Published B2B SaaS Google Ads CPC figures are almost always a single blended average across every category, which is the least useful shape the data can take. Across 18 B2B software categories the estimated cost of a click runs from $3 to $112, a spread of roughly 37x.
This is the companion to the cybersecurity CPC benchmarks, using the same method on the wider B2B software market. The headline comparison is worth stating up front: B2B software is dramatically cheaper per click than cybersecurity, and that is not the advantage it appears to be.

How these numbers were produced
Google Keyword Planner returns a top-of-page bid range, which is an estimate of what you would need to bid, not what anyone paid. Actual CPC generally lands below it, so publishing the raw estimate would misrepresent the market.
So the estimates are calibrated against real spend. Across 5 B2B accounts I manage, I took every keyword with 30 or more clicks over 90 days, compared its actual average CPC to Google’s estimate for the same keyword text, and derived the ratio. 249 keywords matched.
Non-brand keywords paid a median 56% of Google’s high top-of-page estimate. Brand keywords paid 17%, because Quality Score rewards the tight match between a branded search, a branded ad and a branded landing page. Everything below uses the non-brand figure, since category terms are non-brand by definition.
The full method, including why the brand split matters more than any single number, is in the cybersecurity benchmarks post.
B2B software CPC by category
18 categories, US, English, Google Search. Estimated actual CPC is Google’s high top-of-page bid multiplied by 0.56.
| Category | Searches/mo | Google high bid | Estimated actual CPC |
|---|---|---|---|
| Contract management / CLM | 3,600 | $32 – $200 | $18 – $112 |
| HR software | 12,100 | $15 – $108 | $9 – $61 |
| Expense management | 3,600 | $28 – $101 | $16 – $56 |
| HRIS | 3,600 | $13 – $100 | $7 – $56 |
| Customer support / helpdesk | 1,900 | $23 – $100 | $13 – $56 |
| ITSM | 3,600 | $33 – $90 | $19 – $50 |
| Subscription billing | 320 | $30 – $84 | $17 – $47 |
| Applicant tracking | 12,100 | $8 – $69 | $5 – $39 |
| Project management | 135,000 | $9 – $62 | $5 – $35 |
| CRM | 165,000 | $7 – $55 | $4 – $31 |
| eSignature | 8,100 | $7 – $55 | $4 – $31 |
| Revenue intelligence | 90 | $20 – $55 | $11 – $31 |
| Marketing automation | 2,400 | $15 – $51 | $9 – $29 |
| APM | 2,900 | $17 – $47 | $10 – $26 |
| Observability | 1,600 | $18 – $46 | $10 – $26 |
| Business intelligence | 8,100 | $10 – $43 | $6 – $24 |
| ERP | 49,500 | $6 – $38 | $3 – $21 |
| Data warehouse | 880 | $6 – $30 | $4 – $17 |
Total volume across those 18 terms is roughly 414,000 searches a month, against 70,000 for the 15 cybersecurity categories. Six times the demand at a fraction of the price.
Why the cheap categories are the hard ones
The obvious reading of that table is that B2B software is an easier place to buy traffic than cybersecurity. The obvious reading is wrong, and understanding why is the most useful thing here.
Cheap clicks in a mature category mean the category has already been won. CRM at $4 to $31 with 165,000 monthly searches is not an opening. It is a market where Salesforce and HubSpot have spent two decades making “CRM software” a branded decision before anyone types it. The click is cheap because the searcher is usually comparison-shopping between two names they already trust, neither of which is yours.
Contrast pentest in security at $123 to $189. Expensive, but the category is unsettled and a well targeted newcomer can genuinely win the click.
Price reflects competition for the click, not difficulty of the sale. What you pay is set by Ad Rank against the other bidders, which says nothing about what happens after. ERP at $3 to $21 across 49,500 searches looks like the bargain of the dataset. It is also a category with 12 to 18 month sales cycles, procurement committees of ten or more, and implementation costs that dwarf the software. A cheap click into a two-year sales process is not cheap acquisition.
The expensive B2B categories are expensive for the same reason the expensive security ones are. Contract management at up to $112 tops this table because legal software buyers have urgent, deadline-shaped problems and high contract values, the same dynamic driving pentest prices. Expense management, HRIS and ITSM cluster in the $50s because those are operational purchases with clear budget owners and short evaluation cycles.
The pattern across both datasets: price tracks buyer urgency and deal value, not category size.
Why the five most expensive categories cost what they do
The top of this table has a pattern, and it is not the one most people expect. None of these are the biggest categories. All five involve a buyer with a deadline, a budget line, or a contract value that justifies an expensive click.
Contract management / CLM: $18 to $112
The widest range in the dataset, and the top end is nearly 4x the next category’s floor. Legal software buyers arrive with a specific, dated problem: a renewal cycle, an audit, a general counsel who has decided that contracts living in email is a risk the board should hear about.
Contract values are also high and renewals are sticky, which means a customer acquired here is worth years of revenue. Bidders can rationally pay three figures for a click and still clear payback.
The enormous spread from $18 to $112 tells you the category head and its long tail behave very differently. That is the clearest invitation in this table to bid on specific problem terms rather than the category name.
HR software: $9 to $61
Volume and price both high, which is unusual. 12,100 searches a month at up to $61 makes this the busiest expensive category here.
The reason is fragmentation. Unlike CRM, there is no two-vendor default in HR software, so a genuine evaluation happens on most searches and more bidders think they can win it. Buyers also tend to have a clear budget owner and a compliance-shaped reason to move, which shortens the cycle relative to ERP.
Expense management: $16 to $56
A solved problem with an obvious owner. Finance leaders know what expense management is, know they need it, and can usually authorize the purchase without a committee.
That combination of clear need, clear owner and short evaluation produces reliable conversion, and bidders price accordingly. Low drama, consistently expensive.
HRIS: $7 to $56
The floor is the interesting number here. At $7, the bottom of this range is among the cheapest in the dataset while the top reaches $56, an 8x spread inside one category.
That usually signals a category where the terminology is unsettled. “HRIS” means different things to different buyers, so some queries carry real purchase intent and others are people working out what the acronym covers. Precision in match type matters more here than in almost any other category in this table.
Customer support / helpdesk: $13 to $56
Lower volume than you would expect at 1,900 searches a month, and priced near the top of the table anyway.
Support software sits close to revenue, since bad support costs customers directly, so the purchase gets urgency that its modest search volume does not suggest. It is also a category where switching happens after a specific bad experience, which produces buyers who are already decided and just choosing.
What the volume tells you that the price does not
Three categories in this dataset carry volume that changes what a strategy should look like.
CRM at 165,000 and project management at 135,000 are effectively consumer-scale search markets. At those volumes, a category head term is a branding expense with a conversion rate attached, not a performance channel. Nobody at Series A should be bidding “crm software” broadly.
ERP at 49,500 with a $3 floor is the clearest trap in the table. Enormous volume, almost free clicks, and a sales cycle long enough that your attribution window will expire before the deal closes. Accounts that chase this volume produce impressive lead counts and unimpressive pipeline.
Revenue intelligence at 90 searches a month is the opposite problem and worth including precisely because it is unglamorous. A category can be real, well funded and commercially live while having almost no search demand at all. Paid search is the wrong first channel for a category nobody knows to search for yet, and no amount of budget fixes that.
If your category sits below roughly 500 monthly searches on its head term, the honest read is that search is a capture channel for you rather than a demand channel, and your growth has to come from somewhere else first.
That is not a reason to skip paid search entirely. It is a reason to size it honestly. A capture channel should be small, tightly targeted at the few hundred people who do search, and judged on whether it catches the buyers your other channels created rather than on how many leads it generates on its own. Companies get this wrong in both directions: some ignore search until a competitor owns their category name, and others pour a demand-generation budget into a channel with no demand to generate.
B2B software against cybersecurity
Putting the two datasets side by side:
| Cybersecurity | B2B software | |
|---|---|---|
| Categories measured | 15 | 18 |
| Estimated actual CPC range | $20 – $189 | $3 – $112 |
| Total monthly search volume | ~70,000 | ~414,000 |
| Most expensive category | Pentest / PTaaS | Contract management |
| Cheapest category | Zero trust / SASE | Data warehouse |
Cybersecurity is roughly 3x more expensive per click and roughly 6x smaller. That is a difficult combination, and it explains why so many security founders conclude paid search does not work: they are entering a small, expensive auction, usually at the head term, usually with a budget sized for a category that behaves nothing like theirs.
It also explains why security rewards precision more than any other B2B vertical. When clicks cost $150 and volume is thin, the negative keyword layer and the conversion tracking stop being hygiene and become the whole strategy.
What this means for a budget
Take the same $6,000 monthly budget across both markets.
In CRM at $20 a click, that is 300 clicks into a category where the searcher has probably already decided between two incumbents.
In contract management at $80, it is 75 clicks into a category with urgent buyers and high contract values.
In ERP at $12, it is 500 clicks into a 12 month sales cycle your reporting will lose track of.
The click count is the least important number in that comparison. What matters is whether the searcher can decide, whether they can decide within your reporting window, and whether you can be a genuine candidate when they do.
Two moves apply across every category in this table. Bid on comparison, alternative and requirement terms rather than category heads, since they cost a fraction and sit closer to a decision. And connect your CRM back to your ad account so bidding optimizes toward qualified opportunities rather than form fills, which matters more as sales cycles lengthen. I covered why in what is cost per MQL.
What I am not claiming
These are calibrated estimates, not measured CPC per category. The calibration is real and measured across 249 keywords. Applying it to each category is an inference.
The calibration came from 5 accounts in legal, tax and healthcare-information software. Those are B2B software accounts, which makes this a closer fit than for the cybersecurity post, but auction dynamics still differ by category.
One seed term per category. The cybersecurity dataset used two or three per category; this one uses one, so the ranges are narrower and less robust. Treat the ordering as more reliable than any individual figure.
US, English, Google Search only. Microsoft Ads generally runs cheaper in B2B and is not described here.
Common questions
Why is CRM cheaper than HR software?
Almost certainly because CRM is a solved category in the searcher’s mind. Volume is enormous but the decision is usually between two known brands before the search happens, so the marginal click is worth less to a bidder. HR software has more genuine vendor fragmentation and more undecided buyers, which bidders will pay more to reach.
Should I bid on my category head term at all?
If your category has under about 5,000 monthly searches and your product is genuinely differentiated, often yes. Above roughly 50,000 searches with entrenched incumbents, rarely as a first move. The comparison and alternative terms around the head almost always price better and convert closer to a decision.
These are lower than my actual CPC. Why?
Most commonly because your account is matching broader than you think. A broad match keyword on a cheap head term can pull in adjacent, more expensive auctions. Check your search terms report against what you believe you are bidding on before concluding the benchmark is wrong.
Which of these categories suit Microsoft Ads?
Broadly, the ones selling to older, larger, less technical organizations. Microsoft’s search share skews toward desktop, Windows and corporate environments, which maps well onto ERP, ITSM, HRIS and expense management, and maps poorly onto developer-adjacent categories like observability and APM.
The auction is also thinner almost everywhere, so clicks typically cost less than the figures above and cost per qualified opportunity often comes out better. The trade is volume: you will not replace Google, you will supplement it. For a category priced at the top of this table, a channel running materially cheaper is worth testing before you conclude paid search does not work for you.
How often do these change?
Enough that I re-pull quarterly. Funding events move a category’s prices within weeks, since a newly funded competitor with a growth target bids differently than an established one.
