LinkedIn activity can help you build timely lists from profile visits, followers, events, posts, engagement, or prepared LinkedIn URLs. Use the source that matches the specific signal, then qualify the people before you treat them as outreach candidates.
A like, comment, follow, or event registration is context—not proof of buying intent. Protect the connected account, keep the first run small, and confirm company and persona fit before any message is prepared.
| Starting signal | Suitable source where available | Check first |
|---|---|---|
| People who interacted with a post | The LinkedIn post or engagement source that matches the specific post URL. | The URL is supported, the post is accessible, and the engagement is relevant to your audience. |
| Visitors or activity connected to a profile | The relevant profile-activity or profile-visitor source. | The correct LinkedIn account is connected and permitted for the workflow. |
| New followers or company-page activity | The matching company-page follower or activity source. | You have access to the page or public activity required by the current flow. |
| People associated with a LinkedIn event | The specific event-attendee source. | Use the exact event URL and confirm that the event data is available. |
| People discussing a defined topic | The relevant topic or post-discovery source. | The topic is precise enough to avoid unrelated results. |
| A prepared set of LinkedIn URLs | The upload or LinkedIn-URL source shown in your workspace. | The URLs are current, necessary, and appropriate to process. |
Source names and availability can vary. Sales Navigator or other account-dependent imports may be unavailable or disabled in some workspaces, so rely on the current UI and do not promise an unsupported flow.

Do not send every engagement result directly to outreach. First ask whether the company fits your target market, whether the person has a relevant role, and whether the activity creates a reasonable reason to engage.



| Problem | Solution |
|---|---|
| The source returns no new leads | Check the connected account, permissions, URL type, time window, refresh behaviour, and whether the people already exist in the list, another list, or a blacklist. |
| The source returns too many irrelevant people | Narrow the source, reduce the limit, strengthen company and persona scoring, add exclusions, and review a new sample. |
| A LinkedIn URL is rejected | Confirm that you copied the complete supported profile, post, event, or company-page URL without tracking parameters. If the current UI still rejects it, do not substitute another URL type. |
| The expected source is missing or disabled | Availability can depend on the workspace, plan, account, and permissions. Ask a workspace administrator rather than assuming the source is enabled. |
| A result is relevant to the post but not to your offer | Treat engagement as context, not buying intent. Apply company fit, persona fit, exclusions, and a manual review before outreach. |
Choose your list source by starting with what you already have and what you want the list to do next. If you begin with the source name alone, it is easy to pick something too broad, too narrow, or not available in your workspace.
Use AI Company Search to describe target companies in natural language, and use news or signal monitoring to watch for specific events. Both work best when your prompt is verifiable, your exclusions are explicit, and each result has a defined review or follow up action.
Use an XLSX upload when you already have a defined set of people, companies, or job titles. A clean file and a careful preview help Signalist match the right records and reduce avoidable duplicates, credit use, and manual correction.
