There is no universally good lead number, because raw lead volume is the wrong target for relationship-driven B2B companies. A booth that collects 400 badge scans often produces fewer real opportunities than a booth that has 25 substantive conversations with target accounts. Instead of chasing a lead count, set a goal for qualified conversations with named priority accounts and follow-up meetings booked on-site. Five documented conversations with decision-makers at priority accounts are worth more than fifty anonymous business cards.
