When converted leads with high scores show little interest in purchasing, it indicates that the lead scoring model may not be accurately reflecting true purchase intent. Evaluating each record against the target marketing persona involves comparing the characteristics of the lead to an ideal customer profile, which helps in ensuring that the scoring is more aligned with actual buying intent. By refining the lead qualification process to better match the target persona, sales teams can prioritize leads that are more likely to convert into customers.
