How to Use Substack Tags and Sections So Google Actually Understands Your Newsletter
If your Substack archive feels like a junk drawer, you are not alone. Posts live everywhere, tags are random, and Google has no clear story about what you write.
The good news: with smart use of substack tags sections, you can turn that chaos into a clear map that both readers and search engines understand.
In this guide, you will learn what tags and sections really do, how to set them up for different newsletter types, and how to run a quick audit to clean up what you already have.
What Google Sees When It Looks At Your Substack
Think of Google as a very fast, very picky reader. It scans your:
- Publication home page
- Individual posts
- Sections
- Tag pages
From that, it tries to answer one simple question: “What is this site about?”
Substack already handles a lot of the technical work for you. Their own SEO guide for Substack explains how titles, URLs, and sitemaps feed into Google. Your job is to give Google a clear content structure on top of that.
That structure comes from:
- Sections, which act like main shelves in a library
- Tags, which act like labels on each book
When those shelves and labels are clear and consistent, Google can group your posts, understand your themes, and send the right searchers to your archive.
Tags vs Sections: Simple Definitions For Busy Creators
You do not need to be “into SEO” to get this part right. Just remember this:
Sections: Big buckets of content
Sections are broad. They show up on your publication and help readers and Google see your main types of content.
Good section examples:
- Essays
- Weekly Briefing
- Deep Dives
- Podcast
You will set these in your Substack dashboard under Sections. Most newsletters only need three to six sections.
Tags: Specific topics inside those buckets
Tags are more detailed. You add them inside the post editor.
Good tag examples:
- ai tools
- morning routine
- ethereum
- creator burnout
Tags explain what this post is about, inside the larger section. They are not hashtags for growth. They are signposts for humans and search engines.
Good vs Bad Tag Structures (With Real Naming Ideas)
Random tags confuse everyone. Google, readers, and you.
Here is a quick look at messy vs clean tag habits:
| Newsletter type | Messy tags (bad) | Clean tags (better) |
|---|---|---|
| Tech analysis | tech, random-thoughts, longform, update | ai, product-management, saas-pricing |
| Personal essays | life, thoughts, rambling, journal | relationships, creativity, grief, parenting |
| Crypto newsletter | crypto, btc, chain-stuff, moonshots | bitcoin, ethereum, defi, onchain-governance |
| Productivity | productivity, habits-again, routines-2 | time-blocking, deep-work, habit-tracking |
A few simple rules:
- Use 3 to 5 tags per post
- Make tags short, clear phrases
- Repeat the same spelling every time (pick “ai” or “artificial-intelligence”, not both)
If you want more depth on how tags work inside Substack itself, Linda Caroll breaks this down in The Best Way To Use Substack Tags.
Sample tag sets by niche
Here are concrete sets you can reuse or tweak.
Tech analysis
- Sections: Essays, Weekly Briefing, Founder Playbooks
- Core tags: ai, saas, product-management, fundraising, growth-strategy
Personal essays
- Sections: Essays, Letters, Resources
- Core tags: creativity, aging, motherhood, mental-health, career-change
Crypto newsletter
- Sections: Market Notes, Deep Dives, Beginner Guides
- Core tags: bitcoin, ethereum, defi, layer-2, regulation, onchain-data
Productivity newsletter
- Sections: Weekly Playbook, Case Studies, Tools
- Core tags: habit-tracking, focus, time-blocking, burnout, workflows
Notice how each set stays tight. No “misc”, no “random”, no “thoughts”.
How To Set Up Sections So Google Gets Your Topics
Sections are where many writers either overdo it or ignore it.
Here is a simple way to set them up.
- List your content types for the last 2 months
Do you mostly write essays, link roundups, Q&A, or tutorials? - Group them into 3 to 6 sections
Some ideas:- Format based: Essays, Interviews, Roundups, Podcast
- Audience based: Beginner Guides, Advanced Playbooks, Behind The Scenes
- Make section names boring on purpose
“Essays” is better than “Midnight Mind Dumps”. Google and new readers do not know your inside jokes yet. - Avoid duplicate ideas between sections
Do not use “Crypto Notes” and “Bitcoin Notes” as two sections. Make “Market Notes” the section, then use tags like bitcoin, ethereum, defi.

Quick Audit Framework To Fix Your Existing Tags And Sections
Maybe you already have two years of posts and a wild tag list. You do not need to fix everything in one sitting.
Use this mini audit on a quiet afternoon.
- Export your current brain
Open your archive, skim 30 to 50 posts, and write down every tag and loose “theme” you see. - Pick your “master” list
From that messy list, choose 10 to 20 tags you want to keep going forward. These become your default menu. - Merge near-duplicates
Decide that “ai” replaces “artificial-intelligence”, “genai”, and “ai-tools”. Decide that “morning-routine” replaces “am-routine” and “mornings”. - Update your most important posts first
Start with your top 20 posts, or the ones people keep finding from search. Clean their sections and tags so they match your new system. - Use a simple checklist for new posts
Before you hit publish, ask:- Is this in the right section?
- Are there 3 to 5 focused tags from my master list?
For a broader post-level checklist, Kristi Koeter’s Substack post optimization checklist pairs well with this audit.
What Tags And Sections Can’t Do (Limitations To Know)
Tags and sections are not magic growth buttons.
Substack does not give you bulk tag editing yet, so cleanup takes some manual work. Tag pages are also pretty simple, you cannot control them like a full custom blog.
And as Karen Cherry points out in How to Use Tags to “Grow” Your Substack, tags alone will not give you 45,000 subscribers. They help Google and humans understand you, they do not replace strong content or a real audience strategy.
Use substack tags sections as clarity tools first, growth tools second.
Bring It All Together For A Clearer Newsletter
When your sections act like clear shelves, and your tags act like honest labels, Google’s job gets easier. Your archive looks cleaner, your readers find what they need faster, and old posts have a better shot at steady search traffic.
Start small. Pick your main sections, tidy your tag list, then fix your top posts. After that, every new post you publish will drop neatly into place.
If you already use tools like Dispatchrly to schedule your Substack Notes and stay consistent, this structure work will help every new piece you share point back to a clear, well-organized home.
Your newsletter is already doing the hard part, the writing. Now let your tags and sections tell Google exactly what that writing is about.
