The Speed-to-Lead Benchmark: how fast local service businesses respond to leads

Every local service business pays to generate leads — then loses a large share of them to a single, fixable problem: they answer too slowly, or not at all. To size that problem, we compiled the most credible published research on lead response time — from Harvard Business Review, MIT, Gartner, and the U.S. Census Bureau — and re-synthesized it for the local service economy. The numbers are worse than most owners think, and they have barely moved in over a decade.

This study pulls together several independent datasets, states plainly how they were combined, and lists the widely-circulated numbers we refused to use because we couldn’t trace them to a real source. You can read the methodology and check every source before you cite anything here.

Finding 1: The average business takes 42 hours — and one in four never answers

The foundational dataset is still the strongest. In The Short Life of Online Sales Leads, Harvard Business Review audited 2,241 U.S. companies, measuring how long each took to respond to a web-generated inquiry. Among the companies that responded within 30 days, the average first response took 42 hours. Only 37% responded within an hour. And 23% never responded at all.

That study is from 2011 — and its age is precisely the point. Independent “mystery-shop” audits in the years since, in which researchers submit real inquiries and time the replies, have repeatedly found the same shape: a small fraction reply fast, most take hours or days, and a large minority never reply. In more than a decade, the speed gap has not closed. For a local business, that persistence is an opportunity: the bar your competitors have set is remarkably low.

Finding 2: The window that decides the sale is five minutes

If 42 hours is the reality, what’s the target? The most-cited answer comes from a study led by MIT’s Prof. James Oldroyd, which analyzed inbound-lead response data at scale. Its findings are stark: responding within five minutes rather than thirty produced roughly a 100-fold increase in the odds of making contact and a 21-fold increase in the odds of qualifying the lead. The decay is brutally fast even inside those first minutes — the odds of qualifying drop about fourfold between five and ten minutes.

A separate large vendor analysis (Velocify, across roughly 3.5 million leads) points the same direction, reporting that calling within the first minute lifted conversion by 391%. We treat that as corroboration rather than proof — it’s vendor data, and its original report is no longer published — but every credible dataset we found agrees on the direction: minutes, not hours.

Finding 3: Businesses respond ~500× slower than the moment that matters

Put the two anchors together and you get the gap at the heart of this benchmark. The window when a lead is most reachable is about 5 minutes (MIT). The average business takes 42 hours to respond (Harvard) — that’s 2,520 minutes. In other words, the typical response arrives roughly 500 times later than the moment the research says decides the outcome. This isn’t a marketing problem or a pricing problem. It’s a timing problem — and timing is the one variable a system can fix completely.

Finding 4: The silent 23% — what unanswered leads cost, by industry

Here is a number no one seems to have published, and it comes from multiplying two solid figures. Take the average cost per lead by industry (FirstPageSage’s 2025 analysis) and apply Harvard’s finding that 23% of leads are never answered. The result is the lead-acquisition spend that never even earns a reply — money already spent to create demand that simply evaporates.

Cost-per-lead figures: FirstPageSage, blended paid + organic, 2025. Unanswered rate: Harvard Business Review (23%). This is our own calculation, shown so you can reproduce it — and it is deliberately conservative: it counts only the leads that get no reply, ignoring the far larger group answered too late to matter. And that’s before you value the lost job: in dentistry alone, a single new patient is worth about $4,220 a year in production (Sikka Software, across 12,500 practices).

Finding 5: The channel paradox

There’s a mismatch in how businesses respond, too. Gartner Digital Markets reports SMS open rates as high as 98% (with ~45% response), against roughly 20% open and 6% response for email. Yet most local businesses still funnel every inbound lead into a phone call or an email that’s unlikely to be opened. The fastest, most-read channel available — a simple text back — is the one most businesses use last, if at all.

Methodology — and what we refused to use

This benchmark is a synthesis of published research, not a new survey. We prioritized the most prestigious, verifiable sources and combined them transparently. Every headline figure is quoted from its original source; the two derived figures (the ~500× gap and the by-industry cost table) are simple arithmetic on those sources, and we show the math.

Three honest limitations, stated up front:

• The response-time research is B2B and about a decade old. Harvard’s and MIT’s data come largely from B2B web-form leads. Applied to a local plumber’s phone leads, they show direction, not transferable magnitude — so we lead with the pattern, not false precision.
• Cost-per-lead varies widely. The FirstPageSage figures are blended averages and the underlying sample size isn’t disclosed; treat the cost table as an order-of-magnitude estimate, not a quote.
• The “5-minute window” source has aged. The MIT study’s multiples are widely cited and corroborated, but its original host page has since been rewritten; we attribute the finding, not the current webpage.
