The default advice for growing an online business is to be everywhere: Twitter, LinkedIn, Instagram, Threads, Bluesky, TikTok. Post daily. Engage relentlessly. Cross-promote.
In practice, most solo operators and small teams spread themselves so thin across platforms that they can’t tell which channels actually deliver. They post sporadically, track inconsistently, and burn hours context-switching between apps with no clear return.
The contrarian take: you should be active on two social platforms, maybe three. Any more than that and you’re optimizing for presence instead of results.
The cost of multi-platform distribution
Every platform you maintain has a real time cost. You need to:
- Adapt content format and tone for each audience
- Monitor replies, DMs, and mentions
- Track referral traffic and conversions separately
- Stay current on algorithm changes and feature rollouts
- Manage posting schedules that don’t overlap poorly
A single post on LinkedIn might take 10 minutes to write and format. The same core idea reshaped for Twitter threads, Instagram carousels, and TikTok scripts can easily consume two hours. If you’re posting three times a week across four platforms, that’s 24 hours a month just on content creation—before engagement, before analytics.
And unlike email, where you own the relationship, social platforms can change reach overnight. You’re renting attention, and the lease terms shift without notice.
How to pick your two platforms
Start with where your revenue actually comes from. Open your analytics tool—Google Analytics, Fathom, Plausible, whatever you use—and filter traffic sources for the last 90 days. Look at:
- Sessions from each social platform
- Conversion rate (email signups, purchases, course enrollments)
- Time on site—are visitors sticking around or bouncing?
Most operators discover that 80% of their social-driven conversions come from one or two platforms. Often it’s LinkedIn for B2B, Twitter for tech audiences, or Instagram for visual products. The other four platforms deliver sporadic traffic that rarely converts.
If you don’t have 90 days of data, run a 30-day test. Post consistently on your current platforms and track everything with UTM parameters (?utm_source=twitter&utm_medium=social&utm_campaign=july). The platform that delivers qualified traffic wins. The rest are candidates for shutdown.
What about discovery and reach?
The common objection: “But I need to be everywhere for discovery. What if my audience is on Platform X?”
Discovery is overrated for most online businesses. If you’re running a newsletter, a course, or a productized service, your growth comes from being consistently valuable in one place, not sporadically present in six. A weekly LinkedIn post that gets 40 comments and five email signups beats a daily TikTok habit that generates 2,000 views and zero conversions.
The operators who grow fastest pick one primary platform and one backup. Primary gets 70% of effort: original content, deep engagement, network building. Backup gets 30%: reposts, highlights, low-effort syndication. Everything else gets abandoned or automated into oblivion.
Tools like Publer can help with cross-posting if you want a minimal presence elsewhere, but even then, you’re better off focusing energy than fragmenting it.
When to add a third platform
Add a third platform only when:
- Your two primary channels consistently deliver 20+ conversions per month each
- You have a specific, proven audience segment that only exists on the new platform
- You can hire or delegate content creation so your personal time doesn’t increase
Until then, double down on what works. A single platform with deep engagement and clear attribution beats shallow presence across the entire social web.
