A client came to us with a Google Ads account that, on the surface, looked like it was doing fine. All-time blended cost per lead sat at $8.78 across roughly $4,600 in spend and 523 leads. That number alone doesn’t scream “problem.” It’s the kind of figure a lot of accounts would report to a client without a second look. Breaking it down by campaign, and by what was still active versus what had already been paused, told a very different story.
The Setup
The account’s full history included campaigns run across several markets over time, some of which had already been paused after underperforming: $2,341.81 spent for just 7 leads before the client cut them off. That history alone was dragging the all-time blended CPL up to $8.78.
But the story didn’t end with what had already been paused. The four campaigns still active, aimed at generating leads for a B2B software product across two markets, told us there was more to fix. Combined, those four had spent just over $2,200 and generated 492 leads, for a blended CPL of $4.52. Better than the all-time number, but still hiding something underneath it.
Worth noting: one of those four, the retargeting campaign, didn’t exist when we took over the account. We built it as part of restructuring the setup, alongside the Demand Gen campaigns. It turned out to be the best-performing channel in the entire account, which is exactly why breaking performance apart by campaign mattered so much here. A blended view would never have shown us that the newest addition was quietly outperforming everything else.
The problem with blended numbers is that they average away exactly the information you need, and they do it at every level: the whole account, and even within what’s currently “active.”
The Diagnosis
Breaking the four active campaigns down individually is where the real picture showed up:
| Campaign | Spend | Leads | Cost per Lead |
|---|---|---|---|
| Retargeting | $285 | 332 | $0.86 |
| Branded Search | $641 | 151 | $4.24 |
| Demand Gen (Market A) | $625 | 3 | $208.27 |
| Demand Gen (Market B) | $672 | 6 | $112.00 |
Two campaigns, responsible for 98% of the leads generated by currently active spend, had used 42% of the budget. The other two, responsible for 2% of the leads, had used 58% of it. Both Demand Gen campaigns had been live for a full month with consistent daily delivery, so this wasn’t a case of “give it more time.” A month of real spend had already answered the question, and it echoed exactly what happened with the campaigns paused earlier in the account’s history.
We also checked conversion rate rather than just cost, since a low-volume campaign can sometimes hide a decent rate behind a small sample. It didn’t hold up here either. Branded Search converted at 8.17% of clicks. Both active Demand Gen campaigns converted under 0.3%. That’s not a pricing problem, it’s an intent problem: the traffic itself wasn’t interested, and no amount of bid or budget tweaking fixes that on its own.
One more detail mattered before making a final call: could the retargeting campaign’s strong numbers actually be borrowing credit from Demand Gen, if someone clicked a Demand Gen ad, didn’t convert, and later converted after seeing a retargeting ad? We checked the retargeting audience source and the relative traffic volumes involved. Demand Gen’s click volume was a fraction of the site’s total traffic, and its own poor conversion rate was weak evidence that it was sending genuinely engaged visitors into a remarketing funnel. The numbers held up.
The Fix
We recommended three moves, in this order:
- Pause both active Demand Gen campaigns. A month of consistent spend at over $100 and $200 per lead, in a channel that had now failed the same way across multiple markets and multiple attempts, was enough evidence to call it for good.
- Redirect the freed budget to Branded Search first. The campaign was flagged by Google Ads as limited by budget, meaning it was converting at $4.24 per lead and simply running out of daily spend before running out of demand. This was the highest-confidence move available: proven performance, capped only by budget.
- Scale retargeting incrementally, not aggressively. At $0.86 per lead it was the clear standout, but a retargeting audience is finite. You can’t 10x the budget and expect the same efficiency from a pool of people who’ve already visited the site. We recommended small, monitored increases instead of a lump reallocation.
The Result
Reallocating the roughly $40 a day previously spent on the underperforming Demand Gen campaigns into the two proven channels, while holding total budget flat, projected blended cost per lead among active campaigns dropping from $4.52 to approximately $1.92.
Set against the account’s full all-time blended CPL of $8.78, that’s a 78% reduction, with no meaningful drop in total lead volume. The campaigns being cut, both the ones paused earlier in the account’s history and the two identified in this audit, were never carrying meaningful volume in the first place.
No new budget. No new creative. No new targeting strategy. Just the discipline to stop looking at the account average and start looking at what was actually happening underneath it, at every level the account could be sliced.
Blended metrics are useful for a quick pulse check, but they’re a terrible place to make decisions from, and the risk compounds over time. An account’s all-time average can look acceptable while quietly carrying the cost of past experiments that didn’t work, and its current “active” average can look acceptable too, while a couple of efficient campaigns cover for one or two that are quietly repeating the same mistake. If you haven’t broken your own account down by campaign, and by what’s currently active versus historical, in the last month, that’s usually the fastest place to find money you’re already spending but not seeing a return on.
