What the ratio measures.
A sales-accepted lead (SAL) is a lead that marketing has passed to sales and that sales has agreed to work. The ratio tells you how many of the leads marketing produces are good enough for a salesperson to act on.
It sits between two other measures. A marketing-qualified lead (MQL) meets marketing's own criteria, such as a score or a content download. A sales-qualified lead (SQL) is one sales has gone on to qualify as a real opportunity. The SAL is the point where sales agrees the lead is worth a conversation, which is why it is the first place a weak programme shows up.
How to calculate it.
Lead-to-SAL ratio = sales-accepted leads ÷ marketing leads, for the same period and the same source.
Example: if marketing produces 1,000 leads in a quarter and sales accepts 20, the ratio is 2%. Work it out by source as well as overall, because search, LinkedIn and email will not behave the same way.
Two rules keep the number honest. Agree the definition of a lead, and of acceptance, with the head of sales before you start. And measure leads by the date they were created, so late acceptances do not flatter the next period.
Why we report this and not form fills.
Traffic, clicks and form fills are easy to grow and easy to report. They do not tell you whether sales found any of it useful. A programme can double its leads while the share sales accepts stays flat, or falls.
Reporting the lead-to-SAL ratio puts marketing and sales on one number. It also shows where leads stall: at the source, at the handover, or in follow-up.
Five things that change the ratio.
A shared definition
Sales and marketing agree what an acceptable lead looks like before campaigns launch, and write it down.
The source mix
Different channels produce different quality. In the case below, SEO leads were accepted at 4.37% and search campaigns at 2.12%.
Content and intent
Resources that match a buyer's stage attract the right people. Generic downloads attract the wrong ones.
Scoring and nurture
Scoring and behaviour-triggered email workflows show sales which leads are warm, and keep the rest warm until they are.
Handover and speed
Clear rules and alerts decide who follows up, and how quickly. Slow follow-up lowers acceptance.
One IT services company: 0.22% to 4.12% in twelve months.
A top-5 Indian IT company had traffic and a strong sales team, but marketing leads reached sales-accepted status at 0.22%. Over twelve months we rebuilt the site structure for search, added a blog and a gated resource section, ran search and LinkedIn campaigns into it, and nurtured every contact in Pardot. The overall ratio reached 4.12%, with organic traffic up 712% and about 4,200 qualified B2B contacts added.
A 90-day plan to improve it.
Days 1 to 30: Baseline
Agree lead and acceptance definitions with sales. Measure the current ratio by source, and find where leads stall.
Days 31 to 60: Fix the leaks
Change the scoring, the handover rules and the follow-up speed. Pause the sources that never get accepted.
Days 61 to 90: Shift the mix
Move budget and effort to the sources and content that produce accepted leads, and report the ratio monthly.
Agree the definitions before you measure anything.
Most disputes between marketing and sales are really arguments about definitions. Write each stage down, name who decides it, and give it a rule that two people would apply the same way.
| Stage | Who decides | Example rule |
|---|---|---|
| Lead | Marketing | A named person at a company in your target market who has asked for something: a form, a demo, a download. |
| MQL | Marketing | A lead that meets fit (role, company size, industry) and engagement (score above an agreed threshold). |
| SAL | Sales | A lead a salesperson has reviewed and agreed to work, within an agreed time. |
| SQL | Sales | A SAL that, after a conversation, has a real need, budget, authority and timing. |
| Opportunity | Sales | An SQL with a deal created in the CRM. |
Two additions make the SAL stage reliable. First, a time limit: a lead the sales team has not accepted or rejected within, say, two working days returns to marketing automatically. Second, reason codes: every rejection carries one, such as not a fit, duplicate, student or job seeker, competitor, wrong region, existing customer, or no response. Reason codes turn a rejected lead into information about what to fix.
Why the biggest source is often not the best one.
The numbers below are illustrative, to show how the ratio changes decisions. Marketing generated 1,200 leads in a quarter from four sources.
| Source | Leads | Sales-accepted | Lead-to-SAL | Reading |
|---|---|---|---|---|
| Organic search | 300 | 12 | 4.0% | Best quality. Invest here first. |
| Search ads | 250 | 7 | 2.8% | Fine. Tighten keywords and the form. |
| LinkedIn ads | 350 | 6 | 1.7% | Review audience and offer. |
| Gated content and events | 300 | 2 | 0.7% | Mostly low-fit contacts. Fix the offer. |
Overall, 27 of 1,200 leads were accepted, a ratio of 2.25%. Reading only the lead count, gated content looks as productive as organic search, at 300 leads each. Reading the ratio, organic search produces six times as many accepted leads from the same volume. Add the cost of each source and you can work out the cost per SAL, which is the figure to compare when you move budget.
The same pattern showed up in our top-5 IT company case, where SEO leads were accepted at 4.37% and search campaigns at 2.12%. Source mix is usually the fastest lever, because it needs no new campaign, only a decision about where to put effort.
Where leads stall, and what to do about it.
| Symptom | Likely cause | What to try |
|---|---|---|
| Plenty of leads, few accepted | Offer or targeting attracts the wrong people | Tighten targeting and the offer. Add fit questions to the form. Pause sources with the lowest ratio. |
| Sales rejects leads as not a fit | No shared definition of fit | Rewrite the definition with sales. Score fit separately from engagement. |
| Leads accepted late, or never | Slow or unclear handover | Set a time limit and alerts. Route by region or service. Report time to accept. |
| Good leads go cold | No nurture between interest and readiness | Build role-based nurture tracks and re-alert sales when behaviour changes. |
| Ratio falls as volume rises | Growth came from weaker sources | Look at the ratio by source before you scale any one of them. |
| Marketing and sales dispute the number | Different systems or definitions | Report from the CRM, with one definition, and review it together monthly. |
Speed and rules decide how many leads sales accepts.
A lead is warmest when it arrives. Agree a service level with sales and measure it: for example, demo and contact requests acknowledged the same working day, other leads reviewed within two working days. Alert the owner by email or chat, not only in a CRM queue nobody opens.
Decide routing in advance by region, service line or company size, so no lead waits for someone to assign it. Give the sales team a one-line summary with each lead: the source, the page or resource that triggered it, and what the person did before and after. A lead with context gets a better first call, and a better call gets a better chance of acceptance.
The one-page monthly report.
- Leads and SALs by source, with the ratio for each, grouped by the month the lead was created.
- Cost per lead and cost per SAL for each paid source.
- Time to accept, and the share of leads accepted or rejected within the agreed time.
- Rejection reasons, ranked, so marketing can see what to fix.
- Pipeline created from SALs, once the sales cycle allows it.
- Three actions for next month, each with an owner.
Use cohorts: group leads by the month they were created and track what happens to each group. Otherwise a strong month of acceptances can hide a weak month of leads. Because B2B IT sales cycles are long, treat the SAL ratio as the leading measure, and tie it to revenue as deals close.
Six mistakes that make the ratio misleading.
Changing the definition mid-way
A tighter or looser rule moves the number without any change in quality. Keep the definition fixed, and note when you change it.
Counting form fills as leads
Test submissions, spam and existing customers inflate the base. Clean the lead count first.
Letting sales reject without a reason
You lose the best data you have about what to fix.
Mixing sources
One blended ratio hides the sources that work and the ones that do not. Always report by source.
Chasing the ratio alone
A very high ratio on very few leads is not a win. Watch volume and cost per SAL beside it.
Reporting from two systems
If marketing reports from one tool and sales from another, the number will never agree. Use the CRM.
