The client
CEROIL is a Spanish brand of automotive additives and chemical mechanics. Its sales channel is Amazon.es, with a solid technical catalog that wasn’t reaching its full potential on the marketplace.
The challenge
CEROIL sells automotive additives and maintenance products on Amazon.es. Its catalog was solid, but the channel wasn’t taking off. In the first quarter of the last half-year the account billed €480.34 and moved 31 units: an average of €160 a month.
The problem wasn’t the product, it was visibility. The listings didn’t rank for relevant searches, the content failed to convey the value of a technical product, and the lack of reviews held back the conversion of a buyer who needs trust before applying a chemical to their engine.
How we did it
We worked the listing as a complete system: not a one-off optimization, but every Amazon lever activated in order and sustained over time.
Organic listing ranking
We restructured each listing’s keyword architecture: term research by volume and buying intent, backend keywords with no duplication and indexing work to appear in the searches that drive sales within the automotive category.
Titles and bullets
We rewrote the titles with the main keyword up front and a clear benefit. The bullets went from listing features to answering doubts: what the product does, which engine it’s for, what problem it prevents. Technical information translated into a buying decision.
A+ Content
We rolled out A+ Content on the main listings: visual modules explaining how to use the product, range comparisons and brand reinforcement. The buyer understands what they’re buying before reading a single review.
Reviews with Vine
We activated the Vine program to generate verified reviews on products with no history. Social proof is the number-one barrier in chemical mechanics: nobody pours an additive into their engine without knowing it worked for others.
Product videos
We added video to the listings: application demo and result. Video reduces the technical buyer’s uncertainty and increases time on the listing, two signals Amazon rewards in its ranking.
Coupons and deals
We scheduled coupons and one-off deals to accelerate sales velocity at key moments. More sales velocity feeds the organic ranking, which in turn brings more sales. The loop we were after.
Results
The last 30 days billed €1,072.68: the best month in the account’s history and 29% of everything sold in the half-year. The period comparison makes the jump clear:
Monthly revenue multiplied by 6.6 and quarterly units by 6.1. The conversion rate held between 6.6% and 6.9% while traffic grew, a sign that the increase in visibility didn’t dilute buyer quality.
What this case proves: on Amazon it’s not whoever does one thing well that wins, but whoever activates every listing lever at once and sustains them. Ranking, content, social proof and promotion working as a system. That’s the work that turned a stalled catalog into CEROIL’s best month.
