Substack Post Search

Substack search surfaces articles from across its platform of independent newsletters - technology, business, culture, politics, health, and every niche in between. Unlike topic leaderboards that show trending content, search results respond to specific queries, revealing the depth and breadth of coverage that exists for any term or phrase on the platform. For researchers mapping how a topic is covered across Substack's newsletter ecosystem, marketers identifying writers who discuss relevant subjects, and content strategists studying competitive coverage, search-based extraction provides a different and complementary view to leaderboard data.

What it extracts

• Position — Numerical ranking of the post in search results.
• Title — Headline of the Substack article.
• Description — Opening text preview from the article.
• Writer — Author who published the post.
• Time of Read — When the article was published.
• Company's Name — The Substack publication it belongs to.
• Link — Direct URL to the full article.
• Image URL — Thumbnail or featured image associated with the post.

What you can do with it

• Topic coverage mapping: Search for a specific term and see every Substack post that discusses it. Understand the full range of perspectives and angles available on the platform.
• Writer discovery beyond leaderboards: Leaderboards show top performers, but search reveals niche writers who cover your topic deeply. These are often the most knowledgeable voices.
• Brand mention monitoring: Search for your company or product name to find every Substack post that mentions you. Understand how newsletter writers perceive and discuss your brand.
• Keyword-level content intelligence: Track which specific terms and phrases Substack writers associate with your industry. This informs your own content and SEO keyword strategy.
