# Account Scoring: Definition and Guide for B2B Marketers
Account scoring is a systematic method for ranking target accounts based on their likelihood to become customers. It combines fit scores (firmographic and technographic alignment with your ICP) and engagement scores (behavioral signals indicating active buying intent) to prioritize which accounts sales and marketing should pursue.
Account scoring models start with your best customers: what do they look like before they buy? Extract firmographic patterns, then add behavioral weighting. A marketing automation or ABM platform continuously scores all accounts in your target list by comparing them against your model. When a fit-score account shows engagement (visits your pricing page, downloads a competitor comparison), their engagement score spikes, triggering a sales alert. Sales contacts the account while intent is hot. As weeks pass without engagement, the score naturally decays, shifting focus to fresher prospects.
Account scoring is ABM's operating system: it automates prioritization across thousands of target accounts so sales and marketing focus on the highest-probability opportunities. Without scoring, teams waste time on low-fit accounts that reached out or low-engagement accounts that technically fit your ICP. Scoring also prevents pipeline bloat: by focusing on high-scoring accounts, you improve win rates and shorten sales cycles. Additionally, account scoring uncovers expansion opportunities: existing customers with high engagement in adjacent use cases signal potential upsell targets.
