ACOS (Advertising Cost of Sale) is the king of Mercado Libre Ads. It measures what percentage of your sales goes toward paying for advertising.
A low ACOS means high profitability. At Achalay, we don’t just look at the number—we actively manage it.
We analyze ACOS by product, campaign, and category to make smart decisions. We pause ads that aren’t profitable, boost those with a healthy ACOS, and adjust bids in real time to keep it under control at all times.
Our goal is simple: for you to sell more while spending less. That way, your advertising investment isn’t an expense—it’s the engine of your growth.
ROAS (Return on Ad Spend) is the other side of the coin. It tells you how many dollars you earned for every dollar you spent on advertising.
If you spend $1 and make $10, your ROAS is 10. It’s the clearest indicator of your campaigns’ effectiveness.
We work with you to set an ROAS goal that’s ambitious yet realistic for your industry. Then, our entire optimization strategy is aligned with that goal.
We aim to maximize your return on investment, ensuring that every campaign contributes positively to your business’s overall profitability. It’s not about selling at any cost—it’s about selling well.
This KPI measures what percentage of your total revenue on Mercado Libre comes from sales driven by advertising. It’s a perfect indicator for understanding the impact of your campaigns and how much your business relies on them.
A healthy percentage (generally between 15% and 30%) indicates that your ad campaigns are boosting your sales without cannibalizing organic traffic. At Achalay, we monitor this metric to find the perfect balance.
We aim for Ads to act as an accelerator—not your sole source of sales—ensuring sustainable and diversified growth for your store on the platform.
The CTR (Click-Through Rate) measures the relevance of your ads. It compares how many people view your ad to how many click on it.
A high CTR indicates that your product, your main photo, and your price are appealing to buyers. Although it’s not a bottom-line business metric, it’s a key health indicator.
A low CTR can be a sign that the photo isn’t right, the price is out of line with the market, or the headline isn’t clear. We use it as an early diagnostic tool to optimize the creative elements of your ads and ensure they attract the right audience.
The Conversion Rate is the metric that ties everything together. It measures, out of all the people who clicked on your ad, how many ended up making a purchase.
It’s the ultimate indicator of the quality of your posts. You can have a very high CTR, but if nobody is buying, something is wrong.
We analyze the conversion rate by product to understand which posts are most effective. If we detect a low conversion rate, we dig deeper into the post: we review the photos, the description, questions from other users, and the competition to understand why clicks aren’t translating into sales, and we suggest specific improvements.
