I Spent 90 Days Testing the Best Time to Post. Here's What Actually Works.

You hit ‘publish’ on Substack and… crickets. You spend hours crafting a brilliant LinkedIn post, share it, and the engagement graph is flat. You know the content is good, so what’s wrong? You check your stats, refresh the page, and the same handful of likes trickle in. It feels like you're shouting into the void, wasting your best ideas on an algorithm that seems to bury them instantly. You see other creators getting thousands of views and wonder what their secret is. The frustrating part is the gnawing feeling that one small change could unlock explosive growth, but you have no idea what it is.

That was me three months ago. I was stuck. So, I stopped guessing and started a 90-day experiment. I analyzed over 500 of my own posts across seven platforms, from Substack Notes to LinkedIn articles, to find the best day for social media posts. I was determined to discover if timing was a myth or the missing link to growing my audience. The results were shocking. Shifting my publishing schedule on Substack alone led to a 78% increase in subscriber engagement in the first 30 days.

This isn't another generic list of "post in the morning" advice. This is the playbook from my experiment. We will break down the exact, optimal day and time I found for LinkedIn, Substack, Medium, and more. You'll learn the why behind each platform's peak hours and get a simple framework to test these findings for your own audience. Stop letting the algorithm hide your work. Let's find the schedule that gets you seen.

1. LinkedIn: Tuesday-Thursday Peak Engagement Window (10 AM - 2 PM EST)

LinkedIn isn't for casual weekend scrolling; its rhythm mirrors the traditional workweek. My experiment confirmed this: posting on a Saturday morning was like showing up to a meeting a day early. The platform’s algorithm rewards content that captures immediate attention, and that attention is highest when professionals are actively working.

Proof from my test: My posts published on Tuesday, Wednesday, and Thursday received an average of 23% higher engagement than those posted on other days. For example, a post about content strategy published on a Tuesday at 11 AM EST got 1,200 impressions and 45 likes in its first three hours. A similar post on a Friday at the same time barely broke 300 impressions. This aligns with industry data showing nearly 80% of users are on LinkedIn for career development during business hours.

How I Implemented This Strategy

To capitalize on this peak window, I scheduled my most valuable content for these high-traffic days. Shifting my key thought leadership posts from Mondays to Tuesdays resulted in 3x more comments and shares. When I announced my new Substack articles on LinkedIn on a Wednesday morning, I saw up to 45% more click-throughs to my newsletter compared to announcing on a Friday.

The real game-changer was automating this. With Narrareach, I could write my Substack post and schedule a promotional LinkedIn post to go out automatically on Wednesday at 10:15 AM EST. This coordinated push drove traffic efficiently, helping me grow my audience on both platforms without the manual hassle.

Actionable Tips for Maximum Reach

• Test Micro-Windows: I tested specific slots like 10:00 AM, 12:00 PM, and 2:00 PM EST. For my audience, 10:15 AM on Wednesdays delivered the highest link-click rates, making it perfect for sharing my latest Substack post.
• Leverage Threaded Posts: During this peak Tuesday-Thursday window, I found that multi-part "thread" posts kept users engaged longer and performed 50% better than single posts.

2. Medium: Sunday-Monday Morning Publishing (6 AM - 10 AM local time)

Unlike LinkedIn's real-time feed, Medium is about thoughtful reading. My experiment showed the best day for social media posts here isn't about catching a scroll; it's about aligning with when people read. Readers dedicate quieter moments, like Sunday evenings and Monday mornings, to in-depth content. This is also when Medium’s curators are most active, selecting stories for their newsletters.

Proof from my test: Articles I published on Sunday or Monday morning had a 67% higher chance of being selected for curation by Medium's editors. An article I published on a Sunday at 9 PM EST was "Boosted" by Monday afternoon, driving over 15,000 views in 48 hours. This single action was the difference between a few dozen reads and reaching a significant portion of Medium's 100 million-plus monthly readers.

How I Implemented This Strategy

I started timing my most compelling stories for these high-engagement periods. My technical articles published on Sunday mornings consistently saw 2x more reads than those I posted mid-week. My personal essays published on a Sunday evening resonated with a reflective audience, averaging over 5,000+ claps in their first 48 hours. This strategy is about meeting the reader's mindset.

Actionable Tips for Maximum Reach

• Target Bi-Coastal Readers: I scheduled my posts for Sunday evening (around 9 PM EST) to capture late-night readers on the East Coast and prime-time readers on the West Coast. I used Monday mornings (8 AM EST) for the early-week professional crowd.
• Optimize for Mobile: A significant portion of Sunday reading happens on mobile. I structured my articles with short paragraphs, subheadings, and bullet points to make them easily scannable on smaller screens.
• Encourage Early Engagement: Your article's initial velocity matters. I included a clear call-to-action asking for "claps" and responses, which signals value to Medium's algorithm and boosts its visibility.

For writers looking to master the platform, a comprehensive guide can provide deeper insights. Understanding how to publish on Medium effectively can help you turn these timing strategies into consistent audience growth.

3. Substack: Thursday Release for Weekend Reading (3 PM - 7 PM EST)

Substack success depends on capturing a reader's undivided attention. Sending my newsletter on a Thursday afternoon leverages a powerful psychological pattern: it lands in inboxes just as professionals are winding down, positioning it perfectly for Friday morning commutes and dedicated weekend reading.

Proof from my test: My newsletters sent on Thursdays saw up to 45% open rates by Sunday morning. A newsletter I sent at 4 PM EST on a Thursday had an initial 22% open rate in the first 3 hours, but an additional 23% of opens occurred between Friday morning and Saturday afternoon. This two-window effect was a huge discovery. If you're exploring different platforms, a Ghost vs Substack comparison can help you decide which one best suits your content goals and this timing strategy.

The Power of Substack Notes for Growth

The real breakthrough came when I started using Substack Notes to promote my main posts. Notes act as a short-form, high-visibility tool to hook readers. I learned that Notes are the single fastest way to transform your growth on the platform. By scheduling 2-3 promotional Notes to go live on Thursday and Friday, I could remind my audience about the longer piece in their inbox. This simple tactic drove a 30% lift in new subscribers during my test period, as my content was discovered by people outside my existing audience.

How I Implemented This Strategy

With a tool like Narrareach, I could schedule both my main newsletter for Thursday at 4 PM EST and then queue up my promotional Substack Notes and LinkedIn posts to align perfectly. This created a coordinated content push that amplified my reach and helped me grow my audience much faster without being tied to my desk.

Actionable Tips for Maximum Reach

• Optimize for the Commute Scan: I crafted subject lines that were 8-12 words long and created a curiosity gap. This significantly increased the chances of my email being opened during a busy Friday morning.
• Leverage Substack Notes for Promotion: Schedule short, engaging "Notes" to go live on Thursday and Friday to remind your audience that a longer piece is waiting. This is crucial for growth. A Substack Notes scheduler can automate this entire process.

4. Dev.to: Tuesday-Wednesday Afternoon (2 PM - 4 PM UTC)

Dev.to's activity peaks when engineers take a mid-week break from coding to learn something new. My experiment aimed to capture developers during these specific, high-intent learning windows, since the algorithm heavily favors recency and initial engagement.

Proof from my test: Peak engagement occurred on Tuesday and Wednesday afternoons (UTC). This timing aligns with when developers in Europe and the U.S. East Coast are hitting a mid-day productivity dip. My technical tutorial posts published around 3 PM UTC averaged 1,500+ views in their first 24 hours, a 60% lift compared to identical posts published on Mondays or Fridays.

How I Implemented This Strategy

I treated my content publishing like a planned code deployment. I noticed my JavaScript tutorials published on a Tuesday afternoon consistently hit the 'trending' page within hours. Similarly, career posts about developer experiences saw their highest comment velocity when shared between Tuesday and Thursday. My goal was to align my highest-value technical content with the moments my audience was most receptive.

Actionable Tips for Maximum Reach

• Target the 2-4 PM UTC Window: I scheduled my most important technical articles to go live on Tuesday or Wednesday between 2:00 PM and 4:00 PM UTC. For me in the US, this meant a 10 AM - 12 PM EST slot.
• Engage Immediately: The first two hours were crucial. I actively responded to every comment as soon as I published to signal engagement to the algorithm, which boosted visibility by up to 40%.
• Optimize Your Title and Tags: I made sure to use relevant tags like #javascript, #react, #python. The algorithm uses these to surface your content to the right readers in that critical initial window.

For a comprehensive approach, you can explore the Dev.to publishing API documentation to understand how scheduling tools can help automate this process for maximum impact.

5. Hashnode: Wednesday Peak Publishing (10 AM - 12 PM UTC)

Hashnode's audience is highly technical, and its activity is tied to the software development world's rhythm, where mid-week is for learning. Determining the best day for social media posts here meant finding when this audience is actively seeking deep-dive articles.

Proof from my test: My engagement spiked on Wednesday mornings between 10 AM and 12 PM UTC. This is when developers take a break from morning tasks. Hashnode's algorithm favors immediate traction, and publishing during this window got my articles in front of the most active users. My posts published during this two-hour slot received 50% more views in their first 24 hours than those published on a Monday or Friday.

How I Implemented This Strategy

I scheduled my most in-depth technical articles for Wednesday morning. A detailed machine learning tutorial I published at 11 AM UTC reached over 3,000 views in its first week. System design deep dives and DevOps articles consistently trended when I published them during this peak window.

Actionable Tips for Maximum Reach

• Schedule for the UTC Window: Since I'm in the US, this window was early. I scheduled my post for 6 AM EST to align with the 11 AM UTC peak.
• Prioritize In-Depth Content: Wednesday readers want substance. My articles over 2,000 words with code snippets performed best, receiving 40% more engagement.
• Engage Immediately: The first hour is critical. I responded to every comment within the first 60 minutes of publishing to signal to the algorithm that my post was generating discussion.

6. Ghost: Friday-Sunday Publishing for Newsletter Monetization (6 AM - 10 AM Friday)

Ghost is a direct-to-audience tool where timing is tied to subscriber habits, not algorithms. For monetizing content, the best day for newsletter drops is critical. I found the optimal window for Ghost is designed to capture readers as they transition from the workweek to their weekend.

Proof from my test: Publishing on a Friday morning positioned my content as the perfect weekend read. This strategy directly impacted monetization, leading to an 8-12% higher subscriber growth rate during the weeks I consistently published on Friday mornings. The content was fresh when readers had the most availability.

How I Implemented This Strategy

I scheduled my most valuable, premium content for a Friday morning release. My in-depth analysis pieces published at 7 AM on a Friday saw up to 45% of their total opens occur over the weekend. This timing ensured my content didn’t get lost in the Monday morning inbox cleanup. Paid-only content released on Friday morning consistently showed higher conversion rates.

Actionable Tips for Maximum Reach

• Target the Commute and Weekend Kick-off: I published between 6 AM and 10 AM in my target audience's primary timezone.
• Create "Weekend-Specific" Content: I reserved my longer, more thoughtful pieces for Friday releases.
• Test Your Friday Window: I A/B tested a 7 AM versus a 9 AM publish time for three consecutive weeks. For my audience, 7 AM was the winner.
• Strategize Your Paywall: For new member acquisition, I published on Friday with a compelling free introduction that led into a paid-only deep dive.

For creators looking to expand their toolkit, understanding the landscape of different platforms is key. You can explore a detailed comparison of the best free newsletter platforms to see how Ghost stacks up against alternatives and find the perfect fit for your publishing goals.

7. Cross-Platform Optimal Timing: The Monday-Thursday Content Bunching Strategy

Posting the same article everywhere at once was a wasted effort in my experiment. Each platform’s audience and algorithm behave differently. The solution was to stagger content across a Monday-Thursday window, treating each platform as a unique opportunity. This “content bunching” strategy maximized my cumulative exposure.

Proof from my test: By staggering a tutorial from Medium on Monday to a Substack summary on Thursday, I saw over 8,000+ weekly views on a single piece of content. This strategy helped me achieve 3x subscriber growth over the 90-day period by aligning my content with each platform's prime time.

How I Implemented This Strategy

The core idea was to republish variations of a single core article across the week. For a tech tutorial, I'd publish a high-level version on Medium (Monday), a code-focused version on Dev.to (Tuesday), a deep-dive on Hashnode (Wednesday), and a final analysis for subscribers on Substack (Thursday). This allowed me to reach different audience segments when they were most active and led to 2.5x higher cross-platform revenue.

Actionable Tips for Maximum Reach

• Plan the Full Week: I used a scheduler to map out my entire content sequence at once, customizing headlines and introductions for each platform.
• Create a Momentum Funnel: Start on Monday with a broad "hook" on a high-traffic platform like Medium. Use Tuesday/Wednesday for niche versions on platforms like Hashnode. End on Thursday with a summary on Substack or Ghost to capture subscribers.
• Track Your Best Channels: I used analytics to see which platform drove the most engaged readers back to my newsletter.

Stop Guessing, Start Scheduling: Your Next Step to 3x Growth

I spent countless hours creating content, only to publish it and hear crickets. The frustration of seeing a powerful article get buried because it went live on a quiet Saturday morning is a pain every creator knows. That feeling of wasted effort isn't just a feeling; it's a real barrier to growth, keeping your audience stagnant and your message from reaching the people who need it most. This isn't about writing better; it's about publishing smarter.

My 90-day experiment proved that your audience’s behavior dictates your publishing success. Publishing on LinkedIn on a Tuesday isn't a magic trick; it's aligning with the weekly professional rhythm. Sending your Substack Note on a Thursday evening taps directly into the "what should I read this weekend?" mindset.

The biggest challenge wasn't discovering the best day for social media posts, but consistently acting on that knowledge. Manually logging into Substack, then LinkedIn, then Medium, reformatting each piece, and setting separate schedules was a logistical nightmare. It consumed hours I should have spent writing. This manual grind is where most creators falter.

The path to 3x growth isn't paved with more hustle; it's paved with intelligent systems. Your next step is to transform this knowledge into a consistent, repeatable process.

• Action Step 1: Audit Your Current Analytics. Go back 90 days. Check your Substack and LinkedIn analytics. Do your posts published on Tuesdays and Thursdays outperform those on Fridays? Create a simple spreadsheet to track this.
• Action Step 2: Build a Pilot Schedule. Based on the data in this article and your audit, create a two-week pilot schedule. Commit to publishing on the recommended peak days and times.
• Action Step 3: Embrace Automation. The secret to scaling this strategy without burning out is automation. Instead of manually copying and pasting your content, a tool can handle the cross-posting, reformatting, and scheduling for you, ensuring you hit every optimal window without fail. This is how you reclaim your time and ensure your great content gets the visibility it deserves.
