If I were starting an Instagram and a LinkedIn presence from zero today, I would pick one audience, publish on a fixed schedule, and design every post to be saved or sent to someone rather than merely liked. Instagram's ranking leans on sends and views, and LinkedIn's on dwell time and saves, according to current industry analyses. Here is the 90-day plan I'd run, as of 30 September 2026.
Key Takeaways
- Choose one specific audience and one promise before you post anything. Broad accounts stall.
- On Instagram, aim for sends per reach and originality. On LinkedIn, aim for saves and reading time.
- Personal profiles get far more LinkedIn distribution than company pages, according to one analysis, so build the founder or team voice.
- Consistency beats intensity: a schedule you can hold for 90 days beats a sprint you abandon.
- Review weekly, change one variable at a time, and don't trust any single "algorithm hack".
What I Actually Know From Experience
I worked on social-led organic growth at Masai School, where Instagram grew from about 26K to 117K followers and LinkedIn from about 50K to 200K. That was a team effort inside an edtech company with an existing brand, budget and a large audience of learners, so I would not promise anyone the same curve from zero. What transfers is the method: a clear audience, repeatable formats, and relentless iteration on what people saved and shared.
What the Platforms Reward Right Now
I rely on third-party analyses here because neither platform publishes a full ranking recipe. Treat every figure as reported by its source, and expect change.
Sprout Social's 2026 explainer says sends per reach, meaning how often people share a post privately by direct message, is now a leading indicator of content value. It also says views have become the primary metric across formats, and that Instagram penalises aggregator accounts that repost without adding value, often showing the original creator instead. Secondary signals include watch time (especially past the first three seconds of a Reel), relationships and engagement actions (Sprout Social).
SocialPilot's September 2026 write-up says no confirmed distribution change was announced for the month, and that the March 2026 "360Brew" model and a depth-focused approach remain the framework. Among its claims: saves carry about five times the weight of a like, document or carousel posts perform strongly at 8-12 slides, external links reduce reach, and personal profiles get most of the feed distribution compared with company pages. It cites Richard van der Blom's analysis of 1.8 million posts for declines in organic reach (SocialPilot). These come from a third-party blog summarising other analyses, so I hold them loosely, but they agree with what I see in practice.
Step 1: Choose Your Audience and Promise
Write one sentence: "I help [specific person] do [specific outcome] with [my angle]." For an edtech account that might be "career switchers into data roles". Anything vaguer produces vague content.
List five recurring questions that person asks. Those are your content pillars. If you can't list five, you don't know the audience well enough; talk to ten of them first.
Step 2: Set Up Profiles That Convert
LinkedIn profile
- Headline says who you help and how, not just a job title.
- Banner states the promise.
- Featured section links to your best proof.
- About section is written in first person and opens with the reader's problem.
Instagram profile
- Name field includes the keyword people would search.
- Bio: who it's for, what they get, one link.
- Three to four highlights: start here, proof, FAQs.
- Pin your three best posts.
Step 3: Build a 90-Day Plan
| Weeks | Goal | ||
|---|---|---|---|
| 1-2 | 3 Reels, 2 carousels per week, test formats | 3 text or carousel posts per week | Find formats that get saves and sends |
| 3-6 | Double down on the top two formats | Add one document post per week | Establish rhythm |
| 7-10 | Add a series with a recurring name | Comment daily on 5 relevant posts | Build recognisable identity |
| 11-13 | Repurpose best posts, collaborate | Newsletter or long post from top themes | Convert attention into subscribers or leads |
Adjust frequency to what you can sustain. Three good posts beat seven rushed ones.
Step 4: Make Posts Worth Saving and Sending
Instagram: design for sends
Ask of each post: would someone send this to a friend with "this is you" or "you need this"? Formats that pass: checklists, myth-versus-fact, relatable moments, specific mini-guides. Make the first second unmistakable, keep the value dense and end with a reason to share ("send this to whoever is applying this month").
LinkedIn: design for depth
- Lead with a specific line, not a warm-up.
- Use a carousel of 8-12 slides for how-tos, one idea per slide.
- Put links in a comment or a separate post if you're concerned about the reported reach penalty.
- Write from a real experience with a real number, even a small one.
Original beats recycled
Both platforms are described as penalising unoriginal material. SocialPilot reports lower reach for AI-generated content without original perspective, and Sprout says Instagram deprioritises reposters. I use AI for outlines and edits, never for the idea or the lived detail.
Step 5: Engage Like a Person
Reply to every comment in the first hour where you can. Leave thoughtful comments on posts from people your audience follows. Send a short voice or text reply to genuine DMs. This is slow, unglamorous work, and it's where early followers come from.
Step 6: Review Weekly
Every Friday, 30 minutes:
- List your top three posts by saves and sends (not likes).
- Note the format, hook and topic.
- Decide one change for next week.
- Retire one format that isn't working.
Change one variable at a time or you'll learn nothing.
A Sample Week
To make this concrete, here is a week I would run in month two. On Monday, an Instagram carousel answering one pillar question. On Tuesday, a LinkedIn document post from the same idea, rewritten for a professional reader rather than pasted. On Wednesday, a Reel showing one step live. On Thursday, a text post with a small number from real work. On Friday, review saves and sends, then answer comments. Notice that one idea feeds four posts. Repurposing across platforms saves time, but rewrite the hook and format for each, because an Instagram caption pasted into LinkedIn reads as exactly that.
Step 7: Turn Followers Into Something
Followers are not the goal. Decide early: newsletter signups, demo calls, applications, or job enquiries. Give each platform one call to action and track it with a UTM link.
Common Mistakes
- Posting for everyone. Nobody feels addressed.
- Copying trending audio and formats with no point of view.
- Optimising for likes, which correlate weakly with the actions platforms describe as valuable.
- Buying followers or joining engagement pods. It corrupts your data and can hurt reach.
- Quitting at week three, exactly when the plan starts to work.
What I Would Not Promise
Nobody can promise a follower number in 90 days. My realistic expectation from zero: by day 90 you'll know your best formats, have a small engaged audience, and have a system. That's a foundation, not a finish line.
FAQ
How often should I post on Instagram and LinkedIn?
Start with three to five posts a week on each and hold it for 90 days. Sustainability matters more than volume, and most third-party guides suggest consistency over frequency.
What matters most on Instagram in 2026?
Per Sprout Social, sends per reach and views, plus originality. Design posts people would send privately to someone.
What matters most on LinkedIn?
Reported signals include saves, dwell time and personal-profile posting. SocialPilot says no confirmed distribution change was announced for September 2026.
Should I post as a company page or a personal profile?
Analyses cited by SocialPilot say personal profiles receive most feed distribution. I'd use both, but lead with a founder or team voice.
Do external links hurt LinkedIn reach?
Reported analyses say yes, by roughly 60%. I can't verify the figure, so test it: publish the post without a link and put the link in the first comment.
Can I use AI to write posts?
Use it for structure and editing, not for the idea. Reports say generic AI content gets less reach, and it rarely earns saves anyway.
How long until I see results?
Usually weeks before patterns emerge and months before compounding. I wouldn't promise a number.
Is it worth growing both platforms at once?
Only if you can keep both up. Otherwise start with the one where your audience already spends time, then repurpose.
What did work at Masai School?
Clear audience focus, repeatable formats and constant iteration, within a team and brand that already existed. Results from one company don't guarantee yours.
