We audited a SaaS account last month spending $22K on Google Ads. After 90 minutes, we found $8,400 going to clicks that would never close. Same story we see almost every audit.
B2B PPC is brutal in a way B2C isn’t. Your sales cycle runs 90+ days. Six people sit on the buying committee. Half your “leads” are competitors, students, and job seekers. And Google’s algorithm — built to optimize for cheap conversions — actively works against you when an MQL is worth $5K and a closed deal is worth $50K.
Most accounts we inherit have the same seven leaks. Here’s how to find them and what to do about it.
1. Your conversion event is lying to you
Google optimizes toward whatever you tell it is a conversion. If that’s “form fill,” it’ll find you the cheapest form fillers on the internet — students, agencies pitching you, freelancers researching tools they’ll never buy.
The fix: stop optimizing for MQLs. Push SQLs and pipeline-stage events back into Google Ads as offline conversions. Connect your CRM (HubSpot, Salesforce) to Google Ads so when a lead becomes an SQL, the algorithm gets that signal — with the deal value attached.
The data backs this up hard. PPC leads convert to SQLs at roughly 26% on average, while SEO leads convert at 51%. The gap isn’t channel quality. It’s the signal you’re feeding the algorithm.
If you’ve never set this up, our walkthrough on Google Ads audience signals covers the audience-signal layer that pairs with offline conversions.
2. Performance Max is eating your budget
Google’s sales reps love Performance Max for B2B SaaS. We don’t. We’ve seen Pmax dump 70-80% of spend into Display and YouTube placements that look great in the dashboard and convert nobody.
Look at your asset group reports. If your Pmax campaign is generating 200 “conversions” but your sales team can’t remember the last deal that came from one — that’s the leak.
Either kill Pmax for lead gen and use Search only, or use Pmax with a tightly defined audience signal and exclude Display Network entirely. We wrote a full breakdown on whether Performance Max cannibalizes Search — short answer: yes, frequently.
3. Your keyword list is bloated and broad
Most B2B accounts we audit have 200+ keywords. Maybe 20 of them generate every conversion. The rest are spending money on traffic that will never become pipeline.
Two specific patterns we see constantly:
- Broad match without strong audience signals. Google reads “broad match” as permission to spend on tangentially related searches. We’ve seen accounts where “marketing automation software” matched to searches like “free marketing tools for students.”
- Bottom-of-funnel keywords missing. Most accounts bid on category terms (“CRM software”) and ignore the keywords with intent baked in (“alternatives to HubSpot,” “[competitor] vs [you],” “best CRM for 50-person sales team”).
Cut your keyword list by 60%. Add 15 high-intent long-tail terms. Watch CPA drop. The full framework lives in our keyword match types guide.
4. You have no negative keyword strategy
Run this query in your search terms report tomorrow morning: filter by spend > $50, conversions = 0. That list is your starting negative keyword list.
Standard negatives every B2B SaaS account should have on day one: “free,” “tutorial,” “course,” “salary,” “jobs,” “career,” “resume,” “internship,” “review,” “alternatives” (unless you’re targeting alternatives campaigns specifically), “open source,” “github.”
Industry data suggests accounts without negative keyword management waste a meaningful share of budget on non-converting search terms. We’ve seen audits where the wasted-spend percentage clears 40%.
Our negative keywords playbook goes deeper — including the negative keyword lists we apply day one to every new SaaS account.
5. Your landing page is generic
You’re paying $40+ per click and sending those clicks to your homepage. Or to a generic “Request a Demo” page that talks about your platform in 800 words of feature copy.
B2B PPC landing pages need three things working together:
- Message match. The headline mirrors the ad copy and the search query. If they searched “Salesforce alternative for small teams,” the headline says exactly that.
- One CTA. Single-CTA pages convert at 13.5% on average versus 10.5% for multi-CTA pages, per industry benchmarks.
- Social proof above the fold. A logo bar of customers in their ICP. One specific case study quote with a number in it.
Build a unique landing page per campaign — or per ad group, if budget allows. The framework is in our high-converting landing pages guide.
6. Branded search is hiding your real performance
Branded search converts at 15-30%. Non-branded converts at 1-3%. If you blend them in your dashboard, your CPA looks great — and you’ll never realize that 70% of your “Google Ads pipeline” is actually people who already heard about you somewhere else.
Split branded and non-branded into separate campaigns. Report on them separately. Then ask the harder question: of our non-branded spend, how much new pipeline are we actually generating? That’s your real Google Ads performance.
If the answer is “almost none,” you don’t have a Google Ads problem. You have a category-awareness problem — and paid search isn’t the right solve for that. LinkedIn or content might be.
7. You’re tracking clicks, not pipeline
The dashboards most B2B PPC managers send up the chain are full of clicks, CTRs, and CPCs. Nobody on the executive team cares.
Build the report your CFO actually wants:
- Spend
- Pipeline generated (not leads — pipeline, in dollars)
- Closed-won revenue attributable to paid search
- CAC and CAC payback period
- LTV:CAC ratio for paid-search-sourced customers
Calculate it monthly. If you can’t, your tracking infrastructure is the bottleneck — fix that before you touch a single bid.
What to do Every Monday morning
Open your Google Ads account. Run the search terms report. Filter by spend > $100, conversions = 0. Whatever you find there is your first hour of work this week.
If your account looks like the ones we’ve described — bloated keyword lists, Performance Max eating budget, optimizing for MQLs that never close, no offline conversion tracking — that’s the pattern we fix every week. As a B2B PPC agency focused on SaaS, we run a free audit that maps exactly where the leaks are.
