How to Write a Technical Blog Post That People Actually Read
Most technical blog posts fail at the same place: the opening. They start with a definition, a history of the problem, or a tour of all the things they won’t cover. By the second paragraph, the reader has left. Writing a technical post that holds attention requires treating it less like documentation and more like a conversation with a specific developer who has a specific problem to solve.
Start With the Problem, Not the Solution
The instinct when writing technical content is to front-load context. Explain what the technology is, where it came from, what problem space it addresses. Readers don’t need any of that to stay engaged. They need to believe, within the first two sentences, that this post is going to solve something for them.
The difference between a post that gets read and one that gets closed is whether the opening creates a sense of recognition. “I’ve had that exact problem” is the reaction you’re optimizing for.
What works:
- Open with a scenario — a moment in a debugging session, a decision that needed to be made, a bug that took too long to find
- Open with the consequence of not knowing — what goes wrong, what gets slow, what confuses new engineers on the team
- Open with a surprising statement that rewards the reader for reading further
What doesn’t:
- Dictionary definitions of the technology
- “In this post, we will explore…”
- A summary of everything the post will cover before covering it
Write the opening last. It’s easier to write a compelling hook after you know exactly what you’ve said.
Know Exactly One Reader
Technical writing gets generic when it tries to serve everyone. A post about database indexing written for “developers” is different from one written for “Rails engineers who know SQL basics and are debugging a slow query in production right now.”
The more specific the imagined reader, the more useful the post feels to every reader in that segment — because they feel seen rather than swept up in a broad audience statement.
Before writing, answer these questions:
- What does this reader already know?
- What problem do they currently have, and what have they already tried?
- What would they actually do differently after reading this?
You don’t have to answer these explicitly in the post. But writing with these answers in mind changes the tone, the examples you choose, and the assumptions you build on.
Structure for Scanners and Readers Both
Technical blog readers are not linear. Most people scan headings first, read the sections that look relevant, and may or may not read the rest in order. Your post needs to work for both the scanner and the careful reader.
For scanners:
- Headings that describe the content, not just the concept — “When to Use Counter Caches” beats “Counter Caches”
- Code blocks that show the key point without requiring the surrounding text to understand
- Callout boxes or blockquotes for the one thing you most want them to remember
For careful readers:
- A clear progression of ideas — each section builds on the last
- Explanations that don’t assume knowledge you haven’t established
- A conclusion that synthesizes rather than repeats
The structure that works well for most technical posts: problem → failed approaches or common mistakes → the actual solution → gotchas and edge cases → conclusion. This matches how a developer would think through the problem themselves.
The Code Must Pull Its Weight
Every code snippet in a technical post should either demonstrate something that words can’t, or compress something that would take three paragraphs of explanation. If the code block is there because it “looks like a technical post,” cut it.
The snippets that earn their place:
- Showing the before/after of a change
- Making a subtle difference concrete (argument handling, return semantics)
- Providing something the reader can run immediately
The snippets that don’t:
- Boilerplate that’s necessary but not the point
- Long blocks where the relevant part is three lines at the bottom
- Code repeated with minor variation when one example would do
Comment only the part that isn’t obvious from the code itself. Over-commented code in a blog post implies you don’t trust your examples to be clear.
Write the Way You’d Explain It to a Colleague
The clearest technical writing sounds like the best kind of conversation: direct, specific, and not performing expertise. Complexity of topic doesn’t require complexity of sentence.
Signals that a draft needs simplification:
- Passive voice where active voice works better (“the method is called” vs “you call the method”)
- Hedging language that adds length without adding clarity (“it’s worth noting that,” “it should be mentioned”)
- Abstract nouns where verbs would be cleaner (“make an implementation of X” vs “implement X”)
- Three adjectives where one would do
Read your draft aloud. If you hesitate or have to re-read a sentence to understand it, rewrite it. Spoken clarity is a good proxy for written clarity.
Pro-Tip: Keep a running log of the questions you get asked — in Slack, in code review, in meetings. Each question is a post waiting to be written, because if one person asked it out loud, twenty others had the same question and didn’t ask. The questions that get asked repeatedly in a team are the ones where the documentation or existing blog posts aren’t doing their job. Writing the answer to those questions creates search-engine-discoverable content that serves your future teammates, your external audience, and your own reference.
Conclusion
Technical blog posts that earn readers earn them the same way all good writing does: they understand exactly who they’re talking to, they start at the problem, they respect the reader’s time, and they say one clear thing well. The technical content is necessary but not sufficient. A post can be technically correct and still fail at communication. The developers whose writing gets read and shared write with both halves — the technical rigor and the craft.
FAQs
Q1: How long should a technical blog post be?
Long enough to be complete, short enough to stay focused. For most topics, 800–1,500 words handles a well-scoped concept. Tutorials that walk through a complete implementation can go longer. If you’re over 2,000 words, consider whether you’re covering one topic or two.
Q2: Should I write for beginners or experienced developers?
Write for the most specific audience that makes sense for your content. A post on Ruby Ractors isn’t for beginners — write it for developers who know Ruby and want to understand this specific feature. A broad audience assumption leads to generic content.
Q3: How do I get people to actually find and read my posts?
SEO matters, but the distribution channel that works best for developer content is community: Twitter/X, LinkedIn, relevant Slack groups and Discord servers. Share the post where the people who have the problem you’re solving actually spend time. One well-placed link in the right community beats generic promotion.
Q4: How often should I publish?
Consistency matters more than frequency. Monthly is fine if it’s consistent. A post every six weeks beats three posts in one week and then nothing for four months. Your audience doesn’t expect a publishing schedule — they expect that when you do publish, it’s worth reading.
Q5: Is it okay to write about things I’m still learning?
Yes — with appropriate framing. “Here’s what I learned while figuring this out” is valuable content. Readers who are at the same point in the learning curve find it more relatable than an authoritative reference. Be explicit about what you know versus what you’re still uncertain about.
