Can I use Signals to scrape likes and comments from a LinkedIn post?
Last updated: September 8, 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 three of them:
Company post engagement — people who react to or comment on your own company's LinkedIn posts.
Competitor post engagement — people who react to or comment on a competitor's LinkedIn posts.
Person post engagement — people who react to or comment on a specific person's LinkedIn posts.
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.
