Mercado Livre: Full, reputation, and internal ads — the first 60 days
André Pimentel · 2026-10-07
If you’re just getting started on Mercado Livre, the Fulfillment (Full) service is a must. This means you should use the platform’s logistics to make sure your product gets to the customer quickly and efficiently. Full means faster delivery, which can positively impact the customer experience and, consequently, your reputation. Plus, products that use Full get more visibility in search results.
Title and photos
Your listing title should be clear and straightforward. Use keywords customers might search for. Try following this format: “Brand + Model + Specification”. For photos, use high-quality images with a neutral background. Include product shots from different angles, as well as images showing the product in use. A good title and attractive photos can increase your click-through rate (CTR) and improve your ranking.
High acos at the start
It’s normal for ACOS (Advertising Cost of Sales) to be high during the first few days. That’s because you’re still building your reputation and don’t have a sales history yet. A realistic starting ACOS range can be anywhere from 30% to 50%. Keep a close eye on it and adjust your internal ad campaigns to optimize this cost. Consider testing different creatives and targeting options to figure out what works best for your audience.
Reputation
Reputation is one of the most crucial factors for success on Mercado Livre. The reputation system is based on customer feedback and your issue resolution rate. During the first 60 days, make it a priority to respond quickly to questions and resolve any issues that come up. Great customer service can lead to positive reviews, which directly impact your reputation. Remember: the better your reputation, the more likely you are to make sales.
Ranking
Your Mercado Livre ranking is influenced by several factors, including price, reputation, response time, and using Full. To improve your position, analyze your competitors and adjust your prices to stay competitive. Internal ads are a great strategy to increase visibility and sales volume. Remember that Mercado Livre’s algorithm favors sellers who sell more, so invest in actions that can boost your sales during those first few days.
Combining these factors (Full, title and photos, ACOS management, reputation, and ranking) is essential for building a solid foundation during your first days selling on Mercado Livre.
