Can I search for posts on a topic instead of using one post URL?

Yes, and that is the real power. Periodix Search finds every relevant post on your topic, and the workflow pulls the engagers from all of them, so you cover the whole conversation in your niche, not just one post you already know about. You can also start from specific post URLs when you already have them.

How do I find who liked a LinkedIn post?

Use Get Post Reactions with the post. It returns everyone who reacted, with their profile details, so you never scroll reactions by hand.

Are commenters better leads than likers?

Usually yes. A comment takes more effort than a like, so commenters show stronger intent, and the comment text gives you material to personalize with. This playbook pulls both.

Will this get my account restricted?

Periodix handles LinkedIn rate limiting, and the workflow runs on a schedule rather than in bursts. You control volume, so keep daily actions within safe limits.

Do I need Sales Navigator?

No. This works from LinkedIn posts. Sales Navigator is optional and used elsewhere for people and company search.

What do Get Post Reactions and Get Post Comments return?

Everyone who reacted or commented, with full author details (name, headline, company, profile URL), and for comments the full comment text. That is exactly the structured data the AI uses to score each lead and personalize the opener.

Can I use OpenAI or Gemini instead of Claude?

Yes. The AI steps are standard model calls, so you can point them at Claude, OpenAI GPT, or Google Gemini. The published template uses Claude, but swapping the model does not change the rest of the workflow.

How to Find LinkedIn Post Likers and Commenters and Turn Them Into Leads

// WHEN TO USE

Problem

The people who like and comment on posts in your niche are already raising their hand, and that intent is spread across dozens of posts and buried in the feed.

To work it by hand you first have to find the right posts, then open each one, scroll every reaction, read every comment, and copy profiles.

It does not scale, so the warmest signals go to waste and teams keep buying cold lists instead.

// WHAT YOU GET

Outcome

A scheduled pipeline that finds the posts your buyers engage with on your topic, or starts from posts you already have, pulls everyone who reacted or commented, and runs them cheap-to-expensive: free rules drop obvious non-fits, AI scores only the survivors against your ICP, and only the strong fits get a drafted connection note and first message that reference the exact post or comment they engaged with.

You cover the whole conversation in your niche, not just one post, and you never waste AI or sends on non-fits.

Hot and cold leads land in Google Sheets, ready to send.

No manual scrolling, no scrapers to maintain.
