Internal Linking for a Blog With Under 30 Posts
Every internal linking guide assumes you have 100 posts and a tidy content hub. You have 18. This confusion is everywhere because almost all SEO advice gets written by people working with mature sites, then applied by people who are three months in. The advice isn't wrong. It's just for a different stage. Internal linking strategy for a small blog needs its own rules, because hub and spoke doesn't work until you have enough spokes to actually spoke with.
"You need pillar pages and cluster content"
The kernel of truth here is real: topic clusters work, and Google does reward sites that show depth on a subject. But a pillar page with three thin cluster posts under it isn't a cluster. It's four posts pretending to be a system. I've seen founders spend a month building a "content hub" architecture for a blog that had 9 live articles. That's like designing an org chart for a company of three people. Build the pillar when you have 8 to 10 posts that could genuinely sit under it. Before that, you're not clustering, you're just naming folders.
"More internal links always help SEO"
This is the one that does the most damage. People read that internal links pass authority, so they cram 15 links into a 900-word post, half of them irrelevant. Readers bail. Google can tell when a link exists because it helps the reader versus when it exists because someone read a checklist. On a small blog the real risk isn't under-linking, it's over-linking to posts that don't deserve the click. A blog with 20 posts and 200 internal links scattered across them looks desperate, not authoritative.
"Your homepage and nav menu handle internal linking"
Nav links count, technically. But they're the weakest form of internal linking because they're identical on every page. Google discounts boilerplate links because they carry no context about what the page is actually about. A link inside a sentence, pointing to a relevant post, tells the crawler and the reader something specific. If your "internal linking strategy" is just a menu with 8 categories, you're doing navigation, not linking.
What actually matters instead
With under 30 posts, forget architecture. Focus on three things: linking with intent, linking both directions, and building what I call a spine instead of a hub.
Here's the spine method. Pick your 3 best posts right now, the ones with the most traffic or the ones you're proudest of. These become your spine posts. Every new post you publish links to at least one spine post, and you go back and add a link from one spine post to the new one. That's it. Two links minimum per new post, placed naturally in a sentence, not bolted on at the bottom under "Related Reading."
When I scaled a DTC brand from $100K to $3M, the blog started at 6 posts. I didn't build categories. I picked the two highest-converting posts and made sure every new post referenced one of them within the first 300 words, where readers actually click. By post 25, those two articles had 40+ internal links pointing at them from inside the site. They still outrank most of our newer content today because of that compounding.
A rough benchmark: aim for 2 to 4 internal links per post once you clear 10 published articles. Fewer than that and you're an island site. More than 6 or 7 on a post under 1,500 words and you're diluting, not helping.
Concrete structure to use right now:
- Pick 3 spine posts. These get linked to from nearly everything.
- Every new post links back to at least 1 spine post, in-sentence, not in a list.
- Every new post gets at least 1 link added to it from an older post within a week of publishing. Don't let posts launch as orphans.
- Skip categories and tags as a linking strategy. They're thin, duplicate, and Google treats them as low value on small sites.
- Revisit your spine quarterly. If a newer post outperforms one of the original three, promote it.
The most common mistake is linking by topic instead of by intent. People link "dog food" posts to other "dog food" posts because the keyword matches, not because the reader actually benefits from going there next. On a 20-post blog I audited last year, half the internal links pointed from a shallow intro post to another shallow intro post. Nobody was ever sent to the piece that would actually move them toward buying or subscribing. Link toward your best, most complete content, not toward whatever shares a tag.
On the $2.2B infrastructure project I handled marketing for, we didn't have a blog with hundreds of posts either, we had maybe 25 explainer pages for a technical audience. We used the same spine approach: 3 core explainer pages got linked from every press release, every FAQ, every update. Those 3 pages carried the SEO weight for the entire site for two years before we had enough volume to build real topic clusters.
Takeaway: don't build a cathedral for 18 posts. Pick 3 spine posts, link new content to them on purpose, and make sure nothing you publish sits there alone with zero internal links pointing at it. That's the whole strategy until you have enough posts to actually cluster.
