How do you run Google Ads for a B2B SaaS product?

Focus on high-intent, problem-aware keywords. People searching for your category are already sold on the solution — your job is to win that moment with tight ad-to-landing-page relevance and frictionless trial signup flows.

What's a good payback period for B2B SaaS paid acquisition?

Under 6 months is the benchmark for healthy growth. A 2.89-month payback period — like in this case study — means the channel is highly capital-efficient and ready to scale.

How do you calculate MRR attributed to Google Ads?

By passing trial start events as conversion actions, then matching closed accounts back to their originating campaign through CRM data. Combining first-touch and assisted attribution gets you close to the real number.

Can early-stage SaaS companies run profitable Google Ads?

Yes — if the product has clear search intent. If people are actively searching for what you do, Google Ads can be profitable from month one. If you're creating a new category, you'll need to build awareness first.

B2B AI SaaS Case Study: $2,219 in New MRR in 30 Days with a 2.89-Month Payback

This case study covers a Google Ads engagement for a B2B AI SaaS company that generated $2,219 in new monthly recurring revenue within the first 30 days of active management, with a customer acquisition payback period of 2.89 months. For a B2B software product, a sub-3-month payback period on paid acquisition means the channel is genuinely capital-efficient and ready to scale with confidence — every dollar spent on acquisition is recovered and generating profit in under a quarter. The strategy centered on high-intent search queries: terms used by potential customers who are actively aware they have the problem the product solves and are evaluating solutions, rather than broader awareness-stage keywords that generate impressions but rarely drive direct trial signups. The campaign architecture was deliberately tight in the first 30 days — a small number of tightly themed ad groups, exact and phrase match keywords only, aggressive negative keyword coverage to prevent irrelevant spend, and a single conversion action (trial signup) as the optimization target. This narrow focus allowed Smart Bidding to accumulate clean, unambiguous signal quickly rather than spreading conversion data across a fragmented account structure.

The conversion tracking setup was a non-trivial part of this engagement's success. Many B2B SaaS companies run Google Ads campaigns optimized against a generic form submission event that captures everything from trial signups to newsletter subscriptions to contact form inquiries — all of which have radically different downstream value. By working with the client to identify the exact event that correlated most strongly with eventual paid conversion (in this case, a specific onboarding step completion rather than the signup itself), the campaign was optimized against a signal that actually predicted revenue, not just activity. The Google Ads account then had MRR data imported back as offline conversions at the point of subscription, giving the algorithm a direct revenue signal to optimize against. The result was a feedback loop where the algorithm progressively favored the queries and audiences most likely to produce paying subscribers — which is what made the 2.89-month payback achievable rather than theoretical.
