Three decisions make or break SaaS PPC: what you count as a conversion (a qualified account, not a sign-up), what you are willing to pay for one (worked back from plan price and retention), and which searches you buy (people comparing tools, not people learning the topic). Get those right and the platform settings are detail.
Nobody can promise a cost per account. The benchmarks below are medians across industries; your own numbers after 90 days are the only ones that matter.
What PPC does for a SaaS company, and what it does not
Paid search puts your product in front of someone who typed your category, a competitor's name or a problem your product solves, this minute. Paid social puts it in front of people who match a job title, an industry or a list of accounts. Both can bring trials this week, which SEO cannot. Both stop the moment you stop paying, which SEO does not.
Neither fixes the product or the website. A click lands on your pricing page or your sign-up flow, and whatever those do to visitors, they will do to paid visitors at full price. Our SaaS marketing page says it from experience: when ads are scored on sign-ups, the platform finds more people who sign up and leave. So the first job is to decide what counts as a conversion, and the second is to make sure the landing pages deserve the spend. Our guide to SaaS website design covers the pages.
What SaaS PPC costs: the figures that exist
WordStream's 2026 benchmarks, drawn from 13,474 US search campaigns between April 2025 and March 2026 and reported by ppc.land, put the median cost per click across all industries at $5.42, the median conversion rate at 8.18% and the median cost per lead at $66.69. The report covers 23 industries, and the article does not break out a software or SaaS category, so we quote none. These are market medians and not our prices.
Two things about software clicks follow from experience rather than from that study, so take them as working assumptions to test. Category and competitor searches in software are often bid up by well-funded rivals, so your click may cost more than the cross-industry median. And a “lead” in those benchmarks is a form fill, which for SaaS is a trial or a demo request, not a paying account; the step from one to the other is where most SaaS budgets are lost.
Work out what you can pay for a paying account
Do this arithmetic before you open an ad account. It is yours, and it is not a forecast.
Start with the monthly plan price and the gross margin on it. Multiply by the number of months a typical customer stays, or a conservative guess if you do not yet know. That is the gross profit of one account. Decide how much of it you are willing to spend to win the account; many teams aim to recover acquisition spend within the first year, which caps the spend at twelve months of gross profit or less. That cap is your maximum cost per paying account.
Now back into the funnel. If one trial in five becomes a paying account, you can pay one fifth of that cap per trial. If one visitor in twenty starts a trial, you can pay one hundredth of the cap per click. Compare that figure with the clicks your category is selling at. If the click costs more than you can pay, the fix is not a cleverer campaign; it is a better trial-to-paid rate, a higher plan price or a different channel.
How the Google Ads budget works
You set an average daily budget per campaign and can change it at any time. Google's help page on spending says a day can run up to twice that figure, the month is capped at 30.4 times the daily budget, and you are credited if the cap is exceeded. A $100 daily budget is therefore at most $3,040 in a month.
The same page explains Quality Score, a 1 to 10 estimate of how relevant your ad, keywords and landing page are to the search, where higher quality can lower the price and lift the position, and the two bidding routes: manual, where you set the most you will pay for a click, and automated, where Google bids toward a goal such as a number of conversions. Automated bidding learns from whatever you send it as a conversion, which is why the conversion definition comes first.
Which searches and audiences to buy
Buy the people who are choosing, and block the people who are learning or job-hunting.
- Category searches: “[category] software”, “[category] tool for [team]”, “best [category] software” where your pricing page can compete. These cost the most per click and bring the buyers closest to a decision.
- Alternatives and comparison searches: “[competitor] alternative”, “[competitor] vs [competitor]”. Send them to a fair comparison page, not the home page. Check each platform's rules on using a competitor's trademark in ad text, and keep it out of the headline.
- Integration searches: “[category] that integrates with [tool]”. Lower volume, very high intent.
- Problem searches with a software answer: “how to automate [task]”. Only where your landing page shows the product doing it.
- Brand searches: your own name, cheaply, so that a rival's ad does not sit above your result.
- Block: “free”, “open source”, “jobs”, “salary”, “course”, “tutorial”, “login”, “download crack” and the names of tools you do not compete with. Review the search terms report weekly.
On paid social, the equivalent of a keyword is the audience: job titles and functions that buy your category, company sizes that fit your plans, industries you serve, and uploaded lists of target accounts and of trial users who have not converted. Retargeting trial users with the one feature they did not reach is often the cheapest paid social a SaaS company can run.
Settings that stop a SaaS budget leaking
Five settings do most of the work:
- Define the conversion as a qualified account. Send the platform a trial that reached a first result, a demo that was held, or a paid plan, where your data and privacy rules allow it. Sign-ups alone teach the platform the wrong lesson.
- Match the landing page to the search. A category search lands on the category or pricing page; a competitor search lands on the comparison page; an integration search lands on the integration page. The home page is for brand searches.
- Target the countries you sell in and support. Time zones, currencies and data rules decide this, not the size of the audience.
- Separate brand from non-brand. Brand campaigns look cheap and make everything else look better than it is. Report them apart.
- Set a learning period before you judge. Automated bidding needs conversions to learn from; a campaign scored on paid plans may get only a few a month. Judge on 90 days.
What to expect in the first 90 days
Weeks one to four collect data: clicks arrive on day one, trials within days, and the first paying accounts only after your trial length has run. Weeks five to eight cut the searches and audiences that spend without trials, and move budget toward the ones that produce qualified accounts. Weeks nine to twelve give the first readable cost per paying account, which is the number the whole program is judged on.
A fair monthly report shows spend, clicks, trials or demos, qualified accounts, paying accounts, cost per paying account, and what was changed and why, with brand and non-brand apart. A report that shows clicks and sign-ups and stops there is a warning. Nobody can promise a cost per account, and we give no figure in advance; the arithmetic above is the honest guide.
When PPC will not pay back for a SaaS company yet
Fix these first, or the spend tells you nothing:
- The trial-to-paid rate is low or unknown. Ads buy trials at full price; if few become customers, the spend teaches you nothing you could not learn from organic trials first.
- The plan price cannot carry the click. Low-priced self-serve plans in expensive categories rarely pay back on search; content, integrations and partnerships may suit them better.
- The pricing page confuses people. Fix it before you send paid traffic to it.
- You cannot track to a paid plan. Without that link, every optimization is guesswork.
