What is lead scoring and how does it work?

Lead scoring assigns each lead a number that reflects how likely it is to become a customer, so a team with limited hours calls the right people first. A good model uses two independent inputs: how well the lead fits your ideal customer, and how much buying behaviour they have shown.

All answers

How lead scoring works

Score fit and behaviour separately, then read them as a grid rather than a single total. A perfect-fit lead who has done nothing needs outbound; a highly engaged poor-fit lead needs disqualifying, not a call.

InputExample signalsWeight guidance
FitIndustry, employee count, revenue band, region, job titleFixed attributes; set once from closed-won analysis
BehaviourPricing page views, demo request, email replies, repeat visitsDecays over time; recent activity should outweigh old
NegativeFree-mail domain, competitor, student, unsupported regionSubtract aggressively to keep the top of the list clean

How to build your first scoring model

You do not need machine learning to start. Build the first version from your own closed-won data.

  • Export the last 100 to 200 closed-won and closed-lost deals.
  • Find the attributes that appear far more often in won deals than lost ones.
  • Assign points to those attributes; total them to roughly 100 for a perfect lead.
  • Set the qualification threshold where roughly the top 20 to 30 percent of leads land.
  • Review the threshold monthly against actual conversion and adjust.

When AI lead scoring helps

Rule-based scoring reflects what you already believe. A model trained on your historical outcomes finds patterns you did not encode — combinations of source, timing and engagement that correlate with closing. AI scoring is worth adding once you have a few hundred closed deals; below that, a hand-built model is more reliable and far easier to explain to the team.

Alegria RevOps scores leads from synced CRM data and shows the reasoning behind each score, so reps can see why a lead is ranked highly rather than being asked to trust a number.

Prioritisation and follow-up speed

Scoring is worthless if the top-scored lead waits three hours for contact. Pair scoring with routing rules that assign an owner instantly and escalate anything above the threshold that has not been touched within your response target.

Frequently asked questions

What is lead scoring?
Lead scoring is a system that assigns each lead a numeric value based on how closely it matches your ideal customer profile and how much buying behaviour it has shown, so sales teams contact the highest-probability leads first.
How does lead scoring work?
You assign points to fit attributes such as industry and company size, and to behaviour such as pricing page visits or a demo request, subtract points for disqualifying signals, and route leads above a threshold to sales immediately.
How do I know which leads to prioritise?
Rank by fit and behaviour together. Contact high-fit, high-engagement leads within minutes, nurture high-fit low-engagement leads with outbound, and disqualify low-fit leads regardless of how engaged they look.
Can AI predict which leads will convert?
AI models trained on your closed-won and closed-lost history can predict conversion probability more accurately than hand-set rules once you have a few hundred completed deals, because they detect combinations of signals people do not think to encode.
