Social media content: what to post on Facebook, Instagram, LinkedIn, and TikTok

Why not to post the same content everywhere

When starting with social media marketing, it's tempting to create a single post and distribute it across all channels simultaneously. However, each platform serves a different purpose and reaches people in varying states of mind. What works on TikTok might get lost on LinkedIn—and vice versa.

The good news is that you don't need to create completely original content for each network. One idea can be cleverly adapted for multiple platforms. The key term is 'adapt', not 'copy'.

Facebook: broad reach and community building

Facebook has the widest and usually the oldest audience of the four networks. It's ideal when you want to reach a large, age-diverse group of people.

What works here:

• Short videos and Reels — increasingly becoming the most viewed format

• Photos and albums — easy to produce and work well for products and events

• Links to your website or blog — to drive visitors to your pages

• Groups — a perfect tool for building a community around your brand

Ideal posting frequency is 3–5 posts per week. More isn't necessarily better — if you post too often, individual posts compete, and each reaches fewer people.

Instagram: a visual showcase

Instagram is built on several pillars, each serving a different purpose:

• Reels — the main engine of reach. The algorithm shows them even to those who don't follow you yet. Great for quick tutorials, product showcases, or 'before and after' demonstrations.

• Carousels (multi-image posts) — drive engagement and saves. Suitable for tips, step-by-step guides, or overviews. People save them to revisit later.

• Stories — build daily contact with those who already follow you. Polls, behind-the-scenes, quick news.

• Static photos — fastest to create and good for profile aesthetics, but have the lowest reach.

Proven frequency is about 3–5 feed posts per week plus regular Stories. For small businesses, a mix of several Reels, a few carousels, and one to two photos per week is worthwhile.

LinkedIn: a space for expertise and B2B contacts

LinkedIn is a professional network. People come here for work, industry, and connections—not for entertainment. It's suitable for businesses selling to other businesses and for anyone wanting to build a reputation for expertise.

What works best here:

• Document posts (carousels in PDF format) — long-standing as one of the highest-engagement formats

• Text posts with a strong opening — a short, catchy first line decides whether the reader clicks 'see more'

• Polls — a simple way to spark discussion

• Video — its significance is growing here too

Best results come from 2–5 posts per week, specifically on working days. Traffic is minimal here over the weekend.

TikTok: discovery and viral potential

TikTok is based on short vertical videos and discovery. Thanks to the 'For You' page, even a small account can reach thousands of people who didn't know it before — other networks do not offer this to the same extent.

What works here:

• Short videos — under 60 seconds with a clear punchline

• Current trends and sounds — but always with your own twist, not blind copying

• Authenticity — raw mobile phone video here often beats polished advertising

• Educational content — short 'how-to' guides

TikTok rewards regularity more than other networks. Many companies manage 3–7 videos a week, and those wanting to grow faster post almost daily. However, a sustainable pace that doesn't compromise quality is more important than quantity.

Quick overview: how often and what to post

Maximising one idea

The most efficient approach is to take one topic and adapt it for each network in its own language. One guide can become:

• A Reel and TikTok video with a showcase

• A carousel on Instagram and a document post on LinkedIn detailing steps

• A text post on Facebook linking to a more detailed article

Instead of creating four times the content, you maximise one idea and still appear natural everywhere. Choose one or two networks where your audience is, and focus on them properly — this works better than spreading yourself thin everywhere.
