Can I use Signals to scrape likes and comments from a LinkedIn post?

Last updated: September 25, 2026

Context

You may want to build a prospecting list by targeting people who have liked or commented on a specific LinkedIn post. This is a common intent-based outbound strategy, where engagement on a post signals interest in a topic relevant to your ICP.

Answer

Yes. This is exactly what LinkedIn engagement Signals are for. Topo has one for every kind of post you'd want to watch: your company page, your own profile, your colleagues' posts, a competitor's page or its employees, a partner's or a customer's page or their employees, any company page, or any influencer's profile. Each is listed in 📄 Signals 101.

Go to the Signals page, pick the signal you need, set its criteria and your daily cap, and launch it. Topo then watches those posts continuously and feeds the people who engage into a live list for as long as the signal is running.

You no longer need an external scraping tool or a CSV import for this.
