Writing Substack Notes That Get Found in Search

Published: September 2026

The honest answer up front, because it changes everything else in this article: Substack Notes are not indexed by Google, Bing, or any other search engine. If you're trying to write Notes with the same keyword-and-ranking mindset you'd use for a blog post, that effort is misplaced - there's no search engine on the other end of it to reward.

Why Notes and posts are treated completely differently

Substack draws a hard line between the two formats. Your full posts live on real, permanent web pages, get included in your publication's sitemap, and can be submitted to Google Search Console like any other website - which is why a well-optimized post can rank and drive search traffic for months or years. Notes are architecturally different: they're designed and treated as platform-internal, ephemeral content, closer to a tweet or a status update than a web page. Anyone with a direct link can open a specific Note, but there's no crawlable, indexable version of it sitting on the open web the way a post has. If your goal is genuine Google search visibility, that effort belongs entirely on your posts and About page, not your Notes.

Substack's own in-app search isn't reliable either

It's not just external search engines - Substack's own search, inside the platform, is widely reported as weak. One detailed complaint lists four specific, concrete failures: search that "can't find posts even when I know the exact title or URL," no way to search across just two specific newsletters at once, inconsistent results even within a single newsletter you already know contains the post, and messy people-search results that surface spelling variants before the actual name you typed (Karen Smiley). Some writers work around this by building an external Google Programmable Search Engine scoped to Substack results, which is a reasonable fix for finding posts - but it doesn't change the underlying fact that Notes themselves live outside any of this.

So what does "getting found" actually mean for a Note

Since traditional search isn't the mechanism, the entire question of Note discoverability lives inside Substack's own Notes feed and its recommendation logic instead. This isn't a consolation prize - it's actually the dominant growth channel on the platform right now, just a fundamentally different one than SEO. The two levers that determine whether a Note gets found are:

• The Notes feed algorithm, which Substack's own Head of Machine Learning has described as optimized to convert readers into subscribers, not to reward specific keywords or phrases the way a search engine would
• Restacks, which are the closest thing Notes has to a distribution mechanic that crosses audience boundaries - the equivalent of ranking well, but earned through resonance and audience overlap rather than keyword optimization

Trying to "SEO" a Note by stuffing it with keywords not only wastes effort aimed at a search engine that will never see it - it can actively work against you in the feed, since Notes that read as generic or engineered tend to underperform genuinely specific, opinionated ones.

What to actually optimize for a Note, instead of keywords

If you're used to thinking in SEO terms, the closest useful reframe is: optimize for the reader scrolling past you in the feed, not a search query. That means the things that actually move the needle are the same ones covered in the research on what makes a Note perform well - a strong opening line, genuine specificity, and formatting that's easy to scan - rather than anything resembling a meta description or a target keyword.

Where your SEO effort should actually go

None of this means SEO doesn't matter for your Substack presence - it means it belongs somewhere else entirely. Your posts are the indexable, permanent asset; that's where keyword research, title optimization, internal linking, and Google Search Console setup genuinely pay off over time, the same way they would for any blog. Notes are the fast, ephemeral distribution layer sitting on top of that - the relationship between the two formats is covered in more detail elsewhere on this blog - and trying to apply post-level SEO discipline to Notes is solving a problem Notes were never built to have.

The bottom line

There's no version of "Notes SEO" in the traditional sense, because there's no search engine indexing Notes to optimize for. Getting a Note found is entirely a function of the Notes feed algorithm and restack-driven distribution, not keywords - while genuine SEO effort belongs on your posts, which are the actual permanent, indexable asset in your publication. Redirecting your optimization instincts to the right format for each is the real fix here, not trying to force search-engine logic onto content that search engines will never see.
