Mercado Libre is not a side quest.

Mercado Libre is not a side quest.
If it is on the P&L as "test spend," you will run it like a hobby.
A CPG brand had $2,100 a month leftover in MLM after the Amazon budget was set.
Bids were copied from US Sponsored Products, then converted at the exchange rate.
That is not a market entry.
That is a leftover.
Mexico traffic does not behave like Amazon US:
→ CPCs started at $0.31 versus $1.64 on the same SKU family in the US
→ Mobile share was 94%
→ Installment-friendly titles converted 26% better than US-style premium titles
→ Search language clustered around use and pack, not brand poetry
→ Overnight bids borrowed from Eastern Time were on during the wrong hours
We rebuilt it as a real line:
→ Bid ceilings from local contribution, not from US ACOS
→ Native Spanish titles and the first three image slots
→ Mercado Pago installment callouts in the creative
→ A monthly contribution target of $8K, not "see what happens"
→ Same kill / keep / scale meeting as Amazon, not a side Slack thread
90 days later MLM was $11,400 in monthly spend and $19K in contribution.
Still smaller than the US.
Finally a business.
Bid strategy is the part US teams copy wrong.
US exact match at $1.80 does not become "good" at $0.40 just because the CPC is lower.
The ceiling still comes from local landed cost, local fees, and local conversion.
On this catalog, Mexico contribution per unit was $3.10, not the $8.40 they used in the US model.
That one substitution would have bid them into a hole.
Q4 US will eat attention.
That is exactly when LATAM accounts get neglected and then declared "not ready."
If you are going to be in Mercado Libre, put it on the same operating cadence as Amazon.
Leftover budget is not a strategy.
A bid model is.
