Google Ads for B2B SaaS in 2026: what still works

If your Google Ads account is still optimized on form fills, you're paying for pipeline that never shows up in revenue. The 2026 playbook is simpler than the dashboards suggest — and it does compound.

The three levers that actually move ROAS

1. Intent depth over keyword volume. A campaign targeting "best CRM for [industry]" converts 4–6× better than a broad "CRM software" campaign, even with lower total traffic. Keyword volume is a vanity metric; keyword intent is a pipeline metric.

2. Negatives as a weekly cadence. Every account bleeds budget on irrelevant queries — students researching for papers, competitors doing reconnaissance, unrelated industries. A 30-minute weekly review of the Search Terms report and a disciplined negative-keyword list typically returns 15–25% budget efficiency inside a month.

3. Conversion events tied to closed-won. Google's Smart Bidding optimizes against the conversion events you give it. If those events are form fills, it optimizes for form-fillers. If they're SQLs, it optimizes for SQLs. If they're closed-won (via offline conversion import), it optimizes for revenue. The difference between tier 1 and tier 3 here is 2–3× in deal-quality-adjusted ROAS.

What to stop doing

• Broad match on new campaigns. Smart Bidding + broad match is a compounding budget incinerator on accounts without strong conversion data. Start exact + phrase, earn the right to broaden.
• Running the same ad copy for six months. Copy fatigue is real even on search — CTR drops ~8% month-over-month without iteration. Minimum viable cadence: 2 new RSAs per ad group per quarter.
• Optimizing on CPA alone. CPA with bad lead-quality signal is a lie. Tie it to downstream SQL→close rates or don't report it.

The weekly ritual that compounds

Fifteen minutes every Monday morning:

• Review Search Terms: add 3–5 negatives
• Check conversion action quality (what's firing, what's not)
• Review top spenders + any campaign with more than 30% spend change
• Flag one hypothesis to test this week

That's the whole thing. Everything else is decoration.

How we run it for clients

Every Google Ads account we operate goes through the same stack: offline conversion import from the CRM closed-won field, weekly search-term review automated via an n8n workflow that posts candidate negatives to Slack, and a Monday morning roll-up that lands in the CFO's inbox at 9:01 AM. No dashboard to log into. The number moves, the account learns, the budget defends itself.
