Merchants: 5 digital actions under €500 that transform your revenue

"Digital is for big brands." This phrase comes up often among local merchants. Yet, with a few simple actions, a local business can see its revenue increase significantly in just a few months.

Here are the 5 most profitable actions, ranked by priority.

Action 1 — Optimize your Google Business Profile (0 €)

This is the most profitable action for local businesses. 87% of consumers use Google to find a local business.

What successful merchants do:

• Update storefront photos each season
• Keep hours always current (including holidays)
• Reply to EVERY Google review within 48 hours (even negative ones)
• Post a Google "post" once per week (new item, promotion, event)
• Fill in categories correctly (primary AND secondary)

Average result: +35% calls and +20% store visits within 3 months.

Cost: 0 €. Time: 20 minutes per week.

Action 2 — Create a WhatsApp Business catalog (0 €)

WhatsApp Business (free app, separate from regular WhatsApp) lets you:

• Create a product catalog with photos and prices
• Respond with automated messages (hours, rates)
• Send broadcast messages to consenting customers (new items, promotions)
• Accept orders directly by message

Real example: Many butchers, caterers and artisan food businesses now take weekend orders via WhatsApp. Feedback is unanimous: order volume increases significantly because customers are no longer held back by a busy phone line.

Cost: 0 €. Setup: 2 hours.

Action 3 — Launch a professional Instagram page (0 €)

Instagram isn't just for influencers. For a local business, it's a free storefront.

Effective minimal strategy:

• 3 posts per week (products, behind-the-scenes, team)
• Daily stories (even 15 seconds is enough)
• Local hashtags (#MontpellierShopping, #CommerceLyon, etc.)
• Link to Google Maps in your bio

Common mistake: create an account and stop posting after 2 weeks. Better to post 2 times regularly per week than 10 posts the first week then silence.

Cost: 0 €. Time: 30 minutes per week.

Action 4 — Set up a digital loyalty program (10-30 €/month)

Paper loyalty cards are over. Apps like Fidme, Zerosix or Pongo digitalize loyalty:

• Customer scans a QR code at each checkout
• You set the reward (free 10th coffee, -10% after 5 purchases)
• You send push notifications to bring back inactive customers

Average result: loyal customers spend 67% more than new customers (Bain & Company study).

Cost: 10 to 30 €/month depending on tool. ROI achieved in the first month.

Action 5 — Launch a local Google Ads campaign (150-300 €/month)

For businesses that want to accelerate, a Google Ads campaign targeted at your trade area is incredibly effective.

Typical setup:

• Radius: 5-10 km around your business
• Keywords: "[your activity] + [city]" (ex: "florist Montpellier")
• Budget: 5 to 10 € per day
• Ad with call extension (customer calls with one click)

Result: Fatima, the florist, invested 180 € in Google Ads in February 2025. Result: 47 phone calls, 23 orders, 2,800 € additional revenue. ROI: 15x.

Budget summary

With less than 250 € per month and 1.5 hours of weekly time, you transform the visibility and profitability of your business.
