Overview

Substack Archive Posts
Substack has become the dominant platform for independent newsletter publishing, hosting thousands of writers who generate revenue directly from paid subscriptions. Each Substack publication has a public archive page listing every post - both free and paid - in reverse chronological order. Archive entries show the post position, title, publication date, description snippet, comment count, like count (hearts), featured image, and whether the post is free or behind the paywall.
What it extracts
- Position — The sequential order of the post in the archive listing.
- Title — Newsletter post headline.
- Description — Opening snippet or preview text of the post.
- Date — When the post was published.
- Number Of Likes — Hearts/likes from subscribers.
- Number of comments — Reader comments on the post.
- Link — Direct URL to the full post.
- Image URL — Thumbnail or featured image associated with the post.
What you can do with it
- Newsletter content catalog: Extract every post a Substack publication has ever made. Understand their content volume, publishing cadence, and how their approach has evolved.
- Free vs. paid content strategy: Substack archives distinguish free posts from paid-only content. Extract these labels to study how newsletters balance free content for growth with paid content for revenue.
- Engagement signals: Like counts and comment counts reveal which posts generated the most audience interaction. Extract these to identify topics and formats that drive subscriber engagement.
- Publishing frequency patterns: Extract dates across the full archive. Analyze whether a newsletter posts daily, weekly, or irregularly - and how frequency correlates with engagement.
