Workflow overview

Posting daily fails for a boring reason: deciding what to post is a separate act of creativity from making it, and doing both every morning is exhausting. Batching separates the two.

This workflow produces a week at a time. You define the brand voice once, generate seven varied post concepts against a content mix that prevents the account becoming an advert, then produce the visuals and captions in a single design session.

The content mix rule matters more than the prompts. Seven promotional posts in a row kills reach; a mix of teaching, proof, personality and offer is what keeps an audience.

Goal

Create seven days of on-brand, non-repetitive social content in one sitting, so posting stops being a daily decision.

Best for: Small business owners, freelancers, creators and student societies running their own social accounts.

Step-by-step guide

Work through the steps in order. Every prompt is copy-and-paste ready — swap the bracketed parts for your own details.

1

Define the brand brief once

ChatGPT 4 min

Spend four minutes here and reuse it every week. Give ChatGPT your audience, tone, visual style and the things you never want to sound like. Save the result as a saved prompt or custom instruction so future weeks start from the same voice rather than drifting.

Prompt

Create a reusable social brand brief for [BUSINESS]. Inputs: what we sell [X], who buys it [Y], what makes us different [Z], our three brand colours [HEX], our tone in three words [A, B, C], and three accounts whose style we admire. Return: 1. A voice guide: 5 rules, with a do and don't example for each 2. Five recurring content pillars we can post about indefinitely 3. Ten phrases we should never use 4. A visual style description in one paragraph, usable as the base of every image prompt Keep it concrete enough that a stranger could write in our voice from it.

What you should get back

A reusable brief with five voice rules, five content pillars, a banned-phrase list, and a visual style paragraph you will paste into every image prompt.

2

Generate a week of post concepts

ChatGPT 4 min

Ask for the week as a planned mix, not seven random ideas. Specifying the ratio of educational, proof, personality and promotional content is what stops the account reading like a billboard. Ask for the hook line separately — the first line is what decides whether anyone reads the rest.

Prompt

Using the brand brief, plan seven days of content for [PLATFORM(S)]. Content mix: 3 educational, 1 social proof, 1 behind-the-scenes, 1 engagement/question, 1 promotional. For each day give: - Day and content pillar - Format: single image / carousel / reel / text - Hook: the first line, under 12 words, that stops the scroll - Core idea in one sentence - Why this earns attention from [AUDIENCE] No two posts may use the same hook structure. Avoid every phrase on the banned list.

What you should get back

A seven-day plan with varied formats and hooks, each tied to a content pillar and justified by audience value rather than posting for its own sake.

3

Write captions, hashtags and the carousel outline

ChatGPT 5 min

Generate all the text in one pass so the voice stays consistent across the week. Hashtags should mix reach levels — a handful of large tags plus several niche ones performs better than ten enormous ones you will never rank in.

Prompt

For each of the seven posts, write: - Caption: hook in line one, line break, 2–4 short lines of value, one clear CTA. Max 120 words. - Hashtags: 8 per post — 2 broad (over 500k posts), 4 mid (50k–500k), 2 niche or local - Alt text for accessibility, under 125 characters Then expand the carousel post into a slide-by-slide outline: 7 slides, each with a headline under 8 words and one supporting line, ending on a CTA slide. And write one reel concept: hook line, three-beat structure, on-screen text per beat, suggested audio style, and total length under 25 seconds.

What you should get back

Seven captions with tiered hashtags and alt text, a seven-slide carousel outline, and a reel script broken into three beats with on-screen text.

4

Generate the image prompts and design in Canva

Canva 4 min

Ask for image prompts that all inherit the same visual style paragraph — that shared base is what makes a grid look designed rather than assembled. Generate or select the visuals in Canva, then use Magic Resize to produce feed, story and portrait versions in one action.

Prompt

Write an image generation prompt for each of the seven posts. Every prompt must: - Begin with our visual style paragraph so the week looks cohesive - Describe one clear focal subject, not a busy scene - Specify composition, lighting and mood - Leave deliberate negative space for the headline text - Avoid text inside the image itself - End with: square 1:1 format, high detail, no watermark Then tell me which two posts would be stronger with a real photo instead of a generated image, and what to photograph.

What you should get back

Seven cohesive image prompts plus honest guidance on where a real photo will beat a generated one — usually behind-the-scenes and social proof posts.

5

Finish in Adobe Express and schedule the week

Adobe Express 3 min

Use Adobe Express for quick animation, background removal and resizing into stories and reels covers. Then load everything into your scheduler with the posting times generated below, so the week publishes itself and you spend your time replying to comments instead of making posts.

Prompt

Build a posting schedule for [PLATFORM] targeting [AUDIENCE] in [TIMEZONE]. Give me: day, time, format and the single metric I should judge that post on. Assume the audience is [students / small business owners / local customers] and explain the reasoning behind each time slot in one line. Add a 10-minute daily engagement routine for the first hour after posting.

What you should get back

A seven-row schedule with times, formats and a success metric per post, plus a short daily engagement routine that materially improves reach.

Copy-and-paste prompt library

Every prompt used in this workflow, in one place. Tap copy and paste straight into your tool of choice.

Prompt 1 — Brand brief

Create a reusable social brand brief: 5 voice rules with do/don't examples, 5 content pillars, 10 banned phrases, and a one-paragraph visual style description usable as the base of every image prompt.

Prompt 2 — Weekly content plan

Plan seven days of content with a mix of 3 educational, 1 social proof, 1 behind-the-scenes, 1 engagement, 1 promotional. Per day: pillar, format, a hook under 12 words, core idea, and why it earns attention. No repeated hook structures.

Prompt 3 — Captions and hashtags

For each post write a caption (hook line, 2–4 value lines, one CTA, max 120 words), 8 tiered hashtags (2 broad, 4 mid, 2 niche) and alt text under 125 characters.

Prompt 4 — Carousel outline

Expand this idea into a 7-slide carousel: each slide a headline under 8 words plus one supporting line, building an argument, ending on a CTA slide. Slide one must work as a standalone hook.

Prompt 5 — Reel script

Write a reel under 25 seconds: hook line, three-beat structure, on-screen text per beat, suggested audio style, and the visual action in each beat. The first two seconds must state the payoff.

Prompt 6 — Image prompt set

Write seven image prompts, each beginning with our visual style paragraph, one clear focal subject, specified composition, lighting and mood, deliberate negative space for headline text, no text in the image, square 1:1, high detail.

Prompt 7 — Repurpose the winner

This post performed best: [PASTE]. Generate five variations that keep the winning angle but change the format, hook and example, so I can run it again without repeating myself.

Expected output examples

Day 2 concept

Pillar: Educational · Format: Carousel · Hook: "Your invoices are late for one boring reason" · Idea: the three-line payment terms sentence that cuts late payments · Why: the audience's most common cash-flow frustration.

Caption

Your invoices are late for one boring reason. They don't say when payment is due. "Net 30" is not a date. "Due 14 August" is. Add the date, the amount, and one payment link. Which of the three do your invoices miss?

Image prompt

[Style paragraph] A single ceramic coffee cup on a pale linen surface, soft morning side light, muted teal accents, generous negative space in the upper third for a headline, calm and uncluttered, square 1:1 format, high detail, no watermark.

Schedule row

Wednesday · 12:15 local · Carousel · Metric: saves. Midday works because the audience checks phones at lunch, and carousels earn saves rather than likes.

Real-world example

Independent bike shop, one owner, no marketing budget

The shop posted sporadically — usually a photo of a bike with the price — and reach had been falling for months.

Running the brief step exposed the problem instantly: every post was promotional. The generated week replaced four of those with maintenance tips, one behind-the-scenes repair video and a question post about winter commuting.

Batching took 25 minutes on a Sunday evening instead of ten scattered minutes a day. Within six weeks the maintenance carousels were being saved and shared locally, and the shop's most common in-store line became "I saw your post about brake pads" — which no amount of price posts had ever produced.

If you're a student

Running a society, club or personal portfolio account? The same brief-and-batch approach means posting stops competing with coursework. Batch on Sunday, engage for ten minutes a day, done.

If you run a business

Keep a running note of which hooks earn saves and comments, then feed the winners into the repurpose prompt each month. After a quarter you are no longer guessing what your audience responds to.

Best practices

  • Write the brand brief once and reuse it — consistency comes from the brief, not the prompts.
  • Enforce a content mix. More than one promotional post in seven suppresses reach and trust.
  • Batch the whole week in one sitting; daily decisions are what cause you to stop posting.
  • Base every image prompt on the same visual style paragraph so the grid looks intentional.
  • Use real photos for behind-the-scenes and proof posts — generated images undermine authenticity there.
  • Spend the first hour after posting replying to comments; it does more for reach than the caption did.

Common mistakes

  • Posting seven adverts in a row

    Audiences follow accounts for value, not offers. Teaching content is what earns the right to sell on day seven.

  • Generic AI images with visible artefacts

    Hands, text and logos are still unreliable. Keep the subject simple and check every image before publishing.

  • Ten enormous hashtags

    Broad tags bury you instantly. Mid-size and niche tags are where small accounts are actually discovered.

  • Scheduling and disappearing

    Scheduled posts with no engagement underperform. Ten minutes of replies beats a perfect caption.

Variations

Single-platform deep dive

Generate the week for one platform only, in its native format — LinkedIn text posts, TikTok scripts or Pinterest pins. Cross-posting the same asset everywhere always underperforms.

Month in one sitting

Run the plan prompt four times with a different theme per week, then batch all design work in a single two-hour session.

Personal brand version

Swap product pillars for expertise pillars and add a story-based pillar. Personal accounts convert on point of view, not features.

Frequently asked questions

Will AI-generated images hurt my reach?

Not inherently, but obviously generic visuals reduce trust. Use generated images for concept and illustration posts, and real photography for anything claiming to show your actual work, team or premises.

How many hashtags should I use?

Eight to twelve on Instagram, one or two on LinkedIn, three to five on TikTok. Tiering by size matters far more than the count.

Can I use this for multiple platforms at once?

Yes, but ask for platform-native versions rather than reposting identical content. The core idea can repeat; the format and hook should not.

How long before I see results?

Expect six to eight weeks of consistent posting before patterns are readable. Judge saves, shares and comments early — follower count is the slowest and least useful signal.

Do I need paid Canva or Adobe Express?

The free tiers cover the essentials. Paid Canva mainly adds Magic Resize convenience and a larger asset library, which saves time once you are batching every week.
