as to generic ones, accidentally blocking people searching for your own firm's name.
Adding negatives reactively one at a time instead of building a structured, reusable list that gets applied to every new campaign from day one.

The Accounting Firm Negative Keyword Starter List — build a shared list with these categories:

Job/career terms: jobs, careers, hiring, vacancy, salary, resume, cover letter, cadetship, internship, graduate program
DIY/software/login terms: free, template, DIY, xero login, myob login, quickbooks login, spreadsheet, calculator (unless you actually offer a free calculator tool), tutorial
Education/course terms: course, degree, diploma, TAFE, university, how to become an accountant, CPA exam
Out-of-scope service terms: any specific service you don't offer — e.g. "SMSF" if you don't do self-managed super fund work, "bookkeeping" if you're tax-only, "audit" if you outsource that
Out-of-area terms: suburb, city or state names outside your genuine service area, if you're a local practice rather than a remote/national one
Low-intent price terms: "cheap," "free consultation" (if you don't offer one), "no win no fee" style phrasing that doesn't apply to accounting services

Apply this as a shared negative keyword list at the account level so it automatically covers every new campaign, then layer campaign-specific negatives on top for anything unique to that campaign's offer.

Bayview Accounting & Advisory, Brisbane: A search terms audit found "accounting jobs Brisbane," "xero login," and "free tax calculator" had been quietly running for months, together accounting for a noticeable chunk of monthly ad spend with zero conversions attached to any of them. Adding a structured negative list reduced that specific category of wasted spend substantially within the first month — the campaign's overall conversion rate improved too, though that also reflected other changes made at the same time, so it wasn't purely the negatives doing the work.

Fernvale Bookkeeping & Tax, single-town regional practice: Added geo-negatives for every capital city plus service-scope negatives blocking "SMSF" and "audit," since neither is offered in-house. This mattered more for them than most firms because their entire budget was small enough that even a few irrelevant clicks a day represented a meaningful percentage of total spend.

Ferro Virtual CFO Services, commercial advisory firm: Blocked "cheap accountant," "free tax advice" and "basic tax return" — terms that were attracting high-volume, low-value price shoppers completely mismatched to a firm positioned around ongoing advisory work rather than one-off compliance jobs. Refining toward higher-intent commercial terms like "virtual CFO" and "business advisory accountant" shifted the lead quality noticeably, even though overall click volume dropped.

How to build and maintain your negative keyword list

Pull the search terms report weekly for the first month of any new or recently changed campaign — this is where the real waste hides, especially with broad or phrase match.
Categorise before you block. Group irrelevant terms into themes (job seekers, DIY, students, out-of-scope) rather than adding them one at a time — it's faster and catches variations you'd otherwise miss.
Use a shared negative keyword list at the account level for anything that applies across every campaign, and campaign-level negatives for anything specific to one offer or landing page.
Be careful with match type on negatives. A broad negative match can silently block legitimate traffic — "tax" as a broad negative could exclude "tax return help," which you actually want. Use phrase or exact match negatives where the term could have a legitimate meaning.
Revisit quarterly, not just at setup — your service scope changes, new competitor terms appear, and search behaviour shifts with the tax calendar.

💡 Negative keywords fix one problem, not all of them. They stop you paying for clearly irrelevant clicks — they won't rescue a campaign that's losing on Quality Score, a landing page that doesn't convert, or bidding that's simply too aggressive for your budget. Treat this as one lever in a proper account review, not a single fix for underperforming ads.

Mistakes to avoid

Over-blocking broad, genuinely high-intent terms like "accountant near me" out of an abundance of caution.
Applying your generic negative list to branded search campaigns and accidentally excluding people searching for your firm by name.
Setting negatives once at launch and never opening the search terms report again.
Blocking a term because it seems irrelevant without checking whether it's actually converting — some odd-looking search terms convert better than expected.
Forgetting to update the list when you add or drop a service line.

Frequently asked questions

Will adding negative keywords guarantee a lower cost per lead?

No — there's no guaranteed outcome here, and results depend heavily on your match types, competition in your area, and landing page quality alongside the negative list itself. What it reliably does is stop you paying for clicks that were never going to convert in the first place, which is a meaningful but not total improvement.

How often should we actually check the search terms report?

Weekly for the first month of any new campaign or major change, then monthly as a standing habit. Tax season search behaviour shifts enough that a quarterly-only review can miss several weeks of wasted spend.

Can we use the same negative keyword list across all our campaigns?

Mostly yes for the generic categories (jobs, DIY, students) via a shared list, but keep branded campaigns and service-scope negatives separate, since a negative that makes sense for a generic "accountant Brisbane" campaign can accidentally block valid traffic on a branded one.

Should we bother with negative keywords if our budget is already small?

Especially then — a small budget has less room to absorb waste, so even a handful of irrelevant clicks a day can represent a disproportionate share of total spend.
