Honestly, the most overlooked signal for me is when someone checks out my LinkedIn profile right after I've engaged with their content. It's that quiet curiosity-they're sizing you up before they're ready to say a word.
we started noticing this pattern a while back, and it turned out that leads who did that reverse-lookup within a couple of days of our first touchpoint were roughly four times more likely to eventually book a call. It's not a silver bullet, but it's a powerful nudge that they're paying attention.
A few other clues that have worked for us: coming back to the pricing page more than once, watching over half of a video (if you're using video in outreach), and-this is oddly specific-clicking through to case studies from industries that look like theirs. The detail tells you they're not just browsing, they're imagining themselves in that outcome.
The hard part is connecting those breadcrumbs without drowning in data. For our top 30 target accounts, we just keep a manual spreadsheet. No fancy automation-just honest observation.
What signals do you actually have visibility into with your current setup?
