5 mistakes merchants make on social media (and how to avoid them)

Social media mistakes

Instagram and TikTok have become essential for local businesses in 2026. Yet many merchants struggle to get tangible results. Discover the 5 most common mistakes and, above all, how to avoid them.

Mistake #1: Posting without a defined strategy

The problem: Publishing content randomly, without a plan or clear objective. A restaurant shares a dish photo on Monday, nothing for 10 days, then three posts in a row on Saturday.

Why it matters: Instagram's algorithm favours accounts that post regularly. An inconsistent rhythm kills your organic reach and confuses your audience.

The solution: Create a simple editorial calendar. For example, for a restaurant:

  • Monday: Daily special photo
  • Wednesday: Behind-the-scenes Story
  • Friday: Signature dish Reel
  • Sunday: Customer testimonial or atmosphere

If you don't have time, delegate this task to local content creators via Kontnu who will create professional, regular content for you.

Mistake #2: Ignoring Stories and Reels

The problem: Sticking to classic feed posts and neglecting Instagram Stories and Reels/TikTok, which generate 10x more engagement.

The numbers speak: In 2026, Reels account for 50% of time spent on Instagram. Stories have an 80% completion rate vs 3% for classic posts. TikTok continues its rapid growth, particularly among 18-35 year-olds.

The solution: Adopt short video format:

  • Stories: Share your behind-the-scenes, your team, the day's atmosphere
  • Reels/TikTok: Show dish preparation, a before/after (salon), a transformation
  • Format: Vertical (9:16), 15-30 seconds, trending music

Mistake #3: Not engaging with your community

The problem: Publishing content but never responding to comments, private messages or mentions. Your community feels ignored and gradually loses interest.

The impact: A customer who asks a question in a comment and gets no reply has an 80% chance of never visiting your establishment. Worse, they may leave a negative review.

The solution:

  • Reply to ALL comments within 24h
  • Thank every mention in your Stories
  • Create Story polls to engage
  • Ask your audience questions ("What dish do you want to see next week?")

Spend 15 minutes a day on interaction — it's more effective than 2 hours of content creation with no engagement.

Mistake #4: Producing overly promotional content

The problem: Every post is a disguised ad: "Come eat with us!", "Exceptional offer!", "Best restaurant in Brussels!". This purely promotional content generates zero engagement.

Why it doesn't work: Users go on social media to be entertained, not to see ads. Overly commercial content gets scrolled past in 0.3 seconds.

The golden rule: 80% value-adding content, 20% promotion. Here are examples of value-adding content:

  • Educational: "How to choose the right wine to pair with your pasta"
  • Behind the scenes: "A day in the life of a chef" (timelapse video)
  • Human: Portrait of your team, the story of your business
  • Entertaining: Funny videos, adapted TikTok trends

Mistake #5: Not collaborating with local creators

The problem: Trying to do everything yourself when you have neither the time, the skills, nor the audience to create content that performs.

The reality: A local content creator with 5,000 to 20,000 followers generates on average 10,000 to 30,000 views per Reel. Their audience is engaged, local and matches your target exactly. A single Reel can bring you 20-50 new customers.

The advantages of collaboration:

  • Time saving: The creator handles everything (filming, editing, publishing)
  • Pro quality: Content optimised for Instagram/TikTok
  • Credibility: An influencer's recommendation is worth 10x more than an ad
  • Measurable ROI: You immediately see the impact on your footfall

Via Kontnu, you can collaborate with local creators without an advertising budget: you offer an experience (meal, treatment, product) and get professional content in 7 days.

In summary

Avoid these 5 mistakes and you'll see a significant improvement in your online presence:

  1. Post regularly according to a defined schedule
  2. Adopt Stories and Reels/TikTok
  3. Engage with your community daily
  4. Create value-adding content, not just promotional
  5. Collaborate with local content creators

The secret to social media success in 2026? Authenticity, consistency and collaboration. Businesses that have understood this generate 3x more customers than those clinging to traditional methods.
