Lead Scoring

Most sales teams treat all inbound leads equally — first in, first called. Lead scoring breaks that pattern by giving every lead a number, so reps spend their first hours of the day on the 20% of leads most likely to close, not the 80% who downloaded a white paper and went cold.

What is lead scoring?

Lead scoring is a shared framework between marketing and sales that assigns point values to attributes and behaviours, producing a single score that summarises each lead's buying potential.

Two dimensions drive most scoring models:

• Fit score (demographic / firmographic) — does this lead look like a customer? Criteria include job title, seniority, company size, industry, and geography. A VP of Marketing at a 300-person SaaS company scores high; a student at a 2-person startup scores low.
• Engagement score (behavioural) — is this lead showing purchase intent? Criteria include pricing page visits, demo requests, webinar attendance, email open rates, and content downloads. High-intent signals (pricing page, demo) score higher than low-intent signals (blog visit, ebook download).

The combined score is used to decide:

• When a lead becomes an MQL (Marketing Qualified Lead) and routes to sales
• Which sales rep receives it (often combined with lead routing rules)
• What nurture sequence a low-scoring lead enters

Why lead scoring matters for pipeline quality

The problem lead scoring solves is not lead volume — it is lead quality. Three specific pain points it addresses:

1. Sales time on wrong prospects. Without scoring, reps spend equal time on a CFO who visited the pricing page three times and a student who downloaded a guide. Scoring surfaces the CFO immediately.
2. MQL-to-SQL friction. Marketing and sales often disagree on what a "good lead" means. A scoring model with agreed thresholds makes the definition explicit and measurable, reducing the "marketing sends us garbage" argument.
3. Lead waste. Leads that are not ready to buy are not bad leads — they are early leads. Scoring routes them to nurture sequences instead of sales queues, preserving them for when timing improves.

How lead scoring works

Building a scoring model is a three-step process: define criteria, assign weights, and set thresholds.

Step 1: Define fit criteria

Pull your last 50 closed-won deals. What attributes do they share? Common fit criteria and example scores:

Step 2: Score engagement

Track behavioural signals and assign points based on purchase-intent weight:

• Demo request: +25 points
• Pricing page visit: +20 points
• Webinar attendance: +15 points
• Email opened (per open): +5 points
• Blog post visit: +2 points
• No activity in 30 days: -10 points

Step 3: Set thresholds

Agree on MQL and SQL thresholds with sales before launching. Typical ranges:

• 0-39: Not ready — enters nurture sequence
• 40-69: MQL — marketing continues nurturing with higher-touch content
• 70+: SQL — routes to sales with a 15-minute response SLA

Real lead scoring examples

Example 1: B2B SaaS close rate improvement

A project management SaaS implemented scoring with five criteria: +10 for matching industry, +15 for VP or above title, +20 for pricing page visit, +5 per email opened, +25 for demo request. Leads reaching 60+ transferred to sales. Close rate improved from 12% to 22% in 90 days. The gain came from removing unqualified leads from sales queues, not from better sales technique.

Example 2: Negative scoring in practice

A B2B agency added negative scores to reduce noise: -20 for student email domains, -10 for companies under five employees, -15 for no website visits in 30 days. This alone removed 34% of "leads" from the sales queue — leads that had never purchased in three years of data review — without changing any outbound sequences.

Lead scoring vs predictive lead scoring — key differences

7 lead scoring best practices

1. Align on thresholds with sales before launch. If marketing defines MQL at 40 and sales expects SQL-quality leads, the model creates conflict rather than alignment. Agree on what each tier means and what sales does at each threshold.
2. Start with 5-8 criteria, not 30. Complex models are hard to debug and maintain. Start lean, run for 90 days, then add criteria where gaps appear in the data.
3. Weight intent signals above fit signals. A perfect-fit lead who never engages is less valuable than an 80%-fit lead who requests a demo. Engagement predicts purchase timing; fit predicts deal potential.
4. Include negative scoring. Attributes that disqualify leads — wrong company size, competitor domain, no activity — should actively reduce the score, not just fail to add points.
5. Decay inactive scores. A lead who scored 75 six months ago and has not visited since is not a 75 today. Apply a time decay: -5 points per week of inactivity Based on product docs, public reviews, and hands-on product exploration.
6. Calibrate quarterly against closed deals. Compare the scoring attributes of closed-won deals versus closed-lost. Adjust weights to better reflect what actually predicts a close in your specific market.
7. Create a feedback loop with sales. Ask reps to flag leads that are clearly mislabelled — high scorers who were terrible fits, low scorers who closed quickly. This qualitative signal is more accurate than retrospective data alone.

Common lead scoring mistakes to avoid

• Scoring without alignment. Marketing builds the model alone, sets the thresholds, and sales ignores it. Shared ownership of criteria and thresholds is the only way the model gets used.
• Too many low-weight criteria. Thirty criteria each worth 1-2 points create noise. Five high-weight criteria create signal. Fewer, more decisive attributes produce more actionable scores.
• Scoring page visits without context. A career page visit is not a purchase signal. A pricing page visit is. Track what pages a lead visits, not just that they visited the site.
• No MQL follow-up SLA. A lead that reaches MQL threshold and sits in a queue for 48 hours might as well not have been scored. The score is only valuable if it triggers a response time commitment.
• Never revisiting the model. A model calibrated on 2024 data may not reflect 2026 buying behaviour. Quarterly review is the minimum; semi-annual full rebuild is ideal for high-growth teams.
