Explanation
Social media marketing means using platforms such as LinkedIn, Instagram, YouTube or TikTok to reach and build relationships with your niche. For a small business, the goal is not fame but a steady flow of qualified people who move to your website or email list, where you control the relationship. How herd behaviour on social media affects decisions is covered in the trading psychology course; here we focus on the seller's side.
Choosing platforms
Pick one or two platforms, not five. Ask three questions: where does your niche already discuss its problems? Which format suits your strengths (writing, speaking, visuals)? How many hours per week can you commit for at least six months? A B2B (business-to-business) offer for translators may fit LinkedIn and professional groups better than a video-first platform.
Metrics that matter
- Reach: the number of different accounts that saw a post. Impressions: total views, including repeat views by the same account.
- Engagement: interactions such as likes, comments, shares and saves.
- Engagement rate (by reach) = interactions ÷ reach × 100%. Platforms and tools define it differently, so always use the same definition when you compare.
- Click rate = link clicks ÷ reach × 100%.
- Sign-up rate = sign-ups ÷ link clicks × 100%.
Vanity metrics are numbers that look good but say little about business results, such as follower count or likes alone. Followers can be bought, which breaks platform rules and gives you an audience that never buys. Organic reach (unpaid reach) also depends on platform algorithms that change without notice, which is another reason to move people to your email list.
Labelling advertising in Germany
German unfair competition law (UWG) requires that the commercial purpose of content is recognisable unless it is already obvious from the context. Since a 2022 reform, the law addresses influencer posts explicitly: posts for which you receive money or a similar benefit from another company must be labelled, for example with "Werbung" or "Anzeige". Posts promoting your own products on your own business account are usually recognisable as advertising, but details depend on the case. This is general orientation only; check the current rules or ask a lawyer.
Worked example
Hypothetical example: Lena compares two LinkedIn posts from the same week.
| Post A: funny meme | Post B: invoice checklist | |
|---|---|---|
| Reach | 4,000 | 1,500 |
| Interactions | 120 likes + 15 comments + 10 shares + 15 saves = 160 | 90 |
| Engagement rate | 160 ÷ 4,000 = 4.0% | 90 ÷ 1,500 = 6.0% |
| Link clicks | 20 | 45 |
| Click rate | 20 ÷ 4,000 = 0.5% | 45 ÷ 1,500 = 3.0% |
| Email sign-ups | 4 (4 ÷ 20 = 20% of clicks) | 9 (9 ÷ 45 = 20% of clicks) |
Post A has more reach and likes, but Post B brings more than twice as many sign-ups, because it reached people with the actual problem. Lena spends 5 hours per week on social media and values her time at €30 per hour: 5 × €30 × 4 weeks = €600 per month. That month she gained 26 sign-ups from social media. Cost per sign-up: €600 ÷ 26 ≈ €23.08. Excluded: tools, ads, and sales made later.
Common mistake
Practice activity
On paper: a post reached 2,400 accounts and received 84 interactions and 36 link clicks. Six people signed up for your newsletter. (1) Calculate the engagement rate by reach, the click rate and the sign-up rate. (2) A partner company pays you €200 to mention its tool in a post. What must you do before publishing, under German rules?
Show solution
(1) Engagement rate: 84 ÷ 2,400 = 3.5%. Click rate: 36 ÷ 2,400 = 1.5%. Sign-up rate: 6 ÷ 36 ≈ 16.7%. (2) Because you receive payment from another company, the post must be clearly labelled as advertising, for example with "Werbung" or "Anzeige", visible at first glance and not hidden among hashtags. Check the current rules for details.
Limitations: one post is a tiny sample; compare averages over many posts before you change your strategy.
Key takeaways
- Choose one or two platforms where your niche already discusses its problem
- Measure engagement rate, click rate and cost per sign-up with consistent definitions
- Followers and likes are vanity metrics; move people to your website and email list
- Label paid collaborations clearly in Germany and check the current UWG rules
