What Actually Makes a Tech Blog Post Good

Write for one specific person

Picture one reader - say, someone comfortable with JavaScript but who's never touched TypeScript generics. The moment you know exactly who you're writing for, decisions about tone, depth, and which examples to use become a lot easier to make.

Outline before you write a single sentence

Take ten minutes and list the three to five things this reader absolutely needs to walk away understanding. That short list becomes your headings, and it keeps the whole piece from wandering off track halfway through.

Use code that actually runs

People copy your snippets straight into their own projects. If a snippet doesn't run, you've lost their trust instantly. Test every example somewhere real before you hit publish.

Edit for length before you edit for polish

On the first editing pass, cut anything that doesn't move the reader closer to understanding the point. Longer isn't better - a tight 600-word post that fully answers the question beats a 2,000-word one that meanders around it.

Leave them somewhere to go next

End with something concrete: a link to the next post in the series, a small exercise, or a pointer to the official docs. A reader who knows their next step is far more likely to come back.
