How can I explain those signals clearly to a client?

Use a simple briefing: baseline, changes, and meaning. Treat discovery, retrievals, and confirmed referrals as observable activity, not promised outcomes. Here's a ready-to-use template you can drop in: Baseline period: [date range]. Signals tracked: discovery, retrievals (with approved facts), and referrals. Changes since baseline: [status]. What it means: better coverage, clearer Q&A, and richer visual context. Important note: these signals show visibility and knowledge readiness, not sales results. For delivery, keep the same signals in the same terms each update and add a plain-language note about what you learned for the client. That helps them understand impact without implying guaranteed outcomes.
