Signals are event-driven sources for FirstTouch flows. Instead of starting from a saved contact list, a signal-based flow starts from tracked activity such as website visits or LinkedIn engagement. Signals are a source type in FirstTouch, alongside audiences. A signal flow enrolls contacts when matching signal events are available. ## Signal Types Install the FirstTouch tracking pixel, publish it on your website, and verify that visitor tracking is live. Monitor LinkedIn person profiles and company pages, then use captured likes and comments as outreach signals. ## What You See On The Signals Page Open Signals in FirstTouch at [`https://app.firsttouch.ai/signals`](https://app.firsttouch.ai/signals). The Signals page shows a table with: * `Name` * `Enabled` * `Flow` If a flow is linked, the Flow column opens that flow in Flow Builder. ## Configure A Signal Select a signal row to open its right-side drawer. The drawer changes based on the signal type. For **Website Visitors**, use the drawer to: * copy your team's tracking script * install the script in your website's `` * run **Check now** after the site is published See [Website Visitors](/WebApp/Signals/Website-Visitors) for platform-specific setup steps. For **Social Engagement**, use the drawer to: * add LinkedIn person profile or company page URLs * review monitored URL connection status * open captured likes, comments, and unique engagers See [Social Engagement](/WebApp/Signals/Social-Engagement) for allowance, setup, and outreach examples. ## Enable Or Disable Signals When a signal is unlocked, you can turn it on or off from the `Enabled` column. * Turning a signal on allows new matching events to be used by its linked flow. * Turning a signal off stops new signal-driven intake for that signal. The setting persists after refresh. Enabling a signal does not guarantee outreach. The linked flow still needs to be valid, published, and able to process new enrollments. ## Locked Signals Some teams may see locked signals instead of toggles. When a signal is locked: * the `Enabled` column shows a lock icon * the `Flow` column may show `-` * the page includes a `Contact us` link to request access Lock state is account-dependent. Some workspaces may see a mix of unlocked and locked signals, while others may see all signals locked. ## Signals And Flows Signals are tied to flows rather than standalone outreach. * use the `Flow` column to open the linked flow * in Flow Builder, signal-based sources are treated as `Contact-level signal` * signal flows are distinct from audience-based flows ## Related Behavior In Flow Builder For signal-sourced flows: * the flow source is signal-based, not audience-based * Flow Builder can show awaiting signal events before enrollment * signal event enrollment is handled from the flow, not from the Signals table * some signal flows may require you to review and enroll awaiting signal events manually ## Notes * Signals and Audiences are two different source types in FirstTouch. * Audiences start from a saved group of contacts. * Signals start from matching events tied to a signal source.
