How to Write a Blog Post for KS3 English

A blog post is a piece of non-fiction writing addressed directly to an audience — informal in tone, opinionated by nature, and structured to hold a reader's attention from the first sentence. At KS3, writing a blog tests your ability to shape voice, develop a point of view, and use layout features to guide a reader.

What makes a blog post different from other non-fiction forms?

A blog occupies interesting middle ground: more personal than a newspaper article, more structured than a diary, more conversational than an essay. Its defining features are:

Directly addressed to the reader — "you" appears naturally throughout.

A clear viewpoint — bloggers do not sit on the fence. They have opinions and express them.

Accessible and engaging language — informal register, occasional humour, concrete examples.

Visible layout features — subheadings, short paragraphs, and white space are expected.

A sense of personality — readers follow a blog because they like the voice, not just the content.

In an exam, a blog that reads like a formal essay with subheadings added will not score highly. The voice must genuinely feel like a person talking to another person.

How should you structure a blog post?

A blog post is not a five-paragraph essay, but it does have a clear shape:

Section | Purpose | Typical length
Title / headline | Grab attention; signal the topic | One short, punchy line
Opening hook | Pull the reader in immediately | 1–2 sentences maximum
Main body | Develop your viewpoint through 3–4 sections, each with a subheading | 200–350 words
Conclusion | Leave the reader with something to think about — or a call to action | 1–2 short paragraphs

Keep paragraphs short — rarely more than four sentences. Long, dense blocks of text put blog readers off immediately.

What tone and register should a blog post use?

The register should be informal but considered. "Informal" does not mean careless — it means the writer has chosen to address the reader as an equal rather than a subordinate.

Characteristics of a strong blog voice:

Contractions: "it's", "don't", "you'll" — all natural in a blog.

Rhetorical questions: "Have you ever thought about why...?" draws the reader into the argument.

Inclusive language: "We all know the feeling when..." creates a sense of shared experience.

First person: "I think", "In my view", "I've always believed..." — opinion is central to blogging.

Occasional humour or wit: used carefully, it makes serious points more memorable.

What to avoid: heavy jargon (unless the blog is for a specialist audience), text speak or internet slang (except very sparingly for effect), and tone-deaf formality ("It would appear that one might observe...").

How to write an effective blog opening

The opening is everything. Readers decide within two sentences whether to continue. Strong blog openings:

Start with a bold opinion: "School uniform has nothing to do with discipline and everything to do with control."

Start with a surprising fact or statistic: "One in five teenagers says they don't feel welcome in a library. That statistic should embarrass everyone."

Start with a question: "When did we decide that reading for pleasure was something to feel guilty about?"

Start with a brief anecdote: "Last week, someone told me they'd never finished a book. Not because they couldn't — because nobody had ever shown them how to start."

The weakest blog opening is a vague scene-setter: "In today's modern world, many people often wonder about..." Delete this kind of opening every time.

What layout features are expected in a blog post?

At KS3, demonstrating awareness of form is a mark of a sophisticated writer. Blog-specific layout features include:

A clear title at the top — punchy, memorable, specific.

Subheadings between sections — they signal structure and help the reader navigate.

Short paragraphs with white space between them.

Italics or bold for emphasis — used sparingly.

An author name or sign-off at the end (informal: "— Maya, Year 9 Book Club").

In a handwritten exam response, indicate subheadings by underlining them. You cannot reproduce all digital features on paper, but signalling that you are aware of them is enough.

Worked example: weak vs strong blog opening

Weak: In this blog post I will be writing about social media and whether it is good or bad for young people. There are many different views on this topic.

Strong: I've checked my phone four times since I started typing this sentence. That's the problem — and also, weirdly, the reason I keep coming back. Social media is the most compelling trap we've ever built for ourselves, and most of us walked into it smiling.

The second version has an opinion, a personality, a technique (the self-referential observation), and a central tension — all in three sentences.

Frequently asked questions

Does a blog post need a conclusion?

Yes, though not a formal summary. A blog conclusion typically does one of three things: poses a final question to the reader ("So — are you going to try it?"), offers a call to action ("Share this if you agree, argue back if you don't"), or leaves the reader with a final image or thought that echoes the opening. A conclusion that merely repeats the introduction is weak; a conclusion that reframes it is strong.

Can I use subheadings in an exam blog post task?

Yes — and you should. Subheadings signal genre awareness and structure. In a handwritten exam, underline them to mark them clearly. Make your subheadings engaging and specific rather than generic: "Why social media affects sleep" is better than "Point 2".

How informal can the language be?

Informal, but controlled. Occasional contractions, rhetorical questions, and direct address are appropriate. Heavy slang, text speak, or deliberate grammatical errors for comic effect should be used very sparingly and only if you can control the effect precisely. The examiner should always feel that you are in command of the register, not that you have simply forgotten to write formally.

What topics are blogs typically about in KS3 exam tasks?

Topics vary, but common KS3 blog tasks include: writing a blog about a hobby or interest, arguing a position on a school or social issue, responding to a text from the reading section, or writing a personal response to an experience. The form — not the topic — is what the examiner is assessing.
