What are the most common mistakes when creating a free online store?
Not optimizing product photos
Blurry or poorly lit photos scare away customers. Use natural light, clean background and show the product from multiple angles. You don't need a professional camera, your phone is enough.
Generic product descriptions
Avoid descriptions like 'Nice t-shirt'. Use Marea Alcalina's AI description generator to create persuasive copy that highlights benefits and materials.
Not showing visible prices
Customers abandon catalogs without prices. Always display the price for each product. If you have variable pricing, show the range or starting price.
Not promoting your store
Creating the store is just the first step. Share your link on your WhatsApp status, Instagram stories, Facebook posts and TikTok bio every day.
Not responding to orders quickly
Customers ordering via WhatsApp expect a response in minutes, not hours. Set up quick replies and stay alert to your notifications.
How to maximize sales with your online store?
Update your catalog frequently
Add new products, update prices and refresh photos regularly. An active catalog builds more trust than a static one. Marea Alcalina's AI helps you create new descriptions quickly.
Use your store's QR code
Generate a QR code for your catalog with Marea Alcalina's free generator. Print it on business cards, packaging, flyers and any physical materials.
Leverage WhatsApp statuses
Post on your WhatsApp status daily with your catalog link. Your contacts will see your products and can order with a single click.
Ask customers for reviews
After each sale, ask your customers to recommend you to their friends. Word of mouth via WhatsApp is the most powerful marketing channel for small businesses in Mexico.
When do I need a paid plan?
Building and designing your store is free; the paid plan comes in when you want the world to see it. These are the signs it's time:
You've finished your catalog and want to publish it, you need to receive WhatsApp orders, you want your own domain for your brand, you want to remove Marea Alcalina branding, or you need detailed analytics to optimize your sales.
- You've finished your catalog and want to publish it to start receiving orders
- You want a custom domain, advanced analytics, and more payment options
- Your catalog exceeds 30 products and you need better category organization
