TL;DR: The Activity panel is this lead's signal history, newest first. It's a read-only timeline — use it to see what the lead actually did and decide which messaging hook to lead with.
What you see per entry
Each row in the Activity panel:
- Dot — green for a positive signal (the kind that suggests real buying interest), yellow for everything else. It is not a per-signal-type colour code
- Signal name — "Keywords", "Job Changes", "Demo Viewed", etc.
- Recency — "1w ago", "2w ago" (relative timestamp, hover for exact)
- Source attribution — under the signal name, a one-line context (e.g. "Posted about SOC2 on LinkedIn", "Replied to Q4 Outbound sequence", "Watched product demo on Vidyard")
The list is sorted by recency, newest first. Below the rows: See all (N) link expands to full history.
The rows are not links
Worth knowing before you go hunting for a click target. A row doesn't open a filtered signal-detail view, and there's no way from here to see the rule that fired or the other leads it captured.
The one thing that is clickable is the row's detail when it happens to be a URL — the LinkedIn post, say. That opens the source itself in a new tab, which is usually the proof you actually wanted.
To see everything a rule captured, go the other way round: open the signal, find the rule, and click its funnel number. That drills into Leads filtered to exactly those records.
What it tells you about messaging
The signal history is the strongest source for outbound messaging. A canonical pattern:
- Latest signal — your opening hook ("Saw your post about X yesterday")
- Second-latest signal — reinforcement, especially if it's a different category ("And noticed you started at Y two months ago")
- Pattern across signals — frame for the meeting ("Curious how you're thinking about Z given both")
Copilot's > draft an email referencing this lead's recent signals reads the Activity panel and structures the message around the highest-conversion signal in the history.
No filtering, and no detaching
The expanded view (See all) is a plain chronological list. There is no filter by signal type or date, and no search across the entries — on a lead with a long history you scroll.
There's also no way to detach a signal from a lead. If a signal was attributed to the wrong person because an enrichment match was wrong, the attribution stays; nothing in the product removes it.
