What is a good PPC cost?

Why a Universal 'Good' PPC Cost Doesn't Exist

If you've ever asked a marketing forum what a "good" PPC cost is, you've probably gotten five different answers — and the frustrating truth is that all of them are correct. A good PPC cost only exists relative to your industry, your conversion rate, and the value of a closed deal. Strip away that context, and the number is meaningless.

The averages look tidy enough. Cross-industry Google Search benchmarks cluster around $4.22–$5.26 per click and $53–$70 per lead. But those averages hide enormous spread. According to WordStream's benchmark research, "the biggest factor, however, is your industry" — and the range proves it. Ecommerce clicks average $1.16 while legal clicks run $6.75, with home services at $6.40 and real estate at just $2.37, per industry benchmark data.

Conversion rates swing just as wildly, which is where most benchmark comparisons fall apart. Dating sites convert at 9.64%, legal at 6.98%, and real estate at a measly 2.47% — meaning the same $5 click produces completely different economics depending on the vertical. As one aggregation of CPC research puts it, a $3 CPC with a 1% conversion rate is more expensive per lead than a $7 CPC with a 5% conversion rate. The click price tells you almost nothing on its own.

The math that actually matters:

• Cost per lead = CPC ÷ conversion rate — a $4 click at 3% conversion equals a $133 lead, per the formula-based framework
• Whether that lead cost is "good" depends entirely on whether the resulting acquisition cost fits your margins
• Deal value sets the ceiling — a $150 lead is trivial for a mortgage broker and catastrophic for a $200 ecommerce sale

Meanwhile, the ground is shifting under everyone's feet. CPCs rose for 87% of industries in 2025, averaging 10% higher year-over-year, and average CPC has nearly doubled from $2.76 in 2020 to $5.42, according to seven-year trend data. Yet 65% of industries saw conversion rates improve in the same period — higher costs, better economics. That's why chasing an arbitrary benchmark number is a losing game.

The mortgage industry illustrates this most vividly. Shared leads costing $10–$100 each typically produce $5,000–$10,000+ per funded loan, while exclusive leads at $30–$60 yield a blended cost of $1,200–$2,000, per analysis of 3.2M+ mortgage leads. The cheaper lead per-unit was dramatically more expensive per closed deal.

This is exactly why GrowthPros prices leads by niche and deal context rather than promising a universal number — a $25 auto lead and a $300 commercial mortgage lead can both be bargains, or both be overpriced, depending on what happens after delivery. Judge your costs against your vertical, your margins, and your close rate. Nothing else.

How Industry and Platform Shape Your PPC Economics

A $6.75 click and a $1.16 click can both be "good" PPC costs — depending on your industry. Benchmarks show legal pays roughly six times more per click than ecommerce, and neither number means much until you divide it by your conversion rate and deal value.

Industry is the single biggest driver of what you'll pay. Average CPCs on Google range from ecommerce at $1.16 to legal at $6.75, with real estate at $2.37, finance at $4.68, insurance at $5.88, and home services at $6.40, according to industry benchmark data. WordStream's own benchmark research confirms it plainly: "The biggest factor, however, is your industry."

Platform choice changes the picture just as dramatically. Google Search averages $5.26 per click with a cost per lead of $70.11, while cross-platform data shows Microsoft/Bing at $1.54 per click — roughly 40% lower — with an average CPL of $41.44. LinkedIn is the most expensive major platform at $5.58 per click, while Facebook's global median sits at $1.11 and Amazon Ads at $0.98.

Where does that leave you? A few practical anchors:

• Cross-industry averages cluster around $4.22–$5.42 CPC and $53–$70 CPL on Google Search — useful as a sanity check, not a target.
• Conversion rates swing widely by vertical: legal converts at 6.98% while real estate converts at just 2.47%, per PPC Chief benchmarks.
• A simple formula beats any benchmark: cost per lead equals CPC divided by landing page conversion rate, and it's "good" when the result fits your margins, as budget planning guidance puts it.
• Expect seasonal spikes: CPCs can climb 30–50% during peak periods like Q4 and holidays.

The deeper lesson is that the cheapest lead is rarely the cheapest customer. In the mortgage space, shared leads cost $10–$100 each but typically produce $5,000–$10,000+ per funded loan, while exclusive leads at $30–$60 yield a far better $1,200–$2,000 blended cost per funded loan, according to proprietary lead data. A worked B2B example tells the same story: a provider charging 2.7× more per lead delivered opportunities at 56% lower cost because of a 30% versus 5% lead-to-opportunity rate.

That's why GrowthPros prices leads by niche and delivers them exclusive or capped at two buyers maximum — because a cost is only "good" when the lead actually converts, and getting a qualified lead contacted within five minutes makes that far more likely. Whether you're running ads yourself or buying leads outright, judge your PPC economics by cost per closed deal, not cost per click.

What Actually Makes a PPC Cost 'Good': Speed, Quality, and Exclusivity

What actually makes a PPC cost 'good' isn't found in the sticker price of a lead—it's revealed in what happens after the click. A low-cost lead that sits untouched, gets buried in a shared inbox, or fails to convert because of slow follow-up often ends up costing far more per closed deal than a higher-priced alternative. True cost efficiency hinges on three factors: lead quality, exclusivity, and speed-to-lead.

Consider the mortgage industry, where data shows exclusive leads cost $30–$60 per lead but yield a blended cost per funded loan of $1,200–$2,000. In contrast, shared leads priced at $10–$100 per lead typically produce a cost per funded loan of $5,000–$10,000+. This isn't a typo—it's the math of quality. Exclusive mortgage leads achieve contact rates up to 65%, compared to roughly 25% for shared leads, making them 2.6× more likely to result in contact. When you factor in that a five-minute response is 21× more likely to qualify a lead than a 30-minute one, the value of immediacy becomes undeniable.

The same principle applies in B2B contexts. One example shows a provider charging 2.7× more per lead ($400 vs. $150) delivering opportunities at 56% lower cost ($1,333 vs. $3,000) due to a 30% vs. 5% lead-to-opportunity rate. Higher upfront costs only look expensive until you measure what actually matters: cost per closed deal. GrowthPros builds its model around this reality—delivering exclusive and capped-shared leads with AI-driven voice, SMS, and email follow-up inside a five-minute window, 24/7. Because contacting a lead within five minutes makes contact roughly 100x more likely than at thirty minutes, and about 78% of buyers choose whoever responds first, speed isn't just a nice-to-have—it's a revenue multiplier.

Lead quality, exclusivity, and speed-to-lead aren't just nice advantages—they're the levers that turn a seemingly expensive PPC cost into a profitable acquisition engine. When you judge cost by what it takes to close a deal—not just to generate a click—the equation flips. A higher CPL can still mean a lower CAC if the lead is more likely to convert, less likely to be chased by competitors, and engaged before interest fades. That’s how you stop buying leads and start buying outcomes.
