Marketplaces often struggle with duplicate ads as many users create multiple accounts to dodge free ad restrictions. OLX, one of the largest classifieds in Eastern Europe, developed an ML tool to spot potential duplicates messing up with their SEO and UX. Yet, they needed a user-friendly interface to quickly show why an ad might be a copy.
Swift and resource-efficient - that’s how we’ve approached the challenge. Quick prototypes and real moderator tests saved time and gave us awesome insights. We automated ad similarity checks, implemented and pinpointed similarities, and enabled moderators to review lots of ads at once. Plus, we added the opportunity to source ads from all over the Internet. As an extra, we implemented a photo-ranging system to put on top the photos that were similar but shot from a different angle. To speed things up, we set up a peer review system, keeping moderators fast and motivated.
The outcome: a quick, effortless, error-free, and intuitive user interface that allowed moderators to effectively and quickly verify and decide whether the ad was duplicate or not. This collaboration highlights the added business value of partnering with Rebbix, delivering a solution that goes beyond expectations in speed, efficiency, and quality.
